$('input:text[id^=mytextbox]').each(function() {
    if ($(this).attr('val') == "")
        alert("Empty box - " + $(this).attr('id'));
});

Will make a alert box for all empty text box you have that have a id that starts with "mytextbox"

Hi,

I understand your answer and got a little help from it.

I have 6 textboxes and the following line gives me the answer "Size: 6".

[code
alert('Size: ' + $('input:text[id*=txtReportsPersonCustomerPrice]').size());
[/code]

How do you add to this line to select only those textboxes that has no text put into them?

If i have entered text into say 2 boxes then the answer should be 2.

Thanks!

For the size on the textbox with out value content

alert('Size: ' + $('input:text[id*=txtReportsPersonCustomerPrice][value=]').size());

For the size of the textbox with some thing in the value

alert('Size: ' + $('input:text[id*=txtReportsPersonCustomerPrice]:not([value=])').size());
