Question

   例如
      <img src="<%# Eval("ImgName")%>" alt="" width="150" height="112" />
后台按钮事件中我 怎么获取绑定的这个ImgName。。

Answer 1

或者直接在绑定事件中去DataItem中去取值。

Answer 2

jquery:
<img id="#a" src="a\b.gif"/>
alert($('#a').src);
js:<img src="img/logo.gif" onclick="alert(this.getAttribute(&quot;src&quot;,2))" />

Answer 3

<img id="myImg" runat="server" src="<%# Eval("ImgName")%>" alt="" width="150" height="112" />后台事件中，
假如你将img放到了datalist中可以这样：
string url=((HtmlImage)datalist1.Items[0].FindControl("myImg")).Src;假如你将img放到了Gridview中可以这样：
string url=((HtmlImage)Gridview1.Rows[0].FindControl("myImg")).Src;其他类推，注意红色部分的索引值
