Question

I am trying to create a simple app that writes the values entered in a form on the console:

HTML:

<input type="email" name="email-address" value="" id="email-address" />

<label for="password">Password</label>
<input type="password" name="password" value="" id="password" />

<input type="submit" name="submit" class="btn" value="Login" onclick="login_existing_submit()" id="register-submit" />

Javascript:

function login_existing_submit() {
    console.log(document.getElementById("email-address").value);            
}

Answer 1

You can’t use hyphen in IDs.

<input type="email" name="email-address" value="" id="emailaddress" />

function login_existing_submit() 
{
    console.log(document.getElementById("emailaddress").value);            
}

Working fiddle.
