javascript - Angular 8 : Reactive Form Automap and PatchValue Set Member data

Question

有没有一种简单的方法可以用自动映射器修补 Angular 表单？我想上课，并将完全相同的成员名称放入表格中。公司形式多，我宁愿不写，尽量避免重复编码(干货原则)等

this.editAddressForm.patchValue({
     'streetNumber':  this.addressMailingData.streetNumber,
     'predirectional':  this.addressMailingData.predirectional,
     'streetName':  this.addressMailingData.streetName,
     'streetType':  this.addressMailingData.streetType,
     'postdirectional':  this.addressMailingData.postdirectional,
     'city': this.addressMailingData.city,
     'state': this.addressMailingData.state,
     'postalCode':  this.addressMailingData.postalCode

尝试的解决方案:这样做会导致以下错误

this.editAddressForm.patchValue(this.addressMailingData);

Error: Argument of type 'string' is not assignable to parameter of type '{ [key: string]: any; }'

Answer 1

如果表单模型和数据想要具有相同值的补丁对象，那么试试这个。

this.editAddressForm.patchValue(this.addressMailingData);
