Try this:
var categorytitle = '';
$log.log('vm.usertype', vm.usertype);
switch (vm.usertype) {
case 'Farmer':
categorytitle = 'Enter coconut type';
break;
case 'Worker':
categorytitle = $translate.instant('{{"venterworktype_message" | translate}}');
break;
case 'Buyer':
categorytitle = $translate.instant('{{"venterproduct_message" | translate}}');
break;
case 'Group':
categorytitle = $translate.instant('{{"wtype_message" | translate}}');
break;
case 'Expense':
categorytitle = $translate.instant('{{"newexpensetype_message" | translate}}');
break;
}
var myPopup = $ionicPopup.show({
template: '<input focus-me type="text" ng-model="data.expensetype" limit-char limit="15">',
//title: $translate.instant('{{"penterexpensetype_message" | translate}}'),
title: categorytitle,
scope: $scope,
buttons: [
{ text: $translate.instant('{{"pcancel_message" | translate}}') },
{
text: $translate.instant('{{"psave_message" | translate}}'),
type: 'button-positive',
onTap: function (e) {
if (!$scope.data.expensetype) {
//don't allow the user to close unless he enters producttype
e.preventDefault();
} else {
addExpenseCategory();
return $scope.data.expensetype;
}
}
},
]
});
myPopup.then(function (res) {
$log.log('Tapped!', res);
});
