Javascript validation error

JavaScript
1

this is how i call the editor:


	<!-- editor -->
	<? include "js/editor/buttons.php"; ?>
	<iframe id="textbox" class="Eddietor" src="js/editor/editor.php"></iframe><br />
	<input type="hidden" id="content" name="content">
	<!-- /editor -->

and this is editor.js:


window.onload = function()
{
	Editor = document.getElementById('textbox').contentWindow.document;
	Editor.designMode = "on";
	document.forms[0].onsubmit = function()
	{
		var text = document.getElementById('text');
		text.value = Editor.body.innerHTML;
	}
}

function doColor(colour)
{
	document.getElementById("textbox").contentWindow.focus();
	document.getElementById("textbox").contentWindow.document.execCommand("forecolor",false, colour);
}



function doClick(command) {
document.getElementById("textbox").contentWindow.focus();
document.getElementById("textbox").contentWindow.document.execCommand(command, false, null);
}
function doLink() {
var mylink = prompt("URL:", "http://");
if ((mylink != null) && (mylink != "")) {
document.getElementById("textbox").contentWindow.focus();
document.getElementById('textbox').contentWindow.document.execCommand("CreateLink",false,mylink);
}
}
function doImage() {
myimg = prompt('URL:', 'http://');
document.getElementById("textbox").contentWindow.focus();
document.getElementById('textbox').contentWindow.document.execCommand("InsertImage", false, myimg);
}

another script i made is having problems with the ID=“textbox” , it might be fixed if i change id and start using name=“textbox” instead,
but i don’t know how to do this in js. need to edit the editor.js and change id=“textbox”->to->name=“textbox”
can anyone help me? i got no idea how to use the getElementByName thingie , i’m trying to do this for 4 hours already and still no go.

appreciated.

What problems? What part of the other script is causing the problem?

It sounds like the other script is broken and that’s what you need to fix.

function validateEmpty(fld) {
    if (fld.value.length == 0) {
        fld.style.background = '#FFB2B2';
        error = "The required field has not been filled in.\
"
    } else {
        fld.style.background = 'White';
    }
    return error;  
}

// ******************
// USERS
// ******************
function validateForm_users(theForm) {
var reason = "";
	reason += validateEmpty(theForm.username);	
	reason += validateEmpty(theForm.db_name);
	reason += validateEmpty(theForm.db_user);
	reason += validateEmpty(theForm.db_pass);
  if (reason != "") {
    alert("EMPTY PLEASE TRY AGAIN");
    return false;
  }
  return true;
}


// ******************
// PAGES
// ******************
function validateForm_pages(theForm) {
var reason = "";
	reason += validateEmpty(theForm.title);
	reason += validateEmpty(theForm.name);
  if (reason != "") {
    alert("EMPTY PLEASE TRY AGAIN");
    return false;
  }

}

this is the script for validating empty forms
maybe it is broken? can you tell me if you see any errors in it
