我正在使用rails，並不喜歡有2個地方寫代碼高度依賴。 所以我修改了下面代碼中的jquery-ui對話框示例。見executaDialogModal（）
<meta charset="utf-8">
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript" src="jquery-ui.js"></script>
<link rel="stylesheet" type="text/css" media="screen" href="jquery-ui.css" />
<style>
body { font-size: 62.5%; }
label, input { display:block; }
input.text { margin-bottom:12px; width:95%; padding: .4em; }
fieldset { padding:0; border:0; margin-top:25px; }
h1 { font-size: 1.2em; margin: .6em 0; }
div#users-contain { width: 350px; margin: 20px 0; }
div#users-contain table { margin: 1em 0; border-collapse: collapse; width: 100%; }
div#users-contain table td, div#users-contain table th { border: 1px solid #eee; padding: .6em 10px; text-align: left; }
.ui-dialog .ui-state-error { padding: .3em; }
.validateTips { border: 1px solid transparent; padding: 0.3em; }
</style>
<script>
