假设你正在使用路由:
// bootstrap
myApp.config(['$routeProvider', '$locationProvider', function ($routeProvider, $locationProvider) {
$routeProvider.when('/home', {
templateUrl: 'partials/home.html',
controller: 'HomeCtrl'
});
$routeProvider.when('/about', {
templateUrl: 'partials/about.html',
controller: 'AboutCtrl'
});
...
在html中,当单击按钮时,您希望导航到关于页面。一种方法是
<a href="#/about">
... 但是ng-click似乎在这里也很有用。
这个假设正确吗?用ng-click代替anchor?
如果是的话,它是如何运作的呢?即:
<div ng-click=“/about”>
使用自定义属性(用指令实现)可能是最简洁的方法。这是我的版本,基于@Josh和@sean的建议。
angular.module('mymodule', [])
// Click to navigate
// similar to <a href="#/partial"> but hash is not required,
// e.g. <div click-link="/partial">
.directive('clickLink', ['$location', function($location) {
return {
link: function(scope, element, attrs) {
element.on('click', function() {
scope.$apply(function() {
$location.path(attrs.clickLink);
});
});
}
}
}]);
它有一些有用的特性,但我是Angular的新手,所以可能还有改进的空间。
我使用ng-click指令调用一个函数,同时请求route templateUrl,以决定哪个<div>必须显示或隐藏在route templateUrl页面或不同的场景。
手指1.6.9
让我们看一个例子,当在路由页面,我需要添加<div>或编辑<div>,我控制使用父控制器模型$作用域。addProduct和$scope。editProduct布尔。

两页都是
RoutingTesting.html(父),TestingPage.html(路由页面)在同一目录,
希望这能帮助到一些人。
