TP Big God help me to see, Verification code can not refresh,. Is there a problem with JS?

            Verification Code:
            
            
        

------to solve the idea----------------------
First make sure that home/index/verify_c this address can be normal brush one time to change a verification code

Second, will your address automatically convert random=2 to/RANDOM/2?

Do not see the IMG Click event onclick Code, does TP generate for you?
Please check the source code of the page in the Browse page

First check the URL of the load will be able to generate a normal code, and then you can detect whether the JS code will normally let IMG load the click event, and finally do a click Refresh.
