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escape里介绍的一样。因为 unescape 已经废弃,建议使用 decodeURI或者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。

简述

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"
