Using multiple ng-controller directives with the "controller as x" syntax on a single element

  1. What is the reason that Angular does not allow two ng-controller directives on a single element and
  2. What are some potential solutions for this issue - such as using custom directives or nesting HTML elements with a single ng-controller directive, among other options

For example:

<div ng-controller="ControllerOne as c1" ng-controller="ControllerTwo as c2">
    {{ c1.value }}, {{ c2.value }}
</div>

Check out this JSFiddle example demonstrating setting two controllers on the same element.

Answer №1

It is impossible to have two isolated scopes on the same element because ng-controller creates an isolated scope for the current element.

To correct this issue, modify your code as follows:

<div ng-controller="ControllerOne as c1">
    <div ng-controller="ControllerTwo as c2">
        {{ c1.value }}, {{ c2.value }}
    </div>
</div>

Furthermore, it is invalid to use the same name attribute in any HTML tag.
