Changing an iframe SRC dynamically

What I have and I need to do it work properly is when I'm in a "start page" and I click a button like this:
PAGE-1
Point A
It should send me to "another page" where I load dinamically an iframe taking each variable (shopID, type, max-levels and point) from the URL and print it like an iframe this way:
PAGE-2
<iframe id="frame" src="http://myappwebsite/resourcesiframe?shopId=3366&type=image&point=A" width=“XXX" height=“XXX"></iframe>
I've used this javascript snippet but anyway, I can't make it work properly at all.
$(".map-button").click(function (e) {
e.preventDefault();
$("#frame").attr("src", $(this).attr('data - iframe - src'));
});
I only need to get the variables from the data-iframe-src and use them in the iframe, but I'm not able... The problem is that I load elements in different pages, so I don't know how this affect to the URL variables.

I've founded a simple solution for my problem here and it works for me.
First of all I put this simple iframe in my PAGE-2:
<iframe id="frame" src="" width="100%" height="auto" frameborder="0" scrolling="yes"></iframe>
Then in PAGE-1 I've used this type of links:
https://myappwebsite/page-2?shopId=1234&type=image&max-levels=1&point=A
So now my PAGE-2 loads properly with these params in the URL. Then I've used this simple snippet in Javascript to fill my iframe in PAGE-2:
<script type="text/javascript">
$( document ).ready(function() {
$("#frame").attr("src", "https://myappwebsite/resourcesiframe" + window.location.search);
});
</script>
And it works! Now I can go to PAGE-2 with all my params, pick them and use them in SRC inside the blank iframe.
Thanks for getting me in the correct path!

Iframe doesn't resolves the value from controller after the first load

I am using angular js frame work and has an iframe tag inside a ng-dialog. I am passing the src as
var SrcUrl=staticurl+dynamicUrl;
$scope.IframeSrcUrl=$sce.trustAsResourceUrl(SrcUrl);
and at the html
<iframe src="{{IframeSrcUrl}}" name="frame2" id="frame2" frameborder="0" marginwidth="0" marginheight="0" scrolling="auto" onload="" allowtransparency="false" height="350px" width="100%" ></iframe>
The iframe will resolves the proper url on its initial load.. but once if i close the ng-dialog and again open it; it will consider the "IframeSrcUrl" as string take it as a param for my base url and will return a 404 error.
i have tried ng-src instead of src.. but it also didn't works..
here staticurl is an externally hosted site and dynamicUrl is a dynamic genarated parameter. whenever i do some action , for instance a button click i need to start the ng - dialog box which redirects to the IframeSrcUrl via iframe.
now the problem is that , on second load the iframe considers IframeSrcUrl as a string and try to redirect to
"http://localhost:1337/%7B%7BIframeSrcUrl%7D%7D"

On load event of the dialox box, try this :
document.getElementById('frame2').src = document.getElementById('frame2').attr('data-src') and put the attribute data-src={{IframeSrcUrl}} on your iframe.

Print the iframe content

I want to print the content of the iframe. I viewd several examples but non of them helped me for my case. I have the following piece of code
<div id="print-area">
<iframe src='data:text/html;charset=utf-8,<?php echo $content ?>'></iframe>
</div>
And when the #print button is clicked: (this code prints out the content of the div #print-area)
$("#print").click(function (e) {
var newWindow = window.open();
newWindow.document.write($('#print-area').html());
newWindow.print()
});
The code works and print window is prompted, but when I try to put content of the iframe in the document.write(...) the function does not work. Any idea?
tried solutions:
Print iFrame content using Javascript
How to Print iframe content
and from other topics, but did not manage to print my iframe content

use
<iframe id="abcd" src='data:text/html;charset=utf-8,<?php echo "someHtmlContent" ?>'>
</iframe>
var newWindow = window.open();
newWindow.document.write($('#abcd').contents().find("html").html());
newWindow.print()
because iframe is a independent page it not access by windows class
that why use parent class

Issue in printing iFrame in Google Chrome

I have an iframe like
<iframe id="Frame1" name="Frame1" style="width: 810px;overflow:hidden;height:525px;border:none;"src="templates/template1.html">
</iframe>
When I click generate button
the generate function will call.In generate function i changed the src of the iframe to template2.html.
<input type="button" id="btngenerate" onclick="Generate();"/>
<a id="print" onclick="OnPrint();">Print</a>
When I click on the print link after clicking the generate button,I want to print the iframe.
function generate()
{
var billPath = "templates/template2.html";
$("#Frame1").attr("src", billPath);
}
function onPrint()
{
window.frames["Frame1"].window.focus();
window.frames["Frame1"].window.print();
}
It works in Firefox. But not in chrome.
In chrome the template1.html will be printed.I want to print template2.html.
When I call window.print(); it will print the whole page.
Please help me...

Is it possible for you to use a separate window to print your content (like I described here https://stackoverflow.com/a/23281929/701869) ?

Accessing element inside iFrame returning null

I have a form that posts to an iFrame. The website inside the iFrame is something I have no control over. However I would like to set the display of a few images inside the iframe to "none".
<form id="testForm" method="post" target="testFrame">
<input type="hidden" name="RequestXML" ID="RequestXML" value="<Request><RedirectURL>Account/TokenRequest</RedirectURL></Request>"
</form>
<iframe id="testFrame" name="testFrame" frameborder="0" style="width:1000px;height:500px"> </iframe>
Here is my script at the top of the page:
<script type="text/javascript">
$(function () {
$("#testForm").attr("action", "http://externalwebsite.aspx");
$('#testForm').submit();
var iframe = document.getElementById('testFrame');
var innerDoc = iframe.contentDocument || iframe.contentWindow.document;
//alert($("#testFrame").contents().find("body").html());
//alert(innerDoc.innerHTML);
});
</script>
Both my alerts return null in Chrome, IE and firefox. What is the best way to access the elements inside that iframe. (in chrome i dont even see the html of that website when I try to do "inspect element" and view the html)
By the way I am doing all this in a MVC4 project

Assuming this is not a cross-domain issue, try:
var body = $('#testFrame').contents().find('body');

Since this cross domain you have two options.
if you have access to the iframe code, then you can place XDM code in there, maybe easyXDM would help.
Or
you have to go server side and get your php/asp.net etc backend to go get the page and get what data it needs.
