更新時(shí)間：2017年02月27日 17:06:25 作者：秋荷雨翔

本文主要介紹了js實(shí)現(xiàn)圖片左右滾動(dòng)效果的實(shí)例，具有很好的參考價(jià)值，下面跟著小編一起來(lái)看下吧

需求：頁(yè)面顯示教師信息列表，列表中每一條數(shù)據(jù)顯示圖片滾動(dòng)插件，每張圖片的長(zhǎng)寬及長(zhǎng)寬比例各不相同。

前提條件：美工把靜態(tài)頁(yè)面寫好

HTML代碼：

@using Models;
@{
 List<cms_content> teacherList = ViewData["teacherList"] as List<cms_content>; //春雨樹(shù)頻道
 PagerModel pager = ViewData["pager"] as PagerModel;
}
<div class="teacherteam_box">
 <h1>教師團(tuán)隊(duì)</h1>
 @foreach (cms_content teacher in teacherList)
 {
  <div class="teacher_box">
   <div class="teacher_img fl">
    <img src="~/Theme/images/t1.png" />
   </div>
   <div class="teacher_infor fl">
    <h2>@teacher.title</h2>
    <p>
     @teacher.description
    </p>
    <div class="products_box">
     <div class="products_pre">
      <img src="~/Theme/images/left.png" />
     </div>
     <div class="products_next">
      <img src="~/Theme/images/right.png" />
     </div>
     <div class="div-imgbox">
      <ul>
       @foreach (Tuple<string, string> item in teacher.imgList)
       {
        <li>
         <img alt="@item.Item1" src="@item.Item2" />
        </li>
       }
      </ul>
     </div>
    </div>
   </div>
   <div class="clear"></div>
  </div>
 }
 <div class="page_box">
  <span>共@(pager.totalRows)條信息</span>
  <a href="javascript:void(0);" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" onclick="teacherPage(this,1)">首頁(yè)</a>
  <a href="javascript:void(0);" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" onclick="teacherPage(this,2)">上一頁(yè)</a>
  <a href="javascript:void(0);" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" ><i>@pager.page</i><b>/@pager.pageCount</b>頁(yè)</a>
  <a href="javascript:void(0);" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" onclick="teacherPage(this,3)">下一頁(yè)</a>
  <a href="javascript:void(0);" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" onclick="teacherPage(this,4)">尾頁(yè)</a>
 </div>
</div>

JS代碼：

<script type="text/javascript">
 var _lock = false;
 $(function () {
  teacherPage(null, null);
 });//end $
 //教師團(tuán)隊(duì)
 //flag=1首頁(yè)，2上一頁(yè)，3下一頁(yè)，4尾頁(yè)
 function teacherPage(obj, flag) {
  var totalPage = 1;
  var page = 1;
  if (obj) {
   page = parseInt($(obj).parent().find("i").text());
   totalPage = parseInt($(obj).parent().find("b").text().replace("/", ""));
  }
  if (flag == 1) { page = 1; }
  if (flag == 2 && page > 1) { page = page - 1; }
  if (flag == 3 && page < totalPage) { page = page + 1; }
  if (flag == 4) { page = totalPage; }
  $.ajax({
   type: "GET",
   url: "@Url.Content("~/")home/teachers?t=" + new Date().valueOf(),
   data: { page: page },
   success: function (data) {
    $('#teachers').html(data);
    sliderImg();
   }
  });
 }
 //滾動(dòng)圖片
 function sliderImg() {
  $(".products_next").click(function () {
   if (_lock) return;
   _lock = true;
   var ul = $(this).parent().find("ul");
   if (!canSlider(ul)) { _lock = false; return; }
   var liFirst = ul.find("li:first");
   var margin = liFirst.width() + 15;
   var speed = margin * 3;
   liFirst.animate({
    marginLeft: 0 - margin
   }, speed);
   setTimeout(function () {
    liFirst.remove();
    ul.append("<li>" + liFirst.html() + "</li>");
    _lock = false;
   }, speed);
  });
  $(".products_pre").click(function () {
   if (_lock) return;
   _lock = true;
   var ul = $(this).parent().find("ul");
   if (!canSlider(ul)) { _lock = false; return; }
   var liLast = ul.find("li:last");
   var margin = liLast.width() + 15;
   var speed = margin * 3;
   ul.prepend("<li style='margin-left:-" + margin + "px; '>" + liLast.html() + "</li>");
   var liFirst = ul.find("li:first");
   liFirst.animate({
    marginLeft: 0
   }, speed);
   setTimeout(function () {
    liLast.remove();
    _lock = false;
   }, speed);
  });
 }
 //判斷圖片是否可以滾動(dòng)
 function canSlider(ul) {
  var width = 0;
  ul.find("li").each(function () {
   var li = $(this);
   width = width + li.width() + 15;
  });
  if (width <= 710) {
   return false;
  }
  return true;
 }
</script>
