我正在尝试使用js并创建带有一些"信息文本"的"描述框"

HTML

<head>
<script type="text/javascript" src="onmo.js"></script>
</head>
<body>
    <div> <a onmouseover="info()"  href="http://www.google.com"> google </a> </div> 
</body>

JS-

function info() {}

我不知道是哪一个代码创建了所谓的"描述框"和一些文本。有什么帮助吗？没有css。

您可以将jquery-ui tooltip用于此目的。

这里有一个链接，文档中有很好的例子：链接

来自jqueryui站点的示例：

<!doctype html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <title>jQuery UI Tooltip - Default functionality</title>
  <link rel="stylesheet" href="//code.jquery.com/ui/1.11.4/themes/smoothness/jquery-ui.css">
  <script src="//code.jquery.com/jquery-1.10.2.js"></script>
  <script src="//code.jquery.com/ui/1.11.4/jquery-ui.js"></script>
  <link rel="stylesheet" href="/resources/demos/style.css">
  <script>
  $(function() {
    $( document ).tooltip();
  });
  </script>
  <style>
  label {
    display: inline-block;
    width: 5em;
  }
  </style>
</head>
<body>
 
<p><a href="#" title="That&apos;s what this widget is">Tooltips</a> can be attached to any element. When you hover
the element with your mouse, the title attribute is displayed in a little box next to the element, just like a native tooltip.</p>
<p>But as it's not a native tooltip, it can be styled. Any themes built with
<a href="http://jqueryui.com/themeroller/" title="ThemeRoller: jQuery UI&apos;s theme builder application">ThemeRoller</a>
will also style tooltips accordingly.</p>
<p>Tooltips are also useful for form elements, to show some additional information in the context of each field.</p>
<p><label for="age">Your age:</label><input id="age" title="We ask for your age only for statistical purposes."></p>
<p>Hover the field to see the tooltip.</p>
 
 
</body>
</html>

当悬停链接时，这将显示一些文本：

 <a href="http://www.google.com" title="This is Google"> google </a>
