`The function $(Window) is undefined` err in jquery - javascript

I used the Jquery 1.9.1 and used the code to fire when browser window will get closed as
My JSP will be ,
But this shows a red underline error like show in picture in eclipse.
I don't know why I am getting this error.Can any one help me to solve this.
Don't hesitate to ask any question.
Good answers are definitely appreciated.

Have you tried wrapping the code in doc ready handler:
$(function(){
//here unload and before unload
});
and you have to look that your jquery 1.9.1 is properly loading.
about error:
That is quite possible if you are using a CDN Hosted jQuery library. Try loading it locally and referencing it from there.

$ is an alias for jQuery. If $ is undefined it means the jQuery library has not been properly loaded. Be sure to include it in the page before attempting to use any jQuery methods.

jQuery undefined function in wordpress plugin which creates a fullCalendar

I am creating a plugin which uses the jQuery fullCalender.
The code appears to all be working fine however when the page fully loads and my shortcode populates its appropriate html and javascript I get the following error:
So from this I can gather that jQuery resolves ok - but somehow the calendar does not? Can somebody please help me! It may be because I am using OptimizePress which might be including its own copy of jQuery - and my plugin is also including a copy of jQuery and the calendar. But I dont know how to make sure i reference my own jQuery or make this work.
Thanks!
The answer was to use wp_register_script and wp_enqueue_script to add the script to my generated document

Bootstrap conflicting with jQuery lib

I´m using jQuery UI datePicker and jQuery UI toolTip and they work fine.
Then I also want to use the tagsManager from Bootstrap, but when I include the "bootstrap-tagmanager.js" and the "bootstrap.min.js" I start getting "TypeError: e is null" messages and neither the datePicker or the toolTip works.
(TypeError happens when click on the date-field for the datePicker).
Anyone has a work-around for this?
Are you including the javascript files in this order?
jquery.js
bootstrap.min.js
bootstrap-tagsmanager.js
look at: Does the ORDER of javascript files matter, when they are all combined into one file?
if you have conflit between jQuery file, use $.noConflict(); before your $(document).ready();
Make sure that your lib call is good. Call first the jQuery and add bootstrap lib after.
Maybe, jQuery.noConflict() will help you.

getting rid of Joomla warning errors in IE browser caused by mootools and jquery conflict

I am getting website developed here: http://extremeprodigy.com/projects/leelam36/
It shows an error in IE browser only in the status bar saying 'Done but with errors'. website is built with Joomla and mootools and jquery is being used. There seems to be a conflict but we are unable to resolve.
The current developer is having problem with mootools-compressed.js file and the erros description is as below:
TypeError:$(filter) || document).getElementsBySelector is not a function
Is there any way we can suppress or disable these warnings through code from showing in IE status bar?
Any help is much appreciated.

There is two solutions:
You find the conflict and resolve it.
You rely only on jQuery OR Mootools, not both.
Even if the less libraries you load the best it is, you probably can resolve your conflict by using jQuery() selector instead of $() everywhere you use jQuery. This should work. If you use jQuery plugins, make sure you replace the selector to jQuery() there too.
Hope it helps...
Use a try {} catch () {} statement.

replacing page content with .html(content) is not working

I have a weird problem in jQuery. The problem is that I can smoothly use $('#container').html(content) to replace the page content but to specific page. It is not working all around. Gives 'TypeError' message in console. Is there any probability that using SlickGrid can cause such error. Because error is thrown only in that pages where I have used SlickGrid.
Any suggestion would be highly appreciated.
It's hard to tell what's going on with your page, but my guess is that you may have a conflict with the $ between jQuery and SlickGrid. Look at the noConflict function in jQuery - it may help you out.
Call $.noConflict(); before SlickGrid's javascript <script> tag is added, and then refer to jQuery functions by using jQuery(selector) instead of $(selector).
Hope this helps!

Jquery plugin qTip - scrollLeft is not a function

I am trying to make use of qTip JQuery plugin.
I have tried to implement it but I get an error reported by firebug.
f(window).scrollLeft is not a function
[Break on this error] (function(f){f.fn.qtip=function(B,u){var...asses:{tooltip:"qtip-blue"}}}})(jQuery);
Please have a look at my setup.
What am i doing wrong?
I viewed source on your page and it looks like the jQuery version your using is older than what qTip requires.
http://craigsworks.com/projects/qtip/docs/#requirements
jQuery version 1.2.6 and above
http://174.132.101.73/~dandy/tester/jquery.js
jQuery 1.2.3
update and you should be good.
You should wait until the DOM is loaded before trying to attach qtip to it, so wrap your code in:
$(function() {
// your code here
});
Also check the version requirements as Samuel points out.
