js调用CS里的方法有很多我用一种简单的方法如下
CS里
public string test()
{
return "Hello World";
}
public string test()
{
return "Hello World";
}
aspx 页面
<html xmlns="
<head runat="server">
<title>无标题页</title>
<mce:script type="text/javascript" ><!
var demo=function(){
var b= "<%=test() %>";
alert(b);
}
// ></mce:script>
</head>
<body>
<form id="form" runat="server">
<div>
<input type="button" id="id" onclick="demo()" value="JS调用CS" />
</div>
</form>
</body>
</html>
<html xmlns="
<head runat="server">
<title>无标题页</title>
<mce:script type="text/javascript" ><!
var demo=function(){
var b= "<%=test() %>";
alert(b);
}
// ></mce:script>
</head>
<body>
<form id="form" runat="server">
<div>
<input type="button" id="id" onclick="demo()" value="JS调用CS" />
</div>
</form>
</body>
</html>
上面的是不带参数的要是后台CS里方法带参数就要注意了
CS:
public string test(string a)
{
return a;
}
[csharp] view plaincopy
public string test(string a)
{
return a;
}
aspx:
<html xmlns="
<head runat="server">
<title>无标题页</title>
<mce:script type="text/javascript" ><!
var demo=function(){
var a="Hello World";
var b= <%=test("+a+") %>;//这里一定注意单引号和双引号的使用!!!!!
alert(b);
}
// ></mce:script>
</head>
<body>
<form id="form" runat="server">
<div>
<input type="button" id="id" onclick="demo()" value="JS调用CS" />
</div>
</form>
</body>
</html>
<html xmlns="
<head runat="server">
<title>无标题页</title>
<mce:script type="text/javascript" ><!
var demo=function(){
var a="Hello World";
var b= <%=test("+a+") %>;//这里一定注意单引号和双引号的使用!!!!!
alert(b);
}
// ></mce:script>
</head>
<body>
<form id="form" runat="server">
<div>
<input type="button" id="id" onclick="demo()" value="JS调用CS" />
</div>
</form>
</body>
</html>
带参数的调用<%=test("+a+") %> 一定要用单引号包起<%=%>里面再是双引号这点是关键否则
调用不成功！
