Question

我想在我的网站上为推荐部分创建一个文本滑块。我发现了两个代码，但我希望有人帮我把它们结合起来。

我想要这个滑块：
codepen 1

但它应该像这样自动改变：
codepen 2

有人可以帮忙吗？提前致谢

Answer 1

我做到了。刚刚添加了JS，它可以找到当前幻灯片，它们的数量并更改已检查的无线电。

HTML：

<div class="slider">

  <input type="radio" name="slider" title="slide1" class="slider__nav"/>
  <input type="radio" name="slider" title="slide2" class="slider__nav"/>
  <input type="radio" name="slider" title="slide3" class="slider__nav"/>
  <div class="slider__inner">
    <div class="slider__contents"><i class="slider__image fa fa-codepen"></i>
      <h2 class="slider__caption">codepen</h2>

JavaScript的：

console.clear();

var slides = $('input[name="slider"]'),
    amount = slides.length,
    number = null,
    currentSlide = null;
console.log(slides);

$(function() {
  setInterval(function () {
    currentSlide = $('input[name="slider"]:checked');
    number = parseInt($(currentSlide).attr('title').slice(5,6));

    console.log('---Current slide');
    console.log(number); //current slide number

    console.log('---Slides array');
    console.log(slides);

    if (number < (amount - 1)) {
      $(slides[number+1]).prop('checked', true);
      console.log('%c---Slide changed to next', 'color: green;');
    } else {
      $(slides[0]).prop('checked', true);
      console.log('%c---Slide changed to 0', 'color: red;');
    }
  }, 2000);
});

使用jQuery。
