How to pass parameters using ui-sref in ui-router to the controller

I've created an example to show how to. Updated state definition would be:

 $stateProvider .state('home', { url: '/:foo?bar', views: { '': { templateUrl: 'tpl.home.html', controller: 'MainRootCtrl' }, ... } 

And this would be the controller:

.controller('MainRootCtrl', function($scope, $state, $stateParams) { //.. var foo = $stateParams.foo; //getting fooVal var bar = $stateParams.bar; //getting barVal //.. $scope.state = $state.current $scope.params = $stateParams; }) 

What we can see is that the state home now has url defined as:

url: '/:foo?bar', 

which means, that the params in url are expected as

/fooVal?bar=barValue 

These two links will correctly pass arguments into the controller:

<a ui-sref="home({foo: 'fooVal1', bar: 'barVal1'})"> <a ui-sref="home({foo: 'fooVal2', bar: 'barVal2'})"> 

Also, the controller does consume $stateParams instead of $stateParam.

Link to doc:

• URL Parameters

You can check it here

params : {}

There is also new, more granular setting params : {}. As we've already seen, we can declare parameters as part of url. But with params : {} configuration - we can extend this definition or even introduce paramters which are not part of the url:

.state('other', { url: '/other/:foo?bar', params: { // here we define default value for foo // we also set squash to false, to force injecting // even the default value into url foo: { value: 'defaultValue', squash: false, }, // this parameter is now array // we can pass more items, and expect them as [] bar : { array : true, }, // this param is not part of url // it could be passed with $state.go or ui-sref hiddenParam: 'YES', }, ... 

Settings available for params are described in the documentation of the $stateProvider

Below is just an extract

• value - {object|function=}: specifies the default value for this parameter. This implicitly sets this parameter as optional...
• array - {boolean=}: (default: false) If true, the param value will be treated as an array of values.
• squash - {bool|string=}: squash configures how a default parameter value is represented in the URL when the current parameter value is the same as the default value.

We can call these params this way:

// hidden param cannot be passed via url <a href="#/other/fooVal?bar=1&amp;bar=2"> // default foo is skipped <a ui-sref="other({bar: [4,5]})">
