如何从jquery获取值表或gridview tr td。 [英] How to get value table or gridview tr td from jquery.

问题描述

function mainCall（）{

var lb = document.getElementById（'gvlblName'）。innerHTML;

alert（lb）;



var name = $（obj）.closest（'tr'）。find（'td：eq（0）'）。text（）;

alert（姓名）;

}



========================= ===============================================



< asp：GridView ID =grdRegisterrunat =serverAutoGenerateColumns =false>

< columns>

< asp：TemplateField HeaderText =UserName>

< itemtemplate>



< asp：Label ID =gvlblNamerunat =servertext ='<％＃Eval（UserName）％>'>















================================ =======================================

错误弹出：当前上下文中不存在名称'gvlblName'

错误弹出：undefiend



我尝试了什么：



var name = $（obj）.closest（'tr'）。find（'td：eq（0）'）。text（）; // 1,2还

alert（name）;

function mainCall() {
var lb = document.getElementById('gvlblName').innerHTML;
alert(lb);

var name = $(obj).closest('tr').find('td:eq(0)').text();
alert(name);
}

========================================================================

<asp:GridView ID="grdRegister" runat="server" AutoGenerateColumns="false" >
<columns>
<asp:TemplateField HeaderText="UserName">
<itemtemplate>

<asp:Label ID="gvlblName" runat="server" text='<%#Eval("UserName")%>'>







=======================================================================
error popup : The name 'gvlblName' does not exist in the current context
error popup : undefiend

What I have tried:

var name = $(obj).closest('tr').find('td:eq(0)').text(); // 1, 2 also
alert(name);

推荐答案

（obj）.closest（'tr'）。find（' td：eq（0）'）。text（）;

alert（name）;

}

你做错了。你不能得到这样的标签。 Label的ID在渲染时会被更改，因为它位于每一行内部。



因此，您需要首先获取网格视图元素并在其中搜索特定内容根据你的逻辑行或其他东西。

You are doing wrong. You can't get the label like that. Label's id is changed when it gets rendered, as it is inside every row.

So, you need to get the grid view element first and search inside it for a particular row or something according to your logic.
