Working with multidimensional arrays in AngularJS using ng-repeat

I have noticed that there are numerous inquiries on this subject that have already been resolved.

As someone who is new to Angular, I am struggling to grasp the concept of how the {{variable}} notation actually functions.

When using an API, the response typically looks like this:

data : "MTS-K"
license : "CC BY 4.0 -  https://creativecommons.de"
ok : true
stations : Array(3)
0 : {id: "XXX", name: "XXX", brand: "XXX", street: "XXX", place: "YYY"}
1 : {id: "XXX", name: "XXX", brand: "XXX", street: "XXX", place: "YYY"}
2 : {id: "XXX", name: "XXX", brand: "XXX", street: "XXX", place: "YYY"}
__proto__ : Object

The TypeScript code I have written to retrieve this data appears as follows:

this.GasStationProvider.getStations(this.location.lat, this.location.lng).subscribe(
gasStation => {
    this.gasStation = gasStation.stations;
});

While my HTML code is structured in this manner:

<p>{{gasStation.stations}}</p>

When rendered, the HTML displays:

[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

If you could provide guidance on how I can individually display each line within the station array or direct me to a helpful tutorial, it would be greatly appreciated.

Thank you for your assistance

Answer №1

If you have an array of objects, you can utilize the ng-repeat directive to loop through each object and even iterate through every field in the object.

/*Use ng-repeat to go through all objects in gasStation array*/

<p ng-repeat="station in gasStation">//Looping through the stations array

  //Using a nested loop to iterate through each field of the object: {id: "XXX", name: "XXX",..}

  <li ng-repeat="(key, value) in station">//Iterating through each field within the object.
    {{key}} : {{value}}
  </li>

</p>

Answer №2

When working with TypeScript in Angular 2+, it's important to use *ngFor and not ng-repeat, which is specific to AngularJS.

*ngFor functions similar to an iterator in a for loop:

//example pseudocode

for( item in array )
   //using interpolation
   {{ item.value }}

If you encounter the issue of receiving Object object, try accessing a value within your array, like so:

<p>
    {{gasStation.stations.name}}
</p>

Additionally, consider using console.log to inspect your object and understand how it is being passed through.
