1.向项目中添加Jscript文件
//script_1.js-----
function doClick1()
{
alert("OK1_wufeng");
}
//script_2.js-----
function doClick2()
{
alert("OK2");
}

2.解决方案资源管理器中，右键查看script_1.js和script_2.js的属性，把高级中的“生成操作”属性设置成“嵌入的资源”。

3.向AssemblyInfo.cs文件中添加如下行：(注意域名wf.ClientScriptResourceLabel)
[assembly: System.Web.UI.WebResource("wf.ClientScriptResourceLabel.script_1.js", "application/x-javascript")]
[assembly: System.Web.UI.WebResource("wf.ClientScriptResourceLabel.script_2.js", "application/x-javascript")]

4.向项目中添加一个类, 实例:
using System;
using System.Drawing;
using System.Web.UI;
using System.Web;
using System.Globalization;

namespace wf.ClientScriptResourceLabel
{
public class ClientScriptResourceLabel : System.Web.UI.WebControls.WebControl
{
//调用脚本资源
protected override void OnPreRender(EventArgs e)
{
if (this.Page != null)
{
this.Page.ClientScript.RegisterClientScriptResource(typeof(ClientScriptResourceLabel), "wf.ClientScriptResourceLabel.script_1.js");
this.Page.ClientScript.RegisterClientScriptResource(typeof(ClientScriptResourceLabel), "wf.ClientScriptResourceLabel.script_2.js");
}
base.OnPreRender(e);
}

/// <summary>
/// 呈现控件的方法RenderContents
/// </summary>
protected override void RenderContents(HtmlTextWriter output)
{
output.AddAttribute("id", "1");
output.AddAttribute("type", "checkbox");
output.AddAttribute("value", "测试1");
output.AddAttribute("onclick", "javascript:doClick1();");
output.RenderBeginTag(HtmlTextWriterTag.Input);
output.RenderEndTag();

output.AddAttribute("id", "2");
output.AddAttribute("type", "checkbox");
output.AddAttribute("value", "测试2");
output.AddAttribute("onclick", "javascript:doClick2();");
output.RenderBeginTag(HtmlTextWriterTag.Input);
output.RenderEndTag();

base.RenderContents(output);
}
}
}
