What is the best possible way to pass a Mulitline String as function argument?

What will be the Best practice to pass Multiline String as a Javascript function's a开发者_运维问答rgument.

You can pass it a variable!

JavaScript strings can contain newline characters, so you don't have to do anything special. (Edit Actually, I suppose you do — you have to use an escape sequence; that's covered below.) Example:

var s = "This is line 1\nThis is line 2\nThis is line 3.";
alert(s);

...alerts

This is line 1
This is line 2
This is line 3

The full syntax of the escape sequences in JavaScript strings is (of course) in the specification, but here's a brief (probably incomplete) rundown:

• \n - newline
• \r - carriage return
• \t - tab
• \v - vertical tab
• \b - backspace
• \f - formfeed
• \u0100 - Unicode character 256 (e.g., the value is in hex, four digits)
• \xfd - Unicode character 253 (e.g., the value is in hex, two digits)
• \\ - backslash
• \" - double quote (useful when you're using double quotes to delimit a string literal)
• \' - single quote (useful when you're using single quotes to delimit a string literal)
