Javascript - 如何从动态字符串内容中转义双引号，意外标识符错误

Question

Have used to Bind Login User name from portal to a Javascript variable. User name contains either SingleQuote or DiubleQuote sometimes.

My Javascript code failed to read string with DiubleQuote.

EX:

var userName = "Happy and "Care" Ltd"; -  error: unknown: Unexpected token, expected ";"
var userName1 = 'Happy and Care's Ltd'; - error: unknown: Unexpected token, expected ";"

You can use backticks `` like this:

 var userName = `Happy and "Care" Ltd`; var userName1 = `Happy and Care's Ltd`; console.log(userName) console.log(userName1)

Backslash is used as a escape character. For example you can use like this:

var userName1 = 'Happy and Care\'s Ltd';
