Jquery $.getjson in IE cache problem

At Work the home page implements Ztree Ztree data is the JSON object returned in the background

Because the tree is fixed, every time we refresh the tree

$.getjson URLs are the same problem I modified or added a tree node and then refreshed the trees IE has no change in other browsers are OK

It's got me tangled up.

and then we searched the Internet for data discovery Solutions.

Workaround:

Jquery's $.getjson request has a caching mechanism that takes the data from the page cache directly to the background when requesting the same URL, instead of requesting the background

So we're going to change a URL

This is our url var url = "Xxxx/xxx"

Here's a way to generate a random number

function Getrandomnum (Min,max) {   var Range = max-min;   var Rand = Math.random ();   Return (Min + math.round (Rand * Range));   

and change our URLs.

var i=getrandomnum (1,100);

url=url+ "&random=" +i;

And then put the URL in it to solve the problem.
