It seems that you are attempting to make a model dialog using some third-party jQuery plugin, but you foget to make a reference to that plugin's javascript file.

To confirm this, i wonder which line does the exception occurs on? Is it on the line of first line of your ready callback?

$("#deleteModal").modal("hide");

If so, please check your script reference. Just add a <script> tag with a src to that file before your script block.

Update:

As you ments, the exception does not occurs on that line. So you may use a debugger(such as Chrome developer tools) to find out which function-call fails. You can set the debugger to pause the excution on exceptions. In chrome developer tools, you can switch to Source tab and click the last icon on right-top of the side-bar on the right to enable this feature.

Had the same error on standalone plain old HTML+Javascript page.

Apparently caused by socket.io.js which script tag was initially placed after jquery and bootstrap.js script tags.

Moving socket.io.js script tag before jquery and bootstrap resolved the issue for me.
