AngularJS: disabling all form controls between submit and server response

I have a dilemma about what is the best (and correct) approach if I want to disable form controls (or at least make them unavailable for user interaction) during a period of time when user clicks sort of "Save" or "Submit" button and data travelling over the wire. I don't want to use JQuery (which is evil!!!) and query all elements as array (by class or attribute marker) The ideas I had so far are:

• Mark all elements with cm-form-control custom directive which will subscribe for 2 notifications: "data-sent" and "data-processed". Then custom code is responsible for pushing second notification or resolve a promise.
• Use promiseTracker that (unfortunatelly!) enforces to produce extremely stupid code like ng-show="loadingTracker.active()". Obviously not all elements have ng-disabled and I don't want to user ng-hide/show to avoid "dancing" buttons.
• Bite a bullet and still use JQuery

Does any one have a better idea? Thanks in advance!

UPDATED: The fieldset idea DOES work. Here is a simple fiddle for those who still want to do the same http://jsfiddle.net/YoMan78/pnQFQ/13/

HTML:

<div ng-app="myApp">
    <ng-form ng-controller="myCtrl">
        Saving: {{isSaving}}
        <fieldset ng-disabled="isSaving">
            <input type="text" ng-model="btnVal"/>
            <input type="button" ng-model="btnVal" value="{{btnVal}}"/>
            <button ng-click="save()">Save Me Maybe</button>
        </fieldset>
    </ng-form>
</div>

and JS:

var angModule = angular.module("myApp", []);

angModule.controller("myCtrl", function ($scope, $filter, $window, $timeout) {
    $scope.isSaving = undefined;
    $scope.btnVal = 'Yes';
    $scope.save = function()
    {
        $scope.isSaving = true;
        $timeout( function()
             {
                 $scope.isSaving = false;
                 alert( 'done');
             }, 10000);
    };
});

Wrap all your fields in fieldset and use ngDisabled directive like this:

<fieldset ng-disabled="isSaving"> ... inputs ...</fieldset>

It will automatically disable all inputs inside the fieldset.

Then in controller set $scope.isSaving to true before http call and to false after.

There is an simple solution in modern browsers:

1. define a css class

    .disabled {
      pointer-events: none;
      ... ...
    }
   

2. add this class to ng-form

    <ng-form data-ng-class="{ 'disabled': isSaving }"> ... inputs ... </ng-form>
   

Here is the pointer-events support chart.

Note: even if you set pointer-events: none, you can still tab to input element with your keyboard.
