Question

我想在颜色改变时传递一些附加参数吗？

我正在使用这个angularjs颜色选择器。

https://github.com/ruhley/angular-color-picker/

我想像下面那样使用它

var arr =
  [ [ 1 ], [ 2, 3, [ 4, 5, [ 6 ] ] ], [ 7, [ 8, 9 ] ] ]

var flatArr =
  []
  
for (var i = 0; i < arr.length; i = i + 1)
  flatArr = flatArr.concat(arr[i])

console.log(JSON.stringify(arr))
console.log(JSON.stringify(flatArr))
// [[1],[2,3,[4,5,[6]]],[7,[8,9]]]
// [1,2,3,[4,5,[6]],7,[8,9]]

您能帮我解决这个问题吗？

您可以向组件添加属性（例如，id）并在onChange回调中读取（使用api）。

angular.module('app', ['color.picker']).
controller('ctrl', function($scope) {
  $scope.color = '#FF0000';
  $scope.eventApi = {
    onChange:  function(api, color, $event) {
      const id = api.getElement().attr('id');
      console.log(id, color);
    },
  }
});

</div>

颜色更改后如何传递额外的参数？
