如何使用角度控制器当前网址参数 [英] How to use current url params in angular controller
问题描述
我在URL中的动态值PARAMS和我想要得到它,当onload事件中使用的控制器
但我不知道如何应对 $ route.current.params
I have a dynamic value params in url and I want to get it and use in controller when onload
But I have no idea how to deal with $route.current.params
让说我有这条路线提供商
Let say I have this route provider
$routeProvider.when('foo/:bar', {templateUrl: 'template.html'};
然后在我的控制器
Then in my controller
app.controller('mapCtrl', function($scope, $route, $routeParams) {
var param = $route.current.params.bar;
console.log(param);
});
如果用户访问富/ ABCDEFG
假设应显示在控制台ABCDEFG,但我得到了错误。
无法读取属性''未定义PARAMS
If user access foo/abcdefg
suppose should show abcdefg in console but I got error.
'Cannot read property 'params' of undefined'
推荐答案
例如:
在你app_route.js你必须URL模式链接到一个特定的控制器和用于显示DATAS模板:
In you app_route.js you have to link url pattern to a specific controller and the template to use for displaying datas:
angular.module('mapApp', []).
config(['$routeProvider', function($routeProvider){
$routeProvider.when('/foo/:bar', {templateUrl: './view/partial/template.html', controller: mapCtrl});
$routeProvider.otherwise({redirectTo: '/foo/01'});
}
]);
在您的特定的控制器添加逻辑(由巴这里选择数据):
同样使用$ routeParams&安培; $ route.current.params
In your specific controller you add the logic (here select data by bar) : Same using for $routeParams & $route.current.params
function mapCtrl($scope, $routeParams, $http) {
$http.get('./data/myDatas.json').success( function(data){
var arr = new Array();
for(var i=0; i < data.length; i++){
if(data[i].bar == $routeParams.bar){
arr.push(data[i]); }
}
$scope.items = arr;
});
}
mapCtrl.$inject = ['$scope', '$routeParams', '$http']; //for minified bug issue
而在你的template.html,布局:
And in your template.html, the layout :
<div ng-repeat="item in items">
<h3>{{item.bar}}</h3>
</div>
不要忘了添加你想要展示你的DATAS索引页的NG-视图,NG-应用=mapApp在html标记。
Don't forget add the ng-view on your index page where you want displaying datas, and ng-app="mapApp" in html tag.
