推荐答案

你好，

我不确定，但是听起来好像slider(?)会生成很多事件?
也许您可以在启动过程时禁用滑块，然后在退出过程之前重新启用它?


还有上面的线...

Hello,

I''m not sure, but it sounds like the slider(?) is generating lots of events?
Maybe you could disable the slider as you start the procedure and re-enable it before you exit the procedure?


Also the line above...

if(p1 ==0 ||p2 ==0 || p ==0)

不应该吗?

Shouldnt that be?

if(p1 ==0 ||p2 ==0 || p3 ==0)
