Get the date from database to html date textbox

hi all

i have a table name table1 

id  name mname lname date

to insert date in this table i have used all html controls

(like  <input type="text" id="txtname" required="required" /> and 

<input type="date" id="txtdob" required="required"/>).and for this purpose i have used ajax jquery to insert data in database .

problem is that when i want to update the data then i want the stored data should be filled in textboxes ,i have fill the id,name,mname,lname but getting the problem in date .

I have read data like that in javascript :dj("#txtname").val(data.d[0].name);

but this is not working for date

thank you...........
