jquery get all input from specific form

Is there any ways to populate all of the input from certain form? let say, some thing like this:

<form id="unique00">
  <input type="text" name="whatever" id="whatever" value="whatever" />
  <div>
    <input type="checkbox" name="whatever" id="whatever" value="whatever" />
  </div>
  <table><tr><td>
    <input type="hidden" name="whatever" id="whatever" value="whatever" />
    <input type="submit" value="qweqsac" />
  </td></tr></table>
</form>
<form id="unique01">
  <div>
    <input type="text" name="whatever" id="whatever" value="whatever" />
    <input type="checkbox" name="whatever" id="whatever" value="whatever" />
  </div>
  <table><tr><td>
    <input type="hidden" name="whatever" id="whatever" value="whatever" />
  </td></tr></table>
  <select>blah...</select>
  <input type="submit" value="qweqsac" />
</form>
etc forms... forms...

*note: each form might have a different amount of input and type and also different html structure

so is there any way to populate the input from certain form id? eg if i click submit button from certain form id, then jquery will populate for me all of the input within those form id. currently what i'm doing is like this:

$("form").submit(function(){ return validateForm($(this)) });
function validateForm(form){
var retVal = true;
var re;
$.each(form.serializeArray(), function(i, field) {
  var input = $('input[name='+field.name+']');
  field.value = $.trim(field.value);
  switch(field.name){
    case "name" :
        and another cases...
      }
    })
 }

that was work, but in that case, i only get the field.name and field.value, and actually what i want is, i want a jquery object for each input element, so i can access their css, id, name, and even animate those input element

is there any way for this?

please let me know and thank you in advance! AnD

$(document).on("submit","form",function(e){
        //e.preventDefault();
        $form = $(this);
        $i = 0;
        $("form input[required],form select[required]").each(function(){
            if ($(this).val().trim() == ''){
                $(this).css('border-color', 'red');
                $i++;
            }else{
                $(this).css('border-color', '');    
            }               
        })
        if($i != 0) e.preventDefault();
    });
    $(document).on("change","input[required]",function(e){
        if ($(this).val().trim() == '')
            $(this).css('border-color', 'red');
        else
            $(this).css('border-color', '');    
    });
    $(document).on("change","select[required]",function(e){
        if ($(this).val().trim() == '')
            $(this).css('border-color', 'red');
        else
            $(this).css('border-color', '');
    });

Use HTML Form "elements" attribute:

$.each($("form").elements, function(){ 
    console.log($(this));
    });

Now it's not necessary to provide such names as "input, textarea, select ..." etc.

The below code helps to get the details of elements from the specific form with the form id,

$('#formId input, #formId select').each(
    function(index){  
        var input = $(this);
        alert('Type: ' + input.attr('type') + 'Name: ' + input.attr('name') + 'Value: ' + input.val());
    }
);

The below code helps to get the details of elements from all the forms which are place in the loading page,

$('form input, form select').each(
    function(index){  
        var input = $(this);
        alert('Type: ' + input.attr('type') + 'Name: ' + input.attr('name') + 'Value: ' + input.val());
    }
);

The below code helps to get the details of elements which are place in the loading page even when the element is not place inside the tag,

$('input, select').each(
    function(index){  
        var input = $(this);
        alert('Type: ' + input.attr('type') + 'Name: ' + input.attr('name') + 'Value: ' + input.val());
    }
);

NOTE: We add the more element tag name what we need in the object list like as below,

Example: to get name of attribute "textarea",

$('input, select, textarea').each(
    function(index){  
        var input = $(this);
        alert('Type: ' + input.attr('type') + 'Name: ' + input.attr('name') + 'Value: ' + input.val());
    }
);

To iterate through all the inputs in a form you can do this:

$("form#formID :input").each(function(){
 var input = $(this); // This is the jquery object of the input, do what you will
});

This uses the jquery :input selector to get ALL types of inputs, if you just want text you can do :

$("form#formID input[type=text]")//...

etc.
