下面是不懂的
----------------------------------------------------------------
1 onResize=javascript:parent.carnoc.location.reload() //什么意思,没有它可以吗
2 if(self!=top){top.location=self.location;} //什么意思,它的下面没有end if但又没有报错
3 if (switchPoint.innerText==3) //这个判断innerText啥意思
4 IsObjInstalled //起的什么作用
5 document.all("frmTitle").style.display="none" //这个
