I want to disable select option which is in loop. So far i have implemented in following link. Its working way I wanted but i have made code very long. Is there any other way to implement.
<div ng-controller="OptionsController">
<button value="add" ng-click="add()">
add
</button>
<div ng-repeat="val in v">
<select ng-model="val.myColor" ng-change="call(c.name)">
<option ng-repeat="c in colors" ng-disabled="c.shade=='dark'" value="{{c.name}}">
{{c.name}}
</option>
</select>
</div>
</div>
ng-options with disabled rows has some details on how to use ng-options with disabled options.
Based on your current use of the ng-repeat: http://jsfiddle.net/rhz8hxL5/1/
<div ng-controller="OptionsController">
<button value="add" ng-click="add()">
add
</button>
<div ng-repeat="val in v">
<select ng-model="val.myColor" ng-change="call()">
<option ng-repeat="c in colors" ng-disabled="isDisabled(c)" value="{{c}}">
{{c}}
</option>
</select>
</div>
</div>
JS - I simplified it a bit for clarity in demonstration
angular.module('myApp', [])
function OptionsController($scope, $timeout) {
$scope.v = [{
myColor: 0
}];
$scope.inUse = [];
$scope.isDisabled = function(name) {
return $scope.inUse.indexOf(name) !== -1;
}
$scope.colors = ['black', 'white', 'red', 'blue', 'yellow'];
$scope.add = function() {
$scope.v.push({});
}
$scope.call = function() {
$scope.inUse = [];
for(var i=0; i<$scope.v.length; i++) {
var val = $scope.v[i];
$scope.inUse.push(val.myColor);
}
}
}
In English:
The $scope.inUse
array is maintaining a list of currently selected values. When you change a dropdown value it invokes the call
function. That function empties the $scope.inUse
array and re-populates it with the currently selected values.
The $scope.isDisabled
function returns a boolean on the basis that "If it has an index it is in use and thus disabled"
