//页面代码 （简化）
<asp:TextBox ID="tbOperation2" runat="server" onclick="buttonclick($(this))"
CssClass="ui-button-icons-only" Text="按钮"></asp:TextBox>
<div id="editdialog" title="Basic dialog">
<div>
<label onclick="clickEdit();" class="labelbutton">

</div>
<div>
<label onclick="clickView();" class="labelbutton">
View</label>
</div>
<div>
<label onclick="clickBuild();" class="labelbutton">

</div>
</div>



<script type="text/javascript"> //页面初始化的时候
var staticsignal;
$(function() {
// a workaround for a flaw in the demo system (http://dev.jqueryui.com/ticket/4375), ignore!
$(":input.ui-button-icons-only").button(); //更改textbox的样式
});
</script>

<script type="text/javascript">
function buttonclick(e)
{
var offset=e.offset();//得到offset
var x=offset.left;
var y=offset.top;
$("#editdialog").dialog({
autoOpen:true,
draggable:true,
resizable:false,
position:[x,y+35], //设置坐标
width:150
});
$(".ui-dialog-titlebar").hide();
$('a.ui-dialog-titlebar-close').hide();
