I try to make a version of "tic tac toe" with AngularJS and be as minimalistic as possible. The only solution for my problem is to assign every button a unique ID (f+i).
HTML
<table>
<tr ng-repeat="f in [5,10,15]">
<!-- numbers chosen for unique combos-->
<td ng-repeat="i in [0,1,2]">
<button ng-click="toTrue()" >
<div >
{{getXO()}}
</div>
</button>
</td>
</tr>
</table>
JavaScript
$scope.XObool=false;
$scope.toTrue = function() {
if(!$scope.XObool){
$scope.XObool=true;
}
else if($scope.XObool) {
$scope.XObool=false;
}
};
$scope.getXO = function(){
if($scope.XObool){
return 'X';
}
else {
return 'O';
}
};
ng-repeat gives you several variables to work with, namely $index. In your case you'll want something like:
<button id="{{$index}}" ...>
More info on the ng-repeat docs.
Second Option
Use the f and i variables to create unique IDs.
<table ng-app>
<tr ng-repeat="f in [5,10,15]" data-id="{{$index}}">
<td ng-repeat="i in [0,1,2]">
<button id={{'id' + (i+f)}} ng-click="toTrue()">
{{'id'+(i+f)}}
</button>
</td>
</tr>
</table>
Here's a demo.
