Angular 新手。尝试创建一个可重用的指令,以便我可以跨页面共享导航标题栏。每个单独的 html 页面应该能够指定当前或活动页面是什么,因此应用 css 属性来区分该页面。
所有逻辑都应包含在指令中,以便使用此导航栏的每个 html 页面只需要设置 ActivePage 的“属性”。
但是,我似乎无法在模板中获得条件 ng-class 来应用 CSS 类。有人可以帮我发现我的问题吗?
Plunker 示例:http: //plnkr.co/edit/JTI8wLOhN5xWeDdD9i2l
正在使用:
<section ng-app="NavBarApp" ng-controller="NavBarCtrl">
<nav-Bar ActivePage="{{Pages.Navigation.Page2}}"></nav-Bar>
</section>
Javascript:
var Pages = {};
Pages.Navigation = {};
Pages.Navigation.Page1 = {
Name: "Page 1",
BaseLink: "Page1.html"
};
Pages.Navigation.Page2 = {
Name: "Page 2",
BaseLink: "Page2.html"
};
Pages.Navigation.Page3 = {
Name: "Page 3",
BaseLink: "Page3.html"
};
var NavBarApp = angular.module('NavBarApp', []);
NavBarApp.controller('NavBarCtrl', function NavBarCtrl($scope){
$scope.Pages = {};
$scope.Pages.Navigation = Pages.Navigation;
});
NavBarApp.directive('navBar', function(){
return {
restrict: 'E',
replace: true,
scope: {
strActivePage: "@ActivePage"
},
controller: function($scope){
$scope.aryPagesList = [];
for(var strProp in Pages.Navigation){
$scope.aryPagesList.push(Pages.Navigation[strProp]);
}
},
templateUrl: 'NavBarTemplate.html'
};
});
模板:
<div id="NavBar" class="navigation">
<ul>
<li ng-repeat="oCurPage in aryPagesList">
<a id="{{oCurPage.Name}}" ng-class="{active: oCurPage.Name==strActivePage}" href="{{oCurPage.BaseLink}}">{{oCurPage.Name}}</a>
</li>
</ul>
</div>
提前致谢!
