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!

Embed (iframe or object) and Modify (jQuery) webpage

I'm simply trying to load another webpage in my webpage using the object tag or iframe. Then, I would like to remove some element of the loaded page with jQuery.
Here is my code
<div>
<object type="text/html" data="http://ebird.org/ebird/map/eurtre1" width="100%" height="400px" id="eurtre1">
</object>
</div>
<script>
jQuery( window ).load(function() {
jQuery('#map-sidebar').remove();
});
</script>
And, as you guess, it is not working...
I have tried:
jQuery('#eurtre1').contents().find('#map-sidebar')
and
jQuery('#eurtre1')[0].contentDocument.children
The wired thing is that on my browser, I can do it in the console, once I've selected the inside of the object...
Any idea ?

Here's a link to a similar question:
how to access an iframe and affect it with jQuery
Basically you can't due to Javascript same-origin policy but if you have access to the loaded content in the iframe you could use window.postMessage
You could also add a parameter to the iframe's src tag to post a message, something like this:
<iframe src="http://www.example.com?hideElement=true"></iframe>
Again you will have to have access the content of the iframe to check the param and execute your code.

Unable to change HTML iframe source with Javascript

I'm trying to have a 'video of the day' on my website. I currently have most of this working, and here's how I plan to have it working in the end:
Have a Python script run once every 24 hours to pick the random YouTube video of the day
Write the embedded video URL to a text file
Use Javascript to access the text file and grab the video URL, and use it as the iframe source on my webpage
As I mentioned above, this plan is currently working for the most part. My script is able to pick the random video, and write it to a text file. My web page is then able to pull the video URL from the text file, and write it to the webpage in text form. However, I'm having some troubles having it write the video URL to my iframe.
I did some searching, and people suggested trying the following code:
<iframe id="mainvideo" width="720" height="480" frameborder="0" src="" allowfullscreen></iframe>
<script>
document.getElementById("mainvideo").src =
finalresult + ReturnURL();
</script>
So earlier in my code, I declared the variable 'finalresult' to be the following value: //www.youtube.com/embed/WJDnJ0vXUgw
When I have Javascript write 'finalresult' to my webpage, it will write the video URL as text to the webpage as expected. However, when I try and declare it as the source for the iframe, I end up with a blank iframe on the page.
Does anyone know what the problem is with my code for it not showing this video in my iframe? Any help would be appreciated.

You must be changing the src after any particular event is fired. So try this way,
HTML :
<iframe id="mainvideo" width="720" height="480" frameborder="0" src="http://www.bing.com/" allowfullscreen></iframe>
<button id="changeSrc">Change iFrame</button>
javaScript :
var iframe = document.getElementById("mainvideo");
changeSrc.onclick = function(){
iframe.src = "http://www.w3schools.com/";
};
jsFiddle
Update 1 :
If you want to change the iframe src attribute after page load then go with this way,
window.onload = function(){
var iframe = document.getElementById("mainvideo");
iframe.src = "http://www.w3schools.com/";
};
jsFiddle

If myframe.src does not work for you, then try out myframe.contentWindow.location.href like in this pen.

JS include URL as URL parameter

I have this script in JS which uses URL parameter for image location, it works fine when image is located in the same place as the script like below
<iframe src="pan.htm?image=img1.jpg" ></iframe>
But I need it to get the image from other location, how do I do it I tried the way below but it doesn't work this way (url is just an example)
<iframe src="pan.htm?image=http://someaddress.com/img1.jpg" ></iframe>

You need to encode the url. You can do this by running this script:
prompt('Here is your completed code:',encodeURIComponent(prompt('Enter the url to encode','')));
You can try it out here: http://jsfiddle.net/zenr8/
The encoded URL that the script gives you is the thing you need to enter into the URL parameter. In your case, the iframe would look like this:
<iframe src="pan.htm?image=http%3A%2F%2Fsomeaddress.com%2Fimg1.jpg" ></iframe>
If you need to enter something in an URL parameter from a script, you should always make sure that it's properly encoded. You can do this by using encodeURIComponent. If you then need to decode it for further usage in your script, just use decodeURIComponent again. For example:
alert(encodeURIComponent('http://google.com/?hl=en&q=search'));
//alerts http%3A%2F%2Fgoogle.com%2F%3Fhl%3Den%26q%3Dsearch
alert(decodeURIComponent('http%3A%2F%2Fgoogle.com%2F%3Fhl%3Den%26q%3Dsearch'));
//alerts http://google.com/?hl=en&q=search

You need to urlencode the parameter.
<iframe src="pan.htm?image=http%3A%2F%2Fsomeaddress.com%2Fimg1.jpg" ></iframe>
This could be done using php for example:
<iframe src="pan.htm?image=<?php echo urlencode("http://someaddress.com/img1.jpg"); ?>" ></iframe>
Or with javascript itself:
var iframe = document.createElement("iframe");
iframe.setAttribute("src","pan.htm?image="+encodeURIComponent("http://someaddress.com/img1.jpg"));
var wrapper = document.getElementById("iframe_wrapper");
wrapper.appendChild(iframe);

How does target="framename" work when iframe DOM has changed

I know iframes are evil, but mine is legacy app n I need to use iframes in it. So...
I need to create n display tabs of iframes dynamically for my web app. All frame sources are intra-domain so full traversal n access within the frames possible.
The problem with iframes n the DOM is that these iframes register as window.frames.framename, so I will have an array of those objects in the "frames" object.
My requirement states that the "active" frame must have the name "form". So I change that iframe attribute when setting that frame as active. But this doesn't reflect in the DOM as window.frames.form, so I change that too manually by setting the current frame object like this:
frames.form = my_frame.content Window
All this works fine n I'm able to now access everything in n out of the active "form" iframe properly.
The problem now is with my links in the main page that have target="form". The target is not being recognized as the latest set (active) iframe with the name "form", n hence that link when clicked opens up in a new window/tab in the browser. This behavior is in all browsers except firefox. (Firefox does the required thing: open those links in the latest form iframe)
I suppose I don't have the knowledge of how the browser manipulates such changes in the DOM related to iframes. So any help would be appreciated. Thanks!
UPDATE:
Here's a simplified code (note: not original code): http://jsfiddle.net/u4VJL/5/
function AddNewTab(e) {
$('#list').attr('id', 'nolist').attr('name', 'nolist');
$('#form').attr('id', 'noform').attr('name', 'noform');
$(document.body).append('<iframe id="list" name="list" src="" marginwidth="0" marginheight="0" scrolling="auto" frameborder="1" class="form" style="width:22%"></iframe>');
$(document.body).append('<iframe id="form" name="form" src="" marginwidth="0" marginheight="0" scrolling="auto" frameborder="1" class="form" style="width:74%"></iframe>');
frames.list = $('#list')[0].contentWindow;
frames.form = $('#form')[0].contentWindow;
return false;
}
$('#addnew').click(AddNewTab);
Steps to reproduce the issue:
Click the "Add new tab" link once.
Click "Sample link" - and that href will load in the right frame
named "form".
Click "Add new tab" again. A new set off iframes should show up.
Click "Sample link" again. The page should now load in the 2nd right
frame, but it loads in first.
NOTE: Browsers with this issue (that I've tested in): Google Chrome,
IE8. Firefox does not have this issue.

you need to use live:
$('#addnew').live("click", AddNewTab);
uhh, it was a wrong answer, i think you need to look this way:
$("a[target=form]").click( function(){
$("#form").last().attr("src", $("a[target=form]").attr("href"));
$("#form").reload();
return false;
});
this works

frame name indeed. This works (in Firefox, Chrome, and IE8 n above):
function AddNewTab(e) {
$('#list').attr('id', 'nolist').attr('name', 'nolist');
$('#form').attr('id', 'noform').attr('name', 'noform');
if (frames.list) frames.list.name = 'nolist';
if (frames.form) frames.form.name = 'noform';
$(document.body).append('<iframe id="list" name="list" src="" marginwidth="0" marginheight="0" scrolling="auto" frameborder="1" class="form" style="width:22%"></iframe>');
$(document.body).append('<iframe id="form" name="form" src="" marginwidth="0" marginheight="0" scrolling="auto" frameborder="1" class="form" style="width:74%"></iframe>');
frames.list = $('#list')[0].contentWindow;
frames.form = $('#form')[0].contentWindow;
frames.list.name = 'list';
frames.form.name = 'form';
return false;
}
$('#addnew').click(AddNewTab);

((PS: tchh!! I swear I had tried this but couldn't make it work before. Anyway, I guess I was wrong when I thought I tried it. Thanks all!!))
