Assign AngularJS directives to DOM element using controller

I'm experimenting with the idea of controlling the angular directive('ng-show') from the controller.

Here is what I'm attempting to do:

var node = `<div ng-show="this.length > 5">...</div>`;
var child = document.createElement('span');
child.innerHTML = node;
document.querySelector('.container').appendChild(child);

Is it a valid approach to set the directive on a DOM Node before it is added to the DOM Tree?

Answer №1

To dynamically add HTML with Angular directives to your HTML page, you can utilize the $compile service provided by AngularJS. Here is an example of how you can achieve this:

app_module.controller('appController', function ($scope, $compile) {
   var node = `<div ng-show="this.length > 5">...</div>`;
   var child = document.createElement('span');
   child.innerHTML = node;
   $compile(document.querySelector('.container').appendChild(child))($scope);
});

By using the $compile service, AngularJS will re-compile the template and recognize the newly added ng-show directive.
