I am having issues making a javascript work. Basically i just use this script for different web parts which have the .q1table class to insert some other classes.

I am getting an error uncaught type error Property $ of object[object window] is not a function.This works fine when the page is in normal mode but in edit mode it throws error.

can some one please tell me what am i doing wrong here.

 jQuery('.q1Table tr').each(function (index) {

   var $wp = $(this).find('tr:first');  ---this line throws the error

   var $1TR = $wp.closest('tr');

I can't garantee if this (only) solves your problem. At least this can be a tip for using jQuery within SharePoint.

One should avoid using $ for jQuery in SharePoint. It can conflict with SharePoint's other javascript objects like cmssitemanager as described in my blog post $ in cmssitemanager.js conflicts with $ in jQuery

I often disable $ for jQuery by running:


Then only jQuery is available and $ doesn't conflict with SharePoint's $ objects. Hopefully, Microsoft won't use $ in their javascript code in the future.

    I also think this could help. I usually replace every $ with jQuery, for example jQuery(this).find('tr') instead of $(this).find('tr') Aug 1, 2012 at 6:47

SharePoint has very specific instances where the $ namespace collides with one of SharePoint's JavaScript includes when you are in Page Edit mode and also in rare instances of FAST Search.

jQuery.noConflict(); is a great option, but you have to be careful when using it - if any other web parts are using jQuery and they reference the $(...) instead of jQuery(...), their code will stop functioning.

I have an article on my blog that deals with the jQuery.noConflict().

Another fun and safe way I've been using jQuery is by utilizing your own namespace:

$mine = jQuery.noConflict();

Hope this helps!


If you want to use only first TR from your table. You can try other approach in JQuery which may be useful, like:

$(".q1Table tr:nth-child(1)").addClass("TitleBar");

$(".q1Table tr:nth-child(1)").removeClass('ms-Header');
