How can I access form.submit from angular controller ?

Answer 1

I suggest you to use ng-submit directive on your form. From there you may return true/false after your validation.

Controller

app.controller('mainController', function($scope) {
  $scope.submit = function(user) {
    var isvalid = true;

    // Add your code 
    // for server validation here

    if (isvalid) {
        return true;
    }
    return false; //failed
  }
});

Html

<form name="userForm" ng-submit="submit(user)">
    <input type="text" ng-model="user.email" />
    <input type="text" ng-model="user.password" />
    <button type="submit">Submit</button>
</form>

Suppose on ng-click you call,

validate();

In this function u can do validation and form submission action as follows( my syntax may not be correct....but I'am just trying to convey my idea)

$scope.vaidate = function(input) { 

    //Add your validation code here, it includes api call etc.

    // If validation succeeds, run code for submitting the form. 
    if() // add validation success condition
    {
         //run code for submitting the form.
    }
    else
    {
         // Add code to show error message within the html form.
    }

}

I think you can run submit action within the if condition.

I have fixed it by using jquery to select form with method submit

$("#myForm").submit();

It work fine for me !!!
