Does anyone know how to integrate the Oracle Jet Gantt chart into Oracle Apex version 5.1? The research I have done shows either how to integrate Jet components into version 5.0 (but to my understanding, a lot changed between versions 5.0 and 5.1, specifically with regards to the Oracle JET library) or how to integrate a couple of different Oracle Jet components into Apex 5.1, but the code used to integrate these components seems very specific to the components being integrated. I have tried copying and pasting the javascript code and the HTML code from the Oracle Jet Cookbook into the the appropriate sections in the Page Designer on Apex, but nothing shows up when I run the page. Specifically, I'm wondering how to use the Oracle Jet cookbook code for the Gantt chart to create that Gantt chart on a page in my Apex application?
Has anyone tried to do this yet?
Thank you in advance.
If you do not find a plugin, you can use oracle-jet gantt by making direct references using a CDN to the files on your apex page.
1 - First upload the main.js file to the shared components of your application. He must follow these guidelines https://docs.oracle.com/middleware/jet400/jet/developer/GUID-219A636B-0D0B-4A78-975B-0528497A82DD.htm#JETDG-GUID-219A636B-0D0B-4A78-975B-0528497A82DD
Your main.js look like this:
/*
* To change this license header, choose License Headers in Project Properties.
* To change this template file, choose Tools | Templates
* and open the template in the editor.
*/
function _getCDNPath(paths) {
var cdnPath = "";
var ojPath = "";
var thirdpartyPath = "";
var keys = Object.keys(paths);
var newPaths = {};
function _isoj(key) {
return (key.indexOf('oj') === 0 && key !== 'ojdnd');
}
keys.forEach(function(key) {
newPaths[key] = cdnPath + (_isoj(key) ? ojPath : thirdpartyPath) + paths[key];
});
return newPaths;
}
require.config({
paths: _getCDNPath({
'knockout': 'https://static.oracle.com/cdn/jet/v4.0.0/3rdparty/knockout/knockout-3.4.0',
'jquery': 'https://static.oracle.com/cdn/jet/v4.0.0/3rdparty/jquery/jquery-3.1.1.min',
'jqueryui-amd': 'https://static.oracle.com/cdn/jet/v4.0.0/3rdparty/jquery/jqueryui-amd-1.12.0.min',
'ojs': 'https://static.oracle.com/cdn/jet/v4.0.0/default/js/min',

})
})
requirejs.config({
baseUrl: '',
// Path mappings for the logical module names
paths: {
},
// Shim configurations for modules that do not expose AMD
shim: {
'jquery': {
exports: ['jQuery', '$']
},
'maps': {
deps: ['jquery', 'i18n'],
}
},
// This section configures the i18n plugin. It is merging the Oracle JET built-in translation
// resources with a custom translation file.
// Any resource file added, must be placed under a directory named "nls". You can use a path mapping or you can define
// a path that is relative to the location of this main.js file.
config: {
ojL10n: {
merge: {
//'ojtranslations/nls/ojtranslations': 'resources/nls/menu'
}
}
}
});
2 - Now you need to load this file (main.js) and require.js on your page. Use the "File URLs" field for this.
require.js: https://static.oracle.com/cdn/jet/v4.0.0/3rdparty/require/require.js
3 - In the header of your page you need to include this code:
<link rel="stylesheet" id="css" href="https://static.oracle.com/cdn/jet/v4.0.0/default/css/alta/oj-alta-min.css">
<script>
if (!document.createElement) {
document.createElement = document.constructor.prototype.createElement;
document.createElementNS = document.constructor.prototype.createElementNS;
document.importNode = document.constructor.prototype.importNode;
}
// The "oj_whenReady" global variable enables a strategy that the busy context whenReady,
// will implicitly add a busy state, until the application calls applicationBoostrapComplete
// on the busy state context.
window["oj_whenReady"] = true;
</script>
4 - Create a region to place the html of your oracle-jet chart
5 - Finally, create a dynamic action to effectively create your gantt chart. The dynamic action event is page loading. It should run a javascript code. This code is the file demo.js on cookbook site.
Ex. https://apex.oracle.com/pls/apex/f?p=145794:23
login on: https://apex.oracle.com/pls/apex/f?p=4550
workspace: stackquestions
user: test
pwd: test
app: 145794
page: 23
Once you make this work, your problem will be how to get the data and update the gantt depending on some filters. I suggest creating a restful service to get this data from your tables. For this you will need some javascript handling to make your data follow the format expected by oracle-jet. You can see the expected format in the ganttData.json file.
Good luck.
I noticed that the css file needed to make the oracle-jet work interferes with the page's css. I tried to use this idea Limit scope of external css to only a specific element? but it did not work completely.
why just not take a plugin ? either write your own or look at apex.world for the gantt plugin

I want to change group of CSS items in jqGrid. Documentation is saying
Of course if we want to change not only one CSS item from a group, but two or more we can use jQuery extend to do this:
var my_col_definition = {
icon_move : 'ui-icon-arrow-1',
icon_menu : "ui-icon-pencil"
}
$.extend( $.jgrid.styleUI.jQueryUI.colmenu , my_col_definition );
And this is working partially. But I want to override all icons in my Bootstrap with next code:
$.extend($.jgrid.styleUI.Bootstrap, {
common: {
icon_base: "fa"
},
inlinedit: {
icon_edit_nav: "fa-edit"
},
navigator: {
icon_edit_nav: "fa-edit"
},
// ...
});
and my grid stops working and does not respond to any commands. There are no errors in console.
Do anybody know how to fix the problem in an elegant way and do not override every group separately?
It is unknown which versions of Guriddo jqGrid and Bootstrap are used.
I see you try to use the fontAwesome.
With the last release you can use fontAwesome with ths following settings:
<script>
$.jgrid.defaults.styleUI = 'Bootstrap4';
$.jgrid.defaults.iconSet = "fontAwesome";
</script>
And point to the needed css files as described in this documentation
You can change the icons the way you do in your code without problems - I have tested this and it works.
In any case, please prepare a simple demo which reproduces the problem, so that we can look into it.
I have tried to add justify plugin to be able to align text right, left or centre. But after following the instructions in the documentation (http://apostrophecms.org/docs/tutorials/howtos/ckeditor.html), I wonder if the plugin should be located in a specific folder (mine is at public/modules/apostrophe-areas/js/ckeditorPlugins/justify/), as it disappears when the site is loaded, but if I include it in some other folder such as public/plugins/justify still doesn't work.
This is my code just in case: (located at lib/modules/apostrophe-areas/public/js/user.js)
apos.define('apostrophe-areas', {
construct: function(self, options) {
// Use the super pattern - don't forget to call the original method
var superEnableCkeditor = self.enableCkeditor;
self.enableCkeditor = function() {
superEnableCkeditor();
// Now do as we please
CKEDITOR.plugins.addExternal('justify', '/modules/apostrophe-areas/js/ckeditorPlugins/justify/', 'plugin.js');
};
}
});
Also, it would be nice to know how the plugin should be called at the Toolbar settings for editable widgets.
Thanks!
The URL you need is:
/modules/my-apostrophe-areas/js/ckeditorPlugins/justify/
The my- prefix is automatically prepended so that the public folders of both the original apostrophe-areas module and your project-level extension of it can have a distinct URL. Otherwise there would be no way for both to access their user.js, for instance.
I'll add this note to the HOWTO in question, which currently handwaves the issue by stubbing in a made-up URL.
As for how the plugin should be called, use the toolbar control name exported by that plugin — that part is a ckeditor question, not really an Apostrophe one. But looking at the source code of that plugin they are probably JustifyLeft, JustifyCenter, JustifyRight and JustifyBlock.
It turns out that it's not enough to simply call CKEDITOR.plugins.addExternal inside apostophe-areas. You also need to override self.beforeCkeditorInline of the apostrophe-rich-text-widgets-editor module and explicitly call self.config.extraPlugins = 'your_plugin_name';.
Here's what I ended up with:
In lib/modules/apostrophe-areas/public/js/user.js:
apos.define('apostrophe-areas', {
construct: function(self, options) {
// Use the super pattern - don't forget to call the original method
var superEnableCkeditor = self.enableCkeditor;
self.enableCkeditor = function() {
superEnableCkeditor();
// Now do as we please
CKEDITOR.plugins.addExternal('justify', '/modules/my-apostrophe-areas/js/ckeditorPlugins/justify/', 'plugin.js');
};
}
});
then in in lib/modules/apostrophe-rich-text-widgets/public/js/editor.js:
apos.define('apostrophe-rich-text-widgets-editor', {
construct: function(self, options) {
self.beforeCkeditorInline = function() {
self.config.extraPlugins = 'justify';
};
}
});
For some reason doing CKEDITOR.config.extraPlugins = 'justify' inside apostrophe-areas does not work, probably due to the way how CKEDITOR is initialized;
One more thing: this particular plug-in (justify, that is) does not seem to follow the button definition logic. It has button icons defined as images, whereas CKEditor 4.6 used in Apostrophe CMS 2.3 uses font-awesome to display icons. It means that the icons that ship with the justify module won't be displayed and you'll have to write your own css for each button individually.
There is another issue which you'll probably face when you finally enable the justify buttons. The built-in html sanitizer will be strip off the styles justify adds to align the content.
Apostrophe CMS seems to be using sanitize-html to sanitize the input, so changing CKEditor settings won't have any effect. To solve the issue, add the following to your app.js:
'apostrophe-rich-text-widgets': {
// The standard list copied from the module, plus sup and sub
sanitizeHtml: {
allowedAttributes: {
a: ['href', 'name', 'target'],
img: ['src'],
'*': ['style'] //this will make sure the style attribute is not stripped off
}
}
}
Thank you both for your help. After following both approaches of: locating the plugin at my-apostrophe-areas folder as well as editing editor.js on the apostrophe-rich-text widget (the sanitize.html file was already using that configuration), I got the plugin working. However, I was still having the issue with the icons.
I fixed that adding the Font Awesome icons that correspond to align-justify, align-right, align-left and align-center at the end of public/modules/apostrophe-areas/js/vendor/ckeditor/skins/apostrophe/editor.less
Hi I'm using dojo in amd mode for my main app (html page). I would like to create a module that references d3 library to create some charts. I'm having trouble creating this module -- what I've got so far for the module (a javascript file) is this:
define(["d3"], function (d3) {
return {
setd3ChartData: function () {
//this function can be called from my main app
//but d3 isnt linked to the d3 js library
}
}
});
in my main app I've got a link to the d3 libary in a script tag
How can I get this script link into the module? I can access d3 library just fine from main app
Thanks
Pete
When you want to use D3 with Dojo you probably first want to define the D3 package in your Dojo config. For example (when using a CDN):
<script type="text/javascript">
var dojoConfig = {
async: true,
parseOnLoad: true,
packages: [{
name: "d3",
location: "http://cdnjs.cloudflare.com/ajax/libs/d3/3.4.6/"
}]
}
</script>
Then you can use D3 by using:
require([ "d3/d3" ], function(d3) {
// Do stuff with "d3"
});
The reason you have to use "d3/d3" and not just "d3" is that the part before the / indicated the package name, in this case it's d3 (which we configured using dojoConfig).
The second part is the actual file, or in this case d3.js.
I also made a JSFiddle to show a working example of D3 loaded using the AMD loader. In that example I placed the Dojo configuration under the Fiddle options, but the setup is the same.
I also renamed the callback to d3Lib, because D3 by defaults creates the d3 global variable and now you can clearly see it's working with AMD.
If you want to use the minified version you can load "d3/d3.min".
var currentDialog = CKEDITOR.dialog.getCurrent();
currentDialog._.editor.insertHtml("<customTag myAttr='var'></customTag>");
Throws an error, TypeError: Cannot read property 'isBlock' of undefined
If I try .insertHtml("<span>hello</span>") it works just fine.
How can I change ckeditor to allow me to specify my own custom html tags via .insertHtml()? I'd love to just change it to be something like <span class='custom'... or something like that, but I'm having to deal with legacy CMS articles. Using latest ckeditor. Thanks.
You need to modify CKEDITOR.dtd object so editor will know this tag and correctly parse HTML and process DOM:
CKEDITOR.dtd.customtag = { em:1 }; // List of tag names it can contain.
CKEDITOR.dtd.$block.customtag = 1; // Choose $block or $inline.
CKEDITOR.dtd.body.customtag = 1; // Body may contain customtag.
You need to allow for this tag and its styles/attrs/classes in Advanced Content Filter:
editor.filter.allow( 'customtag[myattr]', 'myfeature' );
Unfortunately, due to some caching, in certain situations you cannot modify DTD object after CKEditor is loaded - you need to modify it when it is created. So to do that:
Clone the CKEditor repository or CKEditor presets repository.
Modify core/dtd.js code.
And build your minified package following instructions in README.md - the only requirements are Java (sorry - Google Closure Compiler :P) and Bash.
PS. That error should not be thrown when unknown element is inserted, so I reported http://dev.ckeditor.com/ticket/10339 and to solve this inconvenience http://dev.ckeditor.com/ticket/10340.
I worked around this issue with a combination of createFromHtml() and insertElement()
CKEDITOR.replace('summary', { ... });
var editor = CKEDITOR.instances.summary;
editor.on('key', function(ev) {
if (ev.data.keyCode == 9) { // TAB
var tabHtml = '<span style="white-space:pre"> </span>';
var tabElement = CKEDITOR.dom.element.createFromHtml(tabHtml, editor.document);
editor.insertElement(tabElement);
}
}
I have recently asked where global stylesheets are for editing Cognos 10 styles (Here).
After some discussions with our team we would like to find the CGI or base imported file that Cognos uses to construct it's report viewer pages and dashboard widget holders.
The reason we want to do this is so that we can include all our custom style and javascript in one location. When/If we upgrade Cognos we can be sure of one point of failure with our reports. This would solve our problem of having to re-edit multiple stylesheets (and javascript).
I'm normally familiar with ASP.NET and not CGI-BIN. Is there something akin to a Master page where styles and basic imports are done for a Cognos page? Ideally editing this file would allow us to continue our customizations.
Can this be done? Or are we just insane? We understand the risks concerning upgrades, but are OK with the risks (unless someone can provide a good example of how this technique would not be replicated via version changes).
I think it's fairly common that BI professionals with more traditional web development backgrounds like me and you have no qualms with making changes to the global CSS files and bringing in more JS.
I've explained to you how I run JS in a report - I'd love to add jQuery to our global libraries, but I haven't drummed up enough support for it yet. I can help with the CSS portion though.
In 8.4.1, there's a ton of CSS files referenced by the report viewer. If I were you, I'd render a sample report with the default styling and use Firebug or similar to trace the CSS files being called. You'll find that server/cognos8/schemas/GlobalReportStyles.css is commonly referenced, with some help from server/cognos8/skins/corporate/viewer/QSRVCommon.css - there's also some other files in there that are imported.
I'd imagine you could grep -R '<link rel=\"stylesheet\" type=\"text/css\" href=\"../schemas/GlobalReportStyles.css\"> in the COGNOS directory to see where the file is being called, and either edit that file directly, or create a link to your own JS. Personally, I'd just backup the existing stylesheet and modify the one that is already there.
I'd imagine you could do something similar for the JS - find where it's being called in the template (using grep) and just create a new reference to the file you'd like to create. In my case, I'd do a backflip if I could get jQuery loaded into every report.
Just realized this is a year old. :-( Sorry, first time here. I'll leave it in case anyone is still interested in the topic.
Here is the documentation on customizing Cognos on several levels:
We used an alternative to modifying the system files. We have a shared component "report" containing an HTML object with our particular CSS overrides on it, and/or a link to a custom stylesheet. We then add this on each report with a "Layout Component Reference" from the toolbox. If we want a global change, just change the one item in the component report or custom stylesheet. This works very well for us.
I up-voted both the previous answers to this question. I'll admit I kind of forgot about this question till someone put some activity on it.
We ended up doing a combination of the above techniques. I was able to find the global stylesheets as suggested. What I ended up doing was copying out all the styles that were in that stylesheet and created a new sheet suffixed with *_SystemSytles.css*. I created a second sheet and suffixed it with *_Custom.css*. Then in the original sheet I placed two imports, first importing the system styles and then the custom styles.
For certain reports we have a custom object that is dropped on that brings in its own styles (and JavaScript). This utilizes a similar technique to the second question.
However, what I had to do for import the JavaScript for general use within the entire Cognos site was difficult.
In the core webcontent folder I created a js folder that contained the jQuery and our custom JavaScript files. Then in a series of JavaScript files I included code similar to the following:
/************************
JQUERY UTIL INCLUDE
************************/
function loadjscssfile(filename, filetype, id) {
if (filetype == "js") { //if filename is a external JavaScript file
var fileref = document.createElement('script')

if (id)
fileref.setAttribute("OurCompanyNameAsAnID", id)
}
else if (filetype == "css") { //if filename is an external CSS file
var fileref = document.createElement("link")
fileref.setAttribute("rel", "stylesheet")
fileref.setAttribute("type", "text/css")
fileref.setAttribute("href", filename)
}
if (typeof fileref != "undefined") {
var headTag = document.head || document.getElementsByTagName('head')[0];
headTag.appendChild(fileref);
}
}
function _PortalLoadJS() {
if (!window._PortalScriptsLoaded) {
var pathParams = [];
var path = location.href;

var e,
r = /([^/]+)[/]?/g,
p = path;
while (e = r.exec(p)) {
pathParams.push(e[1]);
}
})();
var baseURL = location.protocol + '//';
for(var i = 1; i < pathParams.length; i++) {
if(pathParams[i] == 'cgi-bin')
break;
baseURL += pathParams[i] + '/';
}
loadjscssfile(baseURL + "js/jquery-1.6.1.min.js", "js");
loadjscssfile(baseURL + "js/Custom.js?pageType=COGNOS_CONNECTION", "js", "SumTotalUtil");
window._PortalScriptsLoaded = true;
}
}
if(!window.$CustomGlobal) {
window.$CustomGlobal= function(func) {
if (!window.$A) {
if (!window.__CustomExecStack) {
window.__CustomExecStack= new Array();
}
window.__CustomExecStack.push(func);
}
else
$A._executeCustomItem(func);
}
}
try {
// Catch cases where $(document).ready() is called after the
// browser event has already occurred.
if (document.readyState === "complete") {
// Handle it asynchronously to allow scripts the opportunity to delay ready
setTimeout(_PortalLoadJS, 10);
}
// Mozilla, Opera and webkit nightlies currently support this event
if (document.addEventListener) {
// Use the handy event callback
document.addEventListener("DOMContentLoaded", function() { _PortalLoadJS(); }, false);
// A fallback to window.onload, that will always work
window.addEventListener("load", _PortalLoadJS, false);
// If IE event model is used
} else if (document.attachEvent) {
// ensure firing before onload,
// maybe late but safe also for iframes
document.attachEvent("onreadystatechange", function() { _PortalLoadJS(); });
// A fallback to window.onload, that will always work
window.attachEvent("onload", _PortalLoadJS);
}
}
catch (ex) { }
The $A item is an item that I create when the Custom.js file is loaded.
Here are the list of files that I've included this code (at the vary end of the JavaScript):
webcontent\icd\bux\js\bux\bux.core.js
webcontent\ps\portal\js\cc.js
webcontent\rv\CCognosViewer.js
webcontent\rv\GUtil.js
webcontent\rv\viewer.standalone.core.js
These files should cover the Cognos Connection, Report Viewer, and the Dashboards area. If any more are found please let me know and I can update this list.
When linking to the Custom.js file I put a query string on the external resource that the Custom.js file picks up: pageType=COGNOS_CONNECTION. This allows me to do specific load code for the Cognos Connection, Report Viewer, or the Dashboards.
Here is the code in the Custom.js class that inits the $A object:
function _CustomUtilInit() {
try {
if (!window.$j) {
window.setTimeout(_CustomUtilInit, 1);
return;
}
var jScriptTags = $j('SCRIPT[' + Analytics.SCRIPT_ATTR_NAME + '= ' + Analytics.SCRIPT_ATTR_VALUE + ']');
jScriptTags.each( function(i, scriptElem) {
var tag = $j(scriptElem);
if(tag.attr(Analytics.LOADED_SCRIPT_KEY))
return;
var scriptURL = new URI(tag.attr('src'));
var analyticsPageType = scriptURL.getQueryStringValue(Analytics.PAGE_TYPE_QUERY_KEY, Analytics.PageType.REPORT_VIEWER);
if(!window.$A) {
window.$A = new Analytics();
}
window.$A.init(analyticsPageType);
tag.attr(Analytics.LOADED_SCRIPT_KEY, 'true');
});
} catch (e) {
}
}
_CustomUtilInit();
Of course this expects that the jQuery libraries were included before the Custom.js files in each of the previously mentioned JavaScript files.
The URI class is something that I've found on the internet and tweaked for our use. If you have any questions regarding the custom JavaScript loading please leave a comment and I'll do my best to elaborate some more.
