StringEscapeUtils.escapeEcmaScript介绍

[英]Escapes the characters in a String using EcmaScript String rules.

Escapes any values it finds into their EcmaScript String form. Deals correctly with quotes and control-chars (tab, backslash, cr, ff, etc.)

So a tab becomes the characters '\' and 't'.

The only difference between Java strings and EcmaScript strings is that in EcmaScript, a single quote and forward-slash (/) are escaped.

Note that EcmaScript is best known by the JavaScript and ActionScript dialects.

Example:

input string: He didn't say, "Stop!" 
output string: He didn\'t say, \"Stop!\"

[中]使用EcmaScript字符串规则转义字符串中的字符。
将找到的任何值转义到EcmaScript字符串形式中。正确处理引号和控制字符（制表符、反斜杠、cr、ff等）
所以一个标签变成了字符“\”和“t”。
Java字符串和EcmaScript字符串之间的唯一区别在于，在EcmaScript中，单引号和正斜杠（/）被转义。
请注意，EcmaScript最为人所知的是JavaScript和ActionScript方言。
例子：

input string: He didn't say, "Stop!" 
output string: He didn\'t say, \"Stop!\"
