這篇文章主要為大家詳細介紹了基于jQuery實現(xiàn)滾動切換效果,具有一定的參考價值，感興趣的小伙伴們可以參考一下

仿鋒利的Jquery案例做的一個滾動切換效果，供大家參考，具體內(nèi)容如下

效果如下圖:

前臺HTML代碼如下:

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

  <script type="text/javascript" src="script/jquery-1.8.3.js"></script>
  <script type="text/javascript">
    $(function () {
      var page = 1;
      var i = 4;
      var $v_trends = $("#view_menu_trends").find("li");
      $v_trends.eq(0).addClass('currentTrends');//默認第一個點選中
      $(".next").click(function () {
        var $parent = $("#view_menu");
        var $v_content = $("#view_content");//外圍width
        var $v_show = $("#view_content_fixed");//

        var v_width = $v_content.width();
        var len = $v_content.find('li').length;
        var page_count = Math.ceil(len / i);//所有的圖片數(shù)/版面數(shù)=總頁數(shù)
        if (!$v_show.is(":animated")) {
          if (page == page_count) {
            $v_show.animate({ left: '0px' }, 'slow');//如果超過總頁數(shù) 那么就跳回第一頁
            page = 1;
          } else {
            $v_show.animate({ left: '-=' + v_width }, 'slow');
            page++;
          }
          $v_trends.removeClass('currentTrends').eq(page - 1).addClass('currentTrends');
        }
      });
      $(".pre").click(function () {
        var $parent = $("#view_menu");
        var $v_content = $("#view_content");//外圍width
        var $v_show = $("#view_content_fixed");//
        var v_width = $v_content.width();
        var len = $v_content.find('li').length;
        var page_count = Math.ceil(len / i);//所有的圖片數(shù)/版面數(shù)=總頁數(shù)
        if (!$v_show.is(":animated")) {//判斷是否是動畫狀態(tài)
          if (page == 1) {
            $v_show.animate({ left: '-=' + (page_count - 1) * v_width + "px" }, 'slow');//到了第一頁那么跳轉(zhuǎn)到最后一頁
            page = page_count;
          } else {
            $v_show.animate({ left: '+=' + v_width }, 'slow');
            page--;
          }
          $v_trends.removeClass('currentTrends').eq(page - 1).addClass('currentTrends');

RollControl.css代碼如下:

body {
  margin: 0px;
  padding: 0px;
}

#view_menu {
  width: 600px;
  height: 30px;
  line-height: 30px;
  cursor: default;
}

#view_menu_title {
  float: left;
  font-family: 'Microsoft YaHei';
  width: 150px;
  text-align: center;
}

#view_menu_trends {
  float: left;
  line-height: 30px;
  color: #99CC99;
  font-size: 10px;
}

.currentTrends {
  color: #009933;
}

#view_menu_trends ul {
  list-style: none;
  margin: 0px;
  padding: 0px;
}

#view_menu_trends ul li {
  text-align: center;
  float: left;
  width: 15px;
}

#view_menu_control {
  float: left;
  width: 100px;
  height: 30px;
  text-align: center;
}

#view_menu_control img {
  width: 25px;
  height: 25px;
  line-height: 30px;
  cursor: pointer;
}

#view_content {
  width: 548px;
  height: 178px;
  position: relative;
  overflow: hidden;
  border: 1px solid #CCCCCC;
}

#view_content_fixed {
  position: absolute;
  width: 2500px;
}

#view_content_fixed img {
  cursor: pointer;
}

#view_content ul {
  margin: 0px;
  position: absolute;
  padding: 0px;
}

#view_content ul li {
  margin: 0px;
  padding: 0px;
  float: left;
  padding: 8px;
  list-style: none;
  display: inline;
}

.view_content_fixed下的SPAN標簽是為了加標題的
