怎么通过后台 给 前台的标签里动态添加 html代码

[sirzxj]

比如

前台 有 个

<div id="div1"></div>

想在这里面添加html代码怎么写 ？

[booth.chen]

前台
<div id="div1"><asp:Literal ID="ltrlString" runat="server"></asp:Literal></div>

后台

ltrlString.Text="<b>ltrlString</b>";

[孟子E章]

<div id="div1" runat="server"></div>


div1.InnerHtml = "html代码"

<div id="div1"><%=_str %></div>

后
protected string _str ="test";

后台：

        return strBody;
    }

前台：

<div><%=quyu_shiyonglv%></div>

<div id="div1" runat="server"></div>


div1.InnerHtml = "html代码"
[/Quote]

正解

[子夜__]

后台
string str="<div id=\"div1\" runat=\"server\"></div>";
前台
<%=str %>

[阳明 to life]

<div id="div1" runat="server"></div>
后台
this.div1.InnerHTML="";
字符串中填写对应的HTML代码就行了
