These functions are mutually exclusive. Use ajaxSubmit if you want to bind your own submit handler to the form. For example, $(document).ready(function() { $('#myForm').on('submit', function(e) { e.preventDefault(); // <-- important $(this).ajaxSubmit({ target: '#output' }); }); }); Use ajaxForm when you want the plugin to manage all the event binding for you. For example, $(document).ready(function() { $('#myForm').ajaxForm({ target: '#output' }); }); You can also use ajaxForm with delegation (requires jQuery v1.7+), so the form does not have to exist when you invoke ajaxForm: $('#myForm').ajaxForm({ delegation: true, target: '#output' }); When using ajaxForm, the ajaxSubmit function will be invoked for you at the appropriate time. */ /** * Feature detection */ var feature = {}; feature.fileapi = $("").get(0).files !== undefined; feature.formdata = window.FormData !== undefined; /** * ajaxSubmit() provides a mechanism for immediately submitting * an HTML form using AJAX. */ $.fn.ajaxSubmit = function(options) { /*jshint scripturl:true */ // fast fail if nothing selected (http://dev.jquery.com/ticket/2752) if (!this.length) { log('ajaxSubmit: skipping submit process - no element selected'); return this; } var method, action, url, $form = this; if (typeof options == 'function') { options = { success: options }; } method = this.attr('method'); action = this.attr('action'); url = (typeof action === 'string') ? $.trim(action) : ''; url = url || window.location.href || ''; if (url) { // clean url (don't include hash vaue) url = (url.match(/^([^#]+)/)||[])[1]; } options = $.extend(true, { url: url, success: $.ajaxSettings.success, type: method || 'GET', iframeSrc: /^https/i.test(window.location.href || '') ?
