[原创]JavaScript调用Button的服务器端事件

方法一：
在JS中使用button按钮的click方法

<script type="text/javascript">
function JSFun2()
{
document.getElementById("<%= btnTest4.ClientID %>").click();
}
</script>
方法二:
ClientScript.GetPostBackEventReference(btnTest2, "")
上面这行代码的返回值是一个string,"__doPostBack('btnTest2','')".

然后使用RegisterClientScriptBlock注册一下脚本.
string jscript = "function JSFun1(){" + ClientScript.GetPostBackEventReference(btnTest2, "") + "};";
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "", jscript, true);

C#
using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;

namespace GetPostBackEventReference_Test
{
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
this.btnTest1.OnClientClick = "JavaScript:JSFun1();return false;";
this.btnTest3.OnClientClick = "JavaScript:JSFun2();return false;";
}

string jscript = "function JSFun1(){" + ClientScript.GetPostBackEventReference(btnTest2, "") + "};";
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "", jscript, true);
}

protected void btnTest2_Click(object sender, EventArgs e)
{
Response.Write(DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss fffffff"));
}
}
}
