问题描述

嗨

我想创建一个jscript函数，将文本框的值设置为

数据网格，但问题是如何获取该名称的文本框和

将它发送到我的jscript函数????文本框在一个TemplateColumn中


将Idea发送给函数控件的名称，然后将其传递给

另一个窗口然后这个子窗口必须设置

控件的值。但为了简单起见，问题变得简陋，以获得名称

文本框


这是我的fHelpItm jscript函数的调用，就像你看到我关联

调用IMG控件的onclick事件

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

< EditItemTemplate>

Codigo< asp：TextBox id =" txtCod" runat =" server"

Width =" 87px">< / asp：TextBox>

< IMG id =" imgBuscar"的onclick = QUOT;的JavaScript的 的：fHelpItm（ txtCod）" alt =""

src =" ../ Images / iconBuscar.jpg">

< / EditItemTemplate>

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


函数简化函数是这样的

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

功能fHelpItm（Codigo）

{

if确认（''你想为''+ Codigo设置一个值）

document.forms [0] .elements [Codigo] .value =''Hello world''<<<这里

就是问题

}

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

jscript说控件的名称是txtCod。不是一个对象，并且

是正确的，因为名称肯定是Datagrid__ctl2_txtCod

所以问题是如何获得控件的正确名称<谢谢你的帮助，因为这让我很生气!!!

再见

解决方案

嗨！

您无法使用其ID（txtCod）获取TextBox，因为在数据网格中，您需要具有相同ID的许多项目（此处为文本框）。但是在一个页面中你不能

有两个具有相同ID的控件。因此，框架为所有控件添加了一些前缀

。这就是为什么它就像Datagrid__ctl2_txtCod。如果你想要

在客户端上使用文本框（在js函数中）你必须使用

带有前缀的ID


希望有所帮助！

问候，

HI Kostadin


我明白了，但我怎样才能得到真实姓名。控制???怎么能

我建立名字????


onclick =" javascript ：fHelpItm（''txtCod''）" alt =""

src =" ../ Images / iconBuscar.jpg">

^

我必须如何正确这部分?? ---------- |


我猜这是关键吗？如何写控制名称以便

发送给我的jscript函数

谢谢

< blockquote>我脑海中唯一出现的是：

1.处理网格的ItemDataBound事件

2.在处理程序内部构造TextBox的ID（Datagrid__ctl2_txtCod ）

3.通过e.Item.FindControl（" myButton"）获取按钮

4.添加属性 - myButton.Attributes.Add（" onclick"，

fHelpItm（''Datagrid__ctl2_txtCod''））;


这很复杂，但我想不出更好的方法来实现这个目标。

对不起！

希望有所帮助！

Hi
I wanna to create a jscript function that sets the value of a textbox into a
datagrid, But the problem is How can I obtain the name of the textbox and
send it to my jscript function???? The textbox is in a TemplateColumn

The Idea is sent to the funcion the name of the control and then pass it to
another window and then this child window must set the values of the
control. But for simplicity the problem get reduced to obtain the name of
the textbox

This is the call of my fHelpItm jscript function, like you see I associate
the call to onclick event for the IMG control
==================
<EditItemTemplate>
Codigo<asp:TextBox id="txtCod" runat="server"
Width="87px"></asp:TextBox>
<IMG id="imgBuscar" onclick="javascript:fHelpItm(''txtCod'')" alt=""
src="../Images/iconBuscar.jpg">
</EditItemTemplate>
==================

the function simplified function is something like this
=======================
function fHelpItm(Codigo)
{
if confirm('' Do you wanna set a value for '' + Codigo)
document.forms[0].elements[Codigo].value =''Hello world'' <<<HERE
is the problem
}
=====================
jscript says that the name of the control "txtCod" is not an object and that
is correct because the name sure is something like "Datagrid__ctl2_txtCod"
so the question is How can I obtain the correct name of the control
THANKSSSSSSS FOR YOUR HELP because this is getting me crazy!!!
bye

解决方案

Hi!
You cannot get the TextBox using its ID (txtCod), because in datagrid you
have many items (here textboxes) with the same ID. But in one page you cannot
have two controls with the same ID. So, the framework places some prefix to
all the controls. That''s why it is like "Datagrid__ctl2_txtCod". If you want
to have the textbox available on the client (in js function) you have to use
the ID with the prefix

Hope that helps!

The only thing that appears in my mind is:
1. Handle the ItemDataBound event of the grid
2. Inside the handler construct the ID of the TextBox (Datagrid__ctl2_txtCod)
3. Get your button through e.Item.FindControl("myButton")
4. Add attribute - myButton.Attributes.Add("onclick",
fHelpItm(''Datagrid__ctl2_txtCod''));

It''s quite complicated, but I can''t think of better way to achieve this.
Sorry!
