The StyleSheetList
interface represents a list of StyleSheet
.
It is an array-like object but can't be iterated over using Array
methods. However It can be iterated over in a standard for
loop over its indices, or converted to an Array
.
Examples
Get document styleSheet objects with for loop
for (let i = 0; i < document.styleSheets.length; i++) {
let styleSheet = document.styleSheets[i];
}
Get all CSS rules for the document using Array methods
const allCSS = [...document.styleSheets] .map(styleSheet => { try { return [...styleSheet.cssRules] .map(rule => rule.cssText) .join(''); } catch (e) { console.log('Access to stylesheet %s is denied. Ignoring...', styleSheet.href); } }) .filter(Boolean) .join('\n');
