alert(document.getElementsByTagName("input").length)
Will get you all the <input> tags.
Maybe you can use some sort of loop to check if the type of each input tag is text.

This one works good enough for me. The only thing is: i have some hidden input tags on the form, Any way to find only the number of visible input tags without going thro all input tags?

Thanks.
