Question

我有一个使用弹出窗口的jquery示例：

<div id="dialog-form" title="Create new user">
<p class="validateTips">All form fields are required.</p>

<form>
<fieldset>
  <label for="name">Name</label>
  <input type="text" name="name" id="name" value="Jane Smith" class="text ui-widget-content ui-corner-all">
  <label for="email">Email</label>
  <input type="text" name="email" id="email" value="jane@smith.com" class="text ui-widget-content ui-corner-all">
  <label for="password">Password</label>
  <input type="password" name="password" id="password" value="xxxxxxx" class="text ui-widget-content ui-corner-all">

  <!-- Allow form submission with keyboard without duplicating the dialog button -->
  <input type="submit" tabindex="-1" style="position:absolute; top:-1000px">
</fieldset>
</form>
</div>

当我点击编辑时，它应该获取信息并编辑行但不起作用。

以下是demo

请有人帮助我吗？

这是代码js：

        .text( t )
        .addClass( "ui-state-highlight" );
      setTimeout(function() {
        tips.removeClass( "ui-state-highlight", 1500 );
