I'm trying to add a CSS property dynamically to a control.
I have a group of RadioButton. On selection of any one of the buttons, I want to make one layout visible.
Below are some of the snippets I tried, none of them seem to work!
Snippet-1
showhide: function(){
var fcid = sap.ui.getCore().byId("FC7");
fcid.visibility = "hidden";
}
Snippet-2
showhide: function(){
var fcid = sap.ui.getCore().byId("FC7");
jquery('#fcid').css("visibility","hidden");
}`
Snippet-3
showhide: function(){
var fcid = sap.ui.getCore().byId("FC7");
jquery('#fcid').hide();
}
You cannot use fcid.visibility = "hidden"; and expect it to behave like a DOM object; it's not, it's a Javascript class with getters, setters, events, aggregations, etc.
Therefore, you should use the control's properties instead: fcid.setVisible(true);
See the API docs for the correct signature of the control/layout properties
You can:
var fcid = ...byId("FC7");
fcid.setVisible(false);
Or
fcid.$().hide(); // or every other jquery method
Or
fcid.addStyleClass("hiddenObject");
Last one with Css-Class:
.hiddenObject { display:none; }

I am trying to set the title of my view dynamically with no success so far.
I am trying something like this:
<div data-role="view"
id="mt-details-view"
data-title="#= pageTitle #" <---- this one
data-layout="mt-main-layout"
data-init="X.details.onInit"
data-before-show="X.details.beforeShow"
data-show="X.details.onShow"
data-model="X.details.viewModel"
data-use-native-scrolling="true">
I tried using a function, tried setting a viewModel variable, tried passing the title from the view.params, tried also to set the title on the onShow function like that:
function onShow(e) {
X.debug.dbg2(e.view.id, "onShow");
viewModel.setViewParams(e.view.params);
e.view.title = e.view.params.pageTitle;
e.view.options.title = e.view.params.pageTitle;
fetchSomeDetails();
}
nothing works.
Enlighten me please!
Here is one approach you can try. After declaring your viewmodel, bind a function to its 'set' method. Within here, check whether the field being set is the page title property on the viewmodel. If it is, find the dom element holding the title text and set its html to the value being 'set':
X.details.viewModel.bind("set", function(e) {
if (e.field == "pageTitle") {
$("#mt-details-view [data-role='view-title']").html(e.value);
}
})
Whenever that property is changed on the viewmodel, you will now see it reflected on the page. However there is still the issue of setting the value in the UI initially. You can do this in your onShow function which of course happens after the view is rendered and all the dom elements have been created:
function onShow(e) {
var temp = viewModel.pageTitle;
viewModel.set("pageTitle", null);
viewModel.set("pageTitle", temp);
}
That will force the 'set' method on the viewmodel to run and the UI should then update.
I'm using ember latest and jquery.ui's Draggable and Droppable. I am also using some mixins that a talented ember person created to make a Draggable and Droppable view in ember. Here's the fiddle:
http://jsfiddle.net/inconduit/6n49N/7/
I need to attach the view's content to the drag event so that I can access it in the drop event. With straight up jquery, I know you'd do $(..).draggable({ .. }).data("myData","some data here"); but I don't know how to reference the view's content in this ember implementation.
Here's a snippet from App.Draggable in the fiddle:
App.Draggable = JQ.Draggable.extend({
appendTo: 'body',
helper: function() {
$(this).data("myData","this is where actual data would go");
JQ.Draggable extends Ember.View. Inside the helper() function, 'this' refers to the actual DOM element, I don't know how to refer to the View's variables. I want to pass the view's content so that it can be retrieved here:
App.Droppable = JQ.Droppable.extend({
drop: function(event,ui) {
alert('Dropped! ' + $(ui.draggable).data("myData"));
The template for the draggable looks like this:
{{#view App.Draggable contentBinding="App.anObject"}}Drag me{{/view}}
and I would like to pass that content. Please have a look at the fiddle, the pertinent functions are defined at the bottom of the javascript.
answering my own question here.
i attached the data in the didInsertElement callback as follows:
App.DraggableDataView = App.Draggable.extend({
didInsertElement: function() {
this._super();
var element = this.get('element');
$(element).data('myData',this.get('content'));
},
});
I'm trying to start a jquery ui resizable instance, but using a selector added to the DOM by jquery itself. This is a basic example of my script:
HTML:
<div class='lyr'></div>
jQuery:
// Add class
$('lyr').addClass('fixed');
// Resizable
$('.fixed').resizable({
aspectRatio: true,
handles: 'all'
});
I've thought about using something along the lines of live() or bind() but I have no event to bind to. Any help appreciated.
I have used the LiveQuery plugin - http://brandonaaron.net/code/livequery/docs in the past to be able to target elements added to the dom, like in your case.
If I've got this right, you want anything on the page which has the class "fixed" to be resizable, even if the class is added after the page has loaded? You're right that live, bind and delegate won't help here.
I can think of two possibilities, neither lovely.
First, set up a live "mouseenter" event which will make the element resizable if it wasn't before:
$(body).delegate(".fixed", "mouseenter", function(ev) {
var target = $(ev.target);
if (target.data("resizable")) return;
target.resizable({
aspectRatio: true,
handles: 'all'
});
})
This gets us round the problem of having no event to bind to.
Alternatively, you could monkeypatch jQuery.fn.addClass:
var classRe = new RegExp(c + className + \b);
._addClass = jQuery.fn.addClass;
jQuery.fn.addClass = function(className) {
if (classRe.test(classname)) {
if (this.data("resizable")) return;
this.resizable({
aspectRatio: true,
handles: 'all'
});
}
jQuery.fn._addClass.apply(this, arguments);
}
Of course this will only work if the class is added through the addClass method.
Also in your example,
$('lyr').addClass('fixed');
Should probably be:
$('.lyr').addClass('fixed');
I have some troubles with jQuery.
I have a set of Divs with .square classes. Only one of them is supposed to have an .active class. This .active class may be activated/de-activated onClick.
Here is my code :
jQuery().ready(function() {
$(".square").not(".active").click(function() {
//initialize
$('.square').removeClass('active');
//activation
$(this).addClass('active');
// some action here...
});
$('.square.active').click(function() {
$(this).removeClass('active');
});
});
My problem is that the first function si called, even if I click on an active .square, as if the selector was not working. In fact, this seems to be due to the addClass('active') line...
Would you have an idea how to fix this ?
Thanks
Just to give something different from the other answers. Lonesomeday is correct in saying the function is bound to whatever they are at the start. This doesn't change.
The following code uses the live method of jQuery to keep on top of things. Live will always handle whatever the selector is referencing so it continually updates if you change your class. You can also dynamically add new divs with the square class and they will automatically have the handler too.
$(".square:not(.active)").live('click', function() {
$('.square').removeClass('active');
$(this).addClass('active');
});
$('.square.active').live('click', function() {
$(this).removeClass('active');
});
Example working: http://jsfiddle.net/jonathon/mxY3Y/
Note: I'm not saying this is how I would do it (depends exactly on your requirement) but it is just another way to look at things.
This is because the function is bound to elements that don't have the active class when you create them. You should bind to all .square elements and take differing actions depending on whether the element has the class active:
$(document).ready(function(){
$('.square').click(function(){
var clicked = $(this);
if (clicked.hasClass('active')) {
clicked.removeClass('active');
} else {
$('.square').removeClass('active');
clicked.addClass('active');
}
});
});
I have a CheckBox with a handler attached to the select event. In this function is the code to dynamically populate/ display few fields. If I come on the screen and the data brings in a value which makes the checkbox selected already, then those fields are not displayed (because they become visible only when I select the checkbox).
I want to ensure that if the CheckBox is auto selected, still I should be able to process the logic in the function, which has oEvent as an input parameter. But the issue is that if I call this function from another method, that function does not work as it has many statements like oEvent().getSource() which I do not pass.
Controller.js
onCheckBoxSelect: function(oEvent) {
var cells = sap.ui.getCore().byId("cell");
controlCell.destroyContent();
vc.abc();
var material= sap.ui.getCore().byId("abc");
var isSelected = oEvent.getParameters("selected").selected;
if (isSelected) {
// ...
}
},
someFunction : function(){
if(true){
// want to call onCheckBoxSelect here
}
// ...
},
If you assign an ID to your checkbox, you can get the checkbox in any function you want as long as it is known in the view. By doing that you won't need the oEvent which is only available when an event on the checkbox is executed.
Example:
var cb = this.byId('checkboxId');
if(cb.getProperty('selected')) {
// execute code
} else {
// do something else
}
Decouple the handler body into a separate function so that other functions can call the decoupled function with the right arguments. For example:
Controller
onCheckBoxSelect: function(oEvent) {
const bSelected = oEvent.getParameter("selected");
this.doIt(bSelected); // Instead of "doing it" all here
},
someFunction: function(){
if (/*Something truthy*/) {
const checkBox = this.byId("myCheckBox");
const bSelected = checkBox.getSelected();
doIt(bSelected); // passing the same argument as in onCheckBoxSelect
}
// ...
},
doIt: function(bSelected) { // decoupled from onCheckBoxSelect
// ...
if (bSelected) {
// ...
}
},
View
<CheckBox id="myCheckBox"
select=".onCheckBoxSelect"
/>
Or since 1.56:
<CheckBox id="myCheckBox"
select=".doIt(${$parameters>/selected})"
/>
Docu: Handling Events in XML Views
By that, you can have a pure, decoupled function that can be called from anywhere.
I would suggest a different approach. Use the same property that you have used in your checkbox binding, to determine the visibility of the other fields, i.e. bind the visible property of each relevant field to that property in your model.
If there is additional post-processing required in populating the fields, you can either use expression binding or custom formatter for field-specific processing, or model binding events if you need to do a bit more "staging" work (in which case you would probably store the resultant data in a client model and bind to that for populating your fields).
