What\'s the object type returned by Datepicker? Supposing I have the following:
$(\"#txtbox\").datepicker({
onClose: function(date){
//something
A Date object is returned by the datePicker.
Your method for comparing dates is valid - from W3schools:
var myDate=new Date();
myDate.setFullYear(2010,0,14);
var today = new Date();
if (myDate>today)
{
alert("Today is before 14th January 2010");
}
Are you getting a value in oDate from this line?
oDate = $("#oDP").datepicker("getDate");
Your comparison method seems valid - so I'm wondering if datePicker is successfully pulling a value from #oDP?
Edit - oDate confirmed to contain a valid date. This may be a very silly question, but have you confirmed that date contains a valid date? I'm wondering if there may be some issue with naming it the same as the keyword Date (Javascript keywords and reserved words). Perhaps try renaming it to tDate or the like in your function to be doubly-clear this isn't causing your problems.
