After setting the input value Array property sum, it displays the value in the input field. However, when submitting the form, the Quantity property is not being received in the Order object. I noticed that if I change the value manually, then the Quantity property value is captured. Is there a way to retrieve the model value from the ng-value attribute?
<input ng-model="Order.Quantity" ng-value="subOrderList.sum('Quantity')" type="number">
In response to your query about the issue of "ng-value not updating Ng-model," it is important to understand that this behavior is intentional. Both ng-value and ng-model were not designed to be used in this particular way.
It seems there may be some confusion regarding your objective, so here are a couple of potential solutions:
If your goal is simply to display a value without user input, you can achieve this without using an input at all. The following examples will both update accordingly:
<span>{{subOrderList.sum('Quantity')}}</span>
<span ng-bind="subOrderList.sum('Quantity')"></span>
However, if you do require user input to update the value, then your HTML should resemble something like this:
<input ng-model="Order.Quantity" type="number">
In such cases, you would need to manually update the value within a controller or service when necessary:
Order.Quantity = subOrderList.sum('Quantity');
Based on your comments, it appears that you might need an input that changes dynamically and sporadically. Without a specific data example or more code, it is difficult to provide a precise solution for this scenario.
