如何在javascript中获取嵌入式控件的ID？ [英] how to get ID of embedded control in javascript?

问题描述

有一个详细信息视图，其中包含editmode中的文本框。

如何在javascript中获取文本框的ID？

我试过这个：

< asp：DetailsView ID =" DetailsView1" RUNAT = QUOT;服务器" >

< asp：TemplateField>

< EditItemTemplate>

< asp：TextBox ID =" TextBox1" runat =" server">< / asp：TextBox>

< / EditItemTemplate>

< / asp：TemplateField>

< / asp：DetailsView>


< script type =" text / javascript">

var txt = document.getElementById（'' TextBox1''）

....


谢谢

Dan

解决方案

我从未使用过DetailsView控件，但是我使用了模板化的

控件，而且我有足够的ASP.NET经验来了解

生成的id几乎不是给服务器控件ID

属性的id。您将需要使用FindControl（）方法和ClientID

属性。

感谢您的回复，

但我的代码，我得到错误：

''TextBox1''未声明''


Textbox1嵌入在detailsview1中。

Hi,

There is a detailsview which contains a textbox in editmode.
How to get the id of the textbox in javascript?
I tried this:
<asp:DetailsView ID="DetailsView1" runat="server" >
<asp:TemplateField>
<EditItemTemplate>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</EditItemTemplate>
</asp:TemplateField>
</asp:DetailsView>

<script type="text/javascript">
var txt=document.getElementById(''TextBox1'')
....

Thanks
Dan

解决方案

I have never used the DetailsView control, but I have used templated
controls and I have more than enough experience with ASP.NET to know that
the generated id is almost never the one given to the server control ID
attribute. You will need to use the FindControl() method and the ClientID
property.

Thanks for replying,
but with my code, i get the error:
''TextBox1'' is not declared''

Textbox1 is embedded in detailsview1.
