var taskid = window.setTimeout(function,ms);window.setTimeout("alert('hello！')", 5000);2.間隔執(zhí)行任務(wù)
var taskid = window.setInteval(function,ms);
3.清除定時任務(wù)
window.clearTimeout(taskid);
4.清除間隔執(zhí)行任務(wù)
window.clearInteval(taskid);
打印屏幕
//長*寬console.log(screen.width + "*" + screen.height)
后退
window.history.back();
前進(jìn)
window.history.forward();
刷新
window.location.reload();//刷新window.location.href = window.location.href;//刷新
Go 前進(jìn)(x)步,后退(x)步,刷新(0),
window.history.go(x)
