寻求调色板代码！

ling_l 2003-10-16 09:23:25

希望在输入框中输入颜色，可以通过双击此输入框或点击特定的按钮显示调色板，选择颜色后直接显示在输入框中
谁有这样的代码，万分感谢！

随便找个网页编辑器，取里面的COLOR编辑器就可以了

在你的页面里调用下面的函数可以打开对话框
function foreColor()
{
if (! validateMode()) return;
var arr = showModalDialog("selcolor.asp", "", "dialogWidth:18.5em; dialogHeight:17.5em; status:0");
//if (arr != null) format('forecolor', arr);
//else HtmlEdit.focus();
}
