well i used joomla's ScriptMerge to merge all js files into one but now i get window.addEvent is not a function on squeeze box initialization,everything else is working fine except for this...i noticed that the squeeze box code is the only javascript block left in the head tag,all the other scripts are merged and moved to body...when i click a button that opens squeeze box it wont open of course,but when i click it again it opens normally...does anyone have an idea how to resolve this error?maybe it is because now the mootools core is being called in the merged js file but not in the head so the squeeze box code returns error because it doesnt have the mootools core?
There is your problem:
You are using async attribute on the script - async means the script will load and not holding the dom execution like the default behavior does(without async or defer).
so you try to call window.addEvent when you don't have mootools loaded to the page and this is why you get the error of undefined.
2 solutions for the problem:
remove the async attribute to force the script to hold until loaded and then continue executing the dom.
add to the script tag the onload event and execute the rest of your script there:
<script src="http://tereni.me/cache/plg_scriptmerge/975e10ecd911c8ca09713d1120c51a6d.js" async type="text/javascript" onload="onLoadScript();"></script>
and after it inside another script tag:
function onLoadScript(){
window.addEvent('domready',function(){
alert('dom is ready');
});
}

In my project, the Ckeditor is part of a webpage, which is coded using GWT. So the interface to CKeditor is using Java.
Whenever the webpage is displayed, the CKeditor will be passed a HTML via setData(), which the CKeditor is supposed to show.
The problem is: CKeditor sometimes won't show the HTML. Its content was just empty, although I am very sure the html had been passed to setData().
I had tried several approaches to solve this problem, but none would work.
My approach
Create a TextArea using DOM.createTextArea()
Call myEditor=CKEDITOR.replace(textArea, config) to initialize the CKeditor
call myEditor.setData(html) to set the content.
It was good and showed the content at the first time.
But after the webpage got hidden and shown again, I called myEditor.setData(html2) to show another html, but this time the CKeditor showed nothing.
First solution (did not work)
I changed the code to call myEditor.destroy() before the webpage was hidden, and call CKEDITOR.replace(textArea, config) again when the webpage was visible again, after that I called myEditor.setData(newHtml).
This time it worked in IE and FF, but not in Chrome and Edge, it kept showing the content of the first load time, instead of showing the new HTML.
Second solution (did not work)
I changed it to call CKEDITOR.inline(textArea, config) instead of CKEDITOR.replace(textArea, config) when the webpage was visible again, while the destroy() and setData() was still called in the same order. This time the CKeditor again didn't show anything from the second time.
Last attempt
My last approach was to not calling destroy(), but creating a new TextArea each time before showing CKeditor, and called CKEDITOR.replace(textArea, config) and setData(html). This seems to work well, but occasionally the CKeditor still showed empty content.
Could anyone please help me to solve this problem?
I am using CKeditor 4.5.8.
Finally I figured out the solution:
Before hiding the ckeditor, call editor.destroy(true), and delete editor. (Before this, I only called editor.destroy() [note: no 'true'], which didn't work well).
Here is the code:
if (editor) {
editor.destroy(true);
delete editor;
}
Use this java script code that is very simple and effective.Note editor1 is my textarea id
<script>
$(function () {
CKEDITOR.timestamp= new Date();
CKEDITOR.replace('editor1');
});
</script>
second way ! In controller ,when your query is fetch data from database then use this code after .success(function().
$http.get(url).success(function(){
CKEDITOR.replace('editor1');
});
I have javascript files defined in the <head> of both my layout decorator template and my individual pages which are decorated. When I update a thymeleaf fragment in one of my pages the javascript defined in the head of the parent page no longer works. Is there a standard way to 'refresh' these js files?
Thanks.
Additional clarification :
I have a form submitted by an ajax call which updates a table in the page. I have a Jquery onClick function targeting a button in the updated table. The javascript doesn't seem able to bind to the returned elements in the updated part of the page. I select by element class and can see that the selection works prior to the partial fragment render.
For me it is unclear what you mean by
javascript defined in the head of the parent page no longer works.
The page is created on the server. Normally it contains urls of the javascript files
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
In this case 'refreshing' the javascript files can happen only in the client.
Check the html of the page in the client.
Are the tags as expected ?
Are there tags for all expected javascript files ?
With the browser tools (for example Google Chrom developer tools ) check that all script files are actually loaded.
If this doesnt help, it could be that the order of the script tags has changed between the first and second load. This could cause a different behaviour of the javascript executed in the browser.
EDIT :
With the initial load you bind javascript callbacks to dom elements.
You do this directly or through Jquery or other libraries.
When a new dom element is loaded, it has no callbacks bound to it, even if it has the same id as a replaced dom element.
So after the load you have to bind your callbacks again.
If you bound them 'by hand', just bind it again.
If you are using a JQuery plugin, that made the bindings, look into the code or documentation, many of them have a function for that or you can call initialization again.
Once you added new content to the DOM you need to bind again the new content.
Let's say I have a button with some class, the event in binded to the class:
<button class="someclass">Button 1</button>
<script>
var something = function() {
// do something
};
$(".someclass").on("click", something);
</script>
If I add more buttons from the same class to the DOM, they will have not have the click event binded. So once you load the new content via ajax, also remove all binding and add again (you need to remove or you will have buttons with 2 events).
$(".someclass").off("click");
$(".someclass").on("click" , something);
I am trying to fetch data from a site by simulating events using CasperJS with phantomJS 1.7.0.
I am able to simulate normal click events and select events. But my code fails in following scenario:
When I click on button / anchor etc on remote page, the click on remote page initiates an AJAX call / JS call(depending on how that page is implemented by programmer.).
In case of JS call, my code works and I get changed data. But for clicks where is AJAX call is initiated, I do not get updated data.
For debugging, I tried to get the page source of the element container(before and after), but I see no change in code.
I tried to set wait time from 10 sec to 1 ms range, but that to does not reflect any changes in behavior.
Below is my piece of code for clicking. I am using an array of CSS Paths, which represents which element(s) to click.
/*Click on array of clickable elements using CSS Paths.*/
fn_click = function(){
casper.each(G_TAGS,function(casper, cssPath, count1)
{
casper.then ( function() {
casper.click(cssPath);
this.echo('DEBUG AFTER CLICKING -START HTML ');
//this.echo(this.getHTML("CONTAINER WHERE DETAILS CHANGE"));
this.echo('DEBUG AFTER CLICKING -START HTML');
casper.wait(5000, function()
{
casper.then(fn_getData);
}
);
});
});
};
UPDATE:
I tried to use remote-debug option from phantomJS, to debug above script.
It is not working. I am on windows. I will try to run remote debugging on Ubuntu as well.
Please help me. I would appreciate any help on this.
UPDATE:
Please have a look at following code as a sample.
https://gist.github.com/4441570
Content before click and after click are same.
I am clicking on sorting options provided under tag (votes / activity etc.).
I had the same problem today. I found this post, which put me in the direction of jQuery.
After some testing I found out that there was already a jQuery loaded on that webpage. (A pretty old version though)
Loading another jQuery on top of that broke any js calls made, so also the link that does an Ajax call.
To solve this I found http://api.jquery.com/jQuery.noConflict/
and I added the following to my code:
this.evaluate(function () { jq = $.noConflict(true) } );
Anything that was formerly assigned to $ will be restored that way. And the jQuery that you injected is now available under 'jq'.
Hope this helps you guys.
Kinda New to Jquery and hit an issue regarding returned HTML. I am using the .load() function to load HTML returned from a jsp file - its all working grand except the returned HTML doesnt seem to allow further Jquery functions to be called on it.
i have a click and toggle combination running for "#showgame" - this id is in the returned HTML but clicking on it does nothing when it should. Do i have to update anything to tell jquery that this id now exists on the page after load() call?
Regards,
Cormac
You need to use the live() function to bind the click event.
$("#myelement").live("click", function() { });
Live binds the event to current and future elements that match the selector.

After I load a page through a WebBrowser, and I click a link that fires an AJAX script, I need to detect when the AJAX java script finishes loading HTML changes into a div. Since no DocumentCompleted event is fired when the AJAX script is run, I don't know when it finish running. Is there a way I can attach an event to be raised after I know 100% that the javascript finished changing the div?
The project is in C#.
Thanks
I did something similar recently (using jQuery):
$('#mydiv').change(function(){
// do stuff
}
);
Granted, I also use jQuery to set the HTML of that div. I suppose one non-jQuery approach for you could be to set HTML through your own function, which in turn can fire an onchange event.
#New in town: From my experience that is not correct. I use this on multiple DIVs that never get focus in the first place, and it works well and consistently. The normal behavior is as you describe, and normally only applies to the INPUT and SELECT elements, but this is not the case with jQuery.
There is no event. You must patch the JavaScript callback that the browser runs when the reply for the AJAX request comes in. This will contains code like "div.innerHTML = ...". Just put your code below that.
