jQuery ajax表单提交实现局部刷新

jQuery ajaxSubmit可以实现AJAX提交表单 局部刷新页面DIV  （可以实现刷新JSP TABLE 哦！）

 

需要引入 ： jquery-form.js

 

 

使用说明：

$(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：

// 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：

// 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;
   });
}

 

 

=====================================================================

事例 刷新TABLE：

 

1.把TABLE单独放一个JSP，主页面 include TABLE页面。

 

2.主页面：

 

window.οnlοad=function (){
            //AJAX 提交FORM刷新TABLE
            $('#queryForm').submit(function() {
                $(this).ajaxSubmit( {
                    target : '#table1'
                });
             return false;
       });
}

 

点击查询按钮  提交FORM。

 

3.JAVA：FORM提交调用的方法和 普通的ACTION写法一样， STRUTS里配置该ACTION跳转到  那个单独的TABLE JSP页面，返回成功后，就会看到刷新了TABLE。
