Here’s a simple jQuery code snippet to check if a string is either a phone number or email address. It could be very useful for checking form validation. You can then have a input called “Email or Phone” then on submit check the value and if its a phone number then set value to the phone input and clear email input before form submit.
jQuery Code
//validate name
var name = $('input[name="name"]').val();
if (name.length < 3)
{
alert('Please enter a name 3 characters or more.');
return false;
}
//validate email
var email = $('input[name="email"]').val(),
emailReg = /^([w-.]+@([w-]+.)+[w-]{2,4})?$/;
if(!emailReg.test(email) || email == '')
{
alert('Please enter a valid email address.');
return false;
}
//validate phone
var phone = $('input[name="phone"]').val(),
intRegex = /[0-9 -()+]+$/;
if((phone.length < 6) || (!intRegex.test(phone)))
{
alert('Please enter a valid phone number.');
return false;
}
[/js]
Phone or email
[js]
//check if they entered a phone number OR email address
var ep_emailval = $('#email').val();
var intRegex = /[0-9 -()+]+$/;
if(intRegex.test(ep_emailval)) {
console.log("is phone");
//copy value to phone field
$('#phone').attr('value',ep_emailval);
//clear email field
$('#email').attr('value','');
}
HTML Code
//check if they entered a phone number OR email address
