Vue跑马灯简单案列

套在自己的vue模板里面即可

    <div v-if="this.content" class="marquee-container" ref="marqueeContainer">
    <span :class="{ 'marquee-text': true, 'marquee-move': shouldMove }" ref="scrollingText" v-if="this.showResult">
      {{ content }}
    </span>
    </div>

content是显示的内容，shouldMove是否滚动(如果大于了文本框才滚动，否则禁止不懂)，showResult是否显示滚动条

  data() {
    return {
      content: '',
      shouldMove: true,
      showResult: false,
    }
  },
