Well the three links I posted have wonderful examples, but here is some
extensively snipped bits of code from a chat application I threw together
experimenting one night. This is an IE/Mozilla solution only though.
<style>
#pipeFrame {
display: none;
}
</style>
<script language="JavaScript" type="text/javascript">
function sendData(txt) {
datapipe = document.getElementById("pipeFrame");
datapipe.src = "chatrow.cfm?newtext=" + txt;
}
function setData(txt) {
document.getElementById("serverdata").value = txt;
}
</script>
<input type="text" id="serverdata">
<iframe id="pipeFrame" src=""></iframe>
All you have to do is fire the sendData function with the text to send to
the server as the only parameter.
---chatrow.cfm---
<script language="JavaScript">
<cfloop from="1" to="#arrayLen(application.chatStr.chat)#" index="i">
parent.setData('<cfoutput>#urlEncodedFormat(application.chatStr.chat[i])#</c
foutput>');
</cfloop>
</script>
I snipped the array setup and some other things but the key is that this
function calls the frames parent function but sends back whatever you want
back to the original page.
A bit more than five lines I guess, but close :)
