JQuery中的AjaxForm和AjaxSubmit
JQuery读书笔记--JQuery-Form中的AjaxForm和AjaxSubmit的区别

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。
option的参数
var options = {   
       target:        '#output1',   // target element(s) to be updated with server response   
       beforeSubmit:  showRequest,  // pre-submit callback   
       success:       showResponse  // 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 server response type)   
       //clearForm: true        // clear all form fields after successful submit   
       //resetForm: true        // reset the form after successful submit   
 
       // $.ajax options can be used here too, for example:   
       //timeout:   3000   
   };  

示例代码摘自：http://www.malsup.com/jquery/form/#code-samples
ajaxForm
The following code controls the HTML form beneath it. It uses ajaxForm to bind the form and demonstrates how to use pre- and post-submit callbacks
// prepare the form when the DOM is ready
$(document).ready(function() {
    var options = {
        target:        '#output1',   // target element(s) to be updated with server response
        beforeSubmit:  showRequest,  // pre-submit callback
        success:       showResponse  // 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 server response type)
        //clearForm: true        // clear all form fields after successful submit
        //resetForm: true        // reset the form after successful submit

        // $.ajax options can be used here too, for example:
