Yeah, have not heard of "bound" form before, but it make sense whatever you
want to call it. More abstractly, I'd call it "maintaining state"... for
your form.
I have a similar case where a user selects values, can go away and come
back to the same page. I use a service to maintain state variables and
share data between controllers in my single page app (meaning I'm not
posting or reloading the page once loaded).
<form>
<input type="text" ng-model="formValues.username">
<input type="text" ng-model="formValues.email">
<button ng-click="resetForm">Reset</button>
</form>
function MyCtrl($scope, StateService){
$scope.formValues = StateService.formValues; //will magically two-way
bind not only to your controller variable but also the state service that
lives for the lifetime of the app
$scope.resetForm = StateService.reset//will happen in service and
controller, and also in UI
}
function StateService(){
var state = {
formValues: { user: null, email: null },
resetToDefaults: function (){
this.formValues.user = 'Dave';
this.formValues = '[email protected]'
}
}
return state;
}
Now if we are talking about reloading the page and maintaining state, then
you'll need to push and pull the values between the controller and the
server, local storage, or cookies. Once again, I'd user a service to call
and get the state from either ajax, storage, or cookies, but same
principals apply.
