This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for the proper prefixes to use in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the spec changes.
The CSS.escape() static method returns a DOMString containing the escaped string passed as parameter, mostly for use as part of a CSS selector.
Syntax
escapedStr = CSS.escape(str);
Parameters
- str
- The
DOMStringto be escaped.
Examples
Basic results
CSS.escape(".foo#bar") // "\.foo\#bar"
CSS.escape("()[]{}") // "\(\)\[\]\{\}"
CSS.escape('--a') // "--a"
CSS.escape(0) // "\30 ", the Unicode code point of '0' is 30
CSS.escape('\0') // InvalidCharacterError
In context uses
To escape a string for use as part of a selector, the escape() method can be used:
var element = document.querySelector('#' + CSS.escape(id) + ' > img');
The escape() method can also be used for escaping strings, although it escapes characters that don't strictly need to be escaped:
var element = document.querySelector('a[href="#' + CSS.escape(fragment) + '"]');
