Escaping Literal Quotes in Strings	逃避字符串中的字面引用

逃避字符串中的字面引用

• 当你需要使用特殊字符，例如"在字符串内部时，你需要使用\来转义它。
• 如果使用双引号"的字符串，单引号'字符串中不需要进行转义。
• 如果使用单引号'的字符串，双引号"字符串中不需要进行转义。

解

var myStr = "I am a \"double quoted\" string inside \"double quotes\"."; 
 var otherStr = 'I am a \'single quoted\' string inside \'single quotes\'.'; 
 var noEscapeSingle = "There is no need to 'escape' the single quotes."; 
 var noEscapeDouble = 'There is no need to "escape" the double quotes.';
