Question

          $('input.metaTitle').filter(function() {
            $(this).val('ya');
          });

The above code finds all inputs with the metaTitle class.

I can’t seem to update it to only select empty fields. I’ve tried things like:

          if(!$('input.metaTitle').val()).filter(function() {
            $(this).val('ya');
          });

Can someone advise how to limit this to only empty inputs.

thx

Use…

$('input.metaTitle').filter(function() {
   return $(this).val().length;
});

jsFiddle.

…to select them.

I think using $('input.metaTitle[value=""]') may be flaky as document.querySelectorAll() checks the initial value attribute I think. It also won’t work if the element doesn’t have a value attribute.
