Solution to the problem that the verification code does not refresh in IE but works normally in Google and other browsers_javascript skills

When I was doing the verification code today, I found that in IE, the verification code would not refresh, but other browsers such as Google had no problem, so I thought it might be a cache problem, because the default setting of IE is that if the access address does not change, it will not go there. Get but load the content in the cache

So the solution is to add a random parameter after the switching address of the verification code

For example:

Copy code The code is as follows:

<script> <br>//Change verification code<br>function changeimg(){ <br>/ * <br>math.random range is 0-1 <br>*999 becomes 0-999 <br> 3000 is 3000-3999 <br>*/ <br>var time=Math.round(Math.random() *999) 3000; <br>$('#captcha').attr('src','__APP__/Public/verify/time/' time); <br>} <br></script>
