javascript setTimeOut方法 实现滑动效果（类似2D加速）

 

setTimeOut方法跟参数如下：

function test(str,str2) { alert(str+" "+str2); setTimeout("test('"+str+"','"+str2+"');",1000); } var hello = "hello，你好！"; test(hello,"Mygirl")

滑动效果代码如下：

var focusMovePosition = [[438,425],[554,425]];var curFocusTopTimeout=0;var curMovePosition =438;var endMovePosition = 0;function funKeyPressLeft(){ focusNumber --;if(focusNumber < 0)focusNumber = 1;//$("focus").style.webkitTransitionDuration = "300ms"; //$("focus").style.left = focusMovePosition[focusNumber][0]; if(438 == focusMovePosition[focusNumber][0]){ $("focus").style.left = focusMovePosition[focusNumber][0] + "px"; } endMovePosition = focusMovePosition[focusNumber][0]; fnMoveFocus();}function fnMoveFocus(){if(curFocusTopTimeout > 0) clearTimeout(curFocusTopTimeout) ;if(curMovePosition==endMovePosition){ }else{ 　　　　　　　　　　　　　　//下面这句是实现滑动的代码 curMovePosition += Math.ceil(Math.abs(endMovePosition - curMovePosition)/3) * ((endMovePosition - curMovePosition)/Math.abs(endMovePosition - curMovePosition)) ; funSetCurTop() ; curFocusTopTimeout = setTimeout(fnMoveFocus,30) ; } }function funSetCurTop(){ $("focus").style.left = curMovePosition +"px";}
