JQ代码：
<script type="text/javascript">
$(document).ready(function(){
var cca = $(".move-line");
/* 绑定鼠标左键按住事件 */
cca.bind("mousedown",function(event){
/* 获取需要拖动节点的坐标 */
var offset_x = $(this)[0].offsetLeft;//x坐标
var offset_x2 = $("html").width()-offset_x;//x坐标
//var offset_y = $(this)[0].offsetTop;//y坐标
/* 获取当前鼠标的坐标 */
var mouse_x = event.pageX;
//var mouse_y = event.pageY;
/* 绑定拖动事件 */
/* 由于拖动时，可能鼠标会移出元素，所以应该使用全局（document）元素 */
$(document).bind("mousemove",function(ev){
/* 计算鼠标移动了的位置 */
var _x = ev.pageX - mouse_x;
//var _y = ev.pageY - mouse_y;
var now_x1 = (offset_x + _x )

}
//var now_y = (offset_y + _y ) + "px";
/* 改变目标元素的位置 */
$(".img").css({

width:now_x2});
$(".move-line").css({
//top:now_y,
left:now_x1
});
});
});
/* 当鼠标左键松开，接触事件绑定 */
$(document).bind("mouseup",function(){

})
</script>
一阶段项目 总结 之 两张图片对比 手写 jquery 也可以使用beer slider 插件
