Javascript Functions

The following is a few javascript functions to modify the DOM object.

function getVal(element)
{
	if (document.getElementById)
	{
		return document.getElementById(element).value;
	}
	else if (document.layers)
	{
		return document.layers[element].value;
	}
}

function setVal(element,val)
{
	if (document.getElementById)
	{
		document.getElementById(element).value = val;
	}
	else if (document.layers)
	{
		document.layers[element].value = val;
	}
}

function setHTML(element, val)
{
	if (document.getElementById)
	{
		document.getElementById(element).innerHTML = val;
	}
	else if (document.layers)
	{
		document.layers[element].innerHTML = val;
	}
}

function getHTML(element)
{
	if (document.getElementById)
	{
		return document.getElementById(element).innerHTML;
	}
	else if (document.layers)
	{
		return document.layers[element].innerHTML;
	}
}

• Set val to “none” to hide
• Set val to “block” or “inline” to display

function setDisplay (element, val)
{
	if (document.getElementById)
	{
		document.getElementById(element).style.display = val;
	}
	else if (document.layers)
	{
		document.layers[element].style.display = val;
	}
}

// This function pauses execution for x milliseconds
function pause(numberMillis) 
{
	var now = new Date();
	var exitTime = now.getTime() + numberMillis;
	while (true) 
	{
		now = new Date();
		if (now.getTime() > exitTime)
		return;
	}
}
