This article mainly introduces the basic usage of v-bind in VUE. The content is quite good. I will share it with you now and give it as a reference.

I have learned the basic usage of v-bind in the past two days, so I will add a few notes today.

1. v-bind:class (select according to your needs)

1.1

 <style>
.box{
  background-color: #ff0;
}
.textColor{
  color: #000;
}
.textSize{
  font-size: 30px;
}
</style>

<p id="app">
  <span class="box" :class="{&#39;textColor&#39;:isColor, &#39;textSize&#39;:isSize}">我是字</span>
</p>

<script>
　　new Vue({
  　　el: "#app",
　　data:{
  　　isColor:true,
  　　isSize:true
　　}
　　})
</script>
