Question

I want to call an ASHX file and pass some query string variables from JavaScript and get the return string into a string in the JavaScript. How would I do this?

The ASHX file is already coded to response.write a string based on whatever the query strings are.

Answer 1

Something like this?:

function createXMLHttpRequest() {    try { return new XMLHttpRequest(); } catch(e) {}    try { return new ActiveXObject('Msxml2.XMLHTTP'); } catch (e) {}    try { return new ActiveXObject('Microsoft.XMLHTTP'); } catch (e) {}    alert('XMLHttpRequest not supported');    return null;  }  var xmlHttpReq= createXMLHttpRequest(); xmlHttpReq.open('GET', 'your.ashx?v1=1&v2=2&etc', false); xmlHttpReq.send(null); var yourJSString = xmlHttpReq.responseText;
