Focus Popup Input Field

Question

I am trying to focus the username input when a button it pressed. I have tried autofocus but that doesn't seem to work. Any suggestions?

I don't really want to use javascript for this (haven't yet!) but I know I might have to.

<a class="button" href="#popup1" accesskey="r"><img class="access" src="images/login.png" /></a>


<div id="popup1" class="overlay">
    <div class="popup">
        <div class="popup_header">
            <h2>Log In</h2>
                <a class="close" href="#" accesskey="w">×</a>
        </div>

        <div class="content">
            <section>
                <ul class="input-list cred clearfix">
                <form action="login.php" method="POST">
                    <li>
                        <input type="text" name="username" placeholder="Username">
                    </li>
                    <li>
                        <input type="password" name="password" placeholder="Password">
                    </li>
                    <li>
                        <input type="submit" name="submit" value="Sign In">
                    </li>
                </ul>
            </section>
        </div>      
    </div>

Answer 1

According to your markup for popup I could suggest this method for showing the popup and focusing the input (in this case only the first type text input):

$('a').click(function(e) {
    e.preventDefault();
    var target = $(this).attr('href');
    $(target).show();
    $($('input[type=text]', target).get(0)).focus();
})

Answer 2

autofocus works in IE10+, Chrome, FireFox - please test in other browsers  
but it works only on page load.
<input type="text" name="username" placeholder="Username" autofocus/>
Non supported browsers require JavaScript/Jquery to provide a focus on page
load.
focus on button click always require JavaScript/Jquery.

Answer 3

Try this.

$("#buttonid").click(function(){

//put an id to your username inputbox
$("#username").focus();  

});

Answer 4

You cannot do this without javascript , you can write simple inline javascript.

see the below example:

 a:focus, a:active { color: green; } 

 <form name="myform2"> <input type="text" name="mytextfield2"> <input type="button" name="mybutton" value="Set Focus" OnClick="document.myform2.mytextfield2.focus();"> </form>
