How would you link a custom iframe?

I am wanting to link an iframe that is untitled, and I have gotten some code that lets me create an iframe, I just cannot figure out how to link the iframe. My code just lets me open the iframes, and I cannot figure out how I could modify my code to make it linkable, and I have seen this done before, but I was wondering if anyone could help me. (I do use it as a bookmarklet as well)
Javascript:
(function() {
var win = window.open();
var f = win.document.createElement("iframe");
window.focus();
var url = win.prompt("enter url", "https://");
if (!url) return;
win.document.body = win.document.createElement("body");
f.style.width = "100vw";
f.style.height = "100vh";
win.document.body.appendChild(f);
f.src = url
})()

How can I open list of urls in one window?

I want to know how I can open a series of urls in one tab. I have a list of urls, and I just want to open each one so its contents will be cached, just using one open tab so I don't end up with dozens of open tabs.

Use ** iframes ** one for each URL.
They can be made borderless using CSS if desired.

This is the my solution for your problem:
Html
<button onclick="changeURL()">
Change URL
</button>
Javascript
var listOfURL = ["https://www.google.es",
"https://www.stackoverflow.com",
"https://www.youtube.com"
];
var indexURL = 0;
var iframe = document.createElement("IFRAME");
function changeIndexURL() {
indexURL += 1;
if (indexURL >= listOfURL.length) {
indexURL = 0;
}
}
function changeURL() {
iframe.setAttribute("src", listOfURL[indexURL]);
iframe.style.width = 640 + "px";
iframe.style.height = 480 + "px";
document.body.appendChild(iframe);
changeIndexURL();
}
changeURL();

Remove iframe after printing

I'm new to HTML and Javascript. I'm trying to write a Javascript function to print the content of an (hidden) iframe in order to print documents (to the user, seemingly) without opening them.
I based the function on the example I found here: https://developer.mozilla.org/en-US/docs/Printing#Print_an_external_page_without_opening_it
Printing the content works fine but the trouble is removing the iframe from the document after the printing has finished. This is what my code looks like now.
function closePrint () {
var element = document.getElementById("printFrame");
element.parentNode.removeChild(element);
}
function setPrint () {
this.contentWindow.__container__ = this;
this.contentWindow.onbeforeunload = setTimeout(closePrint, 100);
this.contentWindow.onafterprint = setTimeout(closePrint, 100);
this.contentWindow.focus(); // Required for IE
this.contentWindow.print();
}
function printPage (sURL) {
var oHiddFrame = document.createElement("iframe");
oHiddFrame.onload = setPrint;
oHiddFrame.width = 0;
oHiddFrame.height = 0;
oHiddFrame.style.position = "fixed";
oHiddFrame.style.right = "0";
oHiddFrame.style.bottom = "0";
oHiddFrame.id = "printFrame";
oHiddFrame.src = sURL;
document.body.appendChild(oHiddFrame);
}
I changed two lines in the example from
this.contentWindow.onbeforeunload = closePrint;
this.contentWindow.onafterprint = closePrint;
to
this.contentWindow.onbeforeunload = setTimeout(closePrint, 100);
this.contentWindow.onafterprint = setTimeout(closePrint, 100);
As it didn't remove the iframes without the timeout.
This works fine in both IE11 and Chrome, but in IE compitability mode (which I think emulates IE7) it gives me an error "Not implemented" when I try to use setTimeout.
So my question is, is there another way to run the closePrint function after a timeout or some other way to remove the iframe from the document when I've printed the content? Any help is appreciated.

after printing, leave the iframe on document.body. When you need to add your next iframe, first run a check for its presence ~ if its present, remove it then (first two lines).
myfunction() {
const iframe = document.querySelector('iframe');
if (iframe) iframe.parentNode.removeChild(iframe);
const i = document.createElement('iframe');
i.style.display = 'none';
i.src = this.study.DocumentUrl;
document.body.appendChild(i);
document.querySelector('iframe').contentWindow.focus();
document.querySelector('iframe').contentWindow.print();
}

refresh page after last appended iframe is loaded

I created a simple bookmarklet to append 3 invisible iframe's to the current document looking like this:
javascript: (function() {
var link = window.location.href;
var desktop = link.replace(".com", ".com/purge");;
var mobile = link.replace(".com", ".com/mpurge");
var tablet = link.replace(".com", ".com/tpurge");
var platforms = [desktop,tablet,mobile];
for (i = 0;i<platforms.length; i++){
ifrm = document.createElement("IFRAME");
ifrm.setAttribute("src", platforms[i]);
ifrm.style.width = 0+"px";
ifrm.style.height = 0+"px";
document.body.appendChild(ifrm);
if(i==platforms.length-1){
ifrm.onload = function(){
location.reload();
}
}
}
})();
what i want to do its to refresh the page im at after the third iframe is loaded but for some reason i cant get this one to work, any idea why?
thx!

i will never be == platforms.length inside of loop, because your loop condition is i<platforms.length.
Make it i == platforms.length - 1 or take reloading outside of the loop

javascript: IFrame-SRC as new Window?

I have a web application in which I have a bunch of iFrame from with source from other tools.
Now the user should have the possibility to open the iframe content in a new window / new tab, normaly I would simply add something like this:
function onButtonClick() { var src = $('#iframe').prop('src');
windows.open(src, "_blank"); }
But his would only open a new version of my iFrame context, e.g. if a user open a page in the iframe or clicked on something and javascript changed something within my iframe, the user would be loosing this value..
So, can I make a iframe Content to a new window content without loosing the dynamic state of the website within my iframe?

You cannot move around iframes between different windows without reloading, because the spec says the attributes must be reevaluated:
When an iframe element is inserted into a document that has a browsing context, the user agent must create a nested browsing context, and then process the iframe attributes for the "first time".

Old answer:
// edit: Does not work as expected, since the iframe is reloaded on move and the original src is restored.
It is easy enough if you move the iframe out of the current page:
<button id="example-button">open in new window</button>
<div id="example-container">
<iframe id="example-iframe" src="https://example.com/">
</iframe>
</div>
document.getElementById('example-button').addEventListener('click', function (ev) {
ev.preventDefault();
var win = open('about:blank');
var iframe = document.getElementById('example-iframe');
// the popup might not be immediately available:
setTimeout(function () {
var body = win.document.body;
body.style.padding = 0;
body.style.margin = 0;
body.appendChild(iframe);
iframe.style.position = 'fixed';
iframe.style.padding = 0;
iframe.style.margin = 0;
iframe.style.width = '100%';
iframe.style.height = '100%';
iframe.style.border = 0;
}, 0);
// move the iframe back if the popup in closed
win.addEventListener('beforeunload', function () {
document.getElementById('example-container').appendChild(iframe);
iframe.style.position = '';
iframe.style.padding = '';
iframe.style.margin = '';
iframe.style.width = '';
iframe.style.height = '';
iframe.style.border = '';
});
});
