AngularJS是否有助于在当前页面的链接上设置active
类?
我想有一些神奇的方法可以完成,但我似乎无法找到。
我的菜单如下:
<ul>
<li><a class="active" href="/tasks">Tasks</a>
<li><a href="/actions">Tasks</a>
</ul>
我在我的路线中为每个人设置了控制器:TasksController
和ActionsController
。
但我无法想出一种方法将a
链接上的“活动”类绑定到控制器。
任何提示?

在视图
上<a ng-class="getClass('/tasks')" href="/tasks">Tasks</a>
控制器上的
$scope.getClass = function (path) {
return ($location.path().substr(0, path.length) === path) ? 'active' : '';
}
这样,任务链接将在任何以'/tasks'(例如'/ tasks / 1 / reports')开头的网址中包含活动类

我建议在链接上使用指令。
但它还不完美。注意hashbangs;)
以下是javascript for directive:
angular.module('link', []).
directive('activeLink', ['$location', function (location) {
return {
restrict: 'A',
link: function(scope, element, attrs, controller) {
var clazz = attrs.activeLink;
var path = attrs.href;
path = path.substring(1); //hack because path does not return including hashbang
scope.location = location;
scope.$watch('location.path()', function (newPath) {
if (path === newPath) {
element.addClass(clazz);
} else {
element.removeClass(clazz);
}
});
}
};
}]);
以下是如何在html中使用它:
<div ng-app="link">
<a href="#/one" active-link="active">One</a>
<a href="#/two" active-link="active">One</a>
<a href="#" active-link="active">home</a>
</div>
然后使用css设置样式:
.active { color: red; }

这是一个适用于Angular的简单方法。
<ul>
<li ng-class="{ active: isActive('/View1') }"><a href="#/View1">View 1</a></li>
<li ng-class="{ active: isActive('/View2') }"><a href="#/View2">View 2</a></li>
<li ng-class="{ active: isActive('/View3') }"><a href="#/View3">View 3</a></li>
</ul>
在AngularJS控制器中:
$scope.isActive = function (viewLocation) {
var active = (viewLocation === $location.path());
return active;
};
此主题还有许多其他类似的答案。

为了在辩论中添加我的两分钱,我已经制作了一个纯角度模块(没有jQuery),它也可以使用包含数据的哈希网址。 (例如#/this/is/path?this=is&some=data
)
您只需将模块添加为依赖项,并将auto-active
添加到菜单的其中一个祖先。像这样:
<ul auto-active>
<li><a href="#/">main</a></li>
<li><a href="#/first">first</a></li>
<li><a href="#/second">second</a></li>
<li><a href="#/third">third</a></li>
</ul>
模块看起来像这样:
(function () {
angular.module('autoActive', [])
.directive('autoActive', ['$location', function ($location) {
return {
restrict: 'A',
scope: false,
link: function (scope, element) {
function setActive() {
var path = $location.path();
if (path) {
angular.forEach(element.find('li'), function (li) {
var anchor = li.querySelector('a');
if (anchor.href.match('#' + path + '(?=\\?|$)')) {
angular.element(li).addClass('active');
} else {
angular.element(li).removeClass('active');
}
});
}
}
setActive();
scope.$on('$locationChangeSuccess', setActive);
}
}
}]);
}());
(你当然可以使用指令部分)
值得注意的是,这不适用于空哈希(例如example.com/#
或仅example.com
),它至少需要example.com/#/
或example.com#/
。但这会在ngResource等情况下自动发生。

在我的情况下,我通过创建一个负责导航的简单控制器来解决这个问题
angular.module('DemoApp')
.controller('NavigationCtrl', ['$scope', '$location', function ($scope, $location) {
$scope.isCurrentPath = function (path) {
return $location.path() == path;
};
}]);
只需将ng-class添加到元素中即可:
<ul class="nav" ng-controller="NavigationCtrl">
<li ng-class="{ active: isCurrentPath('/') }"><a href="#/">Home</a></li>
<li ng-class="{ active: isCurrentPath('/about') }"><a href="#/about">About</a></li>

以下是我在阅读了上述一些优秀建议后提出的解决方案。在我的特殊情况下,我试图使用Bootstrap tabs component作为我的菜单,但不想使用Angular-UI版本,因为我希望标签充当菜单,其中每个标签都是书签 - 能够,而不是作为单个页面的导航的选项卡。 (如果您对Angular-UI版本的引导选项卡的外观感兴趣,请参阅http://angular-ui.github.io/bootstrap/#/tabs。
我真的很喜欢kfis关于创建自己的指令来处理这个问题的答案,但是有一个指令需要放在每个链接上似乎很麻烦。所以我创建了自己的Angular指令,该指令在ul
上放置一次。为了防止其他任何人试图做同样的事情,我想我会在这里发布,但正如我所说,许多上述解决方案也可以。对于javascript而言,这是一个稍微复杂的解决方案,但它创建了一个具有最小标记的可重用组件。
以下是指令的javascript和ng:view
的路由提供程序:
var app = angular.module('plunker', ['ui.bootstrap']).
config(['$routeProvider', function($routeProvider) {
$routeProvider.
when('/One', {templateUrl: 'one.html'}).
when('/Two', {templateUrl: 'two.html'}).
when('/Three', {templateUrl: 'three.html'}).
otherwise({redirectTo: '/One'});
}]).
directive('navTabs', ['$location', function(location) {
return {
restrict: 'A',
link: function(scope, element) {
var $ul = $(element);
$ul.addClass("nav nav-tabs");
var $tabs = $ul.children();
var tabMap = {};
$tabs.each(function() {
var $li = $(this);
//Substring 1 to remove the # at the beginning (because location.path() below does not return the #)
tabMap[$li.find('a').attr('href').substring(1)] = $li;
});
scope.location = location;
scope.$watch('location.path()', function(newPath) {
$tabs.removeClass("active");
tabMap[newPath].addClass("active");
});
}
};
}]);
然后在您的HTML中,您只需:
<ul nav-tabs>
<li><a href="#/One">One</a></li>
<li><a href="#/Two">Two</a></li>
<li><a href="#/Three">Three</a></li>
</ul>

你可以非常简单地实现这个,这是一个例子:

<ul class="menu">
<li ng-class="menuClass('home')"><a href="#home">Page1</a></li>
<li ng-class="menuClass('about')"><a href="#about">Page2</a></li>
</ul>
</div>
你的控制器应该是这样的:
app.controller("MenuCtrl", function($scope, $location) {
$scope.menuClass = function(page) {
var current = $location.path().substring(1);
return page === current ? "active" : "";
};
});

我在菜单位于控制器范围内时遇到了类似的问题。不确定这是最好的解决方案还是推荐的解决方案,但这对我有用。我已将以下内容添加到我的应用配置中:
var app = angular.module('myApp');

$rootScope.menuActive = function(url, exactMatch){
if (exactMatch){
return $location.path() == url;
}
else {
return $location.path().indexOf(url) == 0;
}
}
});
然后在视图中我有:
<li><a href="/" ng-class="{true: 'active'}[menuActive('/', true)]">Home</a></li>
<li><a href="/register" ng-class="{true: 'active'}[menuActive('/register')]">

使用指令(因为我们在这里进行DOM操作)以下可能是最接近“角度方式”的事情:
$scope.timeFilters = [
{'value':3600,'label':'1 hour'},
{'value':10800,'label':'3 hours'},
{'value':21600,'label':'6 hours'},
{'value':43200,'label':'12 hours'},
{'value':86400,'label':'24 hours'},
{'value':604800,'label':'1 week'}
]
angular.module('whatever', []).directive('filter',function(){
return{
restrict: 'A',
template: '<li ng-repeat="time in timeFilters" class="filterItem"><a ng-click="changeTimeFilter(time)">{{time.label}}</a></li>',
link: function linkFn(scope, lElement, attrs){
var menuContext = attrs.filter;
scope.changeTimeFilter = function(newTime){
scope.selectedtimefilter = newTime;
}
lElement.bind('click', function(cevent){
var currentSelection = angular.element(cevent.srcElement).parent();
var previousSelection = scope[menuContext];
if(previousSelection !== currentSelection){
if(previousSelection){
angular.element(previousSelection).removeClass('active')
}
scope[menuContext] = currentSelection;
scope.$apply(function(){
currentSelection.addClass('active');
})
}
})
}
}
})
然后你的HTML看起来像:
<ul class="dropdown-menu" filter="times"></ul>

我是这样做的:
var myApp = angular.module('myApp', ['ngRoute']);
myApp.directive('trackActive', function($location) {
function link(scope, element, attrs){
scope.$watch(function() {
return $location.path();
}, function(){
var links = element.find('a');
links.removeClass('active');
angular.forEach(links, function(value){
var a = angular.element(value);
if (a.attr('href') == '#' + $location.path() ){
a.addClass('active');
}
});
});
}
return {link: link};
});
这使您可以在具有track-active指令的部分中包含链接:
<nav track-active>
<a href="#/">Page 1</a>
<a href="#/page2">Page 2</a>
<a href="#/page3">Page 3</a>
</nav>
对我来说,这种方法似乎比其他方法更清晰。
另外,如果你正在使用jQuery,你可以使它更整洁,因为jQlite只有基本的选择器支持。在包含角度之前包含jquery的更干净的版本将如下所示:
myApp.directive('trackActive', function($location) {
function link(scope, element, attrs){
scope.$watch(function() {
return $location.path();
}, function(){
element.find('a').removeClass('active').find('[href="#'+$location.path()+'"]').addClass('active');
});
}
return {link: link};
});

我对此问题的解决方案,请在角度模板中使用route.current
。
如果要在菜单中突出显示/tasks
路线,可以将自己的属性menuItem
添加到模块声明的路线中:
$routeProvider.
when('/tasks', {
menuItem: 'TASKS',
templateUrl: 'my-templates/tasks.html',
controller: 'TasksController'
);
然后在您的模板tasks.html
中,您可以使用以下ng-class
指令:
<a href="app.html#/tasks"
ng-class="{active : route.current.menuItem === 'TASKS'}">Tasks</a>
在我看来,这比所有提议的解决方案都要清晰得多。

这是kfis指令的扩展,我做了允许不同级别的路径匹配。基本上我发现需要匹配一定深度的URL路径,因为精确匹配不允许嵌套和默认状态重定向。希望这会有所帮助。
.directive('selectedLink', ['$location', function(location) {
return {
restrict: 'A',
scope:{
selectedLink : '='
},
link: function(scope, element, attrs, controller) {
var level = scope.selectedLink;
var path = attrs.href;
path = path.substring(1); //hack because path does not return including hashbang
scope.location = location;
scope.$watch('location.path()', function(newPath) {
var i=0;
p = path.split('/');
n = newPath.split('/');
for( i ; i < p.length; i++) {
if( p[i] == 'undefined' || n[i] == 'undefined' || (p[i] != n[i]) ) break;
}
if ( (i-1) >= level) {
element.addClass("selected");
}
else {
element.removeClass("selected");
}
});
}
};
}]);
以下是我如何使用链接
<nav>
<a href="#/info/project/list" selected-link="2">Project</a>
<a href="#/info/company/list" selected-link="2">Company</a>
<a href="#/info/person/list" selected-link="2">Person</a>

<li class="nav-item" routerLink="/contact" routerLinkActive="active">
<a class="nav-link" href="/contact">Contact</a>

上述指令建议都不适合我。如果您有像这样的引导导航栏
<ul class="nav navbar-nav">
<li><a ng-href="#/">Home</a></li>
<li><a ng-href="#/about">About</a></li>
...
</ul>
(可能是$ yo angular
启动)然后您要将.active
添加到父 <li>
元素类列表中,而不是元素本身;即<li class="active">..</li>
。所以我写了这个:
.directive('setParentActive', ['$location', function($location) {
return {
restrict: 'A',
link: function(scope, element, attrs, controller) {
var classActive = attrs.setParentActive || 'active',
path = attrs.ngHref.replace('#', '');
scope.location = $location;
scope.$watch('location.path()', function(newPath) {
if (path == newPath) {
element.parent().addClass(classActive);
} else {
element.parent().removeClass(classActive);
}
})
}
}
}])
用法set-parent-active
; .active
是默认值,因此无需设置
<li><a ng-href="#/about" set-parent-active>About</a></li>
当链接处于活动状态时,并且父<li>
元素将为.active
。要使用其他.active
类.highlight
,只需
<li><a ng-href="#/about" set-parent-active="highlight">About</a></li>

根据@kfis的回答,它是评论,我的建议,最终指令如下:
.directive('activeLink', ['$location', function (location) {
return {
restrict: 'A',
link: function(scope, element, attrs, controller) {
var clazz = attrs.activeLink;
var path = attrs.href||attrs.ngHref;
path = path.substring(1); //hack because path does not return including hashbang
scope.location = location;
scope.$watch('window.location.href', function () {
var newPath = (window.location.pathname + window.location.search).substr(1);
if (path === newPath) {
element.addClass(clazz);
} else {
element.removeClass(clazz);
}
});
}
};
}]);
以下是如何在html中使用它:
<div ng-app="link"> <a href="#/one" active-link="active">One</a> <a href="#/two" active-link="active">One</a> <a href="#" active-link="active">home</a> </div>

如果你想在包装器中使用指令的链接而不是选择每个单独的链接(这样可以更容易地查看Batarang中的范围),这也很有效:
angular.module("app").directive("navigation", [
"$location", function($location) {
return {
restrict: 'A',
scope: {},
link: function(scope, element) {
var classSelected, navLinks;
scope.location = $location;
classSelected = 'selected';
navLinks = element.find('a');
scope.$watch('location.path()', function(newPath) {
var el;
el = navLinks.filter('[href="' + newPath + '"]');
navLinks.not(el).closest('li').removeClass(classSelected);
return el.closest('li').addClass(classSelected);
});
}
};
}
]);
Markup就是:
<nav role="navigation" data-navigation>
<ul>
<li><a href="/messages">Messages</a></li>
<li><a href="/help">Help</a></li>
<li><a href="/details">Details</a></li>

这是另一个突出显示活动链接的指令。
.directive('activeLink', ['$location',
function($location) {
return {
restrict: 'A',
link: function(scope, elem, attrs) {
var path = attrs.activeLink ? 'activeLink' : 'href';
var target = angular.isDefined(attrs.activeLinkParent) ? elem.parent() : elem;
var disabled = angular.isDefined(attrs.activeLinkDisabled) ? true : false;
var nested = angular.isDefined(attrs.activeLinkNested) ? true : false;
function inPath(needle, haystack) {
var current = (haystack == needle);
if (nested) {
current |= (haystack.indexOf(needle + '/') == 0);
}
return current;
}
function toggleClass(linkPath, locationPath) {
// remove hash prefix and trailing slashes
linkPath = linkPath ? linkPath.replace(/^#!/, '').replace(/\/+$/, '') : '';
locationPath = locationPath.replace(/\/+$/, '');
if (linkPath && inPath(linkPath, locationPath)) {
target.addClass('active');
if (disabled) {
target.removeClass('disabled');
}
} else {
target.removeClass('active');
if (disabled) {
target.addClass('disabled');
}
}
}
// watch if attribute value changes / evaluated
attrs.$observe(path, function(linkPath) {
toggleClass(linkPath, $location.path());
});
// watch if location changes
scope.$watch(
function() {
return $location.path();
},
function(newPath) {
toggleClass(attrs[path], newPath);
}
);
}
};
}
]);
使用角度表达式的简单示例,假设 $ scope.var = 2 ,如果位置为 / url / 2 ,则链接将处于活动状态:
<a href="#!/url/{{var}}" active-link>
Bootstrap示例,parent li将获得活动类:
<li>
<a href="#!/url" active-link active-link-parent>
</li>
嵌套网址示例,如果任何嵌套网址处于活动状态,则链接将处于活动状态(即 / url / 1 , / url / 2 , url / 1 / 2 /...)
<a href="#!/url" active-link active-link-nested>
复杂示例,链接指向一个网址( / url1 ),但如果选择了另一个网址,则会处于活动状态( / url2 ):
<a href="#!/url1" active-link="#!/url2" active-link-nested>
已停用链接的示例,如果未激活,则会&#39;禁用&#39; 类:
<a href="#!/url" active-link active-link-disabled>
所有 active-link - * 属性都可以任意组合使用,因此可以实现非常复杂的条件。

// Get current location
var currentPath = $location.path();
// Get location the link is pointing to

.directive('whenActive',
[
'$location',
($location)->
scope: true,
link: (scope, element, attr)->
scope.$on '$routeChangeSuccess',
() ->
loc = "#"+$location.path()
href = element.attr('href')
state = href.indexOf(loc)
substate = -1
if href.length > 3
substate = loc.indexOf(href)
if loc.length is 2
state = -1
#console.log "Is Loc: "+loc+" in Href: "+href+" = "+state+" and Substate = "+substate
if state isnt -1 or substate isnt -1
element.addClass 'selected'
element.parent().addClass 'current-menu-item'
else if href is '#' and loc is '#/'
element.addClass 'selected'
element.parent().addClass 'current-menu-item'
else
element.removeClass 'selected'
element.parent().removeClass 'current-menu-item'
])

$scope.getClass = function (path) {
return String(($location.absUrl().split('?')[0]).indexOf(path)) > -1 ? 'active' : ''
}
<li class="listing-head" ng-class="getClass('/v/bookings')"><a href="/v/bookings">MY BOOKING</a></li>
<li class="listing-head" ng-class="getClass('/v/fleets')"><a href="/v/fleets">MY FLEET</a></li>
<li class="listing-head" ng-class="getClass('/v/adddriver')"><a href="/v/adddriver">ADD DRIVER</a></li>
<li class="listing-head" ng-class="getClass('/v/bookings')"><a href="/v/invoice">INVOICE</a></li>
<li class="listing-head" ng-class="getClass('/v/profile')"><a href="/v/profile">MY PROFILE</a></li>
<li class="listing-head"><a href="/v/logout">LOG OUT</a></li>

我找到了最简单的解决方案。只是为了比较HTML中的indexOf
var myApp = angular.module('myApp',[]);
myApp.run(function($rootScope) {
$rootScope.$on("$locationChangeStart", function(event, next, current) {
$rootScope.isCurrentPath = $location.path();
});
});
<li class="{{isCurrentPath.indexOf('help')>-1 ? 'active' : '' }}">
<a href="/#/help/">
Help
</a>
</li>

对我来说最重要的是不要改变所有的bootstrap默认代码。 这是我的菜单控制器,它搜索菜单选项,然后添加我们想要的行为。
file: header.js
function HeaderCtrl ($scope, $http, $location) {
$scope.menuLinkList = [];
defineFunctions($scope);
addOnClickEventsToMenuOptions($scope, $location);
}
function defineFunctions ($scope) {
$scope.menuOptionOnClickFunction = function () {
for ( var index in $scope.menuLinkList) {
var link = $scope.menuLinkList[index];
if (this.hash === link.hash) {
link.parentElement.className = 'active';
} else {
link.parentElement.className = '';
}
}
};
}
function addOnClickEventsToMenuOptions ($scope, $location) {
var liList = angular.element.find('li');
for ( var index in liList) {
var liElement = liList[index];
var link = liElement.firstChild;
link.onclick = $scope.menuOptionOnClickFunction;
$scope.menuLinkList.push(link);
var path = link.hash.replace("#", "");
if ($location.path() === path) {
link.parentElement.className = 'active';
}
}
}
