JS string fontsize()

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。

The fontsize() method creates aHTML element that causes a string to be displayed in the specified font size.

Usage note: The element has been removed in HTML5 and shouldn’t be used anymore. Instead web developers should use CSS properties.

语法

str.fontsize(size)

参数

size

An integer between 1 and 7, a string representing a signed integer between 1 and 7.

返回值

A string containing a HTML element.

描述

When you specify size as an integer, you set the font size of str to one of the 7 defined sizes. When you specify size as a string such as “-2”, you adjust the font size of str relative to the size set in the tag.

示例

使用fontsize()方法

The following example uses string methods to change the size of a string:

var worldString = 'Hello, world';

console.log(worldString.small());     // Hello, world
console.log(worldString.big());       // Hello, world
console.log(worldString.fontsize(7)); // Hello, world

With the element.styleobject you can get the element’s style attribute and manipulate it more generically, for example:

document.getElementById('yourElemId').style.fontSize = '0.7em';
