        }
    });

How to write the style to take effect

1. :class="[red, gray]" The data attribute in the vue parameter is called

   Copy after login

2. :class="{red : true, gray: true}"

   Copy after login

   The second method can also call the data attribute of the vue parameter. Remember, everything in Vue is data

   new Vue({
       el: '#box',
       data: {
          red: 'red',
          gray: 'gray',
          a: true,
          b: false
    }   
   });

3. :class="json", a simplified version of the second method, the official version

   new Vue({
       el: '#box',
       data: {
           red: 'red',
           gray: 'gray',
           json: {
               a: true,
               b: false
           }
       }
   });

   Copy after login

style

is basically the same as class

1. :style="{}"

1. :style="a"

   new Vue({
       el: '#box',
       data: {
           red: 'red',
           gray: 'gray',
           a: {
               color: 'red',
               backgroundColor: 'gray' //注意复合样式的书写规范
           }
       }
   });
