问题 I want to set a theme preference cookie for a link function. Here's how the HTML of the element looks like: <li class="menu-item theme-item"> <a href="javascript:void()" class="btn" aria-pressed="false">Theme Toggle</a> </li> And here's how the jQuery function for this element is set: $('.theme-item .btn').on('click', function(e) { e.preventDefault(); $(this).attr('aria-pressed', $(this).attr('aria-pressed') === 'false' ? 'true' : 'false'); $('html').attr('data-theme', $('html').attr('data

问题 I'm using the jQuery plugin "jQuery-File-Upload" to manage a form I have. I've tried searching for my problem on google but nothing so far. The problem is that this form allows an optional field for file upload. When I insert a file it all goes ok, but when I decide to not include a file the plugin script won't even run. Now I know this is a plugin specifically to upload files, nevertheless it becomes rather inconvenient if we have to duplicate code just to provide an alternative AJAX call

问题 I have a form that is being generated by legacy back-end code that, for a variety of reasons, I can't change. The form is straightforward HTML: <form action="#" id="theForm" onsubmit="return check_theForm(); method="post"> <!-- fields go here --> </form> On submission the onsubmit parameter fires to verify that all compulsory field have been filled in, using the check_theform() function which contains "plain vanilla" javascript (i.e. no jQuery code).
