Javascript代码刷新这种Captcha [英] Javascript Code To Refresh This Kind Of Captcha

问题描述

是HTML文档中的验证码部分，我无法找到类节。

 < img class =captcha border =0src =https://www.gametwist.com/web/Captcha-Image/？
 bc = 000000& fc = 188eae& h = 58& w = 258& fill = ffffffalt =验证码图像> 
  

解决方案

最简单的方法是添加一些随机或时间戳参数所以浏览器不得不提出新的请求，下载新的图像。例如：

  document.querySelector（'。captcha'）。src + ='& _ ='+ Date.now （）; 
  

这段代码会将新的GET参数附加到查询字符串，类似于& _ = 1420922523150 。

Guys i am looking for refreshing Captcha without refresh the page , and there is no refresh button ... is there anyway i can make this work out ?

this is the captcha part in the HTML document , i could'nt find the class section .

     <img class="captcha" border="0" src="https://www.gametwist.com/web/Captcha-Image/? 
     bc=000000&fc=188eae&h=58&w=258&fill=ffffff" alt="captcha image">

解决方案

The simplest way would be adding some random or timestamp parameter so that browser had to make new request, downloading new image. For example:

document.querySelector('.captcha').src += '&_=' + Date.now();

This code will append new GET parameter to query string similar to &_=1420922523150.
