哎，前段开发真心不容易。。。。弄了1个小时，找找了各种素材，终于，字体选色板基本功能弄好了，UI设计技能亟待提升。先看效果：
功能介绍：点击颜色按钮，弹出选色板，选中一个颜色，保存设置，隐藏选色板。。。实现源码如下：

var ColorHex = new Array('00', '33', '66', '99', 'CC', 'FF')
var SpColorHex = new Array('FF0000', '00FF00', '0000FF', 'FFFF00',
'00FFFF', 'FF00FF')
var current = null
function initcolor() {
getArgs();
//chat.js init();
init();
var colorTable = ''
for (i = 0; i < 2; i++) {
for (j = 0; j < 6; j++) {
colorTable = colorTable + '<tr height=15>'
colorTable = colorTable
+ '<td width=15 style="background-color:#000000">'
if (i == 0) {
colorTable = colorTable
+ '<td width=15 style="cursor:pointer;background-color:#'
+ ColorHex[j]
+ ColorHex[j]
+ ColorHex[j]

}
colorTable = colorTable
+ '<td width=15 style="background-color:#000000">'
for (k = 0; k < 3; k++) {
for (l = 0; l < 6; l++) {
colorTable = colorTable
+ '<td width=15 style="cursor:pointer;background-color:#'
+ ColorHex[k + i * 3]
+ ColorHex[l]
+ ColorHex[j]

}
}
}
}
colorTable = '<table border="0" cellspacing="0" cellpadding="0" style="border:1px #000000 solid;border-bottom:none;border-collapse: collapse;width:337px;" bordercolor="000000">'
+ '<tr height=20><td colspan=21 bgcolor=#ffffff style="font:12px tahoma;padding-left:2px;">'
+ '<span style="float:left;color:#999999;">12</span>'

+ '</td></table>'
+ '<table border="1" cellspacing="0" cellpadding="0" style="border-collapse: collapse" bordercolor="000000" style="cursor:pointer;">'
+ colorTable + '</table>';
document.getElementById("colorpane").innerHTML = colorTable;
var current_x = document.getElementById("fontColor").offsetLeft;
var current_y = document.getElementById("fontColor").offsetTop;
//alert(current_x + "-" + current_y)
document.getElementById("colorpane").style.left = current_x + "px";
document.getElementById("colorpane").style.top = current_y + "px";
}
function doclick(obj) {
//document.getElementById("fontColor").value = obj;
document.getElementById("colorpane").style.display = "none";
document.getElementById('msgbox').style.color = obj;
//alert(obj);
//var chatArea = frames["chat"].document
// .getElementsByName('chatArea');
//for ( var i = 0; i < chatArea.length; i++) {
// chatArea[i].style.color = obj;
//}
}
function colorclose() {
document.getElementById("colorpane").style.display = "none";
//alert("ok");
}
function coloropen() {
document.getElementById("colorpane").style.display = "";
}
window.onload = initcolor;
</script>
</body>
</html>
调试的时候，自行修改doclick方法即可。
