Datepicker altFormat issue

in Using jQuery UI • 5 years ago

The documentation seems to indicate, altFormat:"MM dd, yy" would return April 07, 2017 for today, but it actually returns "04/07/2017", what's going on? Did I misread its doc?

Thanks.

Did you also set altField?

Hard to debug code we can't see. If you still have a problem, make a jsFiddle showing the problem.

Why would we need altField for this?

Here's my complete code for this guy:

(function() {

var d = new Date();

var maxD = new Date(d.setDate(d.getDate()));

$('.givemedate').datepicker({changeMonth: true,changeYear: true,yearRange: "-31:+0",maxDate:maxD,altFormat:"MM dd, yy"});

})();

Thanks.

altFormat does nothing unless you also give altField.

When you set altField to some selector, Datepicker updates a second input as well. altField gives the format of the second field.

https://api.jqueryui.com/datepicker/#option-altField

You might typically hide the additional field, if your intention is to provide an alternative format for upload in a form.

<input type="text" id="DateField1" name="DateField1" class="givemedate">
<input type="hidden" id="otherField" name="otherField">
(function() {
var d = new Date();
var maxD = new Date(d.setDate(d.getDate()));
$('.givemedate').datepicker({
changeMonth: true,
changeYear: true,
yearRange: "-31:+0",
maxDate: maxD,
altField: "#otherField"
altFormat:"MM dd, yy"});
})();

Some of the wording in the documentation might be confusing:

This allows one date format to be shown to the user for selection purposes, while a different format is actually sent behind the scenes.

It doesn't do this by magic. ("magic" would be needed to show one format to the user, whist sending a different one to the server...) It does it by using two different fields.

-----

Let's back up... what is it you are trying to do?

This is not just convoluted but also unable to solve the problem of multiple elements with datepicker using class instead of element id. Thanks tho.

Tho one can use multiple IDs for each element, it won't work for users, a user would expect select a date for the field and the selected date would show up in the same field, otherwise, the user would utter WTF.

This is not a solution.

For multiple datepickers, you need something like jQuery UI Datepicker - onSelect added text 2

It would help considerably if you would state what your problem is, and then we can offer a solution.

So far, you guessed at a wrong solution, and now are complaining that it doesn't solve your problem. Well, that's because the solution you chose isn't meant to solve your problem. It solves a different one.

Now, if we knew what your problem IS, we could help you.

Apparently, it has something to do with "the problem of multiple elements with datepicker using class instead of element ID".

You've told us there's some problem. Now, just what is that problem?

Can you make a jsFiddle that demonstrates it?

If you just want to change the format accepted and displayed, that's what dateFormat is for. Not altFormat.
