JQuery-Form中的AjaxForm和AjaxSubmit的区别
作者:钱途无梁 来源:博客园 发布时间:2009-09-14 21:26
JQuery中的AjaxForm和AjaxSubmit使用差不多功能也差不多。很容易误解。
按照作者的解释:
AjaxForm
ajaxForm不能提交表单。在document的ready函数中,使用ajaxForm来为AJAX提交表单进行准备。提交动作必须由submit开始
ajaxSubmit
马上由AJAX来提交表单。你可以在任何情况下进行该项提交。

var options = {
target: '#output1', // target element(s) to be updated with rver respon
beforeSubmit: showRequest, // pre-submit callback
invalid addresssuccess: showRespon // post-submit callback
// other available options:
//url: url // override for form's 'action' attribute
//type: type // 'get' or 'post', override for form's 'method' attribute
//dataType: null // 'xml', 'script', or 'json' (expected rver respon type)
//clearForm: true // clear all form fields after successful submit
//retForm: true // ret the form after successful submit
// $.ajax options can be ud here too, for example:

ajaxForm
The following code controls the HTML form beneath it. It us ajaxForm to bind the form and demonstrates how to u pre- and post-submit callbacks
// prepare the form when the DOM is ready
$(document).ready(function() {

// here we could return fal to prevent the form from being submitted;
// returning anything other than fal will allow the form submit to continue

// post-submit callback

ajaxSubmit
The following code controls the HTML form beneath it. It us ajaxSubmit to submit the form.
// prepare the form when the DOM is ready
$(document).ready(function() {
var options = {
target: '#output2', // target element(s) to be updated with rver respon

//clearForm: true // clear all form fields after successful submit
//retForm: true // ret the form after successful submit
// $.ajax options can be ud here too, for example:
//timeout: 3000
};
// bind to the form's submit event
$('#myForm2').submit(function() {
// inside event callbacks 'this' is the DOM element so we first
// wrap it in a jQuery object and then invoke ajaxSubmit
$(this).ajaxSubmit(options);
// !!! Important !!!
// always return fal to prevent standard browr submit and page navigation
