子窗口可以重写父窗口的location.href,
try{
if(window.location.href != parent.window.location.href){parent.window.location.href = window.location.href}
}catch(e){
parent.window.location.href = window.location.href ··
}
try{
parent.window.location.href
}catch(e){
parent.window.location.href = window.location.href
}
