window.close(); 关闭当前window.opener.close(); 关闭父窗口定时任务
1.定时任务
var taskid = window.setTimeout(function,ms);window.setTimeout("alert('hello！')", 5000);2.间隔执行任务
var taskid = window.setInteval(function,ms);3.清除定时任务
window.clearTimeout(taskid);4.清除间隔执行任务
window.clearInteval(taskid);打印屏幕
//长*宽console.log(screen.width + "*" + screen.height)后退
window.history.back();前进
window.history.forward();刷新
window.location.reload();//刷新window.location.href = window.location.href;//刷新Go 前进(x)步,后退(x)步,刷新(0),
