我想将数据从本地存储对象存储到数据库

Question

我想将数据从本地存储对象存储到数据库中

comonent1.html

<form [formGroup]="Add" (ngSubmit)="Submit()">
 <select formControlName="control1">
        <option  value="Select">Select</option>                         
        <option  value="value1">value1</option>                         
        <option  value="value2">value2</option>                 
 </select>
<button>Submit</button>
</form>

component1.ts

   Add= this.formbuilder.group({control1:[''])}

   Submit(){
   localStorage.setItem('form-data', JSON.stringify(this.Add.value));
   this.router.navigate(['/component2'])}

component2.ts

    Save(){
    let formValue = JSON.parse(localStorage.getItem('form-data'))}

我不知道如何将数据从本地存储存储到数据库。我想按其ID存储下拉菜单。
