I'm working on a Kendo Mobile project with a number of:
Kendo Views (external to root html)
Modal Views (in the root html).
The external files load on demand and everything works fine. But i'd like to have the same load on demand behavior for some of the modal views, because the root/based html file is becoming too large and not manageable.
Is there a way to either:
Store a modal view in an external file? If so is it possible to load via javascript syntax (app.navigate()) rather than the declarative syntax (href='externalmodal').
Manually pre-load an external view without navigating to it first.
This code lets you manually create a view:
var viewUrl = 'blahblahblah';
var element = $.parseHTML('<div data-role=view>test</div>')[0];
element.style.display = 'none';
$(document.body).append(element);
var options = $.extend({}, kendo.parseOptions(element, kendo.mobile.ui.View.fn.options));
var view = new kendo.mobile.ui.View(element, options);
view.element[0].setAttribute('data-url', viewUrl);
kendo.mobile.application.navigate(viewUrl, '');
Depending on what features you use, you may need to instead use code similar that that used for ModalView below so that Kendo creates the subclass (changes: substitute View for ModalView, substitute view for modalview, add data-url, remove call to show(), maybe check that view not already created by checking for element with matching data-url). We haven't tested setting roles.view this way, but we did something similar while testing this stuff out and it worked.
Don't try settings the options - Kendo got confused (at least trying to set useNativeScrolling didn't work, also don't try setting the options object on the subclass unless you really know what you are doing).
Caveat: This was using browserHistory:false (which disables routing) when the kendo.mobile.Application was created. The technique should still work when using browser history if you use a valid url fragment (same as would be created by Kendo for the pushstate/hashchange url).
This is a also way to cleanly subclass kendo.mobile.ui.View that works well - although you must still use data-role=view even though your subclass is a "different" component. Note that you can't just use you cant use your own subclassed component with its own name like role=myview to subclass a view because there are hard-coded checks specifically for data-role=view in the kendo codebase. Same if you wish to subclass: layout modalview drawer splitview page (amongst other hard-coded kendo ui component names - search kendo code for kendo.roleSelector - ugly). e.g.
MyView = kendo.mobile.ui.View.extend({
init: function(element, options) {
kendo.mobile.ui.View.prototype.init.apply(this, arguments);
...
var myView = new MyView('<div data-role=view>test</div>');
Why it works: The relevant function in the Kendo source code is _findViewElement which does element = this.container.children("[" + attr("url") + "='" + urlPath + "']"); to see if the view already exists for a url, before creating a new one. A unique init function is always required as it ends up being the constructor function.
If you want to subclass a modalview, you need to do something different due to the way kendo works:
var MyModalView = kendo.mobile.ui.ModalView.extend({
html: '<div data-role=modalview style="width:90%;display:none;">Foobar</div>',
init: function() {
kendo.mobile.ui.ModalView.prototype.init.apply(this, arguments);
}
});
function makeModalView() {
$(document.body).append($.parseHTML(MyModalView.prototype.html));
var roles = $.extend({}, kendo.mobile.ui.roles);
roles.modalview = MyModalView;
var modalView = kendo.initWidget($(element), {}, roles);
modalView.open();
return modalView;
}

I can't figure out how to programatically add a view into a layout or page.
I need to add views at runtime without using static xml declaration since i need to fetch them from an http requested object... . I didn't find useful informations in the docs.
Anyone knows how to do?
I think you meant to dynamically add some view / controls to the page rather than to navigate into another page.
If so, you just need to add some controls into one of the layouts in your page (only containers [=layouts] can have multiple children.
so, your code (viewmodel/page controller) would look something like:
var layout = page.getViewById("Mycontainer");
// create dynamic content
var label = new Label();
label.text = "dynamic";
// connect to live view
layout.addChild(label)
In addition to having a page included inside your app (normal); you download the xml, css, & js to another directory and then navigate to it by then doing something like page.navigate('downloaded/page-name');
you can also do
var factoryFunc = function () {
var label = new labelModule.Label();
label.text = "Hello, world!";
var page = new pagesModule.Page();
page.content = label;
return page;
};
topmost.navigate(factoryFunc);
https://docs.nativescript.org/navigation#navigate-with-factory-function
You should check out this thread on the {N} forum.
The question is about dynamically loading a page and module from a remote server. The (possible) solution is given in this thread.
how can add new control from controller
// create a simple Input field
var oInput1 = new sap.m.Text('input1');
oInput1.setText("Some Text ");
oInput1.setTooltip("This is a tooltip ");
// attach it to some element in the page
oInput1.placeAt("sample1");
in view I add holder
try to add text from controller but it not display on screen.
var oLayout = this.getView().byId("idholder");
oLayout.addContent(oInput1);
is Run-time add new control is not possible. we have always render control in view and then update it is this good practice we have to follow ?
The placeAt() method is normally only used to place a View or App into the HTML.
If you want to add a UI5 control on your view, you can do it this way from the controller:
this.getView().addContent(oInput1);
But most likely you won't add controls directly to the view, but rather inside a layout or something inside your view. In that case, do it like this:
var oLayout = this.getView().byId("idOfYourSpecificLayoutFrame");
oLayout.addContent(oInput1);
I need access to the ApplicationView from another view and I'm able to do so with App.__container__.lookup('view:application').
Is __container__ intended to be used this way?
Is there a better way to access instances of views?
(update)
My usecase:
My ApplicationView has a template with 2 columns.
The CSS is responsive so the size of the columns changes to accommodate the
width of the page.
I'm using Ember List View which requires height and width to be specified during initialization
I want to get the instance so I can access the DOM object to figure out its size
I can't use Ember.View.views because at that point, the ApplicationView has not been inserted into the DOM
Don't use that. One of the core developers said that whenever someone tries to use App.__container__, he would add another underscore.
If you really want to access an Ember.View intance use Ember.View.views['foo']. Where foo is the elementId of the view instance.
So if for example you want the App.ApplicationView instance:
App.ApplicationView = Ember.View.extend({
elementId: 'application'
});
// somewhere else in your code
var applicationViewInstance = Ember.View.views['application'];
Having said that, I never came across a situation where I needed to access view instances like that. If you can post your use case, I may be able to suggest alternative ways.
UPDATE: You want to access some properties of a view instance, from some other view instance (view height and width). You can pass those properties to the controller and let other controllers access them for using them in other views (source view -> source controller -> some other controller -> some other view):
App.ApplicationView = Ember.View.extend({
didInsertElement: function() {
var controller = this.get('controller'),
height = this.$().height(),
width = this.$().width();
controller.setProperties({
height: height,
width: width
});
}
});
App.SomeotherController = Ember.Controller.extend({
needs: ['application'],
applicationViewWidthBinding: 'controllers.application.width',
applicationViewHeightBinding: 'controllers.application.height'
});
App.SomeOtherView = Ember.View.extend({
// assuming its controller is an instance of App.SomeotherController
applicationViewWidthBinding: 'controller.applicationViewWidth',
applicationViewHeightBinding: 'controller.applicationViewHeight'
});
I am developing a mobile web app using Kendo UI Mobile. Whenever we make any AJAX calls, or our DataSources make them we call app.startLoading() to show the loading icon to the user. This works very well.
However, depending on the context in which the call is made we would like to change the text that is displayed along with the loading icon. I know you can define this when I create the kendo.mobile.Application instance. How can I change it afterwards?
The documentation does not suggest a way to do this, and a browse of the source code did not help me either. Is this really not possible?
EDIT: This is using Kendo UI Mobile v.2012.3.1114
I usually make a "utility" function to do this:
var _kendoApp = new kendo.mobile.Application(document.body, {});
var showLoading = function (message) {
_kendoApp.loading = "<h1>" + (message ? message : "Loading...") + "</h1>";
_kendoApp.showLoading();
};
I am also setting a default message of "Loading..." if one isn't passed in.
Edit:
I could have sworn that worked for me in a past app I did, but judging by thr source, I think you are right, my answer above shouldn't work. My best suggestion is to add a class to the message element so you can target it, and use jQuery to change the text.
var _kendoApp;
var showLoading = function (message) {
$(".loading-message").text(message ? message : "Loading...");
_kendoApp.showLoading();
};
_kendoApp = new kendo.mobile.Application(document.body, {
loading: '<h1 class="loading-message">Loading...</h1>'
});
Hi I am trying to make some changes to our implementation of CKEDITOR 3.6.2
by removing all but 2 options in the link target type dropdown that appears in the link dialog's target tab.
I tried to achieve this using the API but I am getting an error in the minified core ckeditor.js file in the dialog() method on this line X=S.lang.dir; where S is the editor.
The .lang property of the editor instance is undefined when doing CKEDITOR.dialog(editor, 'link'), when viewing debugging the "editor" object I don't see a lang object anywhere, so I'm not sure why this is missing? I didn't work on our original implementation but as far as I know we have only added 2 plugins and not changed the ckeditor core.
Here is my code:
for (var i in CKEDITOR.instances) {
var editor = CKEDITOR.instances[i];
var dialogObj = CKEDITOR.dialog(editor, 'link');
var linkDialogTargetField = dialogObj.getContentElement('target', 'linkTargetType');
// API didn't seem to have a more efficient approach than clearing all and re-adding the one we want
linkDialogTargetField.clear();
linkDialogTargetField.add('notSet', '<not set>');
linkDialogTargetField.add('_blank', 'New Window (_blank)');
}
I have managed to make my change without using the API properly by doing the below:
CKEDITOR.on('dialogDefinition', function (ev) {
// Take the dialog name and its definition from the event
// data.
var dialogName = ev.data.name;
var dialogDefinition = ev.data.definition;
// Check if the definition is from the dialog we're
// interested on (the "Link" dialog).
if (dialogName == 'link') {
// Get a reference to the "Link target" tab.
var targetTab = dialogDefinition.getContents('target');
var targetField = targetTab.get('linkTargetType');
// removing everything except the 1st (none set) & 3rd (new window) options from the dropdown
targetField['items'].splice(1, 2);
targetField['items'].splice(2, 3); // the array is reduced by splice, so we have to splice from [2] onwards not from [4]
}
});
but I don't like this approach, does anyone have any ideas? or other ways to achieve the same result using the API?
Using second approach and overwritten the dropdown items instead of splicing.
