Use timestamps to solve the problem of ie cache

In development tests, if you select ie, when editing a certain piece of data, you will find that the data inside is the same as before without editing. In this case, solving ie cache becomes a problem. My method is to add a timestamp after the request link to only avoid this problem.

The code copy is as follows:

var getTimestamp=new Date().getTime(); //Timestamp

var _url = "${pageContext.request.contextPath}/productData/addShow.do?productDataId="+value+"&timer=" + getTimestamp;
