Obsolete since Gecko 37 (Firefox 37 / Thunderbird 37 / SeaMonkey 2.34)
This feature is obsolete.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.

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 (").



Return value

A new string representing the original string wrapped in double-quotes, with any special characters escaped.


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.

str str.quote() eval(str.quote())
Hello world! "Hello world!" Hello world!
"Hello\n\tworld!" Hello
" \ — ' "\" \\ \u2014 '" " \ — '


Not part of any standard. Implemented in JavaScript 1.3.


if (!String.prototype.quote)
    String.prototype.quote = function(){
        return JSON.stringify( this ); // since IE8
