我已将数据和轴位发送给数组(mySplitDays [splitDayIndex] = splitDay),但我有一个错误...
components: { VueCal },
data() {
return {
users:[],
mois:[],
assignments:[],
selectedEvent: {},
showDialog: false,
events: [],//recuperer tache ici
minCellWidth: 400,
minSplitWidth: 150,
splitDays:mySplitDays
};
},
async mounted() {
let response = await axios
.get(`${process.env.***}/users?role=***&active=***`)
let mySplitDays = response.data
for (let splitDayIndex in mySplitDays){
let splitDay= mySplitDays[splitDayIndex]
splitDay.class = splitDay.lastname
splitDay.label = splitDay.lastname
mySplitDays[splitDayIndex]=splitDay
}
}
[Vue警告]:data()中的错误:“ ReferenceError:未定义mySplitDays”

您正在尝试在创建组件时将mySplitDays分配给数据。那时没有变量称为存在。您应该在splitDays中添加一个默认值,例如一个空数组。空数组可能是最好的默认值,因为它具有length属性,因此,如果在模板中的某处使用它,则不会导致问题。然后在已安装的函数内部,将axios的结果分配给数据。
