关于javascript中的clearInterval停止不了的问题！！！急~
我崩溃了，为什么clearInterval之后，timer仍然在继续！！！？？？？
关键在这一行。
我已经输出了，而且AdSwitch.thetimer_也是null，但是为什么autochange 仍然在继续？？？
达人求解！！！！！搞了半天了搞不订了！！！！！！

autochange : function() {
AdSwitch.traceinfo( "!change timer " + AdSwitch.thetimer_ + "times = " + (++test));
if (!AdSwitch.thetimer_) {
return;
}
/// 为什么这个一直在继续？？？？？AdSwitch.thetimer_已经是null了阿！！！！！！！！！！！！！！！！
}

[解决办法]
window.clearInterval(AdSwitch.theTimer_);
AdSwitch.thetimer_ = window.setInterval( "AdSwitch.autochange() ", AdSwitch.timeinterval_);
这就是问题所在？拼错大小写？
如果就是这个原因，楼主应该面壁了~~~我只花了2分钟就找到错误了~~~
