JS Validation does not work with javascript code in On Load

Dear friends , I have developed a form (chronoforms V4) with some fields in containers <div rel="..."> code field < / div> that are dynamically displayed or hidden by selecting the options in a radio box . The function is obtained by JavaScript code that is loaded in "On Load" with a JS action . I could verify that it does not work the JS Validation of the form, if I delete from the JS form action that manages <div> everything works fine (obviously not the dynamic fields ).
How can resolve this problem? Thanks for the help that you give me. The JavaScript code loaded into On Load is as follows.

var containerTag = 'DIV';

var compatible = (
	document.getElementById && document.getElementsByTagName && document.createElement
	&&
	!(navigator.userAgent.indexOf('MSIE 5') != -1 && navigator.userAgent.indexOf('Mac') != -1)
	);

if (compatible)
{
	document.write('<style>.accessibility{display: none}</style>');
	var waitingRoom = document.createElement('div');
}

var hiddenFormFieldsPointers = new Object();

function prepareForm()
{
	if (!compatible) return;
	var marker = document.createElement(containerTag);
	marker.style.display = 'none';

	var x = document.getElementsByTagName('select');
	for (var i=0;i<x.length;i++)
		addEvent(x[i],'change',showHideFields)

	var x = document.getElementsByTagName(containerTag);
	var hiddenFields = new Array;
	for (var i=0;i<x.length;i++)
	{
		if (x[i].getAttribute('rel'))
		{
			var y = getAllFormFields(x[i]);
			x[i].nestedRels = new Array();
			for (var j=0;j<y.length;j++)
			{
				var rel = y[j].getAttribute('rel');
				if (!rel || rel == 'none') continue;
				x[i].nestedRels.push(rel);
			}
			if (!x[i].nestedRels.length) x[i].nestedRels = null;
			hiddenFields.push(x[i]);
		}
	}

	while (hiddenFields.length)
	{
		var rel = hiddenFields[0].getAttribute('rel');
		if (!hiddenFormFieldsPointers[rel])
			hiddenFormFieldsPointers[rel] = new Array();
		var relIndex = hiddenFormFieldsPointers[rel].length;
		hiddenFormFieldsPointers[rel][relIndex] = hiddenFields[0];
		var newMarker = marker.cloneNode(true);
		newMarker.id = rel + relIndex;
		hiddenFields[0].parentNode.replaceChild(newMarker,hiddenFields[0]);
		waitingRoom.appendChild(hiddenFields.shift());
	}
	
	setDefaults();
	addEvent(document,'click',showHideFields);
}

function setDefaults()

Hi webmaster64,

We can't debug your code for you :-(

What do you see in your web browser JavaScript console? I'd expect there to be some errors showing up there.

One problem may be that you have defined an addEvent() function, this may conflict with the MooTools addEvent() method - my JavaScript knowledge isn't enough to be sure.

Bob

Hi Bob , starting the debug console in explorer 9 does not appear any error message. 😢
The javascript code is inserted with Load JS action in event On Load before Show html.
Thanks for your advice

Hi webmaster64,

Please post a link to the form so I can take a quick look.

Bob

Hi Bob,
unfortunately, I'm developing a form on a website offline on xampp platform so I can not link the URL. It's possible that there is a conflict between the Javascript code and Joomla Mootools ? In this case is there any remedy?
Thanks for your help

Hi webmaster64,

Yes, it's quite likely that there is a conflict between your code, the MooTools validation code (and maybe something else on the page). The solution is to debug the JavaScript errors :-(

Bob

Many users... same problem...
Some news about it?

Hi assopiz,

Same answer . . . debug the JavaScript on the page with the form, that's almost always the problem.

Bob
