vue.js click to edit class

This time I will bring you vue.js to click to edit the class. What are the precautions for vue.js to click to edit the class? The following is a practical case, let’s take a look.

Recently, I need to use vue to implement a page for ordering food and selecting product specifications. I need to use vue to dynamically add class names to the clicked elements to make them change color, and delete other classes. As shown in the picture:

I started looking for many methods on the Internet and found that they were not very useful. Finally, I found a good discovery. Record it

html:

    

     
{{guigeName}}
     
规格
     

      {{value.guige_name}}
     
     
口味
     

      {{value.guige_name}}
     
    

   

script:

var guige=new Vue({
    el: '#guige',
    data:{
     guigeSpan:"-1", //控制点亮状态 -1为默认不点亮
     kouweiSpan:"-1", //控制点亮状态 
    },
   methods:{
     guige:function(index){ //当点击时候点亮，同级的span标签删除Class
      this.guigeSpan = index;
     },
     kouwei:function(index){
      this.kouweiSpan = index;
     },
    }
   })
