前端技术 2023/09/09 JavaScript

首页banner的酷炫效果多来自全屏大图的幻灯片动画，下面提供一种完美兼容的jquery动画特效：全新jquery多点滑动幻灯片——全屏动画animateSlide（代码完全原创）。

直接上代码，把html、css和jquery代码copy到页面上即可呈现完美画面。

html代码如下：

<div class=\"animateSlide\">
  <div class=\"animateSlideImgWrap\">
    <div class=\"animateSlideImgBox present\">
      <p class=\"text1\">亲，这是第一行标题</p>
      <p class=\"text2\">AAAAAAAAAAAAAAAAAAAAA</p>
      <!--<img class=\"img\" alt=\"\" src=\"img/1.png\" />-->
      <div class=\"img\" style=\"width: 500px; height: 390px; background: #ffaeae; opacity: 0.6;\"></div><!-- 实际项目中用上面注释的半透明png图片，目前临时用div代替图片 -->
    </div>
    <div class=\"animateSlideImgBox\">
      <p class=\"text1\">亲，这是一行宣传语</p>
      <p class=\"text2\">BBBBBBBBBBBBBBBBBBBBB</p>
      <!--<img class=\"img\" alt=\"\" src=\"img/2.png\" />-->
      <div class=\"img\" style=\"width: 500px; height: 390px; background: #aeffb2; opacity: 0.6;\"></div><!-- 实际项目中用上面注释的半透明png图片，目前临时用div代替图片 -->
    </div>
    <div class=\"animateSlideImgBox\">
      <p class=\"text1\">亲，这是一个奇迹啊</p>
      <p class=\"text2\">CCCCCCCCCCCCCCCCCCCCC</p>
      <!--<img class=\"img\" alt=\"\" src=\"img/3.png\" />-->
      <div class=\"img\" style=\"width: 500px; height: 390px; background: #aebdff; opacity: 0.6;\"></div><!-- 实际项目中用上面注释的半透明png图片，目前临时用div代替图片 -->
    </div>
  </div>
  <div class=\"animateSlideBtnL\"><</div>
  <div class=\"animateSlideBtnR\"><</div>
</div>

css代码如下：

.animateSlide {width: 100%; height: 390px; position: relative; background: #f5f5f5;}
.animateSlideImgWrap {width: 100%; height: 390px; position: absolute; z-index: 1; overflow: hidden;}
.animateSlideImgWrap .present {display: block;}
.animateSlideImgBox {width: 100%; height: 390px; position: absolute; z-index: 1; display: none;}
.animateSlideImgBox .text1 {font-family: Microsoft YaHei; font-size: 36px; line-height: 1.2em; color: #384cd0; position: absolute; top: 120px; z-index: 3; white-space: nowrap;}

.animateSlideImgBox .img {position: absolute; left: 470px; top: 0; z-index: 2;}
.animateSlideBtnL,
.animateSlideBtnR {
  width: 30px; height: 60px; line-height: 60px; font-size: 20px; font-weight: 700; text-align: center; background: #ddd;
  position: absolute; left: 30px; top: 150px; z-index: 6; cursor: pointer; display: none;
