All formfields in javascript?

[Igor0208]

Hello everyone.

First I want to say: I'm from the Netherlands, and my Engelish is not that good, so sorry for that

My problem:

I have a form. With a database I get some variables and with that variables I make some input fields. But, the number of fields can be different, and they have different names.

I want to submit the form with ajax, but before I can do that, I have to know what input fields I have. So, my question is: how can I figure out which input fields I have, and, how can I put them as arguments in a js-function?

I hope you people can help me...

Greetings,
Igor0208

Is it just one form? If so, loop through the childNodes of document.forms[0].

<script>
function countFields() {
	var fieldsCounter = 0;
	for (var k = 0; k < document.forms[0].childNodes.length; k++) {
		var tag;
		if (typeof (tag = document.forms[0].childNodes[k]).tagName != "undefined") {
			if (tag.tagName.toLowerCase() == "input" && tag.type.toLowerCase() != "submit") fieldsCounter++;
		}
	}
	alert(fieldsCounter);
}
</script>

<form action="javascript:countFields();">
	<input type="text" id="field1" />
	<input type="text" id="field1" />
	<input type="submit" value="asd" />
</form>

why did you use childNodes?

You can use elements

document.forms[0].elements.length
document.forms[0].elements[0].value
