如何将表单值发送到节点/快递到搜索数据库？

Question

I've got a pre populated form with gps coordinates and I am trying to search a database.

<form>

<mat-toolbar  color="primary">

  <mat-toolbar-row style="justify-content: center;" id="test">  Yonder   </mat-toolbar-row>
 <br>


  <mat-toolbar-row style="justify-content: center;">  <input id="geoSearch" type="text" value="{{coords}}">  </mat-toolbar-row>
  <mat-toolbar-row style="justify-content: center;">    <button type="submit" class="subMitButton" id="location-button" mat-raised-button onclick="window.location.reload();" color="accent"> Locate </button>   </mat-toolbar-row>


</mat-toolbar>
<br>


</form>

and my backend code

app.get('/api/animals',(req, res, next) => {

Animal.find({})
.then(documents => {
  res.status(200).json({
    message: 'success',
    animals: documents
  });
});

How can I send the data from the form to be used in the find query?

Thanks!

Use HttpClient to make the request to your endpoint. In this case you could have something like:

 public response: any; constructor(private readonly http: HttpClient) {} public makeRequest(): void { this.http.get('XXXXXXXXX/api/animals').subscribe((response) => { this.response = response; // console.log(response) }) }

Where XXXXXXXXXXXX is your api base url (probably something like http://localhost:3000)
