jquery:创建幻灯片轮播

jquery: Creating a slide carousel

本文关键字：幻灯片 创建 jquery      更新时间：2023-09-26

我正在尝试使用Jquery创建图像和文本的简单轮播。我想通过更改每个图像的边距 - 右边距来做到这一点，问题是当它到达UL的末尾时是空的。如何创建循环情况？我想我可能会用"replaceWith"来做到这一点，但它并没有真正发生。谢谢。

.html： 

<div class="slider">
  <ul>
    <li class="continer" id="1">
       <div class="text_body">
 <h2> text </h2>
      <p>text</p>
   </div>
    <div class="play"><img src="play.png" alt=""></div>
 <img src="img/01 (8).jpg" alt="">

   </li>

     <li class="continer" id="2">
          <div class="text_body">
         <h2> text </h2>
        <p>text</p>

     </div>
    <div class="play"><img src="play.png" alt=""></div>
   <img src="img/01 (7).jpg" alt="">

       </li>
     <li class="continer" id="3">
    <div class="text_body">
   <h2> text </h2>
    <p>text</p>

   </div>
   <div class="play"><img src="play.png" alt=""></div>
    <img src="img/01 (6).jpg" alt="">
      </li>

      </ul>
        </div>

.css： 

   .slider {
        width: 620px;
        overflow: hidden;
        margin: 0px auto;

        }
        ul {
        width: 1882px;
        height: 260px;
        list-style-type: none;
        margin-right: 0px;
        padding-right: 0px;


        }
        li {
        width: 620px;
        height: 260px;
        display: inline-block;


        }
        .text_body {
        float: left;
        width: 180px;
        margin-left: 10px;
        }
        .continer img {
        width: 410px;
        height: 250px;


        }

        .text_body h2 {
            margin-bottom: 5px;

        }
        .play img {
        width: 60px;
        height: 60px;
        position: fixed;
        margin-top: 183px;
        margin-right: 336px;
        }

jquery： 

        var sliderInt = 1, sliderNext = 2,
        count = $(".continer").size();
        $(function() {

        $(".continer#1").animate({
            marginRight: "-620px",
          }, 1500 );
        startSlider(sliderInt);  function startSlider(sliderNext) {
            count = $(".continer").size();
            console.log(count);

            loop = setInterval(function() {
                $(".continer#" + sliderNext).animate({
            marginRight: "-620px",
          }, 1500 );


                sliderInt = sliderNext;
                sliderNext = sliderInt + 1;
                if (sliderNext > count -1) {

                    $(".continer#" + sliderInt).replaceWith($(".continer#" + sliderNext));



                }


            }, 3000);

        }

jQuery(document).ready(function ($) {
  $('#checkbox').change(function(){
    setInterval(function () {
        moveRight();
    }, 3000);
  });
    var slideCount = $('#slider ul li').length;
