AngularJS-如何使用 $routeParams 生成 templateUrl?

我们的应用程序具有2级导航。我们希望使用 AngularJS$routeProvider来动态地为 <ng-view />提供模板。我在考虑做一些类似这样的事情:

angular.module('myApp', []).
config(['$routeProvider', function($routeProvider) {
$routeProvider.when('/:primaryNav/:secondaryNav', {
templateUrl: 'resources/angular/templates/nav/'+<<primaryNavHere>>+'/'+<<secondaryNavHere>>+'.html'
});
}]);

我只是不知道如何填充 <<>>中的部分。我知道主导航和辅助导航被绑定到 $routeParams,但是我如何在这里访问 $routeParams 以便动态地提供模板?

I couldn't find a way to inject and use the $routeParams service (which I would assume would be a better solution) I tried this thinking it might work:

angular.module('myApp', []).
config(function ($routeProvider, $routeParams) {
$routeProvider.when('/:primaryNav/:secondaryNav', {
templateUrl: 'resources/angular/templates/nav/'+$routeParams.primaryNav+'/'+$routeParams.secondaryNav+'.html'
});
});

Which yielded this error:

Unknown provider: $routeParams from myApp

If something like that isn't possible you can change your templateUrl to point to a partial HTML file that just has ng-include and then set the URL in your controller using $routeParams like this:

angular.module('myApp', []).
config(function ($routeProvider) {
$routeProvider.when('/:primaryNav/:secondaryNav', {
templateUrl: 'resources/angular/templates/nav/urlRouter.html',
controller: 'RouteController'
});
});


function RouteController($scope, $routeParams) {
$scope.templateUrl = 'resources/angular/templates/nav/'+$routeParams.primaryNav+'/'+$routeParams.secondaryNav+'.html';
}

With this as your urlRouter.html

<div ng-include src="templateUrl"></div>

I've added support for this in my fork of angular. It allows you to specify

$routeProvider
.when('/:some/:param/:filled/:url', {
templateUrl:'/:some/:param/:filled/template.ng.html'
});

not sure this will get picked up as it is kind of against the grain for angular, but it is useful to me

Alright, think I got it...

Little background first: The reason I needed this was to stick Angular on top of Node Express and have Jade process my partials for me.

So here's whatchya gotta do... (drink beer and spend 20+ hours on it first!!!)...

When you set up your module, save the $routeProvider globally:

// app.js:
var routeProvider
, app = angular.module('Isomorph', ['ngResource']).config(function($routeProvider){


routeProvider = $routeProvider;
$routeProvider
.when('/', {templateUrl: '/login', controller: 'AppCtrl'})
.when('/home', {templateUrl: '/', controller: 'AppCtrl'})
.when('/login', {templateUrl: '/login', controller: 'AppCtrl'})
.when('/SAMPLE', {templateUrl: '/SAMPLE', controller: 'SAMPLECtrl'})
.when('/map', {templateUrl: '/map', controller: 'MapCtrl'})
.when('/chat', {templateUrl: '/chat', controller: 'ChatCtrl'})
.when('/blog', {templateUrl: '/blog', controller: 'BlogCtrl'})
.when('/files', {templateUrl: '/files', controller: 'FilesCtrl'})
.when('/tasks', {templateUrl: '/tasks', controller: 'TasksCtrl'})
.when('/tasks/new', {templateUrl: '/tasks/new', controller: 'NewTaskCtrl'})
.when('/tasks/:id', {templateUrl: '/tasks', controller: 'ViewTaskCtrl'})
.when('/tasks/:id/edit', {templateUrl: '/tasks', controller: 'EditTaskCtrl'})
.when('/tasks/:id/delete', {templateUrl: '/tasks', controller: 'DeleteTaskCtrl'})
.otherwise({redirectTo: '/login'});


});


// ctrls.js
...
app.controller('EditTaskCtrl', function($scope, $routeParams, $location, $http){


var idParam = $routeParams.id;
routeProvider.when('/tasks/:id/edit/', {templateUrl: '/tasks/' + idParam + '/edit'});
$location.path('/tasks/' + idParam + '/edit/');


});
...

That may be more info than what was needed...

  • Basically, you'll wanna store your Module's $routeProvider var globally, eg as routeProvider so that it can be accessed by your Controllers.

  • Then you can just use routeProvider and create a NEW route (you can't 'RESET a route' / 'REpromise'; you must create a new one), I just added a slash (/) at the end so that it is as semantic as the first.

  • Then (inside your Controller), set the templateUrl to the view you want to hit.

  • Take out the controller property of the .when() object, lest you get an infinite request loop.

  • And finally (still inside the Controller), use $location.path() to redirect to the route that was just created.

If you're interested in how to slap an Angular app onto an Express app, you can fork my repo here: https://github.com/cScarlson/isomorph.

And this method also allows for you to keep the AngularJS Bidirectional Data-Bindings in case you want to bind your HTML to your database using WebSockets: otherwise without this method, your Angular data-bindings will just output \{\{model.param}}.

If you clone this at this time, you'll need mongoDB on your machine to run it.

Hope this solves this issue!

Don't drink your bathwater.

This very helpful feature is now available starting at version 1.1.2 of AngularJS. It's considered unstable but I have used it (1.1.3) and it works fine.

Basically you can use a function to generate a templateUrl string. The function is passed the route parameters that you can use to build and return the templateUrl string.

var app = angular.module('app',[]);


app.config(
function($routeProvider) {
$routeProvider.
when('/', {templateUrl:'/home'}).
when('/users/:user_id',
{
controller:UserView,
templateUrl: function(params){ return '/users/view/' + params.user_id; }
}
).
otherwise({redirectTo:'/'});
}
);

Many thanks to https://github.com/lrlopez for the pull request.

Router:-

...
.when('/enquiry/:page', {
template: '<div ng-include src="templateUrl" onload="onLoad()"></div>',
controller: 'enquiryCtrl'
})
...

Controller:-

...
// template onload event
$scope.onLoad = function() {
console.log('onLoad()');
f_tcalInit();  // or other onload stuff
}


// initialize
$scope.templateUrl = 'ci_index.php/adminctrl/enquiry/'+$routeParams.page;
...

I believe it is a weakness in angularjs that $routeParams is NOT visible inside the router. A tiny enhancement would make a world of difference during implementation.

I was having a similar issue and used $stateParams instead of routeParam

templateUrl can be use as function with returning generated URL. We can manipulate url with passing argument which takes routeParams.

See the example.

.when('/:screenName/list',{
templateUrl: function(params){
return params.screenName +'/listUI'
}
})

Hope this help.

//module dependent on ngRoute
var app=angular.module("myApp",['ngRoute']);
//spa-Route Config file
app.config(function($routeProvider,$locationProvider){
$locationProvider.hashPrefix('');
$routeProvider
.when('/',{template:'HOME'})
.when('/about/:paramOne/:paramTwo',{template:'ABOUT',controller:'aboutCtrl'})
.otherwise({template:'Not Found'});
}
//aboutUs controller
app.controller('aboutCtrl',function($routeParams){
$scope.paramOnePrint=$routeParams.paramOne;
$scope.paramTwoPrint=$routeParams.paramTwo;
});

in index.html

<a ng-href="#/about/firstParam/secondParam">About</a>

firstParam and secondParam can be anything according to your needs.
