Angular JS binding scope data within ng-repeat to form - angularjs

Question

I have a collection of items in $scope.data with fields "id","name" & "age", that are being displayed in the view using ng-repeat directive.
For each set of items, there is a corresponding "edit button".
I want to be able to access values for the particular set of items for which edit button was pressed.
Html:
<div ng-controller="Ctrl">
<div ng-repeat="i in data">
Name: {{i.name}}
Age: {{i.age}}
<form ng-submit="submit()">
<input type="text" ng-model="i.id"/>
<input type="submit" value="Edit" />
</form>
</div>
</div>
Script:
function Ctrl($scope)
{
$scope.data = [
{id:1,name:"Alex",age:22},
{id:2,name:"Sam", age:28}
];
$scope.submit = function() {
//access id of user for which edit was clicked
};
}
What is the right way to do this?

Answer 1

Instead of a form, I would suggest you just use a button:
<div ng-controller="Ctrl">
<div ng-repeat="i in data">
Name: {{i.name}}
Age: {{i.age}}
<input type="text" ng-model="i.id"/>
<button ng-click="submit(i)">Edit</button>
</div>
</div>
Just send i into the button click event (I suppose you could use form if you need validation, but your example doesn't seem to need it).
Your submit function then changes to:
$scope.submit = function(selectedItem) {
// here you now have access to selected item
};

Try this:
HTML:
<form ng-submit="submit(i.id)">
JavaScript:
$scope.submit = function(userId) {
// you have userId
};

Answer 3

One option is to just use an ng-click within a button that calls your submit passing in i
<div ng-controller="Ctrl">
<div ng-repeat="i in data">
Name: {{i.name}}
Age: {{i.age}}
<button ng-click="submit(i);">edit</button>
</div>
</div>
and the function:
$scope.submit = function(i) {
console.log(i);
//access id of user for which edit was clicked
};
Here's a fiddle of that working: http://jsfiddle.net/pRAcP/
