In jQuery DatePicker there is开发者_如何学Go one annoying thing, if you using it as a calendar and depend on selected date. While navigating from month to month it keep selected day activated for all months. I know that this issue exist for more than 6 months and I have reported it to jQuery Team.However I would like to know is there any workarounds or how to disable this behaviour?
Calendar example can be found here
here's a workaround I figured out.
$(function() {
$("#datepicker").datepicker({
onChangeMonthYear: function(year, month, inst) {
var bMonth = (new Date(this.value)).getMonth() != month - 1;
var bYear = (new Date(this.value)).getFullYear() != year;
if (bMonth || bYear) {
setTimeout(function() {
$('.ui-state-active').removeClass('ui-state-active');
}, 5);
}
}
});
});
crazy demo
Include this script after you've included jQuery UI. You can include it inline, or put it in its own file. edit: This hack fixes your issue for version 1.8.5 of jQuery UI. I have tested a number of usage cases in FF 3.6.10 and IE 8. It is entirely possible that this hack does not work under all possible circumstances. If I notice any, I'll probably try to fix them, but for now, it is provided as is. I've thrown together a demo. Shows it's working with jQuery 1.8.4, too. Just to be clear... my solution is not a quick and dirty workaround, it's an actual fix of the bug in the datepicker code. It's so long, because it overwrites an original method (and thus contains the original code in its entirety). The fix itself is a change in just one line. But I've provided the fix as a script that can just be included without having to edit the original code at all, for convenience.

Here's the ticket:
http://dev.jqueryui.com/ticket/5984
It includes the fix and a workaround for the compressed version.
I think you can modify your copy of jQuery UI safely. The issue is already solved so it should show up in next stable release.
