angular.js - angular select problem

Question

Now I have a problem. The value of Select is obtained remotely. The following is the json returned by the server

When I use ng-options to bind to select, the value of option is in the following format:

Why does it look like number: 1? How can I remove it?
In addition, how do I get the selected value after submitting the form?
Thank you everyone

Answer 1

The first way to write it is like this

<select ng-model="xxx" ng-options="item.name for item in fishBreed track by item.fish_breed_id"></select>

What is taken out from ng-model is the object you selected. Two-way binding will bind the value through item.fish_breed_id

Answer 2

js：$scope.toString = function(){

                               list.id.toString();
                            }

html: <option value="{{toString(x.id)}}" ng-repeat="x in list" ng-bind="x.name"></option>
