设置控件的属性时，ASP.NET引号字符编码导致问题 [英] ASP.NET quote character encoding causes problems when setting a control's property

问题描述

我有一个ASP.NET Web应用程序，并在某一点上我这样做：

I have an ASP.NET web application and at a certain point I do this:

mycontrol.stringparameterforjscript = "document.getElementById('" + myotherparam + "').value = 'Hello'";

的问题是，这件事情不工作。
正如你所看到的这台有些标记某些事件的脚本。那么当页面redered问题是，我的参数是这样的：

The problem is that this thing does not work. As you can see this sets a javascript in some event of some tag. Well when the page is redered the problem is that my parameter look like this:

<textarea onfocus="document.getElementById(&#39;myvalue&#39;).value = &#39;Hello&#39;"></textarea>

我必须precise这个文本框，我想设置位于一个ListView的InsertTemplate则内部，也不是那么容易并初始化。为此，我插入我的初始化code，你我的文本框的Load事件处理程序里面看到的。我可以说你一件事：如果code中提到的网页随意设一个文本框，我叫这块code从页面的加载事件处理程序，这将很好地工作。但我不知道如何在这种特殊情况下做的。

I must precise that this textbox I'm trying to set is located inside a InsertItemTemplate of a ListView and it is not so easy to intialize. For this reason I inserted my initialization code that you see inside the load event handler of my textbox. I can say you one thing: If this code referred to a text box located freely in the page and I called this piece of code from the load event handler of the page, this would work well. But I do not know how to do in this particular case.

我也在考虑建立一个webcntrol来处理这样的问题的可能性。我真的不知道什么是在这种情况下，最好的做法。

I'm also considering the possibility to create a webcntrol to handle such a problem. I don't really know what's the best practice in this case.

推荐答案

我想你可能需要在你的作业都字符串的@，并删除斜杠：

I think you might need the @ on both string literals in your assignment, and remove the slashes:

mycontrol.stringparameterforjscript = @"document.getElementById('" + myotherparam + @"').value = 'Hello'";

的修改的

我怎么做的：

在在.aspx：

<asp:Textbox ID="tbTest" runat="server" TextMode="MultiLine" />

在code：

protected void Page_Load(object sender, EventArgs e)
{
    string myotherparam = "paramval";
    tbTest.Attributes.Add("onfocus", @"document.getElementById('" + myotherparam + @"').value = 'Hello'");
}

结果输出：

<textarea name="tbTest" rows="2" cols="20" id="tbTest" onfocus="document.getElementById('paramval').value = 'Hello'"></textarea>
