My CKEditor fields often contain lots of content with h1, h2, h3, etc headings, and I've written a script that presents all the headings in a sidebar for quick reference. I'd also like to use this sidebar as a navigation menu for the editor content, so clicking a heading in the sidebar scrolls the editor to the related heading, but I can't figure out how to wire it all up.
This post at https://davidwalsh.name/scroll-element-ckeditor leads me to believe that it should be possible, but I can't figure out how to get to the "editor" element described in the post.
My sidebar is built with jQuery from a CKEditor textarea with id="content" like this...
var content = $('<div/>').append($('#content').val());
var sidebar = "";
$(content).find('h1,h2,h3,h4,h5,h6').addClass('heading');
$(content).find('.heading').each(function () {
sidebar += this.outerHTML;
});
$('#sidebar').html(sidebar);
I imagine using jQuery :contains() to identify heading elements in the editor based on the text they contain, but I can't figure out how to hook back into the CKEditor instance in a way that enables this kind of DOM activity.
I am using CKEditor 4 but am happy to upgrade to version 5 if it offers a better solution to my problem.
Thanks!
This is what wound up working for me:
var content = $('<div/>').append($('#content').val());
var sidebar = "";
$(content).find('h1,h2,h3,h4,h5,h6').addClass('heading');
$(content).find('.heading').each(function () {
sidebar += this.outerHTML;
});
$('#sidebar').html(sidebar);
$('#sidebar .heading').click(function() {
var element = $('#cke_content iframe').contents().find(':contains(' + $(this).text() + ')')[2];
if (element) {
element.scrollIntoView();
}
});

Basically i have 2 instances of ckeditor on a single page. One on the left and another in the right side of the page.
The left editor uses a div rather than traditional iframe. I've done this by removing the iframe plugin and including the div editing area plugin.
The right editor loads in an iframe and but is also div based(i can use the iframe editor as well on the right if required, not an issue).
Now if the cursor/focus is on the right editor's content area then the left editor should scroll along with it. I've tried to use the code as provied by Reinmar in below url but it seems to work only with editors based on iframe on both sides. Also please note that i'm using jquery adapter for initializing the editors.
CKEDITOR how to Identify scroll event
I initialized the editor on left as below:
var editor_left = $( '#editor_left' ).ckeditor();
And below is my code for the right editor:-
var editor_right = $( '#editor_right' ).ckeditor();
editor_right.editor.on( 'contentDom', function() {
var editable = editor_right.editor.editable();
editable.attachListener( editable.getDocument(), 'scroll', function() {
alert('scroll detected');
parent.$('#left_editor_content_area').scrollTop($(this).scrollTop())
});
});
If i use the iframe based editor on the right then i'm able to get the "scroll detected" alert. But the scrollTop() function still does not work as expected
Any help will be appreciated.
The code that you mentioned is right. You got to update scrollTop property of the div-based editable with the scroll position of the window inside the iframe-based editor (JSFiddle).
var editor_div = CKEDITOR.replace( 'editor_div', {
extraPlugins: 'divarea'
} );
CKEDITOR.replace( 'editor_iframe', {
on: {
contentDom: function() {
var editable = this.editable(),
win = this.document.getWindow(),
doc = editable.getDocument();
editable.attachListener( doc, 'scroll', function( evt ) {
// Get scroll position of iframe-based editor.
var scroll = win.getScrollPosition();
// Update scroll position in the div-based editor.
editor_div.editable().$.scrollTop = scroll.y;
} );
}
}
} );
Excuse me for asking such a general question. I'm creating a website with Orchard CMS. The website's design and interactivity are critical requirements. I have a navigation menu which has a fixed size(900 px wide), but should be able to adjust as many menu items as possible (I do this manually by modifying the css). I've used a bit of jQuery to create some animations on mouse hovers etc. for the menu. Problem is that the css and jQuery parameters are hard coded. So if a user were to change to add a new menu item, they need to know in advance the number of menu items, and sub items, thus it's not very easy for the average user to customize it which the whole point of a CMS. What is the best way of keeping this menu interactive (with the jQuery animations), and such that the user can be able to add content pages to this menu (as they do with the default navigation menu in orchard) and also user friendly such that the non technical user need to have to mess around with the jQuery and CSS of the menu?
What is the best way of doing this, should I create a module (a navigation menu component?) which will dynamically set the css/jQuery values (width etc.)
UPDATE
Also, right now I have my HTML (my navigation menu, Unorderd List etc.) and its jQuery script reference embedded in my Layout.cshtml, and the style for the navigation menu is in my Site.css in my theme, is this considered bad practice?
I eventually got this done in orchard 1.5 by overriding the Menu.cshtml view, coding some logic to check the number of menu items and then rendering navigation menus with different ID's, based on the number of menu items they contained. I then added different CSS selectors in my Site.css, each with CSS suitable for navigation menus of various sizes. Here is what my Menu.cshtml ended up looking like (this goes in the Views folder of your currently active theme).
#
{
Script.Require("jQuery");
var tag = Tag(Model , "ul");
var items = (IList<dynamic>)Enumerable.Cast<dynamic>(Model.Items);
}
#{//if the menu contains 3 items, render a nav called 'ThreeItemNav'
if(items.Count == 3){
<nav id="ThreeItemNav">
#tag.StartElement
#* see MenuItem shape template *#
#DisplayChildren(Model)
#tag.EndElement
</nav>
}
else if(items.Count == 4){
<nav id="FourItemNav">
#tag.StartElement
#* see MenuItem shape template *#
#DisplayChildren(Model)
#tag.EndElement
</nav>
}
else if(items.Count == 5){
<nav id="FiveItemNav">
#tag.StartElement
#* see MenuItem shape template *#
#DisplayChildren(Model)
#tag.EndElement
</nav>
}
}
//Include the jQuery to add animations to the navigation menu
#using (Script.Foot())
{
<script type ="text/javascript">
//<![CDATA[
$(document).ready(function () {
//Add your script here
$(" #FiveItemNav li").hover(function () {
//Do something when the sub menu list items are hovered....
});
$(" #FourItemNav li").hover(function () {
//Do something when the sub menu list items are hovered....
});
$(" #ThreeItemNav li").hover(function () {
//Do something when the sub menu list items are hovered....
});
});
//]]>
</script>
}
Note that you need to add CSS selectors in your theme for each nav element (ThreeItemNav, FourItemNav and FiveItemNav), for example in your current themes Site.css:
/*Style the Three Item Navigation menu*/
#ThreeItemNav li
{
background-color:#263A79;
}
#ThreeItemNav a:hover
{
border-right:1px solid #333;
border-left:1px solid #333;
}
#ThreeItemNav > ul li.current
{
background:#5882FA;
}
/*Style the Four Item Navigation menu*/
#FourItemNav li
{
background:#Purple;
}
#FourItemNav a:hover
{
background:Orange;
}
.........more styles
This certainly seems like a long winded approach, but it's the best I could think off so that I can maintain the functionality of the Orchard navigation menu and still style it with CSS and add jQuery animations. I figured an initial development cost was worth adding some powerful capabilities to the navigation menu in the long run. I'd love to hear any suggestions on how to do this in a neater way. Also I would definitely recommend using Orchard 1.5, since it has built in support for creating hierarchical navigation menus.
Checking out the inner workings of Menu.cshtml and MenuItem.cshtml views help a lot in trying to understand how the navigation menus are rendered in Orchard as well as inspecting how the default Theme Machine styles the navigation menu and its various levels/sub menus.
I am using Asp.Net MVC3, for a project.
In one of the page, I am using MS Charts. In View I have a Image which shows the chart as follows:
<img src="#Url.Action("RenderCharts", "Home", new
{
XAxisColor = ViewBag.XAxisColor,
YAxisColor = ViewBag.YAxisColor,
})" alt="Charts" runat="server" />
I have 2 CheckBoxes, which is used to change Chart Axes Colors. When the checkbox is clicked, page is submitted and checkbox status is stored and based on that Chart is rendered:
bool XAxisColor = (#ViewBag.XAxisColor) ?? true;
bool YAxisColor = #ViewBag.YAxisColor ?? false;
#Html.CheckBox("chkXAxisColor", XAxisColor, new { #Id = "chkXAxisColor",
onClick = "this.form.submit();" })
X Axis Color
#Html.CheckBox("chkYAxisColor", YAxisColor, new { #Id = "chkScatter",
onClick = "this.form.submit();" })
Y Axis Color
When first time the page is loaded, RenderCharts() Action gets called and Chart is rendered.
But when i Click any of the CheckBox, RenderCharts() Action gets called twice.
I could not understand this issue. I have created a sample Application which can be downloaded from here https://www.dropbox.com/s/ig8gi3xh4cx245j/MVC_Test.zip
Any help would be appreciated. Thanks in advance.
This appears to be something to do with Internet Explorer. Using your sample application, everything works fine in both Google Chrome and Firefox, but when using IE9, there are two Action requests on a postback.
Using the F12 developer tools on the network tab, it shows an initial request to RenderCharts which appeared to be aborted:
The (aborted) line in the middle is, I suspect, the additional request you're seeing. Why this happens, I don't know!
Finally got the answer. The problem was
runat="server"
in the Img tag.
Removing runat fixed the issue.
I can eliminate the IE issue in the following manner by simply using a bit of JQuery instead. A few possible advantages...
It eliminates the cross-browser issue.
It is an unobtrusive approach (not mixing javascript and HTML in the view).
You can update the image via ajax.
Create a new file in the scripts folder (e.g. "chart.js") which will simply attach an anonymous function to the the click events of your checkboxes from the document ready function. You would obviously need to include the script reference in your page as well:
$(document).ready(function () {
// Attach a function to the click event of both checkboxes
$("#chkXAxisColor,#chkScatter").click(function () {
// Make an ajax request and send the current checkbox values.
$.ajax({
url: "/Home/RenderCharts",
type: "GET",
cache: false,
data: {
XAxisColor: $("#chkXAxisColor").attr("checked"),
YAxisColor: $("#chkScatter").attr("checked")
},
success: function (result) {
alert(result);
$("#chart").attr("src", result);
}
});
});
});
Best of all, you get to eliminate the javascript from your view :)
...
<div style="margin: 2px 0 2px 0">
#Html.CheckBox("chkXAxisColor", XAxisColor, new { #Id = "chkXAxisColor" })
X Axis Color
#Html.CheckBox("chkYAxisColor", YAxisColor, new { #Id = "chkScatter" })
Y Axis Color
</div>
...
This is of course a very basic example which does eliminate the IE issue but you could get fancier from there in terms of how you update the image + show a loading gif, etc with only a few more lines.
Hopefully it is a workable solution for you!
I am developing a website that parses rss feeds and displays them based on category. You can view it here: http://vitaminjdesign.com/adrian
I am using tabs to display each category. The tabs use ajax to display a new set of feeds when they are clicked.
I am also using two other scripts- One called equalheights, which re-sizes all of the heights to that of the tallest item. And the other script I am using is called smart columns, which basically resize your columns so it always fills the screen.
The first problem I am having is when you click a new tab (to display feeds within that category). When a new tab is clicked, the console shows a jQuery error:
$(".block").equalHeights is not a function
[Break On This Error] $(".block").equalHeights();
The main problem is that each feed box fills up the entire screen's width (after you click on a tab), even if there are multiple feed boxes in that category.
MY GUESS - although all of the feeds (across all tabs) are loaded on pageload, when a new tab is selected, both jQuery scripts need to be run again. any ideas on how I can make this work properly?
One thing to note - I used the ajaxSuccess method for making equalHeights work on the first page...but it wont work after a tab is clicked.
My jQuery code for the tabs are below:
$(".tab_content").hide(); //Hide all content
$("ul.tabs li:first").addClass("active").show(); //Activate first tab
$(".tab_content:first").show(); //Show first tab content
$("#cities li:nth-child(1)").addClass('zebra');
$("#column li ul li:nth-child(6)").addClass('zebra1');
//On Click Event
$("ul.tabs li").click(function() {
$("ul.tabs li").removeClass("active"); //Remove any "active" class
$(this).addClass("active"); //Add "active" class to selected tab
$(".tab_content").hide(); //Hide all tab content
var activeTab = $(this).find("a").attr("href"); //Find the href attribute value to identify the active tab + content
$(activeTab).fadeIn(); //Fade in the active ID content
$(".block").equalHeights();
return false;
});
Thanks to Macy (see answer below), I have brought my jQuery script to the following: (still does not work)
$(document).ajaxSuccess(function(){
var script = document.createElement('script');
script.src = 'js/equalHeight.js';
document.body.appendChild(script);
equalHeight($(".block"));
I found some small problems in your code. I am not sure that my suggestions will solve all the problems, but I decide to describe my first results here.
1) You should remove comma before the '}'. Currently the call look like $("#column").sortable({/**/,});
2) The function equalHeight is not jQuery plugin. It is the reason why the call $(".block").equalHeights(); inside your 'click' event handler follows to the error "$(".block").equalHeights is not a function" which you described. You should change the place of the code to equalHeight($(".block")); like you use it on other places.
3) The script http://vitaminjdesign.com/adrian/js/equalHeight.js defines the function equalHeight only and not start any actions. Once be loaded it stay on the page. So you should not load it at the end of every ajax request. So I suggest to reduce the script
$(document).ajaxSuccess(function(){
var script = document.createElement('script');
script.src = 'http://vitaminjdesign.com/adrian/js/equalHeight.js';
document.body.appendChild(script);
equalHeight($(".block"));
$("a[href^='http:']:not([href*='" + window.location.host + "'])").each(function() {
$(this).attr("target", "_blank");
});
});
to
$(document).ajaxSuccess(function(){
equalHeight($(".block"));
$("a[href^='http:']:not([href*='" + window.location.host + "'])").each(function() {
$(this).attr("target", "_blank");
});
});
4) I suggest to change the code of http://vitaminjdesign.com/adrian/js/equalHeight.js from
function equalHeight(group) {
tallest = 0;
group.each(function() {
thisHeight = $(this).height();
if(thisHeight > tallest) {
tallest = thisHeight;
}
});
group.height(tallest);
}
to
function equalHeight(group) {
var tallest = 0;
group.each(function() {
var thisHeight = $(this).height();
if(thisHeight > tallest) {
tallest = thisHeight;
}
});
group.height(tallest);
}
to eliminate the usage of global variables tallest and thisHeight. I recommend you to use JSLint to verify all your JavaScript codes. I find it very helpful.
5) I recommend you to use any XHTML validator to find some small but sometime very important errors in the markup. Try this for example to see some errors. The more you follow the XHTML standards the more is the probability to have the same results of the page in different web browsers. By the way, you can dramatically reduce the number of the errors in your current code if the scripts included in the page will be in the following form
<script type="text/javascript">
//<![CDATA[
/* here is the JavaScript code */
//]]>
</script>
I didn't analysed the full code but I hope that my suggestions will solve at least some of problems which you described in your question.
Essentially, when you add a new element to the document, the equalheights script has not attached its behavior to that new element. So, the "quick fix", is probably to re-embed the equalheights script after an ajax request has completed so that it re-attaches itself to all elements on the page, including the elements you just added.
Before this line: $(".block").equalHeights(); , add a line of script which re-embeds/re-runs your equalheights script.
$.getScript('<the location of your equalHeightsScript>');
$.getScript('<the location of your smartColumnsScript>');
$(".block").equalHeights();
or
var script = document.createElement('script');
script.src = '<the location of your script>';
document.body.appendChild(script);
A better solution would be to upgrade the plugin so it takes advantage of live. However, I'm not up to that at the moment :)
Some Error Here
$("ul.tabs li").click(function() {
$("ul.tabs li").removeClass("active"); //Remove any "active" class
$(this).addClass("active"); //Add "active" class to selected tab
$(".tab_content").hide(); //Hide all tab content
.
.
.
});
Should be re-written like this
$("ul.tabs li").click(function() {
$(this).addClass("active").Siblings("li").removeClass("active");; //Remove any "active" class Add "active" class to selected tab
$(".tab_content").hide(); //Hide all tab content
.
.
.
});
I don't think you need to run the scripts again after the ajax, or at least that's not the "main" problem.
You seem to have some problems in the script smartColumn.js
Right now it seems to only operate on the ul with the id "column" ('#column'), and it is working on the one UL#column you do have, but of course your HTML has many other "columns" all of which have the class "column" ('.column') that you want it to work on as well.
Just to get the beginning of what you are trying to do, change all the selectors in smartColumn.js that say 'ul#column' to say 'ul.column' instead, and then alter the HTML so that the first "column" has a class="column" rather than an id="column".
That should solve the 100% wide columns at least.
That should solve your "Main" Problem. But there are other problems.
I'm attempting to place an image map into a jQuery UI dialog. Initially, the and are hidden on the page so that I don't have to do any AJAX. When the dialog is triggered, the and are placed in the dialog and the hidden original content has its link to the image map removed.
There are a few links on the image map in tags and in Firefox, Chrome etc the links are positioned correctly and work.
However, in all versions of IE (the web site is SharePoint 2007 and compatibility mode is on), the links do not fire on the image map. You can hover over the rectangles and be shown the link, but the action never fires.
Code used to initialise below:
$(document).ready(function() {
$('.processDiagram').click(function() {
var phase = $(this).attr('title');
var text = $('#'+phase+' div').html();
var mapname = $('#'+phase+' map').attr('name');
$('#'+phase+' map').attr('name', ''); // null out the background map name so it doesn't get confused
var $dialog = $('<p></p>').html(text).dialog({modal:true, autoOpen:false, width:620, title:phase, beforeClose: function(event, ui) { $('#'+phase+' map').attr('name', mapname); }});
$dialog.dialog('open');
return false; // So firefox won't just follow the link
}
}
I could really do with some help here as I have no idea why the links aren't firing.
Thanks,
Steve
So, the reason is the layout being position:relative does a number on IE, moving all of the hotspots to be relative to the body and not to the image map itself.
Solution is to fix that layout issue.
