change CSS based on value Angularjs - angularjs

Question

I want to change label color and cursor type based on ng-model
index.html
<button ng-click="changeType()">Change</button>
<label class="fee-type" ng-style="feeType ==='one' && {'class':'disabled-class'}" for="fixed2">Client Contengency Fee</label>
<label class="fee-type" ng-style="feeType ==='one' && {'class':'disabled-class'}" for="fixed1">Fixed Fee Per Property</label>
The default class is fee-type but when then button get clicked its class should change to disabled-class
index.css
.fee-type {
float: left;
clear: none;
display: block;
padding: 2px 1em 0 0;
color: black;
}
.disabled-class {
color:gray;
cursor: not-allowed;
}
index.js
$scope.feeType= two;
$scope.changeType= function(){
$scope.feeType=one;
}

Answer 1

You should use ng-class instead of ng-style and add condition in ng-class to apply css class in your label.
HTML:
<button ng-click="changeType()">Change</button>
<label class="fee-type" ng-class="{'disabled-class':feeType ==='one'}" for="fixed2">Client Contengency Fee</label>
<label class="fee-type" ng-class="{'disabled-class':feeType ==='two'}" for="fixed1">Fixed Fee Per Property</label>
and controller
$scope.feeType = 'two';
$scope.changeType = function() {
$scope.feeType = 'one';
};
