CSS: escape() static method

The CSS.escape() static method returns a string containing the escaped string passed as parameter, mostly for use as part of a CSS selector.





The string to be escaped.

Return value

The escaped string.


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'); // "\ufffd", the Unicode REPLACEMENT CHARACTER

In context uses

To escape a string for use as part of a selector, the escape() method can be used:

const 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:

const element = document.querySelector(`a[href="#${CSS.escape(fragment)}"]`);
