How can I disable my checkbox from AngularJS input?

Question

<div ng-repeat="x in spaceutilization">
  <input type="checkbox" name="{{x.filenumber}}" id="{{x.id}}" class = "pdffiles" value="101SP{{x.initials}}.dwg" /><label for="{{x.id}}"><button type = "button" class = "btn btn-primary btn-sm hidden-sm hidden-xs"> PDF</button></label><br />
</div>

I need to be able to add something to this snippet that disables the input checkbox based on another AngularJS input such as {{x.status}}. I tried simply doing:

<input type="checkbox" name="{{x.filenumber}}" id="{{x.id}}" class = "pdffiles" value="101SP{{x.initials}}.dwg" {{x.status}} />

Where status:'disabled' but that gave an output of

{{x.status}}=""

within the input element...which I don't understand why at all. But it seemed like the simplest route.

You can't add attributes dynamically using Interpolation method to your html tag. In your case you can simply do ng-disabled="x.status" — Rahil Wazir

You need to use ng-disabled="expression" directive, on basic of expression evaluation value it add disabled attribute to that element.Also for better attribute values evaluation you could use ng-attr directive

Markup

<input type="checkbox" ng-attr-name="{{x.filenumber}}" ng-attr-id="{{x.id}}" class ="pdffiles" 
value="101SP{{x.initials}}.dwg" ng-disabled="x.status == 'disabled'"/>

If x.status does return a bool value then you could directly used ng-disabled="{{x.status}}"

do you mean {{x.status}} == 'disabled' ? Also, what would status equal? What if I don't what the checkbox disabled?

Using @Rahil Wazir's comment above, I did ng-disabled="{{x.status}}" where status:'true' or status:'false"

@Christine268 hey don't use interpolation with ng-disabled directive, ng-disabled directive is matured enough to evaluate scope variables, It must be ng-disabled="x.status" if x.status has boolean

@pankajparker when I change it to ng-disabled="x.status" it no longer works. status either equals true or false. ng-disabled="{{x.status}}" is what's working for me.
