How can I disable my checkbox from AngularJS input?
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}}"
