问题描述
我正在使用Laravel 5.7& VueJs 2.5.* ...
I'm using Laravel 5.7 & VueJs 2.5.*...
我知道如何动态添加输入字段，但是对于我的应用程序，我不知道该怎么做.我有"TicketInvoice.Vue"，在该页面中，我有一个引导程序模版来创建&更新我的发票.我有2个简单的DB表，一个用于TicketInvoice，另一个用于TicketInvoiceItems....TicketInvoiceItems是一个数组，因为TicketInvoice有很多TicketInvoiceItems.
I know how to add input fields dynamically but for my app i don't understand how to do. I have 'TicketInvoice.Vue', In that page i have a bootstrap modal to create & update my invoices. I have 2 saperate DB table one for TicketInvoice and other for TicketInvoiceItems.... TicketInvoiceItems is an array because a TicketInvoice has many TicketInvoiceItems.
我的<script>标签，这是所有TicketInvoice字段:
My <script> tag, Here is all TicketInvoice fields:
<script>
export default {
data() {
return {
ticketInvoices: {},
form: new Form({
id: "",
vendor_id: "",
ticket_invoice_no: "",
ticket_invoice_date: "",
ticket_invoice_fares_total: "",
ticket_invoice_taxes_grand_total: "",
ticket_invoice_grand_total: "",
ticket_invoice_grand_total_words: "",
ticket_invoice_terms: "",
})
};
},
</script>
TicketInvoiceItems = Data，我希望动态添加其字段.
TicketInvoiceItems = Data which i want their field to be added dynamically.
<script>
export default {
data() {
return {
form: new Form({
ticketInvoiceItems: [{
ticket_invoice_id: '',
passenger_name: '',
ticket_no: '',
flight_no: '',
departure_date: '',
sector: '',
fares: '',
tax_SB: '',
tax_SRP: '',
tax_YQ: '',
tax_RG: '',
tax_PK: '',
tax_YR: '',
tax_SF: '',
tax_PTT: '',
tax_OAS: '',
tax_PSF: '',
tax_PB: '',
tax_OAD: '',
total_tax_breakup: '',
sub_total: ''
}]
};
},
</script>
这是我的HTML代码:

推荐答案
您需要添加一个包含所有所需字段的模板.假设它们都是文本字段
You need to add a template that has all the fields you need. Let's assume they are all text-fields
<script>
export default {
data() {
return {
formFields: [
"passenger_name",
"ticket_no",
"flight_no",
"departure_date",
"sector",
]
...
}
}
}
然后，您现在可以将字段动态添加到表单中，如下所示:
Then you can now dynamically add the fields into the form like so:
<td v-for="(fieldName, pos) in formFields" :key="pos">
<input v-model="form[fieldName]" size="40" type="text" :name="fieldName" class="table-control form-control" :class="{ 'is-invalid': form.errors.has(fieldName) }">
<has-error :form="form" :field="fieldName"></has-error>
</td>
