I dont think this option is exposed va the api.
I belive that the easiest way is to change the stylesheet.
Change the ui-datepicker-year
class to display: none
Another option would be to edit the source so it isnt rendered at all,
to do that you can remove this part of the code:
// year selection
if (secondary || !changeYear)
html += '<span class="ui-datepicker-year">' + drawYear + '</span>';
else {
// determine range of years to display
var years = this._get(inst, 'yearRange').split(':');
var thisYear = new Date().getFullYear();
var determineYear = function(value) {
var year = (value.match(/c[+-].*/) ? drawYear + parseInt(value.substring(1), 10) :
(value.match(/[+-].*/) ? thisYear + parseInt(value, 10) :
parseInt(value, 10)));
return (isNaN(year) ? thisYear : year);
};
var year = determineYear(years[0]);
var endYear = Math.max(year, determineYear(years[1] || ''));
year = (minDate ? Math.max(year, minDate.getFullYear()) : year);
endYear = (maxDate ? Math.min(endYear, maxDate.getFullYear()) : endYear);
html += '<select class="ui-datepicker-year" ' +
'onchange="DP_jQuery_' + dpuuid + '.datepicker._selectMonthYear(\'#' + inst.id + '\', this, \'Y\');" ' +
'onclick="DP_jQuery_' + dpuuid + '.datepicker._clickMonthYear(\'#' + inst.id + '\');"' +
'>';
for (; year <= endYear; year++) {
html += '<option value="' + year + '"' +
(year == drawYear ? ' selected="selected"' : '') +
'>' + year + '</option>';
}
html += '</select>';
}
I haven't tried removing the code but it should work.
I did try hiding it using css and that does work (in firefox anyway :) )
