Question

So I have someone else’s old code that I am trying to restore. I am not too familiar with jQuery, but what does the @ operator specify?

The code is:

v_button_format = $('#' + v_form_id).find('input[@name=button_format]').val();
v_content_type = $('#' + v_form_id).find('input[@name=content_type]').val();

I am using jQuery 1.3 and it’s throwing an “uncaught exception: Syntax error, unrecognized expression: [@name=button_format]” error. Is there a compatibility issue?

Answer 1

This is an attribute selector.

The @ is an XPath-ism that is no longer used in jQuery.
In addition, newer versions of jQuery require the attribute value to be in quotes.

Therefore, you should write

$('#' + v_form_id).find('input[name="content_type"]').val();
