Angularjs initial form validation with directives

Question

I have a validation directive called valid-number that is used to set the validity of a form using $setValidity - this works fine for any text values that I type in

You can simply call your verification function during the linking phase, like in this fiddle :

link: function(scope, elm, attrs, ctrl) {                       
    var regex=/\d/;
    var verificationFunction = function(viewValue) {
        var floatValue = parseFloat(viewValue);

        if(regex.test(viewValue)) {
            ctrl.$setValidity('validNumber',true);
            return viewValue;
        }
        else {
            ctrl.$setValidity('validNumber',false);
            return undefined;
        }
    };

    ctrl.$parsers.unshift(verificationFunction);
    verificationFunction();
}
