String.prototype.fixed()

已废弃
该特性已经从 Web 标准中删除，虽然一些浏览器目前仍然支持它，但也许会在未来的某个时间停止支持，请尽量不要使用该特性。

fixed()方法创建了一个<tt>标签元素将字符串包裹起来，从而让这个字符串里面的内容具有固定间距。

语法

str.fixed()

Return value

返回一个表示 <tt> HTML 元素的字符串。

描述

fixed() 方法将一个字符串包裹在<tt></tt>标签中，比如: "<tt>str</tt>".

举例

使用fixed()

下面的示例代码使用这个fixed方法来改变字符串的格式：

var worldString = 'Hello, world';
console.log(worldString.fixed()); // "<tt>Hello, world</tt>"
