I was just learning and used ajaxSubmit. I hesitated because I had never been exposed to this before, so I was confused at first. Finally, I solved this problem by searching for information. I was very excited and uploaded the page without refreshing. Picture, I would like to give a sentence to friends who read my blog: "The mountain is high, and hard work will determine success!"

Let me summarize ajaxSubmit below:

1.Introduce jQuery;

2.Download the jQuery Form plug-in online;

Here is an introduction to the form plug-in, because people who are just starting to do front-end work may not understand it. , jQuery Form plug-in is an excellent Ajax form plug-in, which can easily and non-invasively upgrade HTML forms to support Ajax.

jQuery Form has two core methods - ajaxForm() and ajaxSubmit(), which combine functions from controlling form elements to deciding how to manage the submission process.

In addition, the plug-in also includes other methods:

formToArray(), formSerialize(), fieldSerialize(), fieldValue(), clearForm(), clearFields() and resetForm ()wait.

Core methods: ajaxForm() and ajaxSubmit()

3. Let’s talk about usage first. Both ajaxForm and ajaxSubmit can receive 0 or 1 parameter, which can be a variable, An object or callback function. This object mainly has the following parameters:

var object= {
      url:url,　　　　　　//form提交数据的地址
　　　　　　 type:type,　　　 //form提交的方式(method:post/get)
　　　　　　 target:target,　　//服务器返回的响应数据显示的元素(Id)号
      beforeSerialize:function(){} //序列化提交数据之前的回调函数
　　　　　　 beforeSubmit:function(){},　　//提交前执行的回调函数
　　　　　　 success:function(){},　　　　 //提交成功后执行的回调函数
      error:function(){},    //提交失败执行的函数
　　　　　　 dataType:null,　　　　　　　//服务器返回数据类型
　　　　　　 clearForm:true,　　　　　　 //提交成功后是否清空表单中的字段值
　　　　　　 restForm:true,　　　　　　 //提交成功后是否重置表单中的字段值，即恢复到页面加载时的状态
　　　　　　 timeout:6000 　　　　　 　 //设置请求时间，超过该时间后，自动退出请求，单位(毫秒)。
