我在asp.net页面中有一个名为gvLineItems的gridView .. 我想抛出一些jquery以允许双击gridview的行并让它重定向到另一个页面：
<script src="include/jquery-1.5.1.min.js" type="text/javascript"></script>
<script type="text/javascript">
var selected = null;
$(document).ready(function(){
$("#divGridView table tbody tr").find("tr").dblclick(function(){
window.location = "<%#ResolveUrl("~/Default2.aspx")%>?record=" + $(this).find("td:first").text();
});
});
</script>
有人在这看到任何奇怪的事吗？
这是真正丑陋的asp.net ajax与div等...

这是我的编辑：
<script type="text/javascript">
var selected = null;
$(document).ready(function(){
$("#divGridView table tbody tr").dblclick(function(){
window.location = "<%#ResolveUrl("~/Default2.aspx")%>?ID=" + $(this).find("td:first").text();
});
});
</script>
我现在几乎已经开始工作......我可以看到正确的ID号，可以解决为什么重定向不起作用。

将gridview包含在<div id="divGridView" />中并尝试此
$(document).ready(function(){
$("#divGridView table tbody tr").dblclick(function(){
var id= $(this).find("td:first").text();
window.location = "<%#ResolveUrl("~/Default2.aspx")%>?record=" + id;
});
});
答案 1 :(得分：1)
您正在寻找获取ID的标记，$(this).find("td:first").text()有Visible=false，这会导致它无法呈现，因此jQuery无法找到它。
最简单的解决方案可能是将ID放入标记（如span）中，该标记仅在第一个显示列中使用display:none呈现为不可见的客户端

这是我最终做的事情：
<script type="text/javascript">
var selected = null;
$(document).ready(function(){
$("#divGridView table tbody tr").dblclick(function(){
//window.location = "<%#ResolveUrl("~/Search.aspx")%>?ID=" + $(this).find("td:first").text();
window.location = "myURL/Search.aspx?ID=" + $(this).find("td:first").text();
});
});
</script>
