Good day,

I have received the following error:

Uncaught Error: Syntax error, unrecognized expression: a[href*=#]:not([href=#]) for the library jquery-2.2.3.min.js:2

Below is the code:

$(document).ready(function() {
    $('.collapse').on('show.bs.collapse', function() {
        var id = $(this).attr('id');
        $('a[href="#' + id + '"]').closest('.panel-heading').addClass('active-faq');
        $('a[href="#' + id + '"] .panel-title span').html('<i class="glyphicon glyphicon-minus"></i>');
    });
    $('.collapse').on('hide.bs.collapse', function() {
        var id = $(this).attr('id');
        $('a[href="#' + id + '"]').closest('.panel-heading').removeClass('active-faq');
        $('a[href="#' + id + '"] .panel-title span').html('<i class="glyphicon glyphicon-plus"></i>');
    });
});

I am using the latest Jquery CDN

• None of the code you've shown produces that selector? – Bergi Commented May 4, 2016 at 17:04

The # is a special character and needs to be escaped like:

'a[href*=\\#]:not([href=\\#])'

Source: https://github./jquery/jquery/issues/2885

If I understand what you are trying to do you seem to have an extra # in your selector.

See this jsfiddle for a working example
