请检查这个JSFiddle。添加暗淡预设时，它会正确添加到$scope.packData，但不会正确填充输入字段。之后，如果您尝试$scope.packData直接从输入字段更新，它将不起作用。它只能从暗淡的预设中进行。我在这里想念什么？

下面是代码。

var myApp = angular.module('myApp', []);

//myApp.directive('myDirective', function() {});
//myApp.factory('myService', function() {});

function MyCtrl($scope) {
  $scope.packData = [{
    length: null,
    width: null,
    height: null
  }];

  $scope.addNewpack = function() {
    $scope.packData.push({
      length: null,
      width: null,
      height: null
    });
  };

  $scope.removepack = function(index) {
    if ($scope.packData.length != 1) {
      $scope.packData.splice(index, 1);
    }
  };

  $scope.dimPresets = [{
    length: 73,
    width: 54,
    height: 45,
    tare: 2
  }, {
    length: 11,
    width: 11,
    height: 11,
    tare: 1
  }, {
    length: 23,
    width: 23,
    height: 23,
    tare: 4
  }, {
    length: 41,
    width: 52,
    height: 63,
    tare: 6
  }];

  $scope.fillLastpack = function(length, width, height, tare) {
    var lastpack = $scope.packData.length - 1;
    $scope.packData[lastpack] = [{
      "length": length,
      "width": width,
      "height": height
    }];
  }
}

以下是更正后的代码。在您的函数fillLastpack()中，您将一个对象数组推送到packData数组中，而您只需推送一个对象。

更新小提琴

var myApp = angular.module('myApp', []);

//myApp.directive('myDirective', function() {});
//myApp.factory('myService', function() {});

function MyCtrl($scope) {
  $scope.packData = [{
    length: null,
    width: null,
    height: null
  }];

  $scope.addNewpack = function() {
    $scope.packData.push({
      length: null,
      width: null,
      height: null
    });
  };

  $scope.removepack = function(index) {
    if ($scope.packData.length != 1) {
      $scope.packData.splice(index, 1);
    }
  };

  $scope.dimPresets = [{
    length: 73,
    width: 54,
    height: 45,
    tare: 2
  }, {
    length: 11,
    width: 11,
    height: 11,
    tare: 1
  }, {
    length: 23,
    width: 23,
    height: 23,
    tare: 4
  }, {
    length: 41,
    width: 52,
    height: 63,
    tare: 6
  }];

  $scope.fillLastpack = function(length, width, height, tare) {
    var lastpack = $scope.packData.length - 1;
    $scope.packData[lastpack] = {
      "length": length,
      "width": width,
      "height": height
    };
  }
}
