我已经制作了一个自定义指令并使用了ng-model,但是当模型更新时,该指令即使我正在观看该事件.这是代码:

angular.module('Directives').directive("customDirective", ['$window', function ($window) {

return {
    restrict: "E",
    require: 'ngModel',
    scope: {
        ngModel: '=',
    },
    link: function (scope, elem, attrs, ngModel) {

        // IF the model changes, re-render
        scope.$watch('ngModel', function (newVal, oldVal) {
            render();
        });

        // We want to re-render in case of resize
        angular.element($window).bind('resize', function () {
            //this does work
            render();
        })

        var render = function () {
            //doing some work here
        };
    }
}}]);

和观点:

<div ng-repeat="product in pageCtrl.productList track by product.id">
<h3>{{ product.name }}</h3>
<custom-directive …

我无法在Windows 7上安装grunt

我正在尝试通过此命令安装它:

npm install ?g grunt?cli
