javascript代码：

    <script src="js/move.js"></script>
    <script>
    var Car = document.getElementsByClassName(‘car‘)[0];//运动条
    var oPic = document.getElementById(‘pic‘);
    var aPicli = oPic.getElementsByTagName(‘li‘);//图片序列
    var otext = document.getElementById(‘text-list‘);
    var otextli = otext.getElementsByTagName(‘li‘);//文字序列
    var index = 0;
    for(var i=0;i<otextli.length;i++){
        otextli[i].index = i;
        otextli[i].onclick = function(){
            var lastIndex = index;
            var nowLeft = this.index*229+15;
            var left = 1146;
            index = this.index;
            //运动条动画
            move( Car , "left" , nowLeft , 20 );

            if ( index > lastIndex )
            {
                left = -left;
            };
            aPicli[index].style.left = -left+‘px‘;
            //移出图片动画
            move( aPicli[lastIndex] , ‘left‘ , left , 50 );
            //移入图片动画
            move( aPicli[index] , ‘left‘ , 0 , 50 );
