你如何用JavaScript调用ASHX？ [英] How do you call an ASHX from JavaScript?

问题描述

我想调用ASHX文件并从JavaScript传递一些查询字符串变量，并将返回字符串转换为JavaScript中的字符串。我该怎么做？

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?

ASHX文件已编码为response.write一个基于查询字符串的字符串。

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

推荐答案

这样的东西？：

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;
