The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubt that "how to solve the cache problem that Ajax can not refresh data under IE9". Next, please follow the editor to study!

Use jQuery's getJSON to regularly get data from the background and refresh the interface. Using the following methods, there is no problem under Chrome,Firefox, but the data cannot be refreshed under IE9.

$.getJSON (webApp + "/ GetShowData.do?limit=" + limit,function (data) {/ / *}

The reason is that under IE9, if the Ajax request is the same as the previous request, the data will no longer be obtained from the browser, but directly from the local. Therefore, if you add a timestamp to the request, IE9 will consider it to be a different request, as follows:

GetJSON (webApp + "/ GetHccShowData.do?" + new Date (). GetTime () + "limit=" + Hcc.limit,function (data) {/ / *} at this point, the study on "how to solve the cache problem that Ajax can not refresh data under IE9" is over.
