Ok I try to explain, sorry for my bad english.
I have a form for create a new model, a Supplier, this supplier has many
phones and, in the form, I want to add dinamically as many input fields as
there are the phones to add.
Here is a little piece of the form code:
<span ng-repeat='phone in phones'>
<input type="text" ng-model="phone.number"
name="phones[{{$index}}].number"">
<a href='' ng-click='addPhone()'></a>
<a href='' ng-click='delPhone()'></a>
the angular code is:
$scope.phones = [{name:'phone', number:null}];
$scope.addPhone = function() {
var foundNull;
$scope.phones.forEach( function(phone) {
if (!phone.number) { // if i.number is null
foundNull = true;
}
});
if (!foundNull)
$scope.phones.push({name:'phone'+($scope.phones.length + 1), number:null});
};
$scope.delPhone = function() {
$scope.phones.pop();
};
Now the problem, for those who knows grails, is that there are errors in
the form, then it is render the same form with errors.
When the form is rendered I lost the phones added, that's because
$scope.phones = [{name:'phone', number:null}];
I need a way to maintain the phones added when the form is rendered another
time.
Hope it is clear.
