假设我有一个数据数组:
this.data = [
{
id: 101,
firstName: 'Alice',
lastName: 'Smith',
dob: '1995-12-10'
},
{
id: 102,
firstName: 'Reginald',
lastName: 'Wernst',
dob: '1979-10-03'
},
{
id: 103,
firstName: 'Jolanda',
lastName: 'Finnbogadóttir',
dob: ''
}
]
我可以将数据放入卡中,没问题。而且我可以识别出单击的卡,检索id
,然后将其追溯到数据,例如index == 1
,所以我想要的数据是data[index]
或{ id: 102, firstName: 'Reginald', lastName: 'Wernst', dob: '1979-10-03' }
。
但是随后,我希望能够用数据填充表单以对其进行更新。 v-model
应该是什么样?我尝试了各种组合。通常,它会告诉我诸如data
,index
之类的东西或未定义的内容,那么如何获取和返回数据呢?
<v-dialog v-model="data[index]???" persistent>
<v-text-field v-model="id???" readonly></v-text-field>
<v-text-field label="First Name" v-model="firstName???"></v-text-field>
<v-text-field label="Last Name" v-model="lastName???"></v-text-field>
<v-text-field label="Date of Birth" v-model="dob???"></v-text-field>
<v-btn>Close</v-btn>
</v-dialog>
答案 0 :(得分:3)
value
上的v-model
或v-dialog
控制可见性,而不是其绑定的特定数据;因此,您需要传递一个属性,该属性在单击卡片时会翻转其值:
本质上:
<script>
export default {
data () {
return {
arrData: [
{
id: 101,
firstName: 'Alice',
lastName: 'Smith',
dob: '1995-12-10'
},
{
id: 102,
firstName: 'Reginald',
lastName: 'Wernst',
dob: '1979-10-03'
},
{
id: 103,
firstName: 'Jolanda',
lastName: 'Finnbogadóttir',
dob: ''
}
],
dialog: false,
index: null
}
},
methods: {
clickCard (index) {
this.index = index
this.dialog = !this.dialog
}
}
}
</script>
以及您的模板:
<template>
<v-dialog v-model="dialog" persistent>
<v-text-field v-model="arrData[index].id" readonly></v-text-field>
<v-text-field label="First Name" v-model="arrData[index].firstName"></v-text-field>
<v-text-field label="Last Name" v-model="arrData[index].lastName"></v-text-field>
<v-text-field label="Date of Birth" v-model="arrData[index].dob"></v-text-field>
<v-btn>Close</v-btn>
</v-dialog>
</template>
