.net与母版页如何使用变量在.aspx页面上使用javascript查找控件 [英] .net with master page how to use a variable to find a control on an .aspx page using javascript

问题描述

Hello...
I am trying to use javascript document.getElementById() to find a server control on my page.
The page uses a master page.
The challenge is the control has a variable name.
In this case, these are textboxes with IDs like customer_123, customer_654

The javascript function is passed a variable for each control like thisid
I can always use something like   document.getElementByID('ctl00_maincontent_customer' + thisid)).value
But, I do not like using that hard-codes syntax and prefer to use
document.getElementByID('<%=thiscontrolid.ClientID%>').value

I cannot find a way to create the [thiscontrolid] as a variable whose value is partially passed to the function.

For example.  Something like:
function getMyControl(thisid)
{
  document.getElementByID("<%=customer_[thisid].ClientID%>").value
}

But I have not been able to find a syntax that will allow me to do this.
Any suggestions would be appreciated.

What I have tried:

<pre>document.getElementByID("<%=customer_" & thisid.ClientID%>").value

推荐答案

你可以尝试jquery，这很容易。< br $>


webform1代码：

Hi,
you can try jquery and it is very easy.

webform1 code:

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server"><br />
    <div runat="server" id="customer_1"><br />
        I am first control</div><br />
    <div runat="server" id="customer_2"><br />
        I am second control</div>        <br />
</asp:Content>

在MasterPage上使用以下脚本：

On MasterPage use below script:

<script type="text/javascript" src="jquery-1.11.0.min.js"></script>

//需要提供jquery路径

//need to give jquery path

<script type="text/javascript">

（ document ）。ready（ function （）{
getMyControl（ 1 ）;
getMyControl（ 2 ）;
}）;

function getMyControl（thisid）{
var createnew = < span class =code-string> [id

(document).ready(function() { getMyControl(1); getMyControl(2); }); function getMyControl(thisid) { var createnew = "[id

= customer _ + thisid + ];
var controlhtml =

=customer_" + thisid + "]"; var controlhtml =
