JQuery Validation: Validating hidden fields

jqueryjquery-validate

Since the release of the JQuery Validation Plugin version 1.9.0, hidden fields have been automatically omitted from validation checks [source].

According to the release notes, the way to get around this is by setting ignore: [] in the validation function.

Using version 1.10.0, I am unable to get this to work for input fields that are hidden using display: none or visibility: hidden.

My validation is done using classes (eg, class="required") and the validation function is fairly basic:

JQuery

$("form").validate({
    ignore: [],  
    errorPlacement: function(error, element) {
        error.appendTo( $('#error-message') )
    },
    invalidHandler: function() {
        //do something 
    },
    submitHandler: function() {
        //do something else
    }
});

Working example: http://jsfiddle.net/fbCVY/

Can anyone point out where I am going wrong?

I think you need to provide both a unique id and a unique name attribute for each of the input tags so that the validation plugin can find the fields and can tell them apart. The two "hidden" fields are not failing validation because the first field on the form passes, and that result is being used for the other two fields.

Javascript – n “exists” function for jQuery

In JavaScript, everything is 'truthy' or 'falsy', and for numbers 0 means false, everything else true. So you could write:

if ($(selector).length)

You don't need that >0 part.

Javascript – Add table row in jQuery

The approach you suggest is not guaranteed to give you the result you're looking for - what if you had a tbody for example:

<table id="myTable">
  <tbody>
    <tr>...</tr>
    <tr>...</tr>
  </tbody>
</table>

You would end up with the following:

<table id="myTable">
  <tbody>
    <tr>...</tr>
    <tr>...</tr>
  </tbody>
  <tr>...</tr>
</table>

I would therefore recommend this approach instead:

$('#myTable tr:last').after('<tr>...</tr><tr>...</tr>');

You can include anything within the after() method as long as it's valid HTML, including multiple rows as per the example above.

Update: Revisiting this answer following recent activity with this question. eyelidlessness makes a good comment that there will always be a tbody in the DOM; this is true, but only if there is at least one row. If you have no rows, there will be no tbody unless you have specified one yourself.

DaRKoN_ suggests appending to the tbody rather than adding content after the last tr. This gets around the issue of having no rows, but still isn't bulletproof as you could theoretically have multiple tbody elements and the row would get added to each of them.

Weighing everything up, I'm not sure there is a single one-line solution that accounts for every single possible scenario. You will need to make sure the jQuery code tallies with your markup.

I think the safest solution is probably to ensure your table always includes at least one tbody in your markup, even if it has no rows. On this basis, you can use the following which will work however many rows you have (and also account for multiple tbody elements):

$('#myTable > tbody:last-child').append('<tr>...</tr><tr>...</tr>');
