在 Vuejs 的数据中使用计算属性
如何在数据中使用计算属性或通过总线发出它?
How can I use a computed property in the data or emit it via bus?
我有以下 vue 实例,但 myComputed 始终未定义,但 computedData 工作正常.
I have the following vue instance, but myComputed is always undefined but computedData is working correctly.
var vm = new Vue({
data(){
return{
myComputed: this.computedData
}
},
computed: {
computedData(){
return 'Hello World'
}
}
})
推荐答案
不幸的是,由于组件创建时间问题,无法在数据中使用计算属性:数据在计算属性之前求值.
Unfortunately, it is impossible to use computed property in data because of component creation timing: data evaluates Before computed properties.
