小tips:jquery datapicker中,用图片按钮弹出日历框
在jquery datapicker中,如果要在日历框旁边的小图片,当点小图片时,
弹出日历框,可以这样写:
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
    <title></title>
    <link rel="stylesheet"
    href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.6/themes/base/jquery-ui.css"

    <script type="text/javascript">
        $(function () {

            $('#<%= txtDate.ClientID  %>').datepicker({
                buttonImage: '../../images/icons/calendar.png',
                buttonImageOnly: true,
                showOn: 'button'
            });
        });

    </script>
</head>
