In order for ASP.NET MVC to correctly bind a list of items on a form post, the name attribute has be along the lines of
name='Show.Days[0].OpenHour'
name='Show.Days[1].OpenHour'
The user can enter the number of days the show will be into a form field, which then updates the model and the ng-repeat. I'd like to be able to insert the appropriate index into the name field, something like
name='Show.Days[$index].OpenHour'
Is this possible with angular?
Use name="Show.Days[{{$index}}].OpenHour". With this, AngularJS evaluates $index and replaces it with the correct value.
It seems that you forgot to wrap the expression with {{ and }} in the view. Do you need something like this?
var app = angular.module('myApp', []);
app.controller("myCtrl", function ($scope) {
$scope.Show = {
Days: [
{OpenHour: '8am'},
{OpenHour: '10am'}
]
};
});<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.8/angular.min.js"></script>
<div ng-app="myApp">
<div ng-controller="myCtrl">
<div ng-repeat="day in Show.Days">
<input type="text" ng-model="Show.Days[$index].OpenHour" name="{{Show.Days[$index].OpenHour}}">
</div>
</div>
</div>or like this?
var app = angular.module('myApp', []);
app.controller("myCtrl", function ($scope) {
$scope.Show = {
Days: [
{OpenHour: '8am'},
{OpenHour: '10am'}
]
};
});<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.8/angular.min.js"></script>
<div ng-app="myApp">
<div ng-controller="myCtrl">
<div ng-repeat="day in Show.Days">
<input type="text" ng-model="Show.Days[$index].OpenHour" name="Show.Days[{{$index}}].OpenHour">
</div>
</div>
</div>
name="{{Show.Days[$index].OpenHour}}"
