Jquery.ajax ({}) requests do not respond on ie and return 0. Other browsers are normal.

use layui to develop the background management page, but the requests on ie8 do not seem to be sent, and the returns are all 0. why? we tried to introduce the js file of XDR, but to no avail, the background still can not get the data. Is there any solution

?

whether there is an error message.
whether the jquery version is too high to support ie8. Try a lower version
