How to trigger RaphaelJS Element.click() with jquery?

I am having problems with triggering RaphaelJS's Element.click() with jquery. What I am trying to do is simulating with jquery that the Element.node was clicked and what I am expecting is that Raphael will delegate the click treatment to the previously defined Element.click() method.
In some circumstances I will need to trigger Raphael's Elements event handlers with code somehow using my Element instance.
In order to simplify my problem, I created a plnkr with just the code that does not work for me. So here is the example:
http://plnkr.co/edit/AuSuq1RG6cWpqH2GEzcN?p=preview
What I expect of the code is that after $(r.getById("square").node).trigger("click"); (I have also tried using $(r.getById("square").node).click()) is executed, myRectangle.click(function() {...} will be called and the heading on the result page will be changed to "The rectangle was clicked!". As you can see this does not happen. However clicking on the shape is working fine.
Does anyone know what do I miss in this small piece of code? How to make such manipulation work?
Thanks!

After I worked around my initial problem so I can finish what I did start, now I found a helpful kinda-solution to the problem that might help others that come across my topic. What is written in the topic works and worth considering to be adopted as solution. It do look a bit hacky, but to be honest many things in JS do so. So here is the link, hope it can be helpful to someone someday :) - Triggering Raphael events externally

javascript detect ios7 ipad

following the code from this question, I'm trying to add a class to html for handling iPad landscape layout issues.
But the JS to detect iPad iOS7 doesn't seem to work anymore:
if (navigator.userAgent.match(/iPad;.*CPU.*OS 7_\d/i)) {
$('html').addClass('ipad ios7');
}
I tried it on an iPad4 iOS7.
Can anyone confirm that the detection code is working for them?
EDIT: thanks to Waki's test page, we can be sure it is working.
And going through my 800 lines of app code again thoroughly, I found that I called my function that includes the code for the check from within document.ready but the function itself was placed outside of document.ready and therefore was not called. Really stupid mistake. I apologize to all who wasted their time on reading this.

are included jQuery library for use $('html') ? Because this regex is working.

What's the general solution to "typeerror object doesn't support this property or method" on IE8?

I saw several specific questions about this problem - getting typeerror object doesn't support this property or method in IE8, each with its specific answer.
Suppose I have a large website with lots of code ... I don't know what specific snippet is causing this error.
Is there a general method to debug this? I've tried with the IE Developer Tools, and it doesn't break on error. Is this caused by incorrect javascript syntax? Should I try something like js lint?
What's the correct, general way to identify and deal with this problem?

OK, so I turned to the age old solution and started to delete massive chunks of code from my project until the problem was "fixed". This helped me locate the problematic file.
I then proceeded to delete function by function until I found this little snippet: str.trim(). A quick search turned this up.
Update: Actually, I just realized something ... the problem was just a normal exception, and passing it to alert() masked the details. If you let such exceptions go to the top, then whatever browser you use will display useful line information. So, the next time it happens to me, I'm going to look for a way to make the exceptions fly high outside of the top level function. The catch wasn't in my code, it was jQuery, so I'm still not quite sure how to do it.

Eclipse keeps jumping to the start of the document

I have been using Eclipse for some weeks now and I start getting used to it.
However, one thing really annoys me:
When editing JavaScript (I didn't try any other language yet), the editor window keeps jumping to the start of the document I am editing.
This mostly happens when the code currently contains syntax errors and mostly while / after deleting lines.
Especially constructs like { = and sometimes unterminated strings / comments seem to cause this problem.
When it happens, only the view scrolls to the top of the document - the cursor stays where it was before the "jump" occurred.
Anyone having an idea on how to fix this?

I believe the problem described above is related to this bug:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=318095
The work around is to disable the "Link with Editor" option from the Project Explorer. Which is to say make sure the icon with two arrows facing in opposite directions at the top of the file tree is not enabled. Disabling this option resolved the issue for me.

Looks like a problem with the implementation of the JavaScript editor. Most probably the jump occurs when the JavaScript-Parser is not able to parse your document and throws an exception. You might consider to report a bug to the eclipse project (maybe there is already such a report?).
As a workaround you might consider to adapt your way of typing the code a bit. Try to write the code in a way that does not confuse the parser (for example it might help to immediately close a newly created comment and THEN write the content instead of open the comment, write the content and finally close the commend). Same for strings, blocks ...

I am having the same problem. I had this line of code in my file and I could consistently reproduce the issue:
$.preload(preloadImages
, {
base:assetsUrl+'b/images/',
ext:'.png'
});
I changed it to the following and I no longer have the problem.
$.preload(preloadImages, {
base:assetsUrl+'b/images/',
ext:'.png'
});

I get this Phenomenon, when i'm editing in a Java-Class while still residing in a Debug-Process. The Debugger recognises the Change and reevaluates the Code and jumps back in order to be able to reexecute only the changed Code.

Hii i got solution goto
Window->Preferences->search autosave
and disble it and hit apply and close button.
this worked for me !

How viable is ie7-js by Dean Edwards?

I just found out about ie7-js ;
IE7 is a JavaScript library to make
Microsoft Internet Explorer behave
like a standards-compliant browser. It
fixes many HTML and CSS issues and
makes transparent PNG work correctly
under IE5 and IE6.
http://code.google.com/p/ie7-js/
It looks like it's really good, but is it really working (the current issue list looks quite scary)? Have you already worked using this with success?
Another question is how slow the script will make the website in IE ?

In static pages it works pretty well. If you designed a couple of static html pages using modern browsers and standards and want it to be shown correctly in IE6 and 7 this script is gonna help you.
But, and it's a big but, if you add a little javascript to the recipe, this method shows its weaknesses. Anything added later to them DOM or any event triggered afterwards will NOT be affected by this script.
That's it. my one line recommendation is if you have simple and light pages use it. otherwise try solve your problems by looking at the roots!

I think the best answer is: try it on your website and see if it works for your particular code. If it works, and doesn't impact the speed, great, you're done. If it doesn't work, then you're going to have to spend the time to make your site work in IE.
