angular制作一个添加患者的方法无法新增患者。
我用angular制作了一个增加患者的一个方法，数据储存在一个数组中，当我在网页输入数据时，显示不出来我新增的数据（不确定有没有把新数据存在数组里）。
app.component.ts：
```typescript
import { Component } from '@angular/core';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
title = 'myapp';
Patient = Patient;
patient_IDText:string="";
patient_IDText2:string="";
FirstNameText:string="";
LastNameText:string="";
DateOfBirthText:string="";
GenderText:string="";
PrimaryInsuranceText:string="";
AddressText:string="";
ContactNumberText:string="";
NextOfKinText:string="";
add(){
Patient.push( [
this.patient_IDText2,
this.FirstNameText,
this.LastNameText,
this.DateOfBirthText,
this.GenderText,
this.PrimaryInsuranceText,
this.AddressText,
this.ContactNumberText,
this.NextOfKinText]);
return Patient;
}
}
const Patient: any[]= [
{ Id: "0", FirstName: "Stark", LastName: "Bill", DateOfBirth: "2000/10/11", Gender: "Male", PrimaryInsurance: "Medicare", Address: "ddadsdasd", ContactNumber: "1338872818738", NextOfKin: "weqe" },
{ Id: "1", FirstName: "Shown", LastName: "Jenny", DateOfBirth: "2000/10/11", Gender: "Male", PrimaryInsurance: "Medicare", Address: "ddadsdasd", ContactNumber: "1338872818738", NextOfKin: "weqe" },
{ Id: "2", FirstName: "Geogrge", LastName: "Hash", DateOfBirth: "2000/10/11", Gender: "Male", PrimaryInsurance: "Medicare", Address: "ddadsdasd", ContactNumber: "1338872818738", NextOfKin: "weqe" },
{ Id: "3", FirstName: "Intwre", LastName: "zaiwoo", DateOfBirth: "2000/10/11", Gender: "Male", PrimaryInsurance: "Medicare", Address: "ddadsdasd", ContactNumber: "1338872818738", NextOfKin: "weqe" },
{ Id: "4", FirstName: "Niko", LastName: "baby", DateOfBirth: "2000/10/11", Gender: "Male", PrimaryInsurance: "Medicare", Address: "ddadsdasd", ContactNumber: "1338872818738", NextOfKin: "weqe" }
];
app.component.html：
```html
<body><h1 class="title">patient data</h1>

当我在网页输入数据并点击insert按钮时列表中显示了新的一行但里面没有数据。
请问该怎么解决这个问题？
