    its ok.. no problem....... but the thing is i need it as a search box.. (i.e... the text box content should be of "Enter the search criteria here..." and this should be italic style. when user click the textbox the content should get clear and normal texts should be typed (i seen this in many sites including MICROSOFT))

    hi,

     if you have more than one calendar , like calerdar1, calendar2, calendar3, and you want to make them all hidden on one action on esc key, you must write modify the previous code like this :

     

    if(the_key == 27) {

    document.getElementById("Calendar1").style.visibility="hidden";

    document.getElementById("Calendar2").style.visibility="hidden";

    document.getElementById("Calendar3").style.visibility="hidden";

    bye

    thanks  friend.but the thing is user may select anyone of the calendar. when user press ESC key, the problem arise... (all the 3 calendar will wont be visible all times. anyone only. User may select any calendar by clicking a button, select value and press ESC key).

    hi karan.

    if the other calendars are "hidden" ; they can't be more hidden when you press esc, so if you leave my last code, i think it will work .

     

    maheshkrp : at work , my boss don't like ajax embeddings for our applications .. because they are made for thousands and thousands users ...  
    So for internal apps, we can use ajax or other stuff, for external apps, only classicak use of client javascript allowed.
