I am populating my multiple select like this :
<select ng-model="myAddress" ng-options="address.addressLines for address in search.result.addresses" >
</select>
And there is 2 items currently. But when I load the page it seems to add an extra blank row as such
<option value="?" selected="selected" label=""></option>
But then when I click on my actual 2 item rows the above error row disappears. Any idea what is causing this ?
When the select is initially loaded into the view, the model (myAddress) is not set from the controller. Angular needs a way to represent this, so it adds an empty option to the select box. Once a selection is made, it is populated and gets rid of the empty option because it is not defined in the list that is bound to the select.
If you don't want a blank option to appear, you need to set a valid $scope.myAddress in the controller to be used as the default.
Depending on what you want to accomplish, there are really three options.
Example here:
HTML:
<div ng-app="myApp" ng-controller="MainController">
Select with no value set in controller:<br />
<select ng-model="select1" ng-options="item.name for item in items">
</select> {{select1}}
<br /><br />
Select with value set in controller:<br />
<select ng-model="select2" ng-options="item.name for item in items">
</select> {{select2}}
<br /><br />
Select empty option always available (even after selection):<br />
<select ng-model="select3" ng-options="item.name for item in items">
<option value=""></option>
</select> {{select3}}
</div>
Javascript:
angular.module("myApp", [])
.controller("MainController", function ($scope) {
$scope.items = [
{id: 1, name: "Item 1"},
{id: 2, name: "Item 2"},
{id: 3, name: "Item 3"},
{id: 4, name: "Item 4"}
];
//initial value for select2
$scope.select2 = $scope.items[0];
});
