Question

I have a div that I am trying to run a regular expression on

<div class="module-header-content module-default">

I am using this replace operation that used to work,but now that I have added the module-header-content class it becomes problematic

replace(/module-\w+/gi, ' ');

I need a regular expression that removes all instances of module- except for module-header-content

Any help.

Thanks

The entire call:

        var $target = $(this).parent().parent().parent().parent();


        //// Removes all module-xxxx classes
        var classes = $target[0].className.replace(/module-\w+/gi, '');

Try this:

str = "module-header-content module-default module-default-foo module-default-foo-bar";
str.replace(/module(?!-header)(-\w+)*/gi, '');

It’ll get all classes except “module-header-content”.
