Establish AngularJS Model Using HTML Element

Currently, I am working on a project with django and angular. My goal is to have django populate a value in the HTML template and then instruct Angular to use that value as the initial value for a model.

There are two main reasons I need this:

Simplicity - The page does not currently utilize Angular, and I believe it would be easier to transition by implementing this approach.
SEO - Some search engines struggle to read values that are populated in the DOM through Angular. While there are SEO solutions available for Angular, I am hoping there might be a simpler way?

I would greatly appreciate any assistance or insights you can provide :)

Answer №1

Start your model based on the initial HTML value given.

For example, your HTML code could look like this:

<div ng-bind="value">initialValue</div>

And in your controller:

var elem = $( 'get the element' );
$scope.value = elem.text();

Angular will then handle any changes made to $scope.value.

The drawback is having to select the element (jQuery used here for simplicity but vanilla JavaScript can also be used).

An alternative solution would be a custom directive:

<div late-binding="value">initialValue</div>

I'll leave the directive implementation as an exercise for you, unless you require assistance with it :)
