Now I have Angular JS example with rouring:
How I can specify URL params in Plunker that to check that? I mean to so something like: /test/4 Working example:

Two changes are required:
In app.js, you need to configure $locationProvider for html5Mode:
app.config(['$locationProvider',
function($locationProvider) {
$locationProvider
.html5Mode(true)
.hashPrefix('!');
}
])
In index.html, you need to make your links relative, using html5Mode like: Go to test.
Angular will rewrite the href if the browser doesn't support pushState.

I'm trying to use AngularJS $location to set the browser's url, like this:
$location.path("/post").search({
id: post.id
});
but whenever I do the url gets set like http://localhost:5000/#!/post?id=0 instead of http://localhost:5000/post?id=0
Is there any reason the #!/ shows up?
In app config you should use
$locationProvider.html5Mode(true)
If you want to remove this prefix, add this code to your config:
appModule.config(['$locationProvider', function($locationProvider) {
$locationProvider.hashPrefix('');
}]);
If I call $state.go('login') using Angular ui router, the suburl looks like this.
Is there a way to hide #!/login? It's first time to use angular ui router and I dont know even it's possible.
So I want to see only localhost:3000/
You can create a state without an url in ui-router, by simply not defining the url property when configuring your states.
Like this:
angular.module('app').config(function ($stateProvider) {
$stateProvider.state('login', {
component: 'loginComponent'
});
});
You wont be able to navigate directly to the login url. But you'll still be able to use ui-sref or $state.go('login') to navigate.
If you still want to be able to navigate directly to the login page, you can configure another login state in addition to the above, where you specify the url property.
angular.module('app').config(function ($stateProvider) {
$stateProvider.state('login', {
component: 'loginComponent'
}).state('loginDirect', {
url: '/login',
component: 'loginComponent'
});
});
Try this in your config file:
$locationProvider.hashPrefix('');
For e.g.
angular.module('myPageApp', ['ui.router'])
.config(function ($stateProvider, $locationProvider) {
$stateProvider
.state('app',{
url: '/app',
templateUrl: 'someView.html',
controller: 'appController'
})
...
$locationProvider.hashPrefix('');
});
In above code, you can omit # and ! signs but can't skip the routed state in the URL. You can get the URL as localhost:3000/login or you can set the route on '/' identifier.
If your application does not use HTML5 mode or is being run on browsers that do not support HTML5 mode, and you have not specified your own hash-prefix then client side URLs will now contain a ! prefix.
To make your HTML5 mode ON, try following code.
app.config(['$locationProvider', function($locationProvider) {
$locationProvider.hashPrefix(''); // by default '!'
$locationProvider.html5Mode(true);
}]);
Also in your header section of HTML, add this Base ref type as below:
<head>
...
<base href="/">
</head>
For more information, kindly refer this code application here: https://github.com/TheAjinkya/Angular-UI-Router
Hope its helpful!
i am using angular with web api problem is when i use
$location.url("/home");
home page did not display when i checked user url (in chrome development toll)
http://errors.angularjs.org/1.6.3/$compile/tpload?p0=template%2Fhome.html&p1=undefined&p2=undefined
in url template%2Fhome.html where as my path template/home so what is %2F
kindly help me
regards,
Akmal.
If you are using version 1.4 it won't be a problem. But if you're using 1.5 and up you must supply this in your config:
app.config(['$locationProvider', function($locationProvider) {
$locationProvider.hashPrefix('');
}]);
Try this if the other options don't work:
$timeout(function () {
$location.path('/home');
});
Don't forget to inject $timeout
Do you have the $routeParams service injected in your js file along with $location?
I'd like to read the values of URL query parameters using AngularJS. I'm accessing the HTML with the following URL:
http://127.0.0.1:8080/test.html?target=bob
As expected, location.search is "?target=bob".
For accessing the value of target, I've found various examples listed on the web, but none of them work in AngularJS 1.0.0rc10. In particular, the following are all undefined:
$location.search.target
$location.search['target']
$location.search()['target']
Anyone know what will work? (I'm using $location as a parameter to my controller)
Update:
I've posted a solution below, but I'm not entirely satisfied with it.
The documentation at Developer Guide: Angular Services: Using $location states the following about $location:
When should I use $location?
Any time your application needs to react to a change in the current
URL or if you want to change the current URL in the browser.
For my scenario, my page will be opened from an external webpage with a query parameter, so I'm not "reacting to a change in the current URL" per se. So maybe $location isn't the right tool for the job (for the ugly details, see my answer below). I've therefore changed the title of this question from "How to read query parameters in AngularJS using $location?" to "What's the most concise way to read query parameters in AngularJS?". Obviously I could just use javascript and regular expression to parse location.search, but going that low-level for something so basic really offends my programmer sensibilities.
So: is there a better way to use $location than I do in my answer, or is there a concise alternate?
You can inject $routeParams (requires ngRoute) into your controller. Here's an example from the docs:
// Given:
// URL: http://server.com/index.html#/Chapter/1/Section/2?search=moby
// Route: /Chapter/:chapterId/Section/:sectionId
//
// Then
$routeParams ==> {chapterId:1, sectionId:2, search:'moby'}
EDIT: You can also get and set query parameters with the $location service (available in ng), particularly its search method: $location.search().
$routeParams are less useful after the controller's initial load; $location.search() can be called anytime.
Good that you've managed to get it working with the html5 mode but it is also possible to make it work in the hashbang mode.
You could simply use:
$location.search().target
to get access to the 'target' search param.
For the reference, here is the working jsFiddle: http://web.archive.org/web/20130317065234/http://jsfiddle.net/PHnLb/7/
var myApp = angular.module('myApp', []);
function MyCtrl($scope, $location) {
$scope.location = $location;
$scope.$watch('location.search()', function() {
$scope.target = ($location.search()).target;
}, true);
$scope.changeTarget = function(name) {
$location.search('target', name);
}
}
<div ng-controller="MyCtrl">
Bob
Paul
<hr/>
URL 'target' param getter: {{target}}<br>
Full url: {{location.absUrl()}}
<hr/>
<button ng-click="changeTarget('Pawel')">target=Pawel</button>
</div>
To give a partial answer my own question, here is a working sample for HTML5 browsers:
<!DOCTYPE html>
<html ng-app="myApp">
<head>
<script src="http://code.angularjs.org/1.0.0rc10/angular-1.0.0rc10.js"></script>
<script>
angular.module('myApp', [], function($locationProvider) {
$locationProvider.html5Mode(true);
});
function QueryCntl($scope, $location) {
$scope.target = $location.search()['target'];
}
</script>
</head>
<body ng-controller="QueryCntl">
Target: {{target}}<br/>
</body>
</html>
The key was to call $locationProvider.html5Mode(true); as done above. It now works when opening http://127.0.0.1:8080/test.html?target=bob. I'm not happy about the fact that it won't work in older browsers, but I might use this approach anyway.
An alternative that would work with older browsers would be to drop the html5mode(true) call and use the following address with hash+slash instead:
http://127.0.0.1:8080/test.html#/?target=bob
The relevant documentation is at Developer Guide: Angular Services: Using $location (strange that my google search didn't find this...).
It can be done by two ways:
Using $routeParams
Best and recommended solution is to use $routeParams into your controller.
It Requires the ngRoute module to be installed.
function MyController($scope, $routeParams) {
// URL: http://server.com/index.html#/Chapter/1/Section/2?search=moby
// Route: /Chapter/:chapterId/Section/:sectionId
// $routeParams ==> {chapterId:'1', sectionId:'2', search:'moby'}
var search = $routeParams.search;
}
Using $location.search().
There is a caveat here. It will work only with HTML5 mode. By default, it does not work for the URL which does not have hash(#) in it http://localhost/test?param1=abc¶m2=def
You can make it work by adding #/ in the URL. http://localhost/test#/?param1=abc¶m2=def
$location.search() to return an object like:
{
param1: 'abc',
param2: 'def'
}
$location.search() will work only with HTML5 mode turned on and only on supporting browser.
This will work always:
$window.location.search
Just to summerize .
If your app is being loaded from external links then angular wont detect this as a URL change so $loaction.search() would give you an empty object . To solve this you need to set following in your app config(app.js)
.config(['$routeProvider', '$locationProvider', function ($routeProvider, $locationProvider)
{
$routeProvider
.when('/', {
templateUrl: 'views/main.html',
controller: 'MainCtrl'
})
.otherwise({
redirectTo: '/'
});
$locationProvider.html5Mode(true);
}]);
Just a precision to Ellis Whitehead's answer. $locationProvider.html5Mode(true); won't work with new version of angularjs without specifying the base URL for the application with a <base href=""> tag or setting the parameter requireBase to false
From the doc :
If you configure $location to use html5Mode (history.pushState), you need to specify the base URL for the application with a tag or configure $locationProvider to not require a base tag by passing a definition object with requireBase:false to $locationProvider.html5Mode():
$locationProvider.html5Mode({
enabled: true,
requireBase: false
});
you could also use $location.$$search.yourparameter
I found that for an SPA HTML5Mode causes lots of 404 error problems, and it is not necessary to make $location.search work in this case. In my case I want to capture a URL query string parameter when a user comes to my site, regardless of which "page" they initially link to, AND be able to send them to that page once they log in. So I just capture all that stuff in app.run
$rootScope.$on('$stateChangeStart', function (e, toState, toParams, fromState, fromParams) {
if (fromState.name === "") {
e.preventDefault();
$rootScope.initialPage = toState.name;
$rootScope.initialParams = toParams;
return;
}
if ($location.search().hasOwnProperty('role')) {
$rootScope.roleParameter = $location.search()['role'];
}
...
}
then later after login I can say
$state.go($rootScope.initialPage, $rootScope.initialParams)
It's a bit late, but I think your problem was your URL. If instead of
