You can achieve this with something like the following. You need an id attribute for you input. Then on blur event you will change the div background color with the input value if it is valid.
Also, you have to include jQuery in html <head>.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script>
JSFIDDLE
HTML:
<input type="text" name="bgcolor" id="bgcolor" maxlength="6" placeholder="Hex representation of the color">
JQuery:
$(document).ready(function() {
$('#bgcolor').on('change', function() {
var color = $(this).val();
var isOk = /(^#[0-9A-F]{6}$)|(^#[0-9A-F]{3}$)/i.test('#'+color)
if (isOk) { //If input is a valid representation of a color
$('#your_div_id').css('background-color', '#'+color);
}
});
});
isOk regex from here.
Or using type="color":
HTML:
<input type="color" name="bgcolor" id="bgcolor" value="">
JQuery:
$(document).ready(function() {
$('#bgcolor').on('change', function() {
var color = $(this).val();
$('#your_div_id').css('background-color', color);
});
});
UPDATE:
Move the following inside $(document).ready(function () { like this:
$(document).ready(function () {
$('span.pq').each(function () {
var quote = $(this).clone();
quote.removeClass('pq');
quote.addClass('pullquote');
$(this).before(quote);
}); //end each
$('#note').draggable();
$('#bgcolor1').on('change', function () {
var color = $(this).val();
$('#id1').css('background-color', color);
});
$('#bgcolor2').on('change', function () {
var color = $(this).val();
var isOk = /(^#[0-9A-F]{6}$)|(^#[0-9A-F]{3}$)/i.test('#' + color)
if (isOk) { //If input is a valid representation of a color
$('#id1').css('background-color', '#' + color);
}
});
});
