代码介绍(其实就是通过字符串截取加定时拼接完成的,我相信有时间都能琢磨出来,来这里就是为了省事)

上vue页面代码:

<template>
  <div id='App'>
    <h2>{{text}}<span ref="fou" class="fousdis">{{'_'}}</span></h2>
  </div>
</template>
<script>
export default {
  name: 'App',
  data() {
    return {
      initialText: '这是一个打字教程打字教程，。，。，777',
      index: 0,
      text: ''
    }
  },
  mounted() {
    setInterval(() => {
      this.autoTyping()
      var tim = setInterval(() => {
              this.$refs.fou.classList.toggle('fousdis')
               if (this.index === this.text.length) {
                    clearInterval(tim)
                      }
            }, 150)
    }, 300)
  },
  methods: {
    autoTyping() {
      this.index++
      this.text = this.initialText.slice(0, this.index)
      // this.index = this.text.length === this.initialText.length ? 0 : this.index  //实现循环打字
    }
  }
}
</script>
<style >
.fousdis{
  display: none;
}
</style>

老规矩:复制粘贴那去看效果
