A shim for your pleasure, so that in case you have to attach Angular model directives to form fields (without clearing the initial value) that are also being used in .NET WebForms.
angular.module('MyApp', [])
.run(function () {
var d = document.querySelectorAll('input[type="text"]');
for (var i = d.length; i-- > 0;) {
var e = d[i];
if (e.hasAttribute('ng-model') && e.value != null && e.value != 0) {
var model = e.getAttribute('ng-model');
