The Form Plugin API provides many useful methods that allow you to easily handle the data in the form and the form submission process.

Test environment: deployed to web project in Tomcat.

1. Introduce dependent js

<script src="jquery-1.3.1.js" type="text/javascript"></script>
<script src="jquery.form.js" type="text/javascript"></script>

Copy after login

2. Initialization callback function.

First, we initialize the form and give it a beforeSubmit callback function - this is a function used for validation.

$(document).ready(function() { 
$('#myForm').ajaxForm({ 
target:'#output1', // 用服务器返回的数据 更新 id为output1的内容.
beforeSubmit: validate // 提交前，验证
}); 
});

Copy after login

3. Verification rules

function validate(formData, jqForm, options) { 
// formdata是数组对象,每个对象拥有名称和值.
// 数据如下面的格式：
// [ 
// { name: username , value: usernameValue }, 
// { name: password , value: passwordValue } 
// ] 
for (var i=0; i < formData.length; i++) { 
if (!formData[i].value) { 
alert('用户名,地址和自我介绍都不能为空!'); 
return false; 
} 
} 
var queryString = $.param(formData); //组装数据
//alert(queryString); //类似 ： name=1&add=2 
return true; 
}

Copy after login
