概述
返回最后一个启用的样式表集合,当document.selectedStyleSheetSet属性发生变化时,该属性的值就会变化.
语法
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.
注意: 当调用
document.enableStyleSheetsForSet()方法之后,该属性的值也不会发生变化.例子
var lastSheetSet = document.lastStyleSheetSet;
if (!lastSheetSet) {
lastSheetSet = "Sheet not yet changed";
}
console.log("The last sheet set is: " + lastSheetSet);
