如何调用一个ASP.Net Web服务的JavaScript [英] How to call an ASP.Net Web Service in javascript
问题描述
正如标题状态，我试图从JavaScript调用写在ASP.Net Web服务（同样的解决方案，但在Visual Studio中不同的项目）。由于我增加了在此之前调用它在VB.Net服务Web引用，我试图通过直接调用它来使用此引用。
在Default.aspx页的身体，我有这个code：
＆LT; ASP：的ScriptManager ID =ScriptManager1=服务器＆GT;
＆LT;服务及GT;
＆LT; ASP：服务引用路径=〜/ App_WebReferences /本地主机/ ServiceName.discomap将InlineScript =真/＆GT;
＆LT; /服务及GT;
＆LT; / ASP：ScriptManager的＆GT;
但在JavaScript中，我根本无法打电话给我服务。任何人都可以解释我怎么样？我愿意做这样的事情：
＆LT;脚本类型=文/ JavaScript的＆GT;
警报（ServiceName.HelloWorld（））
＆LT; / SCRIPT＆GT;
终于找到了我认为是做了正确的方式，它不需要jQuery的，也不要为HTT prequest或任何奇怪的解决方法。下面是相关的code：
＆LT;％@页面语言=VBAutoEventWireup =false的codeFILE =Default.aspx.vb继承=_默认％GT;！＆LT; DOCTYPE HTML PUBLIC - // W3C // DTD XHTML 1.0过渡// ENhttp://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd\">＆LT; HTML的xmlns =http://www.w3.org/1999/xhtml＆GT;
＆LT;头=服务器＆GT;
＆LT;脚本SRC =WebService.asmx / JS类型=文/ JavaScript的＆GT;＆LT; / SCRIPT＆GT;
＆LT;脚本类型=文/ JavaScript的＆GT;
回调函数（MSG）{
警报（MSG）;
}; 函数的HelloWorld（）{
WebService.HelloWorld（回调）;
};
＆LT; / SCRIPT＆GT;
＆LT;标题＆GT;＆LT; /标题＆GT;
＆LT; /头＆GT;
＆LT;身体GT;
＆LT; DIV ID =测试的onclick =的HelloWorld（）;＆GT;
点击这个
＆LT; / DIV＆GT; ＆LT;表ID =form1的=服务器＆GT;
＆LT; ASP：的ScriptManager ID =ScriptManager1=服务器＆GT;
＆LT;服务及GT;
＆LT; ASP：服务引用路径=〜/ WebService.asmx/＆GT;
＆LT; /服务及GT;
＆LT; / ASP：ScriptManager的＆GT;
＆LT; /表及GT;
＆LT; /身体GT;
＆LT; / HTML＆GT;
As the title states, I'm trying to call a web service written in ASP.Net (Same solution, but different project in visual studio) from javascript. Since I added the web reference for the service prior to this for calling it in VB.Net, I tried to use this reference by directly calling it.
In the body of the Default.aspx page, I have this code:
<asp:ScriptManager id="ScriptManager1" runat="server">
<Services>
<asp:ServiceReference Path="~/App_WebReferences/localhost/ServiceName.discomap" InlineScript="true" />
</Services>
</asp:ScriptManager>
but in javascript, I can't call my service at all. Could anyone explain me how? I'd want to do something like this:
<script type="text/javascript">
alert(ServiceName.HelloWorld())
</script>
Finally found what I think is the right way to do it, it doesn't need jQuery at all, nor httprequest or any weird workaround. Here's the related code:
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<script src="WebService.asmx/js" type="text/javascript"></script>
<script type="text/javascript">
function callback(msg) {
alert(msg);
};
function HelloWorld() {
WebService.HelloWorld(callback);
};
</script>
<title></title>
</head>
<body>
<div id="test" onclick="HelloWorld();">
click this
</div>
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server">
<Services>
<asp:ServiceReference Path="~/WebService.asmx" />
</Services>
</asp:ScriptManager>
</form>
</body>
</html>
