使用VueJ添加动态输入字段

标签： html laravel vue.js vuejs2 dynamic-forms

我正在使用Laravel 5.7和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，我有一个引导模版来创建和更新我的发票。我有2个分布式数据库表，一个用于TicketInvoice，另一个用于TicketInvoiceItems。...TicketInvoiceItems是一个数组，因为TicketInvoice有很多TicketInvoiceItems。

我的<script>标签，这是所有TicketInvoice字段：

<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。

<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：

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

<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：

<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>
