Question

I am using date picker of extjs 4.
I need to enable only three dates and
to disable everything else. How
do I do it ?

Answer 1

I would suggest starting with the API docs for Ext.menu.DatePicker, which I assume that you are doing.

However, if there are only a total of three static dates ever available, why not use something besides a date picker for the task?

If you are picking from a set of dates that could be stored in an array, I’d suggest reading this Sencha forum post about using DateField along with an array that disables all dates other than those specified in an array as follows:

dateArray = ["06/17/2007", "06/01/2007", "05/17/2007", "05/01/2007"];

dateField = new Ext.form.DateField({
    format: "m/d/Y",
    disabledDates: ["^(?!" + dateArray.join("|") + ").*$"],
    disabledDatesText: "Date not available."
});
