/** * Output Verification Code */Public Function getverify () {$VModle =new \think\verify ();        $VModle->codeset= ' 0123456789 ';        $VModle->length=4;    $VModle->entry (); }

The HTML in the page

<input type= "Text" name= "verify" placeholder= "Verification Code" class= "Form-control" style= "width:100px;float:left;" > 

Javacsript Instant Refresh
$ ("#verifyimg"). Click (function () {var verifyurl = "{: U (' public/getverify ', '", ')} ";            var time = new Date (). GetTime ();        $ (this). attr ({"src": verifyurl+ "/" +time}); });

Asynchronous validation is correct:
    /**     *  asynchronously verifies that the verification code is correct      *   @params  verify;     */    public function  Ajaxcheckverify () {        if (!is_post) {              $data [' Status '] = 0;         }        else{              $VModle =new \think\verify ();              $code  = trim (I (' verify '));              if (! $VModle->check ($code)) {                  $data [' Status '] = 0;                  $data [' Data '] =  $code;             }             else{//Validation Successful                 $ data[' status '] = 1;            }         }        echo json_ Encode ($data);     }
