i am using angularjs' form stuff to gather user information. to get time i user <timpicker> it seems that this field is not set (ng-model of timepicker is null) if i call my ng-submit="submit()".
The only way i found so far is to call ng-change in timepicker and set a viable in scope which is then used in submit. Beside the fact that this is ugly, the main problem is if the user doesn't change the value (default is now) i don't have a time.
Is there a way to gather all ng-model variables in $scope on form's "ng-submit"?
EDIT It is not a problem of form its problem of timepicker. As soon as i change the time once the model gets filled (without the need of change method)
It will gather all ng-model variables on $scope that are set on input fields within the form. If you want to add a variable to your form without actually showing it on the screen, you can do:
<input type="hidden" ng-model="yourVariable" />

I'm currently maintaining an AngularJS application and need to have html inputs use the ngRequired directive. However these inputs do not use ngModel-- just straight up value to display the value dynamically and ngClick to popup a modal window that will eventually set the value in an object that is not bounded to a model. Seems like ngRequired only works when paired with ngModel in order for the submit button to reflect changes appropriately (like enable/disable).
I tried to work around not using ngRequired by manipulating the ngInvalid CSS which works great for showing the required fields-- however it does not bubble up to the submit button (disabling it if one or more required fields have no input). Is there a way to emulate ngRequired without using it explicitly in AngularJS?
I am using $dirty to check the changes in a form ,but if i type something in the input box and remove it, the $dirty is still true.Is there any solution or it will work like this.
That is by design. Any form becomes $dirty whenever the user interacts with it, and you cannot undo the interaction event. Though you can restore defaults, that is clearly not the same.
Consider using $watch to check whether new value is different from the default one, and $setPristine() to clear user input.
$dirty means The field has been modified one more time. for compare your model by your previous model you can use $watch in controller.
if your field is empty you have a solution must set required attribute and in your input tag and use below code set ng-validate of your form to novalidate and then use below code for compare:
formName.inputName.$dirty && formName.inputName.$error.required
$Dirty refers to the form field is modified and you want to check using $pristine
I am Struggle With Dynamic Form Validation In My Current Project, in my Form Having Two Fields like User Name and Email, Both Are Mandatory.
If User Click Add-More(Up to 2 times only) Button Then Same above fields are came. those two fields are also Mandatory. if user removes those fields validation will not be work
I Already Wrote those 2 fields(3 times) just, I Kept ng-hide and ng-show,
And My Code is below,
enter code here
I have Added My Code To Plunker:

Avoid to use ng-hide or ng-show.
Prepare on model i.e. JSON Array and bind using ng-repeat and write associated code in JavaScript.
Example: Click here for Example
Use ng-required="showUser2" instead of just required.
In an AngularJS-form a field is still required even when its hidden.
That means when you hide your required form input field with ng-hide or ng-show then the AngularJS FormController completeProfile still treats the form as $invalid.
To get dynamic forms how you want them you can use ng-if to hide your unwanted input fields. Input fields inside of a ng-if are not considered by the form validation logic.
I updated your Plunker. The submit button is only shown when the form is valid.
I would like to use the angular x-editable directive to work with a text field per the following
(a) I don't want to display buttons. I tried the buttons=no option but it does not seem to work with input of type text.
See the fiddle here.
(b) I want the underlying ng-model property to update immediately with each keystroke , without waiting for the user to focus out of the input. (as is default behavior with vanilla angular, eg. <input type=text ng-model="somepropertyname" />
How can one achieve (a) and (b) with angular x-editable? link to fiddle
Answer to 1(a) is to add the blur="submit" attribute (in addition to buttons="no")
Is ng-model allowed inside element of a table? Will angular automatically update the model if I change a particular column(i.e. view)?
If you are making the table cells directly editable using the HTML contenteditable attribute, ng-model won't work automatically as by default it's only for form elements.
It is possible to make it work with contenteditable though. There is an working example of how to do it on the angular website at http://docs.angularjs.org/api/ng.directive:ngModel.NgModelController
ng-model is allowed wherever typical form elements exist that can use the directive (input, select and textarea)
One thing I will say about ng-model that can make it a bit tricky is that you will want to bind ng-model to a property of an object rather than just a simple scope variable. I have run into several instances where I bind $scope.foo to ng-model and use it in an input control. Then, if you clear the input field, the binding is lost and it stops updating the variable. Use something like $scope.fooObj.modelProp where fooObj is an object and it will work fine.
