I am working with a combination of ColdFusion and JavaScript to perform a ping for a customer requested app (tried to disuade them from this, but they were adamant). Presently I am performing the ping by creating a list of ip addresses to ping and providing the customer with a checkbox next to each ip. As a customer clicks on the checkboxes I am firing off a seperate window which is running some ColdFusion and JavaScript to perform the ping. This seperate window then returns the status of those variables to a function that writes a value to a disabled textbox on the page. I am wondering if there is a cleaner way of doing this, specifically when writing out to the disabled textbox. I'd like to write the text directly to the HTML page if there is a way of doing so. I've put examples of my code below (somethings are hardcoded for ease of viewing).

else
document.#FormName#.pingableText[checkbox_key].value = "";
}
function ping(checkbox_key,ipAddress)
{
pingWindow = window.open("","pingWindow","status=yes,resizeable=no,scrollbars=no,width=1,height=1");
pingWindow.focus();
pingWindow.creator = self;
pingWindow.location.href = "#templatepath#/ping.cfm?checkbox_key=" + checkbox_key + "&ipaddress=" + ipAddress;
return;

document.#FormName#.pingableText[checkbox_key].value = pingable;
