What I would like to do is change the content of a div based on the different links clicked on the same page. Can anyone point me in the correct direction? AFAIK it could be dangerous to insert scripts directly into a page, changing text works okay but it seems I'm not sure about scripts. The content of the scripts are embed codes for video streaming. I realise this may not be the right way to go about it. My attempt won't work because of escaping the '<,>' characters and passing the parameter only seems to accept text with no spaces.
The way I've attempted it is as follows (in pseudocode);
function changeVideo(script){ div.innerhtml=script;}
then links that change the content of the div;
<a href='#' onclick=changeVideo('<iframe src=justin.tv etc..></iframe>')>
<a href='#' onclick=changeVideo('<iframe src=ustream.tv etc..></iframe>')>
You could drop the use of JavaScript and create an iFrame with a specified name to host the content; while giving the links a target tag. Thus making any links with the target tag specified appear within the named iFrame.
However if you insist upon using JavaScript you could consider the use of AJAX.
I suggest you to locate your a elements with unobstrusive Javascript, with getElementById() for example.
Once you have got them in variables like, lets say, a1 and a2, and the iFrame is in variable iframe do a code like this.
// ...a1 and a2 are anchors and iframe is the frame.
var srcSwitch = function(e)
{
e.preventDefault(); // this will prevent the anchor from redirecting you
iframe.src = this.src; // this changes the iFrame‘s source
};
a1.addEventListener('click', srcSwitch, 1);
a2.addEventListener('click', srcSwitch, 1); // and we register event listeners.
With this code, there is no need to insert Javascript within HTML attributes and you must only put the script URL in the anchors SRC attributes.
Tell me how it goes, greetings.
I may have generalised the question too much.
So I want to embed a stream on clicking a link. If the link is something like a proper URL
http://Jimey.tv/mystream
the iframe works, but loads the whole page. But I want to use the stream embed code to get just the player
The embed code looks similar to;
<script type = text/javascript> channel='mychannel' w='620' h='400'</script><script type=text/javascript> src="jimmy.tv/embed.js></script>
My original JavaScript method doesn't work because of escaping the < characters, and passing the embedcode seems to be problamatic. Hopefully I've made this a bit clearer?
<script>
iframe1 = '<iframe frameborder="0" scrolling="no" id="chat_embed" src="http://twitch.tv/chat/embed?channel=xenema&popout_chat=true" height="301" width="221"></iframe>'
</script>
link 1
link 2
<div id="videos">diiiiv</div>

Can you load a page into an iframe with JQuery? I have a page that creates a custom printable pdf and need it to load into an iframe to make it easier for the user. I use jquery to pull in all the variables otherwise I could have it load within the page. I am not sure what I am missing with this command to load the page within id="print_form_modal2"?
$.frameReady(function(){
$("#print_form").prepend('<div id="newDiv"></div>');
$('#newDiv').load("print_audit.php?auditID="+auditID+"&action=print&print_name="+print_name+"&print_orient="+print_orient+"&download_option="+download_option+"&type=pdf");
}));
<iframe id="print_form_modal2" name="iFrame" src="">
You could do it the painless way and just use HTML:
Make an <a>nchor with the href to your PDF.
Add an iframe with a name attribute (ex. name="iframe1")
Next, add a target="iframe1" to the <a>.
PLUNKER
Its simple enough to do what you're trying to do using just JavaScript and HTML
HTML:
<iframe id="print_form_modal2" name="iFrame">
JavaScript:
function openIframe() {
document.getElementById("print_form_modal2").setAttribute("src", "https://www.example.com/");
}
You can see the code in a CodePen here: http://codepen.io/anon/pen/VjbBbY
In your code you need to replace https://www.example.com/ with the source path for PDF you wish to display, and change when openIframe is called to suit your requirements.
Here's a link to the codepen example
What you want to do on document ready (or whatever event is relevant to your logic) get the iframe and using the attr method change its source property to point to whatever new/old source.
Like this:
$(document).ready(function() {
$('#iframe-container').attr('src','http://www.w3schools.com/tags/tag_iframe.asp');
});
I'm trying to load a parent page into an object tag, and whilst I can get an alert to show I've got the code, I cannot get it into the <object> Any clues?
var page=parent.document.documentElement.innerHTML;
alert(page);
document.getElementById('close_skin').style.visibility="visible";
document.getElementById('show_skin').style.visibility="visible";
document.getElementById('show_skin').setAttribute("data",page);
Assuming I can get the code to appear, how can I "toggle" to a different set of styles? The parent uses ".xxx_fixed" classes, but the code in the object needs to use the ".xxx_float" classes that are also in the template CSS at top of page. (When I did it in another PERL program, it was easy just to rename the tags in the <body> from "class='xxx_fixed' " to "class='xxx_float' " (Can't do that so easily with global javascript replace as that would also rename the classes at top of code as well!)
I have just tried adding some script to the top of the var page object - which MAY work if I can get the code to appear ...
+'document.getElementById(\'icon_outer\').setAttribute(\'class\', \'icon_outer_float\')'
If you're interested as to the "why", the "fixed" keep menu / top bar fixed in one place when viewed in full screen browser, but the 'float' makes everything move in unison within the <object> "window" allowing viewer to pan around the template page like a static magnifying glass;
.menu_back_float{position:relative;top:0px;background-color:#f5eca4;min-height:520px;height:auto}
.menu_back_fixed{position:relative;top:35px;background-color:#f5eca4;min-height:550px;height:auto}
To load the parent page into an <object> element, you have to specify the URL of the page. To get the code and place it in a alert box, you can use jQuery's $.get() method (as long as you load it via a proxy domain), like this:
HTML:
// I'm just using W3Schools just to save time
<object data="http://www.w3schools.com/" width="1500" height="1200">
<embed src="http://www.w3schools.com/" width="1500" height="1200"></embed>
Your browser does not support the object tag.
</object>
JavaScript:
window.jQuery.get("http://www.yourdomain.com/?url=www.w3schools.com", function(response) {
window.alert(response);
}
For the second part of your question, you can use jQuery to change the name of the class from .xxx_fixed to .xxx_float:
function main() {
$('object').removeClass('xxx_fixed').addClass('xxx_float');
}
$(document).ready(main);
Hopefully I have answered your question correctly and thouroughly, and if I haven't, feel free to let me know so I can edit this.
I have a URL that resides on another domain, like this:
http://ads.adserver.com/ad?site=1233&zone=45435
When you type this URL in the browser, the result is HTML like this:
<img src="htt://ads.adserver.com/i/image.gif" border="0"/><br/>Test
The above renders as an image wrapped in a link with a second link below it.
I tried to capture this URL in a script tag and append it to the DOM, but it does not render the HTML above.
var ad_script = document.createElement('script');
ad_script.type = 'text/javascript';
ad_script.src = 'http://ads.adserver.com/ad?site=1233&zone=45435';
li.appendChild(ad_script);
Are there any other ways of invoking this URL and putting the result on the page? I can't use $.getScript() since I'm not invoking this in the global context. I need this HTML to appear exactly where I want it to appear.
EDIT: The only reason I am trying this route is that the third-party does not provide a JSON-P interface.
EDIT2: Unfortunately, I am not on an application server.
EDIT3: This is for iPhone.
You are limited to how you load this due to cross-domain issues .. an easy way would be to load the image in it's own iframe
<iframe src='http://ads.adserver.com/ad?site=1233&zone=45435' height='200px' width='200px' />
You'll want to use ajax for this. The easiest way might be jQuery's .load() method.
Assuming the element you want the content to go into has an id of holder, you would do
('#holder').load('http://ads.adserver.com/ad?site=1233&zone=45435')
It will put the contents of the webpage into your selected element. http://api.jquery.com/load/
edit: Sorry, forgot cross-site ajax limitations. You could instead set up a php page like:
if(isset($_GET['url'])){
echo file_get_contents($_GET['url'])
}
and then do
('#holder').load('http://yoursite.com/yourpage.php?url=http://ads.adserver.com/ad?site=1233&zone=45435')
Take the jsonp approach. use an actual script tag and put an executing javascript function as the response that adds that html markup to the dom. It will add it to the dom of the page where the script tag resides.
There are a number of jQuery ajax calls that can accomplish this, for example:
jQuery.get('http://ads.adserver.com/ad?site=1233&zone=45435', function(data){jQuery(updateElementQuery).html(data);});
Try to use jquery method 'load'
`$('#result').load(url, function(response) {
$('#my-li').append($('#result').html());
$('#result').html(null);
});`
... where #result is some hidden div
I need to be able to open a link to a specific URL that is within an iFrame; the link is generated by php and I can't change the source code, so I need to change the link in the iFrame dynamically, if possible.
What I'm doing is this: on a non-profit organization's site, I have an affiliate store (generated by php) displayed within an iFrame on a page in order to make it more styled with the rest of the site. The php store pulls products from an affiliate service; the link to the store.php is in the same domain as the main non-profit's site.
The problem is the final "Buy Now" link from a product opens the final destination e-commerce store within the iFrame, and as such the page is stuck in the iFrame and looks bad and one must scroll V and H to see it and check out.
The link I need to open in a new window always has the class "av_buy_now" I have access to the CSS file, which I can change. I have access to the PHP files, i.e. shop.php, but it doesn't appear that the final link is generated locally. I'm showing the iframe this way:
<iframe src="http://nonprofit.org/shop/mj/shop.php"></iframe>
Is it possible to use jQuery or Javascript to find the links to mydomain.com with that one class and add a new window attribute to them? Or is there a better way? Thanks
Without some code I don't know the exact structure of your code, but I this could do the job. It requires jQuery to be in the iframe too.
$('iframe')[0].$('.av_buy_now').filter(function() {
return $(this).attr('href').indexOf('mydomain.com') > -1;
}).attr('target', '_blank');
You can change it if some how you can manage to execute this kind of code, changing class is little troublesome, of you got an id on it do something like this.
PAGE.html:
<button onclick="openinnewwin()">Get It</button>
<iframe src="test.html" id="ifrm"></iframe>
<script language="javascript">
function openinnewwin(){
ob=document.getElementById('ifrm');
if ( ob.contentDocument ) {
ob.contentDocument.getElementById('a').target="_blank";
}else if ( ob.contentWindow ){
ob.contentWindow.getElementById('a').target="_blank";
}
}
</script>

Hello
I've created a JavaScript script that can be pasted on someone's page to create an iFrame. I would like for the person to be able to paste the script where they would like the iFrame to appear.
However, I can't figure out how to append the DOM created iFrame to the location where the script has been pasted. It always appends it to the very bottom of the body.
How do I append in place?
Mm. You could do:
document.write("<div id='iframecontainer'></div>");
document.getElementById('iframecontainer').innerHTML = '...';
But that feels ugly/wrong in a lot of different levels. I am not aware of any other alternatives, though.
EDIT: Actually, a quick google search revealed this artlcle which discusses why document.write is ugly and a nice alternative for the particular pickle you're in: Give your script tag an ID!
<script id="iframeinserter" src=".."></script>
And then you can get a reference to the script tag and insert the iframe before it:
var newcontent = document.createElement('iframe');
var scr = document.getElementById('iframeinserter');
scr.parentNode.insertBefore(newcontent, scr);
Paulo's answer can also be done without the ID, by simply looking for the last <script> element. This must be the script block we're in, because JavaScript guarantees all content past the closing tag of the current script block has not yet been parsed(*):
var scripts= document.getElementsByTagName('script');
var script= scripts[scripts.length-1];
script.parentNode.insertBefore(d, script);
This can be put in an onload/ready function if you like, but if so the ‘var script’ must be calculated at include-time and not in the ready function (when that executes, more <script>s will have been parsed).
(*: except in the case of <script defer>.)
If the user can give an id of an element that will be where the iframe should be, then it would be possible to just use css to move the iframe to where it should be on the page.
