＆LT;脚本＆GT; ...＆LT; / SCRIPT＆GT;内Repeater控件code没有出现在源$ C ​​$ C页面上呈现 [英] <script>...</script> inside a repeater control code not showing up in the source code on page render

问题描述

我有一个中继器控制，其中的＆lt;％＃DataBinder.Eval的（的Container.DataItem，显示）％>部分显示不出来。该显示卖场设置为code如下：

  item.Display =＆LT;脚本类型=文/ JavaScript的'＆GT; AudioPlayer.embed（'ffcedea7-
4822-465f-85b6-89924f7b81fa'，{音效档：http://s3.amazonaws.com/blah/af8g7fd3-1793
-4b5e-92b7-9d11ad1cc19c.mp3'}）;＆下; /脚本＆gt;中;
 

在页面加载，音频嵌入文件没有显示出来。在code甚至没有在源代码中出现。如果我结束脚本标签后面添加一个随机字符串，随机字符串会显示出来。

  item.Display =＆LT;脚本类型=文/ JavaScript的'＆GT; AudioPlayer.embed（'ffcedea7-4822-4
65F-85b6-89924f7b81fa'，{音效档：http://s3.amazonaws.com/blah/af8g7fd3-1793-4b
5E-92b7-9d11ad1cc19c.mp3'}）;＆LT; / SCRIPT＆GT;这是随机字符串;
 

所以，在页面的源代码就会产生这是随机字符串，而不是剧本的部分。

有谁知道是什么原因造成这个问题以及如何修复？谢谢！

编辑：这里是中继code：

解决方案

也许你有你的页面上的某些安全设置或webconfig ...

我试图重现你的情况在一个全新的页面，但实际工作。

 大众A级
{
    公共字符串显示{搞定;组; }
}保护无效的Page_Load（对象发件人，EventArgs的发送）
{
    VAR名单=新名单，LT; A＆GT;（）;    VAR一个=新的A（）;
    a.Display =＆LT;脚本＆GT;警报（'你好'）＆LT; / SCRIPT＆GT; S＆LT; BR /＆gt;中;    list.Add（一）;    rep.DataSource =清单;
    rep.DataBind（）;
}
 

和页面

 ＆LT; ASP：直放站ID =代表=服务器＆GT;
    ＆LT;＆ItemTemplate中GT;
        ＆LT;％＃DataBinder.Eval的（的Container.DataItem，显示）％GT;
    ＆LT; / ItemTemplate中＆GT;
＆LT; / ASP：直放站＆GT;
 

或许你可以尝试设置显示与 HttpUtility.UrlEn code 和<得到它code> HttpUtility.UrlDe code ...

I have a repeater control where the <%#DataBinder.Eval(Container.DataItem, "Display")%> part doesn't show up. The code that the "Display" stores is set as follows:

item.Display = "<script type='text/javascript'>AudioPlayer.embed('ffcedea7-
4822-465f-85b6-89924f7b81fa', {soundFile: 'http://s3.amazonaws.com/blah/af8g7fd3-1793
-4b5e-92b7-9d11ad1cc19c.mp3'});</script>";

After the page load, the audio embed file doesn't show up. The code doesn't even show up in the source. If I add a random string after the ending script tag, that random string will show up.

item.Display = "<script type='text/javascript'>AudioPlayer.embed('ffcedea7-4822-4
65f-85b6-89924f7b81fa', {soundFile: 'http://s3.amazonaws.com/blah/af8g7fd3-1793-4b
5e-92b7-9d11ad1cc19c.mp3'});</script> THIS IS THE RANDOM STRING";

So, on the page source it will have " THIS IS THE RANDOM STRING" but not the script part.

Does anyone know what is causing this issue and how it can be fixed? Thanks!

Edit: Here is the repeater code:

    <asp:Repeater ID="repeaterAddable" runat="server">
    <ItemTemplate>
        <div class="background-white">
            <div style="padding: 15px;">
                <table style="width: 100%" cellspacing="5">
                    <tr>
                        <td colspan="3" align="right">
                            Include this? <input type="checkbox" name="include<%#DataBinder.Eval(Container.DataItem, "Index")%>" />
                        </td>
                    </tr>
                    <tr>
                        <td style="width: 30%;" valign="top">

                        </td>
                        <td style="width: 30%;" valign="top">
                            <div class="media">

                                <%#DataBinder.Eval(Container.DataItem, "Display")%>

                            </div>
                        </td>
                        <td style="width: 30%;" valign="top">

                        </td>
                    </tr>
                </table>
            </div>
        </div>
        <br />
    </ItemTemplate>
</asp:Repeater>

解决方案

Maybe you have some safe settings on your page or webconfig...

I tried to reproduce your situation in a brand new page, but it actually worked.

public class A
{
    public string Display { get; set; }
}

protected void Page_Load(object sender, EventArgs e)
{
    var list = new List<A>();

    var a = new A();
    a.Display = "<script>alert('hi')</script>S<br/>";

    list.Add(a);

    rep.DataSource = list;
    rep.DataBind();
}

And in the page

<asp:Repeater ID="rep" runat="server">
    <ItemTemplate>
        <%# DataBinder.Eval(Container.DataItem, "Display") %>
    </ItemTemplate>
</asp:Repeater>

Perhaps you can try to set the Display with HttpUtility.UrlEncode and get it with HttpUtility.UrlDecode...
