I don't know what you precisely want to do but if you only want do one http request you can perhaps use angular ui router with something like
$stateProvider
.state('main', {
url: "/",
templateUrl: "main.html"
})
.state('about', {
url: "/about",
templateUrl: "main.html",
controller: function($scope) {
$scope.showDiv = "true";
}
})
That way you can switch state and because everything you need is already loaded, nothing gets loaded anymore. Or perhaps you can also use parameters.
But why is it so bad to have one additional request? That would be something interesting to know! :)
EDIT: The easy approach with $location
(https://docs.angularjs.org/guide/$location)
index.html:
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Example</title>
<base href="/">
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.3.1/angular.min.js"></script>
<script src="app.js"></script>
</head>
<body ng-app="html5-mode">
<div ng-controller="LocationController">
<button ng-click="changeUrl()">Change url</button>
</div>
</body>
</html>
app.js:
angular.module('html5-mode', [])
.controller("LocationController", function ($scope, $location) {
$scope.$location = {};
$scope.changeUrl = function () {
// https://docs.angularjs.org/guide/$location
console.log("The current path: " + $location.path());
console.log("Changing url...");
$location.path('/newValue')
};
})
.config(function ($locationProvider) {
$locationProvider.html5Mode(true).hashPrefix('!');
})
Be sure to set the basePath correct.
