Placeholders with divs, not inputs/textareas

I have working on this problem for a couple weeks off and on. What I am trying to do is have placeholders to show users where they can type. When they do type, I want the placeholder to disappear, but reappear again when the div is empty.

Every thing I have found has to do with cross-browser placeholder support for inputs and textareas, and trying to apply the code for them to my issue results in failure.

I am using h1s for titles and standard divs for descriptions.

My code looks like this:

HTML

<div class="page-desc" contenteditable="true" data-placeholder="Write your description here."></div>

jQuery

var placeholder = '<span class="placeholder">Write your title here</span>';
$(this).html(placeholder);

I have more jQuery code, but it sucks. I am currently using keyup to hide the placeholder, and that's obviously not working. Can someone help me out?

I am totally open to using vanilla JavaScript as well.

Why not use the Blur and Focus event handlers from jQuery and check the Text value of the Div?

Code for quick look:

$('[contenteditable="true"]').blur(function() {
    var text = $.trim($(this).text());
    var ph = $('<span/>',{ 'class':"placeholder"})
        .text($(this).data('placeholder')||'');
    if (text == '') {
        $(this).html(ph);
    }
}).focus(function() {
    if ($(this).children('.placeholder').length > 0) {
        $(this).html('<span>&nbsp;</span>');
    }
});

You can have something like this:

$('#xdiv').html($('#xdiv').data('placeholder'));

$('#xdiv').keydown(function() {
    if ($(this).html() == $(this).data('placeholder')) {
        $('#xdiv').html('');
    }
})

$('#xdiv').keyup(function() {
    if ($(this).html() == '') {
        $('#xdiv').html($('#xdiv').data('placeholder'));
    }
})

Initially it sets DIV's HTML to placeholder text. Then when user begins to type (on keydown) it checks if DIV still has the placeholder text and if so - removes it. And since user can delete all the data - it checks (on keyup) if DIV is empty, and if so - restores placeholder's text.

Why can't you use the placeholder attribute of the input element. It seems to do exactly what you want and it's very well supported (http://caniuse.com/input-placeholder). Sorry if I have missed something.

Javascript solution (not as pretty, but more cross-browser):

$("#in").keyup(function(){
    if(!$(this).html()){
        $(this).html($(this).attr('data-placeholder'));
        $(this).attr('showing-placeholder',true);
    }
});
$("#in").keydown(function(){
    if($(this).attr('showing-placeholder')){
        $(this).html('');
        $(this).attr('showing-placeholder','');
    }
});

Working Example: JSFiddle;

there's a way to do it in css (modern browser only)

        .pageDesc:empty:after {content : "Write your description here.";}
