javascript - Send request on unload and/or beforeunload doesn't work on mobile? -


i know issue has been answered on cannot make work on mobile browsers.

i need send request server when web page closed (tab or window closed).

here do:

    window.addeventlistener("unload",function(e) {         var pl = "bla=blabla";         var req = new xmlhttprequest();         req.open("post","http://myapi/myendpoint",false);         req.setrequestheader("content-type","application/x-www-form-urlencoded");         req.send(pl);     },false);      window.addeventlistener("beforeunload",function(e) {         var pl = "bla=blabla";         var req = new xmlhttprequest();         req.open("post","http://myapi/myendpoint",false);         req.setrequestheader("content-type","application/x-www-form-urlencoded");         req.send(pl);     },false);

this works fine on desktop (chrome , firefox) if page either refreshed or tab/window closed.

on mobile, works when page refreshed or if enter url. it doesn't work if close tab or program (chrome/safari...). far, i've tested with:

  • chrome on samsung s5 (android 4.4.2)
  • default browser on samsung s5 (android 4.4.2)
  • safari on ipad 3 (ios 8.0.2)
  • chrome on ipad 3 (ios 8.0.2)

on mobile, request never sent if close tab :(!

how can make work on mobile well? (ie when page tab or browser closed/shut down) ?
