采用Javascript实现，用鼠标点击相应颜色，动态改变网页背景颜色
这是截图
相应的Javascript源代码为：
hex[0] = "FF"
hex[1] = "CC"
hex[2] = "99"
hex[3] = "66"
hex[4] = "33"
hex[5] = "00"
function display(triplet) {
document.bgColor = '#' + triplet
}
function drawCell(red, green, blue) {
document.write('<TD BGCOLOR="#' + red + green + blue + '">')
document.write('<A HREF="javascript:display(\'' + (red + green + blue) + '\')">')
document.write('<IMG SRC="place.gif" BORDER=0 HEIGHT=12 WIDTH=12>')
document.write('</A>')
document.write('</TD>')
}
function drawRow(red, blue) {
document.write('<TR>')
for (var i = 0; i < 6; ++i) {
drawCell(red, hex[i], blue)
}
document.write('</TR>')
}
function drawTable(blue) {
document.write('<TABLE CELLPADDING=0 CELLSPACING=0 BORDER=0>')
for (var i = 0; i < 6; ++i) {
drawRow(hex[i], blue)
}
document.write('</TABLE>')
}
function drawCube() {
document.write('<TABLE CELLPADDING=5 CELLSPACING=0 BORDER=1><TR>')
for (var i = 0; i < 6; ++i) {
document.write('<TD BGCOLOR="#FFFFFF">')
drawTable(hex[i])
document.write('</TD>')
}
document.write('</TR></TABLE>')
}
drawCube()
