jquery datepicker range validation #2

[pietpiraat]

Hello all,

i posted this a while ago and the thread closed, this was my original question:

<script type="text/javascript">
$(function() {
    $('#inlineDatepicker').datepick({
    rangeSelect: true,
    monthsToShow: 3,
    minDate: '+7d',
    rangeSeparator: '|',
    altField: '#resdate',
    altFormat: 'dd-mm-yyyy',
    pickerClass: 'locgrid',
    onDate: nationalDays
    }
    );
});
var natDays = [[12, 18, 2010], [12, 19, 2010]]; 

function nationalDays(date, inMonth) { 
    if (inMonth) { 
        for (i = 0; i < natDays.length; i++) { 
            if (date.getMonth() + 1 == natDays[i][0] && 
                    date.getDate() == natDays[i][1] &&
                        date.getFullYear() == natDays[i][2]
                    ) { 
                return {dateClass: natDays[i][3] + '_day', selectable: false}; 
            } 
        } 
    } 
    return {}; 
}

now what i'm trying to accomplish is, when a user clicks a start- and enddate and there is a natDays variable in between to throw an error message.

any ideas?

This is what airshow answered, thanks for that btw:

Piet,

I think I have it.

In the datepick settings, change onDate: nationalDays to onSelect: nationalDays .

Then nationalDays should be as follows:

function nationalDays(dates) {
    var natDate;
    var includesNatDate = false;
    for (i=0; i<natDays.length; i++) {
        d = $.datepick.newDate(natDays[i][2], natDays[i][0], natDays[i][1]);
        if(d.getTime() >= dates[0].getTime() && d.getTime() <= dates[1].getTime()) {
            includesNatDate = true;
            break;
        }
    }
    $("#message").html('includesNatDate : ' + includesNatDate);
}

In the last line, I just display a true|false message but you will do whatever is necessary in your application. There's no point returning true|false from nationalDays because it is a callBack function and you don't have access to the returned value.

Hope this helps.
