How can I link an object to a variable using a select tag in Aurelia with Typescript?

After successfully populating a select tag with options from a static array of objects in JSON, each option set to the object id, I encountered a new challenge.

tvs: any[] = [
        { "id": 1, "ip": "11.11.11.111", "port": "8080", "name": "tv 1" },
        { "id": 2, "ip": "11.11.11.111", "port": "8080", "name": "tv 2" },
        { "id": 3, "ip": "11.11.11.111", "port": "8080", "name": "tv 3" },
        { "id": 4, "ip": "11.11.11.111", "port": "8080", "name": "tv 4" },
        { "id": 5, "ip": "11.11.11.111", "port": "8080", "name": "tv 5" },
        { "id": 6, "ip": "11.11.11.111", "port": "8080", "name": "tv 6" }
    ];

In my HTML file, selecting an object simply displays its name:

<div class="col-md-6 col-lg-6">
     <label>Which tv do you want to alter?</label>
     <select class="form-control">
          <option repeat.for="tv of tvs" value="${tv.id}">${tv.name}</option>
     </select>
</div>

However, I now aim to display additional information dynamically by binding the selected object to another div when clicked. How can I achieve this feature?

Answer №1

To enable binding of models on option elements in a select, Aurelia offers the model.bind feature. Here's an example implementation:

<div class="col-md-6 col-lg-6">
   <label>Choose which TV to modify</label>
   <select class="form-control" value.bind="selectedTV">
      <option repeat.for="tv of tvs" model.bind="tv">${tv.name}</option>
   </select>
</div>
<div if.bind="selectedTV">
  Information for TV ${selectedTV.name}:<br>
  IP: ${selectedTV.ip}<br>
  etc...
</div>
