基本的AngularJS表单验证不起作用

Question

I'm using basic example from W3School and trying to validate AngularJS form. But in any browser form is not getting validated. Any suggestions on the same?

<form name="myForm" novalidate>

    <p>Username:<br>
        <input type="text" name="user" ng-model="user" required>
        <span style="color:red" ng-show="myForm.user.$dirty && myForm.user.$invalid">
            <span ng-show="myForm.user.$error.required">Username is required.</span>
        </span>
    </p>

    <p>Email:<br>
        <input type="email" name="email" ng-model="email" required>
        <span style="color:red" ng-show="myForm.email.$dirty && myForm.email.$invalid">
            <span ng-show="myForm.email.$error.required">Email is required.</span>
            <span ng-show="myForm.email.$error.email">Invalid email address.</span>
        </span>
    </p>

    <p>
        <input type="submit" ng-disabled="myForm.user.$dirty && myForm.user.$invalid ||  myForm.email.$dirty && myForm.email.$invalid">
    </p>

</form>

You have to include ng-app and ng-controller to your form. also declare the app and controller in a separate js file.
