jQuery ajaxSubmit 实现ajax提交表单局部刷新

AJAX简介

AJAX = Asynchronous JavaScript and XML（异步的 JavaScript 和 XML）。

AJAX 不是新的编程语言，而是一种使用现有标准的新方法。

AJAX 是与服务器交换数据并更新部分网页的艺术，在不重新加载整个页面的情况下。

需要引入 ： jquery-form.js

使用说明：

Java代码

$(document).ready(function() { var options = { target: '#mydiv', // 需要刷新的区域 //beforeSubmit: showRequest, // 提交前调用的方法 //success: showResponse // 返回后笤俑的方法 // other available options: //url: url // 提交的URL, 默认使用FORM ACTION //type: type // 'get' or 'post', override for form's 'method' attribute //dataType: null // 'xml', 'script', or 'json' (expected server response type) //clearForm: true // 是否清空form //resetForm: true // 是否重置form // $.ajax options can be used here too, for example: //timeout: 3000 }; // 绑定FORM提交事件 $('#myForm').submit(function() { $(this).ajaxSubmit(options); // !!! Important !!! // always return false to prevent standard browser submit and page navigation return false; }); }); 

调用前后方法：

Java代码

// pre-submit callback function showRequest(formData, jqForm, options) { // formData is an array; here we use $.param to convert it to a string to display it // but the form plugin does this for you automatically when it submits the data var queryString = $.param(formData); // jqForm is a jQuery object encapsulating the form element. To access the // DOM element for the form do this: // var formElement = jqForm[0]; alert('About to submit: /n/n' + queryString); // here we could return false to prevent the form from being submitted; // returning anything other than false will allow the form submit to continue return true; } // post-submit callback function showResponse(responseText, statusText) { // for normal html responses, the first argument to the success callback // is the XMLHttpRequest object's responseText property // if the ajaxSubmit method was passed an Options Object with the dataType // property set to 'xml' then the first argument to the success callback // is the XMLHttpRequest object's responseXML property // if the ajaxSubmit method was passed an Options Object with the dataType // property set to 'json' then the first argument to the success callback // is the json data object returned by the server alert('status: ' + statusText + '/n/nresponseText: /n' + responseText + '/n/nThe output div should have already been updated with the responseText.'); } 

项目中可以写一个公用的方法：

Java代码

// 局部提交表单 function formSubmit(formId, divId, url) { $('#' + formId).submit(function() { $(this).ajaxSubmit( { target : '#' + divId, url : url, error : function() { alert('加载页面' + url + '时出错！') } }); return false; }); }
