为了好玩,我创建了一个创建标签式导航的指令。 这是指令:
define(['angular'], function (ng) {
var directives = ng.module('directives', []);
/* top navigation tabs */
directives.directive('tabset', function () {
return {
restrict: 'E',
scope: {},
transclude: true,
replace: true,
templateUrl: 'common/components/directives/templates/tabset.tpl.html'
};
})
.directive('tab', ['$location', function ($location) {
return {
restrict: 'E',
replace: true,
scope: {
route: '@',
title: '@'
},
link: function (scope, element, attrs) {
var route = attrs.route;
scope.location = $location;
scope.active = false;
scope.$watch('location.path()', function (new_route) {
scope.active = route === new_route;
});
},
templateUrl: 'common/components/directives/templates/tab.tpl.html'
};
}]);
return directives;
});
Angular不断抛出此错误:
TypeError: undefined is not a function

我不知道为什么。我没有看到任何我尝试用作函数的undefined
。
有人可以帮忙吗?
错误是不规则的,但大部分时间都是抛出的。 也许它与异步加载有关? 它似乎只发生在页面加载上,而不是在浏览网站时。
我在后台使用grunt。 我也使用requirejs。
除此之外,它似乎应该像它应该的那样工作。
tab.tpl.html:
<li data-ng-class="{active: active}">
<a href="#{{route}}">{{title}}</a>
</li>
tabset.tpl.html:
<ul class="nav nav-tabs" ng-transclude></ul>
用法:
<tabset>
<tab data-route="/home" data-title="Home"></tab>
<tab data-route="/tournaments" data-title="Tournaments"></tab>
<tab data-route="/about" data-title="About"></tab>
</tabset>
