var thei = $(this).height(); //控件本身的高
var tleft = $(this).offset().left; //控件的定位点宽
$("#colorpanel").css({
top: ttop + thei + 5,
left: tleft
})
$("#colorpanel").show();
$("#CT tr td").unbind("click").mouseover(function () {
var aaa = $(this).css("background-color");
$("#DisColor").css("background-color", aaa);
$("#HexColor").val(aaa);
}).click(function () {
var aaa = $(this).css("background-color");
$('#' + txtobj).val(aaa).css("color", aaa);
$("#colorpanel").hide();
})
$("#_cclose").click(function () { $("#colorpanel").hide(); }).css({ "font-size": "12px", "padding-left": "20px" })
})
}
jQuery.extend({
showcolor: function (btnid, txtid) { showColorPanel(btnid, txtid); }
})
完成， 效果如下图所示
