How can I put multiple values for ng-disabled in angular js?

问题

My problem is explained with this following JS fiddle: http://jsfiddle.net/FJf4v/10/

    <div ng-app>
<div ng-controller="myCnt">

    <h3>A ->> <input type="checkbox" ng-model="check"> </input></h3>
    <h3>B ->> <input type="checkbox" ng-model="check"> </input></h3>  

    <br/>
    <input type="checkbox" ng-disabled="check">Chkbox1 to be disabled</input>
    <input type="checkbox" ng-disabled="check">Chkbox2 to be disabled</input>
    <hr/>
</div>
</div>

Javascript:
function myCnt($scope) {
//
}

In this fiddle, there are total 4 check boxes labeled as A, B, Chkbox1 and Chkbox2. What I am looking for is to disable both chkbox1 and chkbox2 after checking one of A and B checkboxes. However, its done halfway. If you click on either A or B, both these buttons are getting checked and below chkboxes are getting disabled. But, I dont want to get checked both A and B checkboxes if I just click on any one of them.

I hope, you will get my question.

Thank you !!

So, as I said in the comments, if you want to achieve this with a very long list of checkboxes, you can try this way : (yeah for this example "very long" means 10)

The models
You can use a simple object which will contain all the values of the checkboxes, I did this using a ng-repeat, but it could be anything, just use the same iterable object :

<input type="checkbox" ng-repeat="nb in [1,2,3,4,5,6,7,8,9,10]" ng-model="checkModels[nb]" /></h3>

This object is initialized in the controller, I didn't specify any value, but you could for example set some checkboxes here :

$scope.checkModels={};

The disabling function
Nothing very difficult here, instead of a long list of || values, we will iterate through the models and return true as soon as we find a checked box :

    $scope.isThisDisabled=function(){
     for(var i in $scope.checkModels)
     {
         if($scope.checkModels[i])
             return true             
     }
    return false;
}

Then, we can use this function in the HTML :

<input type="checkbox" ng-disabled="isThisDisabled()">Chkbox1 to be disabled</input>

The modified fiddle to test this : http://jsfiddle.net/DotDotDot/FJf4v/12/

Have fun

Use two seperate variables i.e checkA and checkB. Then for ng-disabled use the logical OR operator like this:

ng-disabled="checkA || checkB"

I think this is what you are trying to achieve...?
