从选中的复选框获取数据

Question

I need to get the info from a checked checkbox. What i'm doing is get data from an api and showing as checkbox. Here's a part of my code where also have a validation if at least one coupon is checked:

vm.sendData = function() {
  vm.apiData = couponApi.get({
    idOrder: vm.idOrder
  })
  .$promise
  .then(function(data) {
    for (var i = 0; i < data.Response.length; i++) {
      data.Response[i].Select = vm.all;
    }
    vm.coupons = data.Response;
    vm.combo = data.Response.length > 0;
  });
}

vm.selectAll = function() {
  vm.all = !vm.all;
  vm.coupons.forEach(function(o) {
    o.Select = vm.all;
  })
}

vm.submit = function() {
  var checked = 0;
  vm.coupons.forEach(function(o) {
    if (o.Select === true)
      checked += 1;
  })
  if (vm.all || checked > 0) {} else if (checked === 0) {
    alert("Select at least one coupon");
  }
}

How can i get the value of the checked checkbox? I'm using only Javascript and AngularJs.

You need to set the checked value when you instantiate the control like this:

angular.module('checkboxExample', [])
    .controller('ExampleController', ['$scope', function($scope) {
      $scope.checkboxModel = {
       value1 : true,
       value2 : 'YES'
     };
    }]);

Then you can check it based on the name you gave the value in the example the checkbox will have both value1 and value2 as properties when checked.

The documentation seems pretty straight forward.
