I read through some articles on angular model binding, and just out of curiousity, I was wondering if its possible to bind keys to input too,
http://jsfiddle.net/x3azn/jM28y/4/
so I am hoping ot update the main arr through the input boxes and achieve 2 way key-binding.
Is this possible?
as explained here Binding inputs to an array of primitives using ngRepeat => uneditable inputs, yes you can, but not that way
try this
function ctrl($scope) {
$scope.arr = [{name:'1', lastname: '2'},
{name:'3', lastname: '4'},
{name:'5', lastname: '6'}]
}
<div ng-repeat="person in arr">
<input type="text" ng-model="person.name" />
<input type="text" ng-model="person.lastname" />
</div>
type="text" we have type="url" ?No, it is not possible to bind a key to an input.
The closest thing that I found you can do is abuse ngRepeat's $index property and bind it to the input. You can't change keys for existing values but you can change what value is shown as well as create new key-value pairs. By no means am I recommending this as a solution, I just wanted to share the hackery that ensued when I was investigating this question.
JSFiddle: http://jsfiddle.net/DanielBank/v6tFG/
JavaScript:
function ctrl($scope){
$scope.obj = {
'0': 'a',
'1': 'b',
'2': 'c',
'George': 'Clooney',
};
}
HTML:
<div ng-app>
<div ng-controller="ctrl">
<div ng-repeat="value in obj">
<input type="text" ng-model="$index"/>
<input type="text" ng-model="obj[$index]"/>
<input type="text" ng-model="value"/>
</div>
{{obj}}
</div>
</div>
