I have an iframe in my web page. I modify the src property via javascript like so:
document.getElementById('myiframe').src = 'http://vimeo.com/videoid1';
document.getElementById('myiframe').src = 'http://vimeo.com/videoid2';
document.getElementById('myiframe').src = 'http://vimeo.com/videoid3';
However, everytime I do this, it's logged into the browser's history. So everytime I press back in the browser window, the iframe content goes from videoid3 to videoid2 to videoid1. If I press back again, the entire page goes back.
I would like to modify the iframe src with javascript WITHOUT logging an entry into the browser's history. So if i click the browser back button, the entire page goes back without updating the iframe.
I tried doing something like:
document.getElementById('myiframe').contentWindow.location.replace('http://vimeo.com/videoid1');
document.getElementById('myiframe').contentWindow.location.replace('http://vimeo.com/videoid2');
document.getElementById('myiframe').contentWindow.location.replace('http://vimeo.com/videoid3');
Although this made the browser back button behave the way I wanted to, it broke certain things in the vimeo video. Vimeo REQUIRES you to change urls via the iframe.src instead of contentWindow.location.replace().
As such, how do I modify the iframe.src WITHOUT logging into history?
Related This is actually one of the solutions I'm exploring to solve the main problem, which I posted here History object back button with iframes
don't change the src, just replace the old iframe with a new one?
<!doctype html>
<style>
iframe {
width: 300px;
height:300px;
}
</style>
<script>
var urls = ["http://bing.com", "http://google.com", "http://duckduckgo.com"];
function next() {
if(urls.length==0) return;
var original = document.getElementsByTagName("iframe")[0];
var newFrame = document.createElement("iframe");
newFrame.src = urls.pop();
var parent = original.parentNode;
parent.replaceChild(newFrame, original);
}
</script>
<p>let's test some iframes</p>
<button onclick="next()">next</button>
<iframe />
No history states. Same functionality. Everyone wins.
You can do something like this:
var iframe = $('#iframe')[0];
iframe.contentWindow.location.replace(newUrl);
