Thinkphp learns and uses the verification code to inadvertently make a mistake. Thinkphp learns and uses the verification code. the error code is 1 $ (. verify_img ). click (function () {2 vartimenownewDate (). getTime (); 3 varurl {: U (indexloginverify)} t + time Thinkphp learn and use the-verification code to accidentally make a mistake

First look at the code:

1 $ (". verify_img"). click (function (){

2 var timenow = new Date (). getTime ();

3 var url = "{: U ('index/loginverify ')} & t =" + timenow;

4 alert (url );

5 $ (this). attr ("src", url)

6 });

$ (". Reloadverify"). click (function (){

Var timenow = new Date (). getTime ();

Var url = "{: U ('index/loginVerify ')}? T = "+ timenow;

$ ("# Image_d"). attr ("src", url)

});

What is the region of the above code? And. After comparison, we can see where the problem is. It is also valid to keep up with a random number after the question mark. Var url = "{: U ('index/loginVerify ')}? "+ Math. random ();

It is clear to write the question here.
