I am using a fuelUX Wizard and Angularjs. I would like the next button to be enabled or disabled basing on this controller method:
$scope.canMoveForward = function(){
switch($("#moduleWizard").wizard("selectedItem").step){
case 1:
//check if the module on the first step is valid*/
return $scope.validSelection && $scope.linkedPredicateForm.$valid;
case 2:
//check if the table is empty
return !linkingDataSource.isEmpty();
case 3:
var enab= ($scope.saveModeForm.$valid && $scope.newSourceForm.$valid) ||
($scope.saveModeForm.$valid && $scope.appendSourceForm.$valid)
}
};
So indeed this is how I decleared the buttons:
<div class="actions">
<button class="btn btn-mini btn-prev" ng-click="refresh()"> <i class="icon-arrow-left"></i>Prev</button>
<button class="btn btn-mini btn-next" data-last="Finish" id="wizard-next" ng-disabled="!canMoveForward()"
ng-click="handleStepResult()">
Next<i class="icon-arrow-right"></i></button>
</div>
And it works fine, except when I get back from the second page to the first page: if the next button is disabled in the second page it will be this way even on the first page, unless I don't edit the form there. Is there anyway to refresh the ng-disabled binding?
I guess AngularJS cannot check if the output of canMoveForward()
has changed or not. I found that for this kind of things it's easier to rely on scope variables. You could do something like this:
ng-disabled="!canMoveForward"
Then in your controller just set the property to true/false as needed:
$scope.canMoveForward = false;
