停止Attributes.Add将我的JavaScript事件代码转换为HTML [英] Stopping Attributes.Add from converting my JavaScript event code to HTML

问题描述

我使用Attributes集合的Add方法向Controls

添加了几个JavaScript事件（onchange，onkeypress等）。但是，如果

JavaScript代码包含某些字符，例如&或者<或几个其他人，它将它们转换成html，例如& amp; amp; amp; amp; amp; amp;或& lt;有时可能会导致我的脚本不起作用。如何阻止ASP.NET执行此操作？

谢谢。

I add several JavaScript events (onchange, onkeypress, etc.) to Controls
using the Add method of the Attributes collection. However, if the
JavaScript code contains certain characters, such as & or < or several
others, it converts them to html, such as &amp; or &lt; which can sometimes
cause my scripts not to work. How can I prevent ASP.NET from doing this?
Thanks.

Hi Nathan,

For that is the HTML en/decode classes.

I hope this helps,

那会如果我使用类似

System.Web.UI.HtmlTextWriter的东西，那就太棒了，但我只是在我的* .aspx文件中添加属性对象

声明性地创建。例如，我有以下

作为我的* .aspx文件的一部分：

< asp：TextBox ID =" txtRed" RUNAT = QUOT;服务器" MaxLength =" 3"

Width =" 35px"> 0< / asp：TextBox>

我的* .aspx.vb文件中包含以下内容：

txtRed.Attributes.Add（" onchange"，" if（this.value> = 0&& this.value< = 255）{"&

redslider.ClientSetFunctionName&"（this.value）;} else {this.value ="&

redslider.ClientGetFunctionName&"（）;}"）

当我的页面呈现时，如下所示（注意

&'和<用HTML表示替换）：

onchange =" if（this.value> = 0& amp;& amp; this.value& lt; = 255）{sliderRed_setvalue（this.value）;} else {this.va lue = sliderRed_getvalue （）;}"

Server.HtmlDecode（）方法对我没有帮助，因为

Attributes.Add（）方法接受一个字符串就像它的'第二个参数，和
Server.HtmlDecode（）在我的情况下对它没有任何影响，所以我会

实际上是传递相同的字符串。还有其他想法吗？谢谢。

That would be great if I were using something like the
System.Web.UI.HtmlTextWriter, but I am simply adding attributes objects
created declaratively in my *.aspx file. For example, I have the following
as part of my *.aspx file:
<asp:TextBox ID="txtRed" runat="server" MaxLength="3"
Width="35px">0</asp:TextBox>
And I have the following in my *.aspx.vb file:
txtRed.Attributes.Add("onchange", "if(this.value>=0&&this.value<=255){" &
redslider.ClientSetFunctionName & "(this.value);}else{this.value=" &
redslider.ClientGetFunctionName & "();}")
When my page is rendered, this comes out as the following (notice that the
&''s and < are replaced with their HTML representations):
onchange="if(this.value>=0&amp;&amp;this.value&lt; =255){sliderRed_setvalue(this.value);}else{this.va lue=sliderRed_getvalue();}"
The Server.HtmlDecode() method would not help me here because the
Attributes.Add() method takes a String as it''s second parameter, and
Server.HtmlDecode() would not have any effect on it in my case, so I would
actually be passing the same String. Any other ideas? Thanks.

Nathan，


你确定吗你不需要这个。 （在这个页面是一个很好的样本）
http://msdn2.microsoft.com/en-us/lib...ttributes.aspx


现在你正在使用这一个添加一个属性让我们说一个列表框，其中

在我的想法中肯定不是一块javascript
http://msdn2.microsoft.com/en-us/lib...ction.add .aspx


我希望这会有所帮助，

Nathan,

Are you sure you do not need this one. (In this page is a nice sample)
http://msdn2.microsoft.com/en-us/lib...ttributes.aspx

Now you are using this one to add an attribute let say to an listbox, which
is in my idea sure not a piece of javascript
http://msdn2.microsoft.com/en-us/lib...ction.add.aspx

I hope this helps,
