In fact, it is no different from normal ajax. It mainly uses jquery’s serialize() method to serialize the form

In the middle I encountered some troubles because I am not familiar with the thinkphp5 framework. I have not had time to use 3.2.3 before. There are still some differences between the two versions.

One is that $_POST cannot be used, and the original ajax url can be used. The U method of the framework is gone. I looked specifically at the assistant function under think and found that it is url

The following is a random method for returning json data

public function test($mess,$id){
    if($mess == &#39;123&#39;){
      return json("ajax成功！".$mess."---".$id);
    }else{
      return json("你输出的是其他值：".$mess."---".$id);
    }
}

In addition, the regular parameter submission and The processing method is as follows:

Form submission and passing parameters:

<input type="hidden" name="project_name" value="$project_name"/>

Copy after login

Obtain

$project_name=input("post.project_name");

Copy after login

in the controller and jump to the passing parameters in php:

$this->success(&#39;新增项目成功&#39;,url("Version/index",array(&#39;project_name&#39;=>$project_name)));
die;
