1. Use Ajaxreturn instead of Echo
2, True and false to return the result as a string, which is "true", "false"
3, the result of the return through Ajax is a string , can not be directly judged by the IF, but should use = = to judge, otherwise always for if (response) has always been true, so the return of the existing

First you have to have a good understanding of the MVC model before you can use thinkphp correctly.
1, thinkphp logic is/controller/method,
Suppose your module name is index (it should look like this from your project directory)

  
   where($where)->find()){            $this->ajaxReturn(true);        }else{            $this->ajaxReturn(false);        }    }}

Then your post code should write this, the location should be in the Thinkphp view folder

$.post("/Login/verify",{loginEmail:loginEmail}, function(response){    ...}

Return results with Ajaxreturn

False and true replace with ' false ' and ' true ' try

$.post (URL, data, function, ' josn ')
