AngularJS component not functioning properly due to issues with 'bindings'

.component(
  'testComponent',
 {bindings: {name:'<'},
  template: `{{$ctrl.name}}<br/>
             {{$ctrl.title}}<br/>
             {{test.name}}<br/>
             {{test.title}}<br/>
             {{name}}<br/>
             {{title}}<br/>`,
  controller: function (){
    this.name = 'abc';
    this.title = 'def';
  },
  controllerAs: 'test'
})

This code snippet is used to incorporate a new component into a module. There are total 6 expressions written in the template. Surprisingly, only the second one, $ctrl.title, is functioning correctly while others are not binding properly. Interestingly, when I eliminate name from bindings, then $ctrl.name also starts working as intended. However, according to my knowledge, all 6 expressions should work cohesively.

Can anyone point out what mistake I made?

Answer №1

Explanation: In this scenario, the usage of '<' denotes one-way binding. Where exactly are you implementing this particular component? The name for binding needs to be provided from the location where this component is being invoked. For example:

<test-component>name='abc' </test-component>

This method will function properly while also eliminating 'controllerAs = test'. If you happen to be utilizing $cntrl, it's essential to note that it serves as the default controllerAs attribute of the component and substituting with test may not be necessary.
