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.
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;
