• div+css+jQuery图片横向滚动代码(带左右点击按钮)


    首先感谢Blue老师的javascript教程,给了我很多的启发,这是我在看完10 - 定时器的使用 - 2这节视频后,自己试着用jQuery重新改写了一下代码,感觉至少比百度搜出来的那一坨靠谱多了,上代码:

    <!DOCTYPE HTML>
    <html lang="en-US">
    <head>
        <meta charset="UTF-8">
        <title></title>
        <script type="text/javascript" src = "jquery_v1.7.2.js"></script>
        <script type="text/javascript">

    Name:jQuery插件图片左右无缝滚动
    Arguments:
        @leftBtn:向左滚动按钮DOM引用
        @rightBtn:向右滚动按钮DOM引用
        @speed:滚动速度(每次滚动像素数)
    CSS keyed Attribute:
        #noSeamScroll{position:relative;overflow:hidden;}
        #noSeamScroll ul{position:absolute;}    
        #noSeamScroll ul li {float:left;}    
    ===============*/
        $.fn.extend({noSeamScroll:function (leftBtn,rightBtn,speed){
            var timeFlag = speed = speed || 4;;
            var timer = null;
            var _this = this;//把this重新保存在一个私有变量里面,以防止setInterval误把this指向了window
            this.oUl = $("ul",this);
            this.oUl.html(this.oUl.html() + this.oUl.html());//把li复制一份
            this.oLis = $("ul li",this);//之后再变量保存li的全部节点
            this.oUl.width(this.oLis.eq(0).outerWidth(true)*this.oLis.length + "px");
            var fnMove = function (){
                $("ul",_this).css("left",function (){
                    if ($(this).position().left > 0){//这里的this指的是$("ul",element)
                        return -$(this).outerWidth(true)/2 + "px";
                    }

                        return "0px";
                    }
                    return $(this).position().left  + timeFlag + "px";
                })
            }
        
            timer = setInterval(fnMove,30);
            
            this.mouseover(function () {clearInterval(timer);});
            this.mouseout(function () {timer = setInterval(fnMove,30)});

        });
    
        //test
        $("#noSeamScroll").noSeamScroll($("#leftArr"),$("#rightArr"),2);
