unescape()

已废弃的unescape() 方法计算生成一个新的字符串，其中的十六进制转义序列将被其表示的字符替换。上述的转义序列就像decodeURIComponent 替代本方法。

注意：不要使用 unescape去解码URLS，使用 decodeURI替代。

语法

unescape(str)

参数

str
被编码过的字符串。

返回值

一个未被转义的新字符串。

描述

unescape函数是全局对象的一个属性。

示例

unescape('abc123');     // "abc123"
unescape('%E4%F6%FC');  // "äöü"
unescape('%u0107');     // "ć"
