javascript Inline Validation

function ValidateForm(){
	var sMsg = ''; //error message displayed
	var firstfield = ''; //used for setting focus
	
	//repeat for each field to be validated
	if (document.getElementById("txtField1").value == '')
	{
		sMsg = sMsg + 'field1, ';
		if(firstfield == '')
		{
			firstfield = 'txtField1';
		}
	}
	
	if (document.getElementById("txtField2").value == '')
	{
		sMsg = sMsg + 'field2, ';
		if(firstfield == '')
		{
			firstfield = 'txtField2';
		}
	}
	
	if (sMsg != '' )
	{
		sMsg = 'Please enter your ' + sMsg + '\n';
	}

	if (sMsg != '' )
	{
		//alert(sMsg); //used for debugging
		document.getElementById("divError1").innerText = sMsg;
		document.getElementById("divError2").innerText = sMsg;
		if (firstfield != ''){document.getElementById(firstfield).focus();}
		return false;
	}
	else
	{
		return true;
	}
}
Validates a form (2 fields within) and instead of alerting the error(s), it displays them within 2 divs, which can be styled appropriately.
