我的任务
分享touch事件滑动图片
问题比较模糊，标题不好描述，直接上代码，请问有人知道解决吗？
css代码：
* {
margin:0;
padding:0;
}
body {
font-size:12px;
font-family:宋体,arial, helvetica, sans-serif;
color:#282828;
margin:0 auto;
}
.apply {
margin-top: 20px;
overflow: hidden;
width:1000px;
border:1px solid yellow;
margin-left:100px;
}
.apply_nav{
position: relative;
width: 996px;
float: left;
height: 252px;
overflow: hidden;
border:1px solid green;
}
.apply_w {
position: absolute;
margin-top: 22px;
float: left;
border:1px solid red;
}
.apply_array {
width: 198px;
float: left;
height: 212px;
border: #cdcdcd 1px solid;
padding-top: 16px;
}
html 代码：
<div>
<div class="apply">
<div class="apply_nav">
<div class="apply_w">
<div class="apply_array" id="inp">
<div class="apply_img"><img src="imgs/sinaminiblog.gif"></div>
</div>
<div class="apply_array">
<div class="apply_img"><img src="imgs/kaixin001.gif"></div>
</div>
<div class="apply_array">
<div class="apply_img"><img src="imgs/renren.gif"></div>
</div>
<div class="apply_array">
<div class="apply_img"><img src="imgs/baiducang.gif"></div>
</div>
<div class="apply_array">
<div class="apply_img"><img src="imgs/qq.gif"></div>
</div>
<div class="apply_array">
<div class="apply_img"><img src="imgs/qqshuqian.gif"></div>
</div>
<div class="apply_array">
<div class="apply_img"><img src="imgs/qqzone.gif"></div>
</div>
<div class="apply_array">
<div class="apply_img"><img src="imgs/sinavivi.gif"></div>
</div>
<div class="apply_array">
<div class="apply_img"><img src="imgs/sohubai.gif"></div>
</div>
<div class="apply_array">
<div class="apply_img"><img src="imgs/douban.gif"></div>
</div>
<div class="apply_array">
<div class="apply_img"><img src="imgs/zhuaxia.gif"></div>
</div>
<div class="apply_array">
<div class="apply_img"><img src="imgs/gmail.gif"></div>
</div>
<div class="apply_array">
<div class="apply_img"><img src="imgs/delicious.gif"></div>
</div>
</div>
</div>
</div>
</div>
js 代码：
$(function() {
$li1 = $(".apply_nav .apply_array"); //获取到里面每一个div
$window1 = $(".apply .apply_w"); //获取包裹最里面div的大div
$window1.css("width", $li1.length*200); //设置包裹图片的外层div的宽度等于 图片的张数*每张图片的宽度 = 外层div总宽度;
$window1.on({
touchstart: function(e){
var el=$(this);
var os = el.offset();
dx =e.originalEvent.targetTouches[0].pageX-os.left ; //e.originalEvent.targetTouches[0].pageX 鼠标位置 os.left向左边偏移量
$(document).on('touchmove.drag', function(e){
el.offset({ left: e.originalEvent.targetTouches[0].pageX-dx});
});
},
touchend: function(e){ $(document).off('touchmove.drag'); }
});
});
我的运行效果图：
鼠标滑上带图片的div是可以左右拖动的。但是到第一张和最后一张居然也可以拖动。
不知道怎么解决，有人知道吗，怎么样让他在第一张图片的时候不能往左移了，最后一张不能往后移

您好，按照您给的代码改动了下，但是还是会有点问题，当下面没有图片了也可以滑动。

这个是我之前自己写的一个移动端手机触屏滑动效果的banner。你可以参考下看对你有没有帮助不！
