Disable button in angular js - angularjs

Question

I have 2 buttons in my page "Save Set" & "Load Set".
"Save Set" button has ng-disabled=isSaveDisabled()
.....
.controller('saveLoadSetToolbarBtn', ['$scope','$modal','propertiesModified',
function ($scope,$modal,propertiesModified) {
$scope.loadTuneSet = function () {
$modal.open({
templateUrl: 'loadSetDlg.html',
controller: 'loadSetCtrl'
});
};
$scope.isSaveDisabled = function() {
return !propertiesModified.get();
};
.......
When I click Load Set, it will open a popup and their I'll have OK button. On this click, I should disable the "Save Set" button
OK Button,
.controller('loadSetCtrl', ['$scope', '$modalInstance', 'generalDataService',
function ($scope, $modalInstance, generalDataService) {
$scope.items = [];
$scope.selectedSet = undefined;
$scope.ok = function () {
//doing some logic
closeDialog();
$modalInstance.close();
};
If any value changes happen in my page then this "Save Set" button will be enabled. problem is if I change any value in my page this button is enabling (as expected). If I click "Load Set" button, popup will open and on OK button click (available on Popup) then this "Save Set" should go back to Disable state. I should be able to return boolean value true through this isSaveDisabled function on OK button click.

Answer 1

Simple:
<button ng-model="btnSaveSet" ng-disabled="btnSaveSet_disabled"
ng-click="btnSaveSet_disabled=true">SaveSet</button>

Answer 2

I think you're trying to code a Modal View, like the Demo of this page : http://angular-ui.github.io/bootstrap/ .
I recommend to try this demo and modify it to fit your needs, because there is not much to change. I try to give you some hints in the comments of the code:
This is the JavaScript Code:
angular.module('ui.bootstrap.demo').controller('ModalDemoCtrl', function ($scope, $modal, $log) {
$scope.items = ['tuneSet', 'tuneSet2','tuneSet3'];
$scope.open = function (size) {
var modalInstance = $modal.open({
templateUrl: 'loadSetDlg.html', // name it like the Template for the Modal
controller: 'loadSetCtrl', // name it like the used controller for the Modal
size: size, // not necessary for you
resolve: {
items: function () { // this will pass in your items into the ModalCtrl
return $scope.items;
}
}
});
modalInstance.result.then(function (selectedItem) { // here is the callback, when the
$scope.selected = selectedItem; // Modal get closed
}, function () {
$log.info('Modal dismissed at: ' + new Date());
});
};
// Here you can implement your logic depending on the user-input that is available on $scope.selected
// it is an object.
console.log($scope.selected); // here you can see it in the console.
});
// Please note that $modalInstance represents a modal window (instance) dependency.
// It is not the same as the $modal service used above.
angular.module('ui.bootstrap.demo').controller('loadSetCtrl', function ($scope, $modalInstance, items) {
$scope.items = items;
$scope.selected = {
item: $scope.items[0] // this will catch the user input (click on link)
};
$scope.ok = function () {
$modalInstance.close($scope.selected.item); // this will pass the chosen tuneSet back to
}; // ModalDemoCtrl
$scope.cancel = function () {
$modalInstance.dismiss('cancel');
};
});
And this is the HTML you need:
<div ng-controller="ModalDemoCtrl">
<script type="text/ng-template" id="loadSetDlg.html">
<div class="modal-header">
<h3 class="modal-title">TuneSet selection!</h3>
</div>
<div class="modal-body">
<ul>
<li ng-repeat="item in items">
<a ng-click="selected.item = item">{{ item }}</a>
</li>
</ul>
Selected: <b>{{ selected.item }}</b>
</div>
<div class="modal-footer">
<button class="btn btn-primary" ng-click="ok()">OK</button>
<button class="btn btn-warning" ng-click="cancel()">Cancel</button>
</div>
</script>
<button class="btn btn-default" ng-click="open()">Open me!</button>
<button class="btn btn-default" ng-click="open('lg')">Large modal</button>
<button class="btn btn-default" ng-click="open('sm')">Small modal</button>
<div ng-show="selected">Selection from a modal: {{ selected }}</div>
</div>
