jQuery - adding elements into an array

Question

I'm trying to add the ID's, which are the $hexcode values from the html span into an array. How do I do this with jQuery? Eventually, I'm going to need to grab these hexcode values and match them to a color index.

<?php
// display every color in the world
$r = 0;
$g = 0;
$b = 0;
$i = 0;
$step = 16;
for($b = 0; $b < 255; $b+=$step ) {
 for($g = 0; $g < 255; $g+=$step) {
 for($r = 0; $r < 255; $r+=$step) {
 $hexcolor = str_pad(dechex($r), 2, "0", STR_PAD_LEFT).str_pad(dechex($g), 2, "0", STR_PAD_LEFT).str_pad(dechex($b), 2, "0", STR_PAD_LEFT);
 echo '<span class="color_cell" id="'.$hexcolor.'" style="width: 5px; height: 5px; background-color:#'.$hexcolor.'; border: 1px dotted;">&nbsp;</span>'
 if($i%256 == 0) {
 echo "<br />";
 }
 $i++;
 }
 }
}
?> 
<script src="jquery-1.6.2.js"></script>
<script type="text/javascript">
var ids = [];
 $(document).ready(function($) { 
 $(".color_cell").bind('click', function() {
 alert('Test');
 //how do i add the ID (which is the $hexcolor into this array ids[]?
 ids.push($(this).attr('id')); 
 });
});

Thanks in advance!

Answer 1

Try this, at the end of the each loop, ids array will contain all the hexcodes.

var ids = [];
 $(document).ready(function($) {
 var $div = $("<div id='hexCodes'></div>").appendTo(document.body), code;
 $(".color_cell").each(function() {
 code = $(this).attr('id');
 ids.push(code);
 $div.append(code + "<br />");
 });
});

• Richard: Thanks! What is an easy way to check/print my array?
• Jamison Dance: console.log(ids) if you are in Chrome or Firebug on Firefox will log it to the developer console.
• James Hay: var divnew = document.createElement('div'); for(var i = 0; i < ids.length; i++) { divnew.innerHTML += ids[i] + '<br/>'; } $('body').append(divnew)

var ids = [];
 $(document).ready(function($) { 
 $(".color_cell").bind('click', function() {
 alert('Test');
 ids.push(this.id); 
 });
});
