The htmlentities function escapes characters which have special meaning inside HTML by inserting HTML entities in their place (eg. & in place of &). See our article on ASCII Character Codes for more details. All functions have a complementary 'decode' function that pretty much does the op...
注意,即使字符串中包含双字节字符(而不是单字节的 ASCII 字符),也仍然会按单字符来计数。 JavaScript 字符 JavaScript 字符串由UTF-16 位码元组成;对多数字来说,每 16 位码元对应一个字符。换句话说,字符串的length属性表示字符串包含多少 16 位码元: ...
备注: 如果,出于某些原因,你需要自己解析一些 JavaScript 源,不要假设所有的标识符遵循 /[A-Za-z_$][\w$]*/ 模式(例如,仅 ASCII)!标识符的范围可以由正则表达式 /[$_\p{ID_Start}][$\u200c\u200d\p{ID_Continue}]*/u(不包含 unicode 转义序列)描述。 此外,JavaScript 允许在标识符中以 \u0000 ...

我建议将源代码文本控制在Basic Latin Unicode block(或者说ASCII)中。超出ASCII的字符应该避免使用。这能保证源码文本在编码时少出些问题。 ECMAScript 2015在语言层面上给出了JavaScript中String(字符串)的明确定义: String类型是由16比特无符号整型数值(“元素”)组成的集合,最少包含0个元素,最多包含253-1个元素...
