javascript - passing headers with ajax in jquery -


i have problem passing headers in ajax call on jquery.

$.ajax({     url: '/resources/ajax/customize.aspx?' + qs + '&nocache=' + math.random(),     contenttype: "application/json",     headers: values,     context: $this,     cache: false,     success: function(data) {           //do stuff here     } });

in cases, gets headers values right, doesn't headers value. made sure 'values' variable contains data. wondering there specific cases headers don't pass in ajax?

update: tried as:

 $.ajax({      url: '/resources/ajax/customize.aspx?' + qs + '&nocache=' + math.random(),      contenttype: "application/json",      beforesend: function(xhr) { xhr.setrequestheader('values',values); },      //headers: values,      context: $this,      cache: false,      success: function(data) {                   //do stuff here      }  });

and there no luck that.

update 2

figured out problem. there url variable line breaks in it, line breaks caused headers not passed.

i facing same issue. got rid of line breaks using jquery's(or in js otherwise) $.trim() method. in case knew \n\r won't part of value legally. has checked trim fix it.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
