Vue的新手。
使用vue-property-decorator
,并尝试使用vue-class-component
。
根据github(https://github.com/kaorun343/vue-property-decorator),data
对象在类中明确声明,例如ecosystem
:
import {Component, Vue} from 'vue-property-decorator';
@Component({
components: {}
})
export default class HelloWorld extends Vue {
ecosystem: [
{
text: 'vuetify-loader',
href: 'https://github.com/vuetifyjs/vuetify-loader'
},
{
text: 'github',
href: 'https://github.com/vuetifyjs/vuetify'
},
{
text: 'awesome-vuetify',
href: 'https://github.com/vuetifyjs/awesome-vuetify'
}
]
}
代替
data() {
return {
ecosystem: ['bla', 'bla', 'bla']
}
}
但是,当我尝试使用它时,出现错误Property or method "ecosystem" is not defined on the instance but referenced during render.
呼叫
created() {
console.log(this.ecosystem)
}
还返回undefined
我想念什么?

查看运行示例:https://codesandbox.io/s/y2nop643xv
像这样声明生态系统:
ecosystem: any = [
{
text: "vuetify-loader";
href: "https://github.com/vuetifyjs/vuetify-loader";
},
{
text: "github";
href: "https://github.com/vuetifyjs/vuetify";
},
{
text: "awesome-vuetify";
href: "https://github.com/vuetifyjs/awesome-vuetify";
}
];
提示,尽量避免使用任何东西,您正在使用打字稿,请使用键入的对象
