Question

我使用带有jQuery UI的工作图片滑块。我可以使用滑块更改图片。现在，我想在一段时间（例如3秒）内自动更改图片。

$(function() {
  var myImages = [
    "img/january/tweet_january_1.svg",
    "img/january/tweet_january_2.svg",
    "img/january/tweet_january_3.svg",
    "img/january/tweet_january_4.svg",
    "img/january/tweet_january_5.svg"
  ];
  $("#start_slider").slider({
    min: 0,
    max: (myImages.length - 1),
    step: 1,
    change: function(event, ui) {
      $('#flask1').attr('src', myImages[ui.value]);
    }
  });
});

.start_heading {
    padding: 2em;
    margin-top: 10em;
    text-align: center;
    font-family: 'Roboto';
    font-size: 1em;
}

#start_slider {
    align-content: center;
    margin-left: 15em;
    margin-right: 15em;
    margin-top: 3em;
    margin-bottom: -10em;
}

<div class="start_heading">
  <h2> Headline</h2>
</div>

<div class="tweets_january">
  <img src="img/january/tweet_january_1.svg" height="" width="" id="flask1" />
  <div id="start_slider"></div>
</div>
