从Java脚本文件调用Web服务 [英] Calling Web Service from a Javascript file

问题描述

我正在尝试从一个简单的javascript文件调用Web服务的Web方法.该javascript文件可以添加到任何其他项目中，并且需要与数据库进行对话并获取一些数据.
我不想添加webservice.htc文件或具有Web参考，因为这将完全使上述目标无效.
我只想知道，有没有一种更好，更直接的方法可以通过JavaScript调用ASP.Net 3.5 Web服务?
如果是这样，请告诉我

谢谢，
拉姆

Hi,

I am trying to call a web method of a web service from a simple javascript file. This javascript file could be added to any other project and it needs to talk to database and fetch some data.
I do not want to add a webservice.htc file or have a web reference as this will totally nullify the above goal.
All I would like to know is, is there a better and straight forward way to call a ASP.Net 3.5 web service from a javascript?
If so, please let me know

Thanks,
Raam

推荐答案

您可以通过ajax调用Web服务.
示例:

you can call web service by ajax.
Example:

var J = jQuery.noConflict();

function PreLoadMouseOverImages() {
    var i = 0;
    J.ajax({
        type: "GET",
        url: "webservice1.ashx",
        success: function (msg) {

            //msg is the response data
            // you can do your work here.
        }
    });
}

搜寻"javascript xmlhttp".

googling for "javascript xmlhttp".
it might help you.

XMLHttpRequest()在我的域内有效.如果我尝试访问其他域URL，请求不会继续吗?
请让我知道

XMLHttpRequest() works within my domain. If I try to access a different domain URL, the request isn''t going?
Please let me know
