I need help with some javascript form processing. I'm trying to build a dynamic form where the user can add or delete different fields via ajax. Is it possible to use javascript to figure out how many input fields are in the form? Ultimately what I'm trying to achieve is to let the user add or remove fields. everytime the user presses the add button I will use ajax to redraw the form with the new field included. but to do this I need to know how many fields are there before the info is sent to the ajax script.

forms.length

Thanks for the reply. Will that give me a count of the inputs or an array of the inputs?
alert(forms.length) you lazy fat ass!!

That was a little unnecessary.... I'm not at work anymore so I don't have my dev server or production machine to try it out on. I'll try it in the morning.

Please check your pm.

If you want to count the number of input elements on your document, you can use the getElementsByTagName function, which will return to you all input elements in an array.
I don't know if badai's suggestion works.

| Code: |
| //Get all input elements in an array
var v_input = document.getElementsByTagName("input"); //Get the size of the array var i = v_input.length; |
