vue3数据变化和数据解包

在vue3中和vue2中数据会有所不一样,不一样的地方在于数据的写法和变化

在vue3中数据的变化是需要用到reactive的

在父级中引入

inport{ toRefs, reactive} from "vue

数据:

set(){

  const  data=reactive({

    resource:[

      

 {                     _id:"1",                     title:"新闻1",                     description:"新闻新闻",                     type:"video",                     link:""                 },                 {                     _id:"2",                     title:"新闻2",                     description:"新闻新闻",                     type:"video2",                     link:""                 },                 {                     _id:"3",                     title:"新闻3",                     description:"新闻新闻",                     type:"video3",                     link:""                 },                 {                     _id:"4",                     title:"新闻4",                     description:"新闻新闻4",                     type:"video",                     link:""                 },                 {                     _id:"5",                     title:"新闻5",                     description:"新闻新闻5",                     type:"video",                     link:""                 },                 {                     _id:"6",                     title:"新闻6",                     description:"新闻新闻6",                     type:"video",                     link:""                 },                 {                     _id:"7",                     title:"新闻7",                     description:"新闻新闻7",                     type:"video",                     link:""                 }

    ]

  })

  return{ .../toRefs(data)}

}

声明:

  1.数据是需要用到reactive的  完整的写法就是  import  {reactive} from 'vue'

  2.数据解包:是需要用到toRefs  完整的写法就是 import{ toRefs} from "vue"

  3.   .../toRefs(data)是解包数据的   因为上述的写法在没有使用解包.../toRefs(data)的时候。调用数据是写成2data.resource,当解包之后可以直接获取数据resource
