通过document.hidden属性判断当前页面是否是激活状态

网页当前状态判断，若不处于当前窗口则不发请求

var interval_output = null; function sendRequst() {     interval_output = setInterval(function () {        SetClock();    }, 60000); } sendRequst();

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')        sendRequst();   } else {      //console.log('页面非激活');       clearInterval(interval_output);  } } document.addEventListener(visibilityChangeEvent, onVisibilityChange);
