Hey everyone!

I'm not that good with javascript so I was hoping to get some help from you experts.

I downloaded some code for a color picker and it doesn't have the full spectrum of colors. So my question is: can anyone figure out how to add more colors to this code?

Javascript:



<script language="Javascript">
var perline = 9;
var divSet = false;
var curId;
var colorLevels = Array('0', '3', '6', '9', 'C', 'F');
var colorArray = Array();
var ie = false;
var nocolor = 'none';
if (document.all) { ie = true; nocolor = ''; }
function getObj(id) {
if (ie) { return document.all[id]; }
else { return document.getElementById(id); }
}

function addColor(r, g, b) {
var red = colorLevels[r];
var green = colorLevels[g];
var blue = colorLevels[b];
addColorValue(red, green, blue);
}

function addColorValue(r, g, b) {

colorArray[colorArray.length] = '#' + r + r + g + g + b + b;
}

function setColor(color) {
var link = getObj(curId);
var field = getObj(curId + 'field');
var picker = getObj('colorpicker');
field.value = color;
if (color == '') {
link.style.background = nocolor;
link.style.color = nocolor;
color = nocolor;
} else {
link.style.background = color;
link.style.color = color;
}
picker.style.display = 'none';
eval(getObj(curId + 'field').title);
}

function setDiv() {
if (!document.createElement) { return; }
var elemDiv = document.createElement('div');
if (typeof(elemDiv.innerHTML) != 'string') { return; }
genColors();
elemDiv.id = 'colorpicker';
elemDiv.style.position = 'absolute';
elemDiv.style.display = 'none';
elemDiv.style.border = '#000000 1px solid';
elemDiv.style.background = '#FFFFFF';
elemDiv.innerHTML = '<span style="font-family:Verdana; font-size:11px;">'
+ ''
+ getColorTable()
+ ''
+ '</center></span>';

document.body.appendChild(elemDiv);
divSet = true;
}

function pickColor(id) {
if (!divSet) { setDiv(); }
var picker = getObj('colorpicker');
if (id == curId && picker.style.display == 'block') {
picker.style.display = 'none';
return;
}
curId = id;
var thelink = getObj(id);

picker.style.top = getAbsoluteOffsetTop(thelink) + 20;
picker.style.left = getAbsoluteOffsetLeft(thelink);
picker.style.display = 'block';
}

function genColors() {
addColorValue('0','0','0');
addColorValue('3','3','3');
addColorValue('6','6','6');
addColorValue('8','8','8');
addColorValue('9','9','9');
addColorValue('A','A','A');
addColorValue('C','C','C');
addColorValue('E','E','E');
addColorValue('F','F','F');

for (a = 1; a < colorLevels.length; a++)
addColor(0,0,a);
for (a = 1; a < colorLevels.length - 1; a++)
addColor(a,a,5);

for (a = 1; a < colorLevels.length; a++)
addColor(0,a,0);
for (a = 1; a < colorLevels.length - 1; a++)
addColor(a,5,a);

for (a = 1; a < colorLevels.length; a++)
addColor(a,0,0);
for (a = 1; a < colorLevels.length - 1; a++)
addColor(5,a,a);


for (a = 1; a < colorLevels.length; a++)
addColor(a,a,0);
for (a = 1; a < colorLevels.length - 1; a++)
addColor(5,5,a);

for (a = 1; a < colorLevels.length; a++)
addColor(0,a,a);
for (a = 1; a < colorLevels.length - 1; a++)
addColor(a,5,5);

for (a = 1; a < colorLevels.length; a++)
addColor(a,0,a);
for (a = 1; a < colorLevels.length - 1; a++)
addColor(5,a,5);

return colorArray;
}
function getColorTable() {
var colors = colorArray;
var tableCode = '';
tableCode += '<table border="0" cellspacing="1" cellpadding="1">';
for (i = 0; i < colors.length; i++) {
if (i % perline == 0) { tableCode += '<tr>'; }
tableCode += '<td bgcolor="#000000"><a style="outline: 1px solid #000000; color: '
+ colors[i] + '; background: ' + colors[i] + ';font-size: 10px;" title="'
+ colors[i] + '" href="javascript:setColor(\'' + colors[i] + '\');">&nbsp;&nbsp;&nbsp;</a></td>';
if (i % perline == perline - 1) { tableCode += '</tr>'; }
}
if (i % perline != 0) { tableCode += '</tr>'; }
tableCode += '</table>';
return tableCode;
}
function relateColor(id, color) {
var link = getObj(id);
if (color == '') {
link.style.background = nocolor;
link.style.color = nocolor;
color = nocolor;
} else {
link.style.background = color;
link.style.color = color;
}
eval(getObj(id + 'field').title);
}
function getAbsoluteOffsetTop(obj) {
var top = obj.offsetTop;
var parent = obj.offsetParent;
while (parent != document.body) {
top += parent.offsetTop;
parent = parent.offsetParent;
}
return top;
}

function getAbsoluteOffsetLeft(obj) {
var left = obj.offsetLeft;
var parent = obj.offsetParent;
while (parent != document.body) {
left += parent.offsetLeft;
parent = parent.offsetParent;
}
return left;
}


</script>


HTML:



<a href="javascript:pickColor('pick1');" id="pick1" style="border: 1px solid #000000; font-family:Verdana; font-size:10px;text-decoration: none;">&nbsp;</a>
<input id="pickfield" size="15" READONLY name="Colors1">
<script language="javascript">relateColor('pick1', getObj('pick1').value);</script>


Thanks for your help!
