Trigger validation of all fields in Angular Form submit

What worked for me was using the $setSubmitted function, which first shows up in the angular docs in version 1.3.20.

In the click event where I wanted to trigger the validation, I did the following:

vm.triggerSubmit = function() {    vm.homeForm.$setSubmitted();    ...}

That was all it took for me. According to the docs it "Sets the form to its submitted state." It's mentioned here.

I know, it's a tad bit too late to answer, but all you need to do is, force all forms dirty. Take a look at the following snippet:

angular.forEach($scope.myForm.$error.required, function(field) {    field.$setDirty();});

and then you can check if your form is valid using:

if($scope.myForm.$valid) {    //Do something}   

and finally, I guess, you would want to change your route if everything looks good:

$location.path('/somePath');

Edit: form won't register itself on the scope until submit event is trigger. Just use ng-submit directive to call a function, and wrap the above in that function, and it should work.

In case someone comes back to this later... None of the above worked for me. So I dug down into the guts of angular form validation and found the function they call to execute validators on a given field. This property is conveniently called $validate.

If you have a named form myForm, you can programmatically call myForm.my_field.$validate() to execute field validation. For example:

<div ng-form name="myForm">    <input required name="my_field" type="text" ng-blur="myForm.my_field.$validate()"></div>

Note that calling $validate has implications for your model. From the angular docs for ngModelCtrl.$validate:

Runs each of the registered validators (first synchronous validators and then asynchronous validators). If the validity changes to invalid, the model will be set to undefined, unless ngModelOptions.allowInvalid is true. If the validity changes to valid, it will set the model to the last available valid $modelValue, i.e. either the last parsed value or the last value set from the scope.

So if you're planning on doing something with the invalid model value (like popping a message telling them so), then you need to make sure allowInvalid is set to true for your model.
