View Full Version : Fill field with day of week field upon user selected date.

Hi folks.

Looking to see if anyone could tell me where I'm going wrong with this script...

I'm trying to have a field automatically filled with the day of the week ("Monday", "Tuesday", "Wednesday" and so on), upon the user selecting a date from the datepicker jQuery. If this isn't clear, I'll clarify further down the page.

Here is the script:

<script type="text/javascript">
var d = $('input[name="item_meta[428]"]').val();
var n = new Date(d).getDay();
if(n == 0)
val v = 'Sunday';
else if(n == 1)
val v = 'Monday';
else if(n == 2)
val v = 'Tuesday';
else if(n == 3)
val v = 'Wednesday';
else if(n == 4)
val v = 'Thursday';
else if(n == 5)
val v = 'Friday';
else if(n == 6)
val v = 'Saturday';

I'm basically trying to say, if the user selected today (15/05/2012) in the field 428 it would fill the field 429 with "Tuesday".

Again, if the user selected 18/05/2012 in the field 428 then it would automatically fill field 429 with "Friday".

It's being done to work in conjunction with a wordpress plugin called Formidable Pro hence the item_meta[428] etc.

Any assistance would be greatly appreciated.

Well, I don't use jQuery, but I don't know why the following won't work:

var d = $('input[name="item_meta[428]"]').value;
var wdays=["Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"];
$('input[name="item_meta[429]"]').value = wdays[(new Date(d)).getDay()];

Instead of using jQuery's val() function, why not use the .value property for the <form> field??? Surely that's what val( ) is doing, under the covers.
