AngularJS Form Validation - Forcing Validation on Submit

An example of how to force AngularJS to validate after submitting... or at least look like it!

HTML

<link rel="stylesheet" href="//netdna.bootstrapcdn.com/twitter-bootstrap/2.3.1/css/bootstrap-combined.min.css">
<form >

<input type="text" name="email" id="email">
<input type="button" onclick="validate()">
</form>

JavaScript

function ValidateEmail(mail)   
{  
var mailformat = /^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/;  
// if (/^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/.test(myForm.emailAddr.value))  
if(mail.match(mailformat))
  {  alert(mail);
    return (true)  
  }  
    alert("You have entered an invalid email address!")  
    return (false)  
}  

function validate()
{
var data=document.getElementById("email").value;
checkNumberorEmail();

}
function phonenumber(inputtxt)  
{  
  var phoneno = /^\d{10}$/;  
  if((inputtxt.match(phoneno)))  
        {  
		alert(inputtxt);
      return true;  
        }  
      else  
        {  
        alert("enter 10 digit number");  
        return false;  
        }  
}  


function checkNumberorEmail()
{
  var data=document.getElementById("email").value;
  if (isNaN(data)) 
  {
    ValidateEmail(data)   ;
   
  }
  else{
  phonenumber(data) 
  }
}
