This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.
Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
The non-standard quote() method returns a copy of the string, replacing various special characters in the string with their escape sequences and wrapping the result in double-quotes (").
Syntax
str.quote()Return value
A new string representing the original string wrapped in double-quotes, with any special characters escaped.
Examples
In the table below the quote() method replaces any special characters and wraps the strings in double-quotes. Also note the third column where a wrapped eval() evaluates the escape sequences again.
