Javascript Change DIV background color onclick

I'm trying to change the colour of a div after a form has been submitted. The div on the new page should be in the colour selected.

JS

 function change(col) {   
     col.style.backgroundColor = '<?php echo $colour ?>';    
 }

HTML

<form action="" method="post">
    <input type='search' name='keywords' value='' style="width:100%;">
<a href='#col'>
<input type=submit  value='Submit' name='doSearch' style="visibility: hidden;" onclick="change(this.href)" />
 </a>

</form>
<div id="col" onclick="location.href='index2.php';">
    <br/>
    <?php echo $message ?>
</div>

<? $message="dd"; ?>
<script>
function change(col) {
document.getElementById('col').style.backgroundColor=col;
}
 </script>

<form action="" method="post">
<input type='search' name='keywords' value='' style="width:100%;">

<a href='#col'>
<input type=submit  value='Submit' name='doSearch' style="visibility: hidden;" onclick="enter(this.href)" />
 </a>
 </form>


<div style="width:50px; height:50px;" id="col" onclick="location.href='index2.php';" >

 <br/>
<?php echo $message ?>

</div>
<? if(isset($_POST['keywords'])){ ?>
<script>
 change('<?=$_POST['keywords']?>');
</script>
<? } ?>

test it, it works by inserting the color on the keywords input

have a look here: http://jsfiddle.net/TeFYV/

code

var colors = ["red", "blue", "yellow", "green", "orange", "black", "cyan", "magenta"]

function changeColor() {
    //you can as well pass col reference as you do in your code
    var col = document.getElementById("changecolor");
    col.style.backgroundColor = colors[Math.floor((Math.random()*8)+1)];
}

Adapt to your needs, hope it helps

Easiest way would be to pass the color as a parameter between the two pages and then use jQuery on the second page to set the color with the one you got from that parameter.

You could do this easily with jQuery:

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

  $(this).css("background-color","yellow");

  });
