前臺js：

<script type="text/javascript">
    function alertClick() {
        mini.alert("資訊已提交！");
    }
</script>

 <input id="inputs" type="button" value="提交" runat="server" onserverclick="Button1_ServerClick" style="width:50px; color:red;"/>

  protected void Button1_ServerClick(object sender, EventArgs e)
    {
       //介面有updatepanel下使用如下：
        ScriptManager.RegisterStartupScript(UpdatePanel1, this.Page.GetType(), "", "alertClick();", true);
        //如果沒有就如下程式碼
       // this.Page.ClientScript.RegisterStartupScript(this.Page.GetType(), "", "<script>alertClick();</script>", true);
    }
