一直觉得javascript很强大，javascript的框架之多几乎能和java相媲美了：dwr、ext、jquery等。下面我记录的只是一个颜色选择器的使用心得。废话少说，直接看代码：

var ocolorPopup = window.createPopup();
var ecolorPopup=null;
function colordialogmouseout(obj){
obj.style.borderColor="";
obj.bgColor="";
}
function colordialogmouseover(obj){
obj.style.borderColor="#0A66EE";
obj.bgColor="#EEEEEE";
}
function colordialogmousedown(color){
ecolorPopup.value=color;
//document.body.bgColor=color;
ocolorPopup.document.body.blur();
selectColor();
}
function colordialogmore(){
var sColor=dlgHelper.ChooseColorDlg(ecolorPopup.value);
sColor = sColor.toString(16);
if (sColor.length < 6) {
var sTempString = "000000".substring(0,6-sColor.length);
sColor = sTempString.concat(sColor);
}
ecolorPopup.value="#"+sColor.toUpperCase();
//document.body.bgColor="#"+sColor.toUpperCase();

代码也没什么好解释的，看一下就明白了
