$. Ajax ({

Url: "ajax. php? Action = time_ajax"

});

/*********** Set the end time of participation **********/

Step 2: Set the cookie value in ajax

Case 'time _ ajax ': // defines the place where execution is performed per minute and a fixed timestamp. this is a fixed cookie that is not affected by refreshing other pages, depends on your situation.

Setcookie ("fasong_time", time (); // record a cookie timestamp

Exit ();

Break;

Functionfasong_email (){

$. Ajax ({

Url: "ajax. php? Action = fasong_zidong ",

Success: function (data ){

// Alert (data );
