Hi,

Have a form that has a date period defined in a select drop down, at present its Fortnight, Month and 6 Month.

I have this code:

jQuery(function(){
   var dfdate=function(){return calculateDate()}();
    jQuery("#Enter_date").datepicker({
        defaultDate: dfdate,
        dateFormat: 'dd/mm/yy',
        changeMonth: true,
        beforeShowDay: jQuery.datepicker.noWeekends,
        minDate: 0
    });
})

function calculateDate(){
    var freq = jQuery('#frequency option:selected').attr('label');
    var twovalue;
    var retString;
    if(freq.indexOf(' ') >= 0){
        twovalue=  freq.split(' ');
    }
    if (freq.indexOf(' ') >= 0){
        twovalue=  freq.split(' ');
        var freqNo = twovalue[0];
        var freqPeriod = twovalue[1].charAt(0).toLowerCase();
        retString = "+"+freqNo+freqPeriod
    }else if(freq.toLowerCase() == "fortnight"){
        retString = "+2w";
    }else{
        retString = "+1"+ freq.charAt(0).toLowerCase();
    }
    return retString;
}

Open in new window


What I would like to happen is that when the selected option changes that the period defaultDate be  defined in as can be returned by the function.

How can this be done?
