這是我第一個使用angularjs的項目。我正在使用md-data-table作爲角度材料的web應用程序。我安裝了md-data-table，並開始詢問lodash。所以我安裝了lodash。那是當我得到這個[錯誤] [1]。所以我想也許角度洛達什可能會有所幫助，並且我得到另一個錯誤，說_.methods不是函數。我發現一些關於lodash的帖子不再支持某些功能。但我似乎無法找到對我的情況有用的東西。我在這裏錯過了什麼？md-data-table給出錯誤「Can not read property'length'of undefined」
代碼：
var app = angular.module('app', [
'ngMaterial',
'ngMaterialSidemenu',
'mdPickers',
'ui.grid',
'mdDataTable']);
app.controller('appCtrl', function ($scope, $mdDialog, $mdpTimePicker) {
$scope.items = [1, 2, 3, 4, 5];
$scope.selectedItem = $scope.items[0];
$scope.getSelectedText = function() {
if ($scope.selectedItem != undefined) {
return 'You chose ' + $scope.selectedItem + '.';
} else {
return 'Choose an item.';
}
};
$scope.selectedTime = $scope.selectedDate = new Date();
$scope.message = 'Hello';
// directive
$scope.point = {
pointId: '1001'
};
$scope.browser = function (ev) {
var searchByColumns = [
'Point ID',
'Description'
];
var pointList = [{
pointId: '1001',
description: 'point 1'
}, {
pointId: '1002',
description: 'point 2'
}, {
