escape() - JavaScript 编辑

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。

概览

废弃的 escape() 方法生成新的由十六进制转义序列替换的字符串. 使用 encodeURI 或 encodeURIComponent 代替.

语法

escape(str)

参数

str

待编码的字符串.

描述

escape 函数是全局对象的属性. 特色字符如: @*_+-./ 被排除在外.

字符的16进制格式值,当该值小于等于0xFF时,用一个2位转移序列: %xx 表示. 大于的话则使用4位序列:%uxxxx 表示.

示例

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

// special characters
escape("@*_+-./");    // "@*_+-./"
