解决方案 »

  1.   

      if(startMove)
    {
                        startMove(0);
    }else
    {
                        startMove(-100);
    }怎么看 怎么不顺眼
      

  2.   

     var startMove1 = true;
            window.onload=function(){
                var oDiv1=document.getElementById('div2');
                oDiv1.onclick=function()
                {
                    if(startMove1)
                    {
                        startMove1 = false;
                        startMove(0);
                    }else
                    {
                        startMove1 = true;
                        startMove(-100);
                    }
                }        }
            //创建运动框架
    覆盖上面
