Today I am going to build a little on the Jscript version of that concept to show you how to use this to determine the HTML rendered in an Iframe in the form OnLoad event.
There isn't much more to it, here goes!
1. Upload a blank or next to blank HTML page to act as a web resource placeholder that we will change in code and make note of the URL, we will use it in our Jscript.
Next, we need to modify yesterday's Jscript so that we are setting the Iframe source URL to the edited web resource in the appropriate place in the response after it is published.
I will re-paste the entire code here, make note of the publish response function of the entity and you will see where we are setting the Iframe source. All you have to do is publish an event handler in the GUI that calls the runme function of this library after you swap our your specific web resource GUID.
function runme() {
var guidWebResource = "ADFA33CB-7050-E011-9CF8-080027AD5B6E";
var strContentHTML = "<html><body><h1>HELLO WORLD!!<h1></body</html>";
var enc = encode64(strContentHTML);
SDK.SAMPLES.UpdateWebResourceRequest(guidWebResource, enc);
SDK.SAMPLES.PublishWebResourceRequest(guidWebResource);
}
function encode64(input) {
var keyStr = "ABCDEFGHIJKLMNOP" +
"QRSTUVWXYZabcdef" +
"ghijklmnopqrstuv" +
"wxyz0123456789+/" +
"=";
//input = escape(input);
var output = "";
var chr1, chr2, chr3 = "";
var enc1, enc2, enc3, enc4 = "";
var i = 0;
do {
chr1 = input.charCodeAt(i++);
chr2 = input.charCodeAt(i++);
chr3 = input.charCodeAt(i++);
enc1 = chr1 >> 2;
enc2 = ((chr1 & 3) << 4) | (chr2 >> 4);
enc3 = ((chr2 & 15) << 2) | (chr3 >> 6);
enc4 = chr3 & 63;
if (isNaN(chr2)) {
enc3 = enc4 = 64;
} else if (isNaN(chr3)) {

Thats all there is to it!
Now let's look at our result when we open the preview form, it takes about 1.5 seconds to show our updated Jscript on my low powered dev box.
I hope this helps!
