如何使用javascript在页面中实现工具提示？ [英] How to implement tooltip in a page using javascript?
问题描述
我有一个页面，其中有100个脚注，因此我想为这些脚注实现工具提示，即内容中提到的脚注在文档末尾有参考文献。所以我要求的是必须有一个javascript从文档的底部拉出文本，并显示为内容文档中悬停的footlink的工具提示。我有逻辑，但没有得到我应该如何实现。
要完成hove的内容段和脚注内容的段落。

推荐答案
你可以使用jQuery UI
You can use jQuery UI
<!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/1.11.3/themes/smoothness/jquery-ui.css">
<script src="//code.jquery.com/jquery-1.10.2.js"></script>
<script src="//code.jquery.com/ui/1.11.3/jquery-ui.js"></script>
<link rel="stylesheet" href="/resources/demos/style.css">
<script>
（function（） {
(function() {
（document）.tooltip（）;
}）;
< / script >
< style >
label {
display：inline-block;
宽度：5em;
}
< / style >
< / head >
< body >
< p > < a href = ＃ title = 这个小部件是什么 > 工具提示< ; / a > 可以附加到任何元素。当您使用鼠标将元素悬停在
时，title属性将显示在元素旁边的一个小框中，就像本机工具提示一样。< < span class =code-leadattribute> / p >
< p > 但由于它不是原生工具提示，因此可以设置样式。使用
构建的任何主题< href = http：// jqueryui。 com / themeroller / title = ThemeRoller：jQuery UI& s主题构建器应用程序 > ThemeRoller < / a >
将也相应地设置工具提示样式。< / p >
< p > 工具提示对表单元素也很有用，可以显示som每个字段上下文中的附加信息。< / p >
< p > < label = age > 您的年龄：< / label > < 输入 < span class =code-attribute> id = age title = 我们仅针对统计目的询问您的年龄。 > < / p >
< p > 将鼠标悬停在该字段上以查看工具提示。< / p >
< / body >
< / html >
( document ).tooltip(); }); </script> <style> label { display: inline-block; width: 5em; } </style> </head> <body> <p><a href="#" title="That'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'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>
