可以通过document.hidden属性判断当前页面是否是激活状态。
兼容性:IE10+,Firefox10+,Chrome14+,Opera12.1+,Safari7.1+
兼容性写法示例:
var hiddenProperty = 'hidden' in document ? 'hidden' :
'webkitHidden' in document ? 'webkitHidden' :
'mozHidden' in document ? 'mozHidden' :
null;
var visibilityChangeEvent = hiddenProperty.replace(/hidden/i, 'visibilitychange');
var onVisibilityChange = function(){
if (!document[hiddenProperty]) {
console.log('页面激活');
}else{
console.log('页面非激活')
}
}
document.addEventListener(visibilityChangeEvent, onVisibilityChange);
