Ways to set control values with AngularJS

After retrieving a single record from the database for my detail view, I need to assign data to controls. Take a look at my code snippet below:

  var app = angular.module("MyProductApp", []);
        app.controller("ProductsController", function ($scope, $http) {
            var ProductID = @Html.Raw(Json.Encode(ViewData["ProductID"]));
            $http.get('/api/Products/GetProductForEditOrDetail',{params: { ProductID : ProductID }}).
            success(function(data){
                $scope.Product = data;
            }).
            error(function(data){
                alert("msg");
            });
        });

And here is the corresponding HTML code:

<div ng-app="MyProductApp" class="form-horizontal">
    <div ng-controller="ProductsController">
        <h4>Product</h4>
        <hr />
        <div class="form-group" >
            <label class="control-label col-md-2">Product Name</label>
            <div class="col-md-10">

                <input id="txtProductName" type="text" class="form-control" name="txtProductName" disabled="disabled" Value="{{Product.ProductName}}" />
                <input id="hdnProductID" type="hidden" class="form-control" name="hdnProductID" value="{{Product.ProductID}}" />
                <input id="hdnCategoryID" type="hidden" class="form-control" name="hdnCategoryID" value="{{Product.CategoryID}}" />
            </div>
        </div>
</div>
</div>

Answer №1

To effectively handle data binding in AngularJS, it is recommended to leverage the ngModel directive.

By utilizing the ngModel directive, you can easily connect an input, select, textarea, or even a custom form control to a specific property on the scope through NgModelController, which is generated and made available by this directive.

<input ng-model="User.Name" />

Answer №2

If you're searching for the solution, ngModel is the key - make sure to check out the documentation !

Answer №3

If you need to pass a value using hidden fields, you cannot use ng-model. Instead, consider using ng-value in this scenario.

<input id="hdnCategoryID" type="hidden" class="form-control" name="hdnCategoryID" ng-value="Product.CategoryID" />
