我一整天都在网上冲浪......帮助。我有Vue.js应用程序。在我的组件中,我将数据数组变量等同于来自服务器的响应。但是当我尝试将一些数据推送到数组时,会出现以下错误:未捕获(在承诺中)TypeError:_this.tasks.push不是函数。我试图注销响应,它返回了这个:
{__ob__: Observer}
8
:
(...)
9
:
(...)
15
:
(...)
__ob__
:
Observer {value: {…}, dep: Dep, vmCount: 0}
get 8
:
ƒ reactiveGetter()
set 8
:
ƒ reactiveSetter(newVal)
get 9
:
ƒ reactiveGetter()
set 9
:
ƒ reactiveSetter(newVal)
get 15
:
ƒ reactiveGetter()
set 15
:
ƒ reactiveSetter(newVal)
__proto__
:
Object
这是我的组件js代码
import User from '../../services/UserService';
export default {
data() {
return {
taskText: '',
tasks: []
}
},
methods: {
createNewTask() {
User.createUserTask(this.taskText).then(response => {
if (response) {
this.tasks.push(response);
this.taskText = '';
Materialize.toast('Task was added', 4000);
}
});
},
markTaskAsDone(taskId) {
User.markTaskAsDone(taskId).then(response => {
if (response) {
this.tasks = this.tasks.filter(task => task.id !== taskId);
Materialize.toast('Task was completed', 4000);
}
});
}
},
mounted() {
const toast = Materialize.toast('Loading...');
User.getUserTasks().then(response => {
if (response) {
this.tasks = response;
toast.remove();
console.log(response);
}
});
}
}
我做错了什么?
答案 0 :(得分:1)
我可以做的唯一推断是response
在此均衡上不是数组。
this.tasks = response;
