Next, I added Eric Costello’s IFrame code to the searchForm.js file:
<?php
var IFrameObj;
// our IFrame object - global
function callToServer(term)
{
if (!document.createElement) {return true};
var IFrameDoc;
//var URL = 'server.html' + buildQueryString(theFormName);
var URL = './server.php?s='+term;
if (!IFrameObj && document.createElement)
{
// create the IFrame and assign a reference to the
// object to our global variable IFrameObj.
// this will only happen the first time
// callToServer() is called
try
{
var tempIFrame=document.createElement('iframe');
tempIFrame.setAttribute('id','RSIFrame');
tempIFrame.style.border='0px';
tempIFrame.style.width='0px';
tempIFrame.style.height='0px';
IFrameObj = document.body.appendChild(tempIFrame);
if (document.frames)
{
// this is for IE5 Mac, because it will only
// allow access to the document object
// of the IFrame if we access it through
// the document.frames array
IFrameObj = document.frames['RSIFrame'];
}
}
catch(exception)
{
// This is for IE5 PC, which does not allow dynamic creation
// and manipulation of an iframe object. Instead, we'll fake
// it up by creating our own objects.
iframeHTML='<iframe id="RSIFrame" style="';
iframeHTML+='border:0px;';
iframeHTML+='width:0px;';
iframeHTML+='height:0px;';
iframeHTML+='"></iframe>';
document.body.innerHTML+=iframeHTML;
IFrameObj = new Object();
IFrameObj.document = new Object();
IFrameObj.document.location = new Object();
IFrameObj.document.location.iframe = document.getElementById('RSIFrame');
IFrameObj.document.location.replace = function(location)
{
this.iframe.src = location;
}
}
}
if (navigator.userAgent.indexOf('Gecko') !=-1 && !IFrameObj.contentDocument)
{
// we have to give NS6 a fraction of a second
// to recognize the new IFrame
setTimeout('callToServer()',10);
return false;
}
if (IFrameObj.contentDocument)
{
// For NS6
IFrameDoc = IFrameObj.contentDocument;
}
else if (IFrameObj.contentWindow)
{
// For IE5.5 and IE6
IFrameDoc = IFrameObj.contentWindow.document;
}
else if (IFrameObj.document)
{
// For IE5
IFrameDoc = IFrameObj.document;
}
else
{
return true;
}
IFrameDoc.location.replace(URL);
return false;
}
?>
