Angular JS Tutorial: How to Nest ng-views

When merging two separate Angular apps into one, I encountered the need to nest ng-views. The structure of my sample code (index.html) looks like this:

<!doctype html>
<html lang="en" ng-app="myApp">
<head>
<meta charset="utf-8">
<title>My AngularJS App</title>
<link rel="stylesheet" href="css/app.css"/>
</head>
<body>
<ul class="menu">
<li><a href="#/view1">view1</a></li>
<li><a href="#/view2">view2</a></li>
</ul>

<div ng-view></div>

<div>Angular seed app: v<span app-version></span></div>

<script src="lib/angular/angular.js"></script>
<script src="js/app.js"></script>
<script src="js/services.js"></script>
<script src="js/controllers.js"></script>
<script src="js/filters.js"></script>
<script src="js/directives.js"></script>
</body>
</html>

The view from one of my apps (view2.html) is as follows:

<div class="ng-view"></div>
<p>This is the partial for view 1.</p>
{{ 'Current version is v%VERSION%.' | interpolate }}

Even with these changes, when trying to load the page with nested views again, it is not working. Is it possible to nest ng-views within Angular applications? If not, can someone provide an explanation?

Answer №1

Updated answer:

When it comes to handling complex routing in AngularJS, many developers turn to UI Router. You can find more information about UI Router here: https://angular-ui.github.io/ui-router/site/#/api/ui.router


Original answer:

Currently, AngularJS does not support nesting views natively. To work around this limitation, I implemented a solution inspired by the one discussed here:

This allowed me to efficiently nest views without relying solely on ng-view.

However, I later came across what I consider to be a simpler and superior solution at (look for "Route Checking" section).

Give it a try!

Answer №2

If you're looking for a better way to handle application states in AngularJS, I recommend checking out the ui-router project developed by the AngularUI team. This innovative router is state-based and offers improved URL reactivity, as well as support for multiple and nested views.

I once had a similar question myself and found some helpful insights here: How do I setup nested views in AngularJS?

It's worth noting that ui-router is likely to be integrated into future versions of AngularJS, so embracing it now could save you from having to rely on other routing solutions down the road. Why wait for tomorrow when you can access cutting-edge features today? :-)

Answer №4

When it comes to handling nested views and routing, there are various third-party libraries available. While ui-router is a popular choice, I would like to introduce you to another option:

This library offers the exact nested views capabilities you're looking for, in a much simpler manner compared to ui-router. Here's an example using this library:

index.html:

<div app-view-segment="0"></div>

view1.html:

<p>This is the partial for view 1.</p>
<div app-view-segment="1"></div>

deep-view.html:

<p>This is the partial for view inside view1.</p>  

Answer №5

If you're not keen on relying on another library to solve your issue (which is totally fine), consider exploring the use of directives as well as ng-switch and ng-show.

This suggestion was shared in response to a question found here:

angular complex nesting of partials

Answer №6

I have my doubts about whether this approach aligns with Angular best practices (especially considering the potential cross-browser issues mentioned earlier), but I came up with a solution using `ng-include` to create an "all" view containing nested views within an `all.html` file:

    <div class="all" ng-include src="'views/foo.html'" ng-controller="FooCtrl">
    </div>

    <div class="all" ng-include src="'views/bar.html'" ng-controller="BarCtrl">
    </div>

    <div class="all" ng-include src="'views/baz.html'" ng-controller="BazCtrl">
    </div>

While this approach worked for me, it did feel somewhat unconventional within the framework. I am considering exploring alternatives like the one Eamon shared in the future.
