Date Validation

[adamjblakey]

Hi,

How would i change this to check if the date in the field is at least 2 days in front of today's? Must work with this format yyyy-mm-dd

 
 
if (form.arrivaldate.value == "") {
    alert( "Please make sure your arrival date is at least 2 days in front of today's date" );
    form.arrivaldate.focus();
    return false ;
  }
 
 

Cheers,
Adam

I am assuming "in front of" means "before" today's date - yes?

if (CheckDate(form.arrivaldate.value) == false) {
    alert( "Please make sure your arrival date is at least 2 days in front of today's date" );
    form.arrivaldate.focus();
    return false ;
  }
 

<script language=vbscript>
 
function CheckDate(sDate)
 
    if DateDiff("d", sDate, Now()) < 2 then
        CheckDate = false
    else
        CheckDate = true
    end if
 
end function
 
</script>

var val='2008/02/7';// date input

// get todays date and subtract 2 days
 
var d1=new Date();
d1.setDate(d1.getDate()-2);
 
// or 48 hours: d1.setHours(d1.getHours()-48);
// make a date object from the input- 
// this assumes January is input as 1, not 0:
 
var d2= val.split(/\W+/);
d2=new Date(d2[0]*1,d2[1]-1,d2[2]*1);
 
//see if the input is after the limit:
 
if(d2 > d1) alert('bad date')// throw error message
else alert('good date');

Why use vbscript, when JavaScript can do it?

PS. please use code tags.

Hi,

I am trying:

 var val=(form.arrivaldate.value);// date input 
 
    var d1=new Date();
    d1.setHours(d1.getHours()+48);
 
    // or 48 hours: d1.setHours(d1.getHours()-48);
    // make a date object from the input-
    // this assumes January is input as 1, not 0:
    var d2= val.split(/\W+/);
 
    d2=new Date(d2[0]*1,d2[1]-1,d2[2]*1);
 
    //see if the input is after the limit:
    if(d2 > d1) {
    alert( "Please a date at least 2 days after today's date" );
    form.arrivaldate.focus();
    return false ;
    }

But this does not cover the 2 days after today's date. What this does is goes 2 days ahead and then does not allow any days after this. I need it to work for just the 2 days after today's date.

Any Ideas?

Cheers,
Adam

d1 is two days after today's date. You need to change the if statement comparison around:

//see if the input is after the limit:
    if(d2 <= d1) {

Thanks for that, it works fine.

You're welcome. Glad it helped.
