How to pass an attribute instead of the selected value in a dropdown

I would like to pass the email attribute in the testEmail variable but it is passing the name John Doe

<option value="2" email="[email protected]">John Doe</option>
var testEmail = $("#nameofDropdown option:selected").text();
var email = promt("Enter an email to send to", testEmail );

I know it has to do with this line option:selected just not sure what to change it to to get the email.

Answer

Use .attr() rather than .text()

$("#nameofDropdown option:selected").attr('email')

console.log($("option").attr('email'));
<option value="2" email="[email protected]">John Doe</option>
