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 = $("").get(0).files !== undefined; feature.formdata = window.FormData !== undefined; var hasProp = !!$.fn.prop; // attr2 uses prop when it can but checks the return type for // an expected string. this accounts for the case where a form // contains inputs with names like "action" or "method"; in those // cases "prop" returns the element $.fn.attr2 = function() { if ( ! hasProp ) return this.attr.apply(this, arguments); var val = this.prop.apply(this, arguments); if ( ( val && val.jquery ) || typeof val === 'string' ) return val; return this.attr.apply(this, arguments); }; /** * 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 }; } else if ( options === undefined ) { options = {}; } method = options.type || this.attr2('method'); action = options.url || this.attr2('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 || '') ?
