如何立即更改字幕onclick的方向 [英] How to change direction of marquee onclick immediately

问题描述

在这里，我试图通过单击方向按钮来更改滚动选取框的方向. 确切的是，在IE和Firefox中，它按预期运行正常，当我单击方向"按钮时，选取框会立即更改其方向.但是在chrome中，这不是预期的，而是当我单击chrome中的选取框时，该选取框完成了其循环，然后开始沿单击的方向流动.

Here i'm trying to change the scrolling marquee direction on click on the direction buttons. Exactly whats happening is that in IE and Firefox its working perfectly as expected, when i click on the direction button, the marquee immediately changes its direction. but in chrome its not expected, instead when i click the marquee in chrome, the marquee completes its cycle and then starts flowing in the direction clicked.

这是我到目前为止所做的代码.

here is the code for what i have done so far.

$(document).ready(function() {
  $('.leftbutton').on('click', function() {
    var marquee = $('.scrollermarquee');
    marquee[0].stop();
    marquee[0].direction = 'left';
    marquee[0].start();
  })

  $('.rightbutton').on('click', function() {
    var marquee = $('.scrollermarquee');
    marquee[0].stop();
    marquee[0].direction = 'right';
    marquee[0].start();
  })
})

.rightbutton {
  background: red;
  padding: 15px;
  right: 20px;
  position: absolute;
  cursor: pointer;
}

.leftbutton {
  background: red;
  padding: 15px;
  position: absolute;
  cursor: pointer;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<span class="leftbutton">&lt;</span>
<marquee class="scrollermarquee">
  <ul>
    <li>
      <div class="views-field views-field-title"><span class="field-content"><a href="#" hreflang="en">test 1</a></span></div>
    </li>
    <li>
      <div class="views-field views-field-title"><span class="field-content"><a href="#" hreflang="en">test 2</a></span></div>
    </li>
    <li>
      <div class="views-field views-field-title"><span class="field-content"><a href="#" hreflang="en">test 3</a></span></div>
    </li>
  </ul>
</marquee>
<span class="rightbutton">&gt;</span>
