scrollHeight doesn't work since last Chrome update

I had this function for a long time and it made my iframe change height on click, but since the last update of chrome it stoped working on chrome. i get the value 0, while on explorer or other platform it works great. any ideas how to make it works again?
function calcHeight() {
var the_height = document.getElementById('resize').contentWindow.document.body.scrollHeight;
window.alert(the_height);
document.getElementById('resize').height= the_height;
}

You could try to change how you reference the document to:
var the_height =
document.getElementById('resize').contentWindow.document.documentElement.scrollHeight;

blur not working in safari

I'm looking to detect clicks in an iframe and based on this answer posted here a while ago (http://jsfiddle.net/oqjgzsm0/), I've got this piece of code working for all browsers except safari 9. For some reason, safari seems to not detect the elem.blur(); and keeps looping the action (in this case, a function call to refresh another iframe). Any ideas on how I can make this solution work for safari as well?
function reload() {
document.getElementById('iframe#2').src += '';
}
var monitor = setInterval(function(){
var elem = document.activeElement;
if(elem && elem.id == 'iframe#1'){
reload();
elem.blur(monitor);
return false;
}
}, 100);

window.print(); does not work in Safari

The print method does not work on window when using an onclick link Safari. What is the alternative to have a webpage print, in safari via onclick code that is placed on a button? Another odd behavior that's occurring is that when I try and close the window, the print dialog native to the browser then appears.

Try this solution:
try {
// Print for Safari browser
document.execCommand('print', false, null)
} catch {
window.print()
}

I was facing a similar issue with the Safari browser (and not any others).
In my case, aborting all API calls currently in progress immidiately showed the native print dialog.
I'm guessing the reason why your dialog showed up when trying to close the tab/page is that all the network requests are cancelled then.
Here's an example of how to create a pool of ajax requests (when using jQuery):
Stop all active ajax requests in jQuery
Also, to make it work consistently, I had to wrap the $.xhrPool.abortAll function in a short timeout (100ms).
My click handler function (simplified) looks something like this:
function myFunction() {
window.print();
window.setTimeout(function () {
$.xhrPool.abortAll()
}, 100);
}

If you return the result of window.print() to the onclick handler, Safari will not display the print window. I use React and had to make the following change:
//code that does not work:
<button type="button" onClick={() => window.print()}>Print!</button>
//code that does work:
<button type="button" onClick={() => { window.print(); }}>Print!</button>
All other browsers I tested (except Safari on iOS) worked fine either way, such as Chrome on iOS or Chrome for desktop.
My best guess is that as window.print is known to be asynchronous in Safari, perhaps window.print() returns falsy to the onclick handler, which cancels any "popups" from being displayed. This may be why the sample above with the myFunction() code may work when having onclick="window.print()" may not work.

This currently works in Firefox, Chrome and Safari:
try {
if(!document.execCommand('print', false, null)) {
window.print()
}
} catch {
window.print()
}

var frame1 = document.createElement('iframe');
frame1.name = "frame3";
frame1.style.position = "absolute";
frame1.style.top = "-1000000px";
document.body.appendChild(frame1);
var mywindow = frame1.contentWindow ? frame1.contentWindow : frame1.contentDocument.documentElement ? frame1.contentDocument.documentElement : frame1.contentDocument;
mywindow.document.open();
mywindow.document.write('<html><head><title>' + strTitle + '</title>');
mywindow.document.write('</head><body>');
mywindow.document.write(data);
mywindow.document.write('</body></html>');
mywindow.document.close(); // necessary for IE >= 10
setTimeout(function () {
window.frames["frame3"].focus(); // necessary for IE >= 10
window.frames["frame3"].print(); // necessary for IE >= 10
}, 500);
setTimeout(function () {
document.body.removeChild(frame1);
}, 20000);

Have no problem with window.print() with Safari. Sorry I could not try on Windows OS but follow code works for me with MacOS:
<!DOCTYPE html>
<html>
<body>
<button onclick="myFunction()">Click me</button>
Click link
<script>
function myFunction() {
window.print();
}
</script>
</body>
</html>

dynamically change onload for an iframe

I have a page containing a couple of <iframe> tags. I want to change their onload actions dynamically. I have the following code that works fine in FF, Safari, Chrome, Opera, but IE (8) refuses to comply.
document.getElementById('myiframe').onload = function() {
return function() { file_onLoad(data); }
}();
I've been using something similar for setting the onchange of an <input> element and this works well in all the browsers I've tested, including IE.
document.getElementById('myinput').onchange = function() {
return function() { file_onChange(data); }
}();
So I guess it has something to do with the way I'm getting the frame element / object.
I've also tried frames['myiframe'] but with no success.
Thanks for your help!

It works fine on mine...
I tried:
function whatever(){
document.getElementById('myiframe').src="http://www.google.com/"
document.getElementById('myiframe').onload = function() {
return function() { alert("Done."); }
}();
}
and it works. (I tried on IE9 with IE8 mode turned on)
If it does not work for you, try this:
document.getElementById('myiframe').addEventListener('load', file_onLoad, false);
