修复一下，百度经验网可查
多谢各位帮忙，已经解决了
最后少了+号
var repeat= "moveElement("+elementID+","+final_x+","+final_y+","+interval+")";
setTimeout要改为这样
//var repeat= "moveElement("+elementID+","+final_x+","+final_y+","+interval+")";
movement=setTimeout(function(){moveElement(elementID,final_x,final_y,interval)},interval);
