jQuery help

Hi All,

Please help me on the below tasks using jQuery.

1) How to disable the future dates for the datepicker?
2) How to allow the time for the datepicker?
3) Textbox with slider : By default the value should be zero in the textbox. Textbox should allow only numeric values. On typing the value in the textbox, the slider should be displayed with the respective value & vice versa (on dragging and selecting the value in the slider, the respective value should be shown in the textbox).

Let me know if you have any queries.

Thanks In Advance,
Kumar.
