how to change the iframe? - javascript

I have 2 iframes in my page. Both have the same source. When I change the 1st iframe, the changes must be reflected in 2nd one. It looks like remote browsing. How can I achieve this in javascript?

var iframes = document.getElementsByTagName('iframe');
var src = iframes[0].src;
iframes[1].src = src;
Without knowing what your page does or seeing any code can't really give you more then this...

If you're using jQuery:
var frames = $('iframe');
frames.each(function() {
this.attr("src", yourUrl);
});

get a dynamic id from an iframe in an iframe

I am actually doing a tricky task, I have to create pack of resource(which are pages on the website), to do so I use iframe to display the content of the pages. But I can have multiples Iframes in one Iframe.
And I want to pass some style on those iframe in iframe, so i have to target them.
I have a special node id for each pages that allow me to return only the body.
So my question is how do I get to target the id of my iframe in my iframe which I tried to do with that line var get_iframe_inside = search_inside.getElementsByTagName("iframe".id); to then modify it's style.
I know that I am not using the right way for this line, but I have been scratching my head all this morning and can't find a way.
function test(id){
var iframe = window.parent.document.getElementById(id); //select my first iframe
get_iframe_inside(id); //call my function to get the iframe in the iframe
function get_iframe_inside (id){
var search_inside = (iframe.contentDocument) ?iframe.contentDocument : iframe.contentWindow.document;
//My goal is then to modify some properties
var get_iframe_inside = search_inside.getElementsByTagName("iframe".id);
$(get_iframe_inside).css({'padding':'0px 50px', 'background-color':'#cecece'});
}
}
Well it was kind of trivial my code was nearly working i just didn't tought at how to get thoses ids.
i just had to get them by tag and after that to do an iteration with for.
var get_iframe_inside = search_inside.getElementsByTagName("iframe");
var i;
for (i = 0; i < get_iframe_inside.length; i++){
get_iframe_inside[i].style.padding='0px 50px';

How to enable the design mode of iframe?

I have tried to edit div text which I open in an iFrame like this:
$(function() {
var iframeBody = $("#texteditor").contents().find("body");
var styleTag = iframeBody.append($('#content'));
iframeBody.designMode = "on";
})
and the page look llike this:
I am trying to edit the text, but it's not working
Try instead
var iframe = $("#texteditor <iframe-selector>");
var jqIframeBody = $(iframe[0].contentDocument.body);
Basically you cannot write a absolute selector starts from your parent window contents, you need to first get into the context (window/document) of iframe and then perform dom operations, or messaging through 1postMessage` however you want.

links within an iframe window to open in new tab

I have seen this question many times, and a lot of the answers seem to suggest the base target="_blank" technique. However, I have used this before in the past; but my current page it does not work. I also don't think it could be best option even if it did work; as I ONLY want the links within the iframe src="" to open in a new window. I am hopping there's a simple solution I can add inline to the page. I have also tried adding an id as below, and using JavaScript, still nada.
<iframe src="mywordpressfeed.html" id="frame1" width="310" height="380"></iframe>
JS
$(document).ready(function(){
$("#frame1").attr("target","_blank");
});
Basically the goal is to when a user sees my wordpress feed within the iframe I have on a static page; once the post title is clicked it loads in a new window - as now it loads within the same iframe so there isn't an increased level of readability.
There is no real solution to this, due to the iFrame tag being developed for the opposite.
//pass the iframe to this iframe getting function
function iframeRef( frameRef ) {
return frameRef.contentWindow ? frameRef.contentWindow.document : frameRef.contentDocument
}
//Get Iframe
var inside = iframeRef( document.getElementById('iframeID') );
//Get all links
var links = inside.getElementsByTagName('a');
//Loop throught links and set their attributes
for (var i = 0 ; i<links.length ; i++){
links[i].setAttribute('target','_blank');
}
//No jQuery needed!
thanks to meder
EDIT
Due to iframe same source restrictions I had to find a website with inner iframe from same source so you can paste this code
//pass the iframe to this iframe getting function
function iframeRef( frameRef ) {
return frameRef.contentWindow ? frameRef.contentWindow.document : frameRef.contentDocument
}
//Get Iframe
var inside = iframeRef( document.getElementById('IFwinEdit_Gadget_247730_3349') );
//Get all links
var links = inside.getElementsByTagName('input');
//Loop throught links and set their attributes
for (var i = 0 ; i<links.length ; i++){
links[i].setAttribute('style','background:red');
}
//No jQuery needed!
to the console in this web site and see the inputs change color

Get specific content in iframe without jquery

i want to get spesific contents (all of spans in .y6) in iframe without jQuery,
How can i write it only javascript?
"#canvas_frame" is an iframe
spans = $("#canvas_frame").contents().find(".y6>span");
If the iframe is on the same domain as the parent page you can use the iframe's contentWindow property.
Something like the below should help you out:
var canvasFrame = document.getElementById('canvas_frame').contentWindow,
allSpans = canvasFrame.document.getElementsByTagName('span'),
spans = [],
i;
i = allSpans.length;
while(i--){
if(/y6/.test(allSpans[i].parentNode.className)){
spans.push(allSpans[i]);
}
}

Reload iframe src / location with new url not working in Safari

I have a page that loads with initially just a form within an iframe, something like this:
<iframe id="oIframe" ...src='somePage>'
<form ... />
</iframe>
When you click a button in the form, some javascript is invoked that builds a url and then I want to do the following:
frame.src = 'somePage?listId=1';
This works in IE to "reload" the frame with the new contents.
However, in Safari this does not work.
I have jQuery available, but I don't want to replace the existing iframe because there are events attached to it. I also can not modify the id of the iframe because it is referenced throughout the application.
I have seen some similar issues but no solutions that seem to work well for my exact issue.
Any assistance anyone can provide would be great!
Some browsers don't use "src" when calling the javascript object directly from the javascript hierarchy and others use "location" or "href" instead of "src" to change the url . You should try these two methods to update your iframe with a new url.
To prevent browser cache add a pseudo-random string like a number and timestamp to the url to prevent caching. For example add "new Date().getTime()" to your url.
Some calling examples:
document.getElementById(iframeId).src = url;
or
window.frames[iframeName].location = url;
I recommend the first option using document.getElementById
Also you can force the iframe to reload a page using
document.getElementById(iframeId).reload(true);
So the answer is very simple:
1. put a <div id="container"> </div> on your page
2. when reload needed use following jQuery:
$("#container").empty();
$("#container").append("<iframe src='" + url + "' />");
and that's it.
Of course there is more elegant way of creating DOM with jQuery but this gives the idea of "refreshing" iframe.
Works in FF18, CH24, IE9, O12 (well it's jQuery so it will work almost always :)
I found a better solution (albeit not paticularly eloquent) for this using jQuery.ajax:
jQuery.ajax({
type: 'GET',
url: "/somePage?someparms",
success: function() {
frameObj.src = "/somePage?someparms";
}
});
This forces the DOM to be read within the frame object, and reloads it once the server is ready to respond.
Try this
form.setAttribute('src', 'somePage?listId=1');
Well, I was able to find what appears to be a feasible solution -- it's a work in progress, but this is basically what I ended up doing:
var myFrame = document.getElementById('frame'); // get frame
myFrame.src = url; // set src attribute of original frame
var originalId = myFrame.id; // retain the original id of the frame
var newFrameId = myFrame.id + new Date().getTime(); // create a new id
var newFrame = "<iframe id=\"" + newFrameId + "\"/>"; // iframe string w/ new id
myFrameParent = myFrame.parentElement; // find parent of original iframe
myFrameParent.innerHTML = newFrame; // update innerHTML of parent
document.getElementById(newFrameId).id = originalId; // change id back
I ran into this issue using React, passing the key as props.src solved it
const KeyedIframe = ({children, ...props}) => <iframe key={props.src} { ...props}>
{children}
</iframe>
