Using jquery find() to select input by class

Question

I have a script which validates each stage of a form and adds a tick or cross to each section if the validation is without errors or not.

Here is my code:

var error = 1;
var hasError = false;
$('.edit_artist').children(':nth-child(' + parseInt(step) + ')').find('input:not(button)').each(function() {
                var $this = $(this);
                var valueLength = jQuery.trim($this.val()).length;
                if(valueLength == '') {
                    hasError = true;    
                }

I dont want the validation to occur on all input fields, so I want to be able to validate inputs by class. Is there a way of finding inputs by class or would I need to go down another route to achieve this?

Thanks

Solution

To find an element based on its class, and while excluding button elements:

$(selector).find('input.className:not("button")');

Or, a more verbose manner:

$(selector).find('input:not("button")').filter(
     function(){
         return $(this).hasClass('className')
     });

• filter().
• find().
