From the front-end code and then find the img tag, and then set the click event, one point, for once authentication code.
When clicked, acquired image src attribute, and then set an onclick event (is a function, in main.js in), and then set a request url = "imag -? Code imagecodeid =" + UUid (automatically generated using generateUUID function , inageuuid = generateUUID ()), then get to the img tag ($ ( ". get_pic_code"). attr ( "src", url)) (attr and prop the same). Finally, clear the cache, reload,
Finally disposed at a rear end view corresponding :( function receives the request, generates authentication code)
