Document.lastStyleSheetSet

The Document.lastStyleSheetSet property returns the last enabled style sheet set. This property's value changes whenever the document.selectedStyleSheetSet property is changed.

Syntax

var lastStyleSheetSet = document.lastStyleSheetSet

On return, lastStyleSheetSet indicates the style sheet set that was most recently set. If the current style sheet set has not been changed by setting document.selectedStyleSheetSet, the returned value is null.

Example

let lastSheetSet = document.lastStyleSheetSet;

if (!lastSheetSet) {
  lastSheetSet = 'Style sheet not yet changed';
}
else {
  console.log('The last style sheet set is: ' + lastSheetSet);
}
