Suppose you are using routes:

// bootstrap
myApp.config([\'$routeProvider\', \'$locationProvider\', function ($routeProvider, $locationProvider) {

    $rout

    Routes monitor the $location service and respond to changes in URL (typically through the hash). To "activate" a route, you simply change the URL. The easiest way to do that is with anchor tags.

    <a href="#/home">Go Home</a>
<a href="#/about">Go to About</a>

    Nothing more complicated is needed. If, however, you must do this from code, the proper way is by using the $location service:

    $scope.go = function ( path ) {
  $location.path( path );
};

    Which, for example, a button could trigger:

    <button ng-click="go('/home')"></button>

    Another solution but without using ng-click which still works even for other tags than <a>:

    <tr [routerLink]="['/about']">

    This way you can also pass parameters to your route: https://stackoverflow.com/a/40045556/838494

    (This is my first day with angular. Gentle feedback is welcome)

    You can use:

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

    If you want some dynamic variable inside href you can do like this way:

    <a ng-href="{{link + 123}}">Link to 123</a>

    Where link is Angular scope variable.

    I used ng-click directive to call a function, while requesting route templateUrl, to decide which <div> has to be show or hide inside route templateUrl page or for different scenarios.

    AngularJS 1.6.9

    Lets see an example, when in routing page, I need either the add <div> or the edit <div>, which I control using the parent controller models $scope.addProduct and $scope.editProduct boolean.

    RoutingTesting.html

    <!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Testing</title>
    <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
    <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular-route.min.js"></script>
    <script>
        var app = angular.module("MyApp", ["ngRoute"]);

        app.config(function($routeProvider){
            $routeProvider
                .when("/TestingPage", {
                    templateUrl: "TestingPage.html"
                });
        });

        app.controller("HomeController", function($scope, $location){

            $scope.init = function(){
                $scope.addProduct = false;
                $scope.editProduct = false;
            }

            $scope.productOperation = function(operationType, productId){
                $scope.addProduct = false;
                $scope.editProduct = false;

                if(operationType === "add"){
                    $scope.addProduct = true;
                    console.log("Add productOperation requested...");
                }else if(operationType === "edit"){
                    $scope.editProduct = true;
                    console.log("Edit productOperation requested : " + productId);
                }

                //*************** VERY IMPORTANT NOTE ***************
                //comment this $location.path("..."); line, when using <a> anchor tags,
                //only useful when <a> below given are commented, and using <input> controls
                $location.path("TestingPage");
            };

        });
    </script>
</head>
<body ng-app="MyApp" ng-controller="HomeController">

    <div ng-init="init()">

        <!-- Either use <a>anchor tag or input type=button -->

        <!--<a href="#!TestingPage" ng-click="productOperation('add', -1)">Add Product</a>-->
        <!--<br><br>-->
        <!--<a href="#!TestingPage" ng-click="productOperation('edit', 10)">Edit Product</a>-->

        <input type="button" ng-click="productOperation('add', -1)" value="Add Product"/>
        <br><br>
        <input type="button" ng-click="productOperation('edit', 10)" value="Edit Product"/>
        <pre>addProduct : {{addProduct}}</pre>
        <pre>editProduct : {{editProduct}}</pre>
        <ng-view></ng-view>

    </div>

</body>
</html>

    TestingPage.html

    <!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <style>
        .productOperation{
            position:fixed;
            top: 50%;
            left: 50%;
            width:30em;
            height:18em;
            margin-left: -15em; /*set to a negative number 1/2 of your width*/
            margin-top: -9em; /*set to a negative number 1/2 of your height*/
            border: 1px solid #ccc;
            background: yellow;
        }
    </style>
</head>
<body>

<div class="productOperation" >

    <div ng-show="addProduct">
        <h2 >Add Product enabled</h2>
    </div>

    <div ng-show="editProduct">
        <h2>Edit Product enabled</h2>
    </div>

</div>

</body>
</html>

    both pages - RoutingTesting.html(parent), TestingPage.html(routing page) are in the same directory,

    Hope this will help someone.

    just do it as follows in your html write:

    <button ng-click="going()">goto</button>

    And in your controller, add $state as follows: 

    .controller('homeCTRL', function($scope, **$state**) {

$scope.going = function(){

$state.go('your route');

}

})

    Using a custom attribute (implemented with a directive) is perhaps the cleanest way. Here's my version, based on @Josh and @sean's suggestions.

    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);
                });
            });
        }
    }
}]);

    It has some useful features, but I'm new to Angular so there's probably room for improvement.
