jQuery form plug-in's formDdata parameter verification form and submission after verification_jquery
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>
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
});
});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;
}4. Detailed code:
jQuery form插件的使用--用 formData 参数校验表单 <script src="jquery-1.3.1.js" type="text/javascript"></script> <script src="jquery.form.js" type="text/javascript"></script>Demo 5 :jQuery form插件的使用--用 formData 参数校验表单，验证后提交（简单验证）.
The above is the formDdata parameter verification form of the jQuery form plug-in that the editor shared with you and all the content submitted after verification. I hope it will be helpful to everyone.
