I need get the id of my dynamic created element inside a div.
I'm looking for a way to get it's id by clicking it.
Example:
$("#div").on("click", '*', function () {
alert($(this).id);
});
The element can be an image, link, button, etc...
I need to dynamic bind click to it, and get the id when gets clicked.
I use append to add sub elements to div.
$("#div").append(element);
Elements are right shown, but i can't retrive the ids.
Is there anyway to get it?
Example in jsfiddle:
http://jsfiddle.net/StTvn
http://jsfiddle.net/StTvn/2/
changed the listener selector and it works
$("#myDiv").on("click", "*", function () {
txt = $(this).attr('id');
alert(txt);
});
as a side note, id that start with a number are not valid html - you might want to change the way you generate them like this:
el.id= "img" + i.toString();

I have two editors on the screen, one read-only. What I want to do is allow the user to select content from the read-only editor and paste it into the current position of the other by clicking a button. (the logic may manipulate the text which is one reason I don't want to use the system's clipboard.)
So far I have the function that is able to paste the text like as follows. (I am using the Angular wrapper which explains the presence of the CKEditorComponent reference.
doPaste(pasteEvent: PasteEvent, editorComponent: CKEditorComponent) {
const editor = editorComponent.editorInstance;
editor.model.change(writer => {
writer.insertText(pasteEvent.text, editor.model.document.selection.getFirstPosition() );
});
}
What I can't find from the documentation is how to extract the selected text. What I have so far is:
clickPasteSelectedPlain(editorComponent: CKEditorComponent) {
const editor = editorComponent.editorInstance;
const selection = editor.model.document.selection;
console.log('clickPasteAll selection', selection);
console.log('clickPasteAll selectedcontent', editor.model.document.getSelectedContent);
}
The selection appears to change depending on what is selected in the editor's view. The getSelectedContent function is undefined. How do I get the content?
With a bit of poking around I figured out how to do this. I'll document it here on the chance that it will help someone down the road avoid the process of discovery that I went through.
On the source document I have a ckeditor element like this:
<div *ngIf="document">
<ckeditor #ckEditor
[editor]="Editor" [config]="ckconfig" [disabled]="true"
[(ngModel)]="document.text"></ckeditor>
<button mat-flat-button (click)="clickPasteSelectedPlain(ckEditor)">Paste Selected Text Plain</button>
</div>
In the component the function called on the click event is like this:
#Output() paste = new EventEmitter<PasteEvent>();
...
clickPasteSelectedPlain(editorComponent: CKEditorComponent) {
const editor = editorComponent.editorInstance;
this.paste.emit({
content: editor.model.getSelectedContent(editor.model.document.selection),
obj: this.document,
quote: false
});
}
The PasteEvent is defined as an exported interface which I will omit here to save space. The content key will refer to a DocumentFragment.
Note that I am passing the CKEditorComponent as a parameter. You could also access it via an Angular #ViewChild declaration but note that my ckeditor is inside an *ngIf structure. I think that works well in Angular 6 but in the past I have had difficulty with #ViewChild references when the target was conditionally in the DOM. This method always works but use whatever method you want.
The event fired by the emit is processed with a method that looks like this:
doPaste(pasteEvent: PasteEvent, editorComponent: CKEditorComponent) {
const editor = editorComponent.editorInstance;
editor.model.insertContent(pasteEvent.content);
}
Because the content is a DocumentFragment the paste operation will include all formatting and text attributes contained in the selected source. But that's all there is to it.
I've binded the same function to all elements that I want(let's say View and Label).
In this onClick handler function I want to get the element which was clicked and increase its 'top' by 1.
Please tell me if you know how to do that, I can't find an answer yet.
My global click handler function:
function increaseElementTop(e) {
// Here we should increase element's top position.
Ti.API.info(JSON.stringify(e));
}
Thanks, any help is appreciated.
Get the e.source attribute from the Event e. Then use the setTop() method.
if (e.source == $.yourLabel) {
$.yourLabel.setTop($.yourLabel.getTop() + 1)
}
UPDATE: Regarding your comment: I thought it would only be used for two elements. A universal approach would be something like this:
e.source.setTop(e.source.getTop() + 1);
Unfortunately I have no machine available to test the code but I will do so later (Tuesday I guess). Just try it and let your programm print the e.source variable. If this does not work you can also try to use e.source.getId().
function increaseElementTop(e) {
var theUIElement = e.source;
theUIElement.top = theUIElement.top + 1;
}
Add the event listener to each of your UIElements, and this will get the element you click on & modify the top.
I have a custom menubutton in my tinyMCE editor that uses specific HTML elements elsewhere on the page as the menu items. I use a jQuery selector to get the list of elements and then add one each as a menu item:
c.onRenderMenu.add(function(c,m) {
m.add({ title: 'Pick One:', 'class': 'mceMenuItemTitle' }).setDisabled(1);
$('span[data-menuitem]').each(function() {
var val = $(this).html();
m.add({
title: $(this).attr("data-menuitem"),
onclick: function () { tinyMCE.activeEditor.execCommand('mceInsertContent', false, val) }
});
});
});
My problem is that this only happens once when the button is first clicked and the menu is first rendered. The HTML elements on the current page will change occasionally based on user clicks and some AJAX, so I need this selector code to run each time the menu is rendered to make sure the menu is fully up-to-date. Is that possible?
Failing that, is it possible to dynamically update the control from the end of my AJAX call elsewhere in the page? I'm not sure how to access the menu item and to update it. Something using tinyMCE.activeEditor.controlManager...?
Thanks!
I found a solution to this problem, though I'm not sure it's the best path.
It doesn't look like I can make tinyMCE re-render the menu, so instead I've added some code at the end of my AJAX call: after it has updated the DOM then it manually updates the tinymce drop menu.
The menu object is accessible using:
tinyMCE.activeEditor.controlManager.get('editor_mybutton_menu')
where mybutton is the name of my custom control. My quick-and-dirty solution is to call removeAll() on this menu object (to remove all the current menu items) and then to re-execute my selector code to find the matching elements in the (new) DOM and to add the menu items back based on the new state.
It seems to work just fine, though tweaks & ideas are always welcome!
I have a TabContainer with different tabs (ContentPanes). I am loading each type dynamically when the user selects something from a tree. I would like to be able to run a certain JS function on the newly loaded ContentPane/Tab. So something in this form:
dojo.forEach(
dojo.query("select"),
function(selectTag) {
selectTag.disabled = true;
}
);
However, I only want to process this on the newly loaded ContentPane/Tab... so let's say given a ContentPane/Tab Dojo Object, how do I do a forEach/query on its content only?
Thanks
You can give dojo.query a second argument telling it in which DOM node to start looking. So if you have a ContentPane with id "fooTab", you can do:
dojo.forEach(dojo.query("select", "fooTab"),
function(selectTag) {
....
}
);
Now, technically, "fooTab" is the "dijit ID", but the dijit's/ContentPane's outermost DOM node will also have an id "fooTab". Perhaps not the kosher way, but it works.
I have a requirement where I need to create a dojox.layout.ContentPane programmatically.
function constructContentPane(methodToBeCalled){
var testCntPane=new dojox.layout.ContentPane({
href: "some url",
executeScripts: true,
cleanContent: true,
onDownloadEnd: methodToBeCalled
}).placeAt("testContentPaneId");
testCntPane.startup();
}
This places the content pane inside testContentPaneId and calls methodToBeCalled method once the content pane is created.
I have two questions.
How do I check if the content pane is already created or not? I tried to check using the code below
if(dijit.byId("testContentPaneId") == undefined) {
//then don't create again
}
But this did not work. Each time it creates the content pane with the id dojox_layout_ContentPane_0. The last digit gets incremented each time.
Is this the right way to pass the onComplete method as argument? This is how I invoke this
constructContentPane(thisMethodWillBeCalled);
Is there any better way to do this? How do I invoke that method? I tried using eval(methodToBeCalled), but that did not work.
When you use the placeAt() method then the widget will be placed as a child to the specified dom node. I think in your case you should pass the dom directly to the constructor of the content pane.
Try doing like this instead:
var testCntPane=new dojox.layout.ContentPane({
href:"some url",
executeScripts:true,
cleanContent:true,
onDownloadEnd:methodToBeCalled
}, "testContentPaneId");
This will also make sure that the id of the content pane is testContentPaneId
