JS调用后台Button事件不成功

Question

想双击GridView某行时，通过JS函数调用Button4的Click事件，但是无法成功
        protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                e.Row.Attributes.Add("ondblclick", "rowdata()");
            }
        }
后台Click事件
        protected void Button4_Click(object sender, EventArgs e)
        {
            TextBox1.Text = Button4.ID;
        }
前台JS函数
    <script type="text/javascript">
       function rowdata()
       {
           document.getElementByID("Button4").onclick();
       }
    </script>
请看看哪里不对，document.getElementByID("Button4").onclick()是这样写吗

Answer 1

你把Button4放到隐藏域里，按钮别设置隐藏

Answer 2

直接调用JQuery库,然后
$(document).ready(function(){
  $("按钮ID").click();
})

Answer 3

<script type="text/javascript">
  function rowdata()
  {
  document.getElementByID("Button4").onclick();
  }
  </script>
把上面的脚本放在form后面

Answer 4

是click，不是onclick
document.getElementByID("Button4").click();

Answer 5

ondblclick？  GridView双击返回 收藏

Answer 6

function rowdata(){
   document.getElementByID("<%=Button4.ClientID%>").click();
}

Answer 7

Button4没设置隐藏
改成document.getElementByID("Button4").click()也无效
放到form后面也不行

Answer 8

没有引用母版页
  <script type="text/javascript">
  function rowdata()
  {
  document.getElementByID("Button4").onclick();
  }
  </script>
这段是放在head段里的

Answer 9

正解，，因为服务器控件生成HTML的时候，ID也是自动生成的，，你要用ＣｌｉｅｎｔＩＤ获取

Answer 11

document.getElementByID("<%=Button4.ClientID%>").click()这句也不起作用，就用click()吗，后台是protected void Button4_Click(object sender, EventArgs e)事件

Answer 12

晕死，我就是要看你的GridView和Button4的aspx代码……

Answer 13

是不是因为TextBox1放在一个UpdatePanel里的原因啊，双击的是GridView不是Button4，所以无法刷新Textbox1，怎样添加GridView双击触发UpdatePanel啊

        </div>

Answer 16

把Button4也放到同一个updatePanel里去

Answer 17

document.getElementByID("Button4").onclick();
JS里区分大小的吧!
getElementByID 改成 getElementById
