I have an iframe on a page, coming from a 3rd party (an ad). I'd like to fire a click event when that iframe is clicked in (to record some in-house stats). Something like:
$('#iframe_id').click(function() {
//run function that records clicks
});
..based on HTML of:
<iframe id="iframe_id" src="http://something.com"></iframe>
I can't seem to get any variation of this to work. Thoughts?
There's no 'onclick' event for an iframe, but you can try to catch the click event of the document in the iframe:
document.getElementById("iframe_id").contentWindow.document.body.onclick =
function() {
alert("iframe clicked");
}
EDIT
Though this doesn't solve your cross site problem, FYI jQuery has been updated to play well with iFrames:
$('#iframe_id').on('click', function(event) { });
Update 1/2015
The link to the iframe explanation has been removed as it's no longer available.
Note
The code above will not work if the iframe is from different domain than the host page. You can still try to use hacks mentioned in comments.
I was trying to find a better answer that was more standalone, so I started to think about how JQuery does events and custom events. Since click (from JQuery) is just any event, I thought that all I had to do was trigger the event given that the iframe's content has been clicked on. Thus, this was my solution
$(document).ready(function () {
$("iframe").each(function () {
//Using closures to capture each one
var iframe = $(this);
iframe.on("load", function () { //Make sure it is fully loaded
iframe.contents().click(function (event) {
iframe.trigger("click");
});
});
iframe.click(function () {
//Handle what you need it to do
});
});
});
Try using this : iframeTracker jQuery Plugin, like that :
jQuery(document).ready(function($){
$('.iframe_wrap iframe').iframeTracker({
blurCallback: function(){
// Do something when iframe is clicked (like firing an XHR request)
}
});
});
It works only if the frame contains page from the same domain (does
not violate same-origin policy)
See this:
var iframe = $('#your_iframe').contents();
iframe.find('your_clicable_item').click(function(event){
console.log('work fine');
});
You could simulate a focus/click event by having something like the following.
(adapted from $(window).blur event affecting Iframe)
$(window).blur(function () {
// check focus
if ($('iframe').is(':focus')) {
console.log("iframe focused");
$(document.activeElement).trigger("focus");// Could trigger click event instead
}
else {
console.log("iframe unfocused");
}
});
//Test
$('#iframe_id').on('focus', function(e){
console.log(e);
console.log("hello im focused");
})
None of the suggested answers worked for me. I solved a similar case the following way:
<iframe id="iframe_id" src="http://something.com" allowtrancparency="yes" frameborder="o"></iframe>
The css (of course exact positioning should change according to the app requirements):
#iframe-wrapper, iframe#iframe_id {
width: 162px;
border: none;
height: 21px;
position: absolute;
top: 3px;
left: 398px;
}
#alerts-wrapper {
z-index: 1000;
}
Of course now you can catch any event on the iframe-wrapper.
You can use this code to bind click an element which is in iframe.
jQuery('.class_in_iframe',jQuery('[id="id_of_iframe"]')[0].contentWindow.document.body).on('click',function(){
console.log("triggered !!")
});
This will allow you to target a specfic element in the iframe such as button or text fields or practically anything as on method allows you to put selector as an argument
$(window).load(function(){
$("#ifameid").contents().on('click' , 'form input' , function(){
console.log(this);
});
});
Maybe somewhat old but this could probably be useful for people trying to deal with same-domain-policy.
let isOverIframe = null;
$('iframe').hover(function() {
isOverIframe = true;
}, function() {
isOverIframe = false;
});
$(window).on('blur', function() {
if(!isOverIframe)
return;
// ...
});
Based on https://gist.github.com/jaydson/1780598
You may run into some timing issues depending on when you bind the click event but it will bind the event to the correct window/document. You would probably get better results actually binding to the iframe window though. You could do that like this:
var iframeWin = $('iframe')[0].contentWindow;
iframeWin.name = 'iframe';
$(iframeWin).bind('click', function(event) {
//Do something
alert( this.name + ' is now loaded' );
});
This may be interesting for ppl using Primefaces (which uses CLEditor):
document.getElementById('form:somecontainer:editor')
.getElementsByTagName('iframe')[0].contentWindow
.document.onclick = function(){//do something}
I basically just took the answer from Travelling Tech Guy and changed the selection a bit .. ;)
Solution that work for me :
var editorInstance = CKEDITOR.instances[this.editorId];
editorInstance.on('focus', function(e) {
console.log("tadaaa");
});
You can solve it very easily, just wrap that iframe in wrapper, and track clicks on it.
Like this:
<div id="iframe_id_wrapper">
<iframe id="iframe_id" src="http://something.com"></iframe>
</div>
And disable pointer events on iframe itself.
#iframe_id { pointer-events: none; }
After this changes your code will work like expected.
$('#iframe_id_wrapper').click(function() {
//run function that records clicks
});

I want to get the .click of the image on Froala Editor to create a customize function, for that I want to get the image I have selected in the Froala Editor.
I have Tried a couple of methods for this.
1.froalaEditor.click function:
$('#froala_editor').on('froalaEditor.click', function(e, editor, clickEvent) {
console.log(clickEvent.toElement);
});
2.Custome jQuery function
$.extend({
IFRAME: function (s) {
var $t = $('.campaign-create-sec').find('iframe');
if (typeof s !== 'undefined') {
return $t.contents().find(s);
}
return $t;
}
});
$('#froala_editor').on('froalaEditor.initialized', function (e, editor) {
$.IFRAME('body').on('click', function (e) {
console.log(e.target);
});
});
In the above, both cases I am getting all the other elements other than <img> and <video> of what I tested, so Is there any other way for me to get the click even for an image in Froala Editor.
A fiddle for you to check, any help will be appreciated.
You can try this.
var monitor = setInterval(function(){
var iframe_found = $('iframe').length;
console.log('iframe_found '+iframe_found);
if (iframe_found) {
clearInterval(monitor);
$('iframe').contents().find("img").click(function(){
$(this).css('border','2px solid #090');
console.log('got that!');
});
}
}, 100);
Here is the working fiddle.
setInterval() : For checking iframe presence after page load. iframe may only load after the page data is loaded & in your case its from a editor plugin, may take some time surly to load.
$('iframe').length; : Confirms presence of iframe.
clearInterval() : For destroying the setInterval(), so avoids multiple checking again for iframe.
And, at last we are finding required img tag.
Try... Have a nice day.
I have a script that closes an iframe after a click it.
I need that when you click on the link inside the iframe has delay 15 seconds to load a page within the iframe and after 15 seconds the iframe automatically closes.
$(window).on('blur',function(e) {
if($(this).data('mouseIn') != 'yes')return;
$('iframe').filter(function(){
return $(this).data('mouseIn') == 'yes';
}).trigger('iframeclick');
});
$(window).mouseenter(function(){
$(this).data('mouseIn', 'yes');
}).mouseleave(function(){
$(this).data('mouseIn', 'no');
});
$('iframe').mouseenter(function(){
$(this).data('mouseIn', 'yes');
$(window).data('mouseIn', 'yes');
}).mouseleave(function(){
$(this).data('mouseIn', null);
});
$('iframe').on('iframeclick', function(){
$(this).hide()
});
$('<input type="text" style="position:absolute;opacity:0;height:0px;width:0px;"/>').appendTo(document.body).blur(function(){
$(window).trigger('blur');
}).focus();
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<iframe style="width:400px;
height:250px;" src="//example.com"></iframe>
If you want to stick to Jquery you can use .delay()
http://api.jquery.com/delay/
To wait 15 seconds before the iframe close, you should do this :
$('iframe').on('iframeclick', function(){
$(this).delay(15000).hide();
}
In a simple way, you put a delay of 15s before the "hide" action
You are looking for the setTimeout() method. You can find how to use it here: http://www.w3schools.com/jsref/met_win_settimeout.asp.
In your case would be something like (this can be optimized, take out global var etc.):
globalVar = null;
function closeIframe() {
globalVar.hide();
}
$('iframe').on('iframeclick', function(){
globalVar = $(this);
setTimeout("closeIframe()", 15000);
});
Use good old setTimeout:
var timeoutValue = 15000; /*ms*/
setTimeout(function(){...}, timeoutValue);
which in you case could look like:
var close = function(element){element.hide();};
$('iframe').on('iframeclick', function(){
var timeoutValue = 15000;
var context = $(this);
setTimeout(function(){close(context)}, timeoutValue);
});
Binding event listeners to elements inside the iframe will only work if both the parent site and the iframe are on the same domain. If the contents of the iframe is on a different domain, you won't be able to perform this as it is classed as "click-jacking", which is a big security threat. See http://en.wikipedia.org/wiki/Same-origin_policy
If the iframe is on the same domain then you can add the event listener inside the iframe and then call the parent to notify the event.
You can also grab the contents and find the element you want to bind the event handler on.
$("iframe#name").contents().find(".link").on("click", function() {
$("iframe#name").delay(15000).hide();
});

I used sleep () function and solved my problem!
I've found a plugin called screenfull.js and I'm wondering if it's possible to automatically open the page in fullscreen without clicking on a button.
This is an example of code for making the page fullscreen :
document.getElementById('#button').addEventListener('click', function() {
if ( screenfull ) {
screenfull.request();
} else {
// Ignore or do something else
}
});
Using their demo, you could just run the request on window load:
e.g.
window.onload = function() {
screenfull.request( $('#container')[0] );
};
[edit]
You could also run this with jQuery document ready...
E.g.
$(document).ready(function() {
screenfull.request( $('#container')[0] );
});
No, that is not possible. The requestFullScrenn() must be triggered by a direct user action (like a click) for security considerations. It's just the same as with popups.
Read https://wiki.mozilla.org/Security/Reviews/Firefox10/CodeEditor/FullScreenAPI and maybe https://wiki.mozilla.org/Gecko:FullScreenAPI for reference.
I use a trick...
I listen for any click on the body to activate.
Eg:
$('body').on('click', '*', function() {
screenfull.request();
});
N.B.: It does not track buttons (e.t.c) that already have event handlers...
I want to separate these functions. They should both work separately on click events:
FIRST FUNCTION
$("ul.nav li").delegate("a", "click", function() {
window.location.hash = $(this).attr("href");
return false;
});
$(window).bind('hashchange', function(){
newHash = window.location.hash.substring(1);
if (newHash) {
ACTION A
});
$(window).trigger('hashchange');
});
SECOND FUNCTION
$("ul.subnav li").delegate("a", "click", function() {
window.location.hash = $(this).attr("href");
return false;
});
$(window).bind('hashchange', function(){
newHash = window.location.hash.substring(1);
if (newHash) {
ACTION B
});
$(window).trigger('hashchange');
});
This is what happend in ACTION A:
$mainContent
.find(".maincontent")
.fadeOut(200, function() {
$mainContent.hide().load(newHash + " .maincontent", function() {
$mainContent.fadeIn(200, function() {
$pageWrap.animate({
height: baseHeight + $mainContent.height() + "px"
});
});
$(".nav a").removeClass("active");
$(".nav a[href="+newHash+"]").addClass("active");
});
});
The Problem is that if I click the Link of the Second function always the the first function fires.
Details of what I'm trying to do:
First, I build my site on .php to serve poeple without JavaScript. Now I want to load the "maincontent" dynamically. So I found this script I'm using:
http://css-tricks.com/6336-dynamic-page-replacing-content/
It does do a great job if you only want to load "maincontents".
But my site has sub-navigation on some pages where I want to load the sub-content. In .php these sites use includes. So I get my content by: href="page2.php?page=sub1"
So, when I click on the sub-links now they load also dynamically but the script also on the whole maincontent loading area. So it doesn't really load content by .load() but the sub-content of the includes do appear.
So what I thought was just to separate this function. The first to simply load the maincontents and a second one for the sub-navigation to refresh only the sub-content area. I don't even understand how this script loads the include content dynamically since the link is the straight page2.php?page=sub1 link. All dynamic loaded content usually looks like "#index", without the ending ".php".
Some quick history:
I'm trying to get the best page structure. Deliver .php for non JavaScript user and then put some dynamic loading stuff over it. Always with the goal to keep the browser navigation and the browser links (for sharing) for each page in tact.
I'm not an jQuery expert. All I have learned so far was by trial and error and some logical thinking. But of course, I have a lack of fundamental knowledge in JavaScript.
So my "logical" question:
How can I tell the "nav" links to perform only their "$(window).bind"-Event and to tell the "subnav" links only to perfom their "$(window).bin"-event.
Is this the right thinking?
Since I've already been trying to solve it for nearly the last 18h, I'll appreciate any kind of help.
Thank you.
IMPORTANT:
With the first function I not just only load the maincontent but also I'm changing a div on the page with every link. So for any solution that might want to put it together in one, it won't work, cause they should do different things on different areas on the page. That's why I really need to call on the window.bind with each nav/subnav click.
Can anyone show me how?
Melros,
In your second function, you are binding to the event hashchange2, which is incorrect. Instead, you STILL want to bind to hashchange. Instead of:
$(window).bind('hashchange2', function() {
...
});
Try:
$(window).bind('hashchange', function() {
...
});
If you want to namespace your event subscriptions, you can suffix the ending of the event you are binding to with a period (.) and then the namespace:
$("#test").bind("click.namespace1", function() { });
$("#test").bind("click.namespace2", function() { });
Ok, it seems that you want to execute action A when a link inside .nav is clicked, and action B when a link inside .subnav is clicked.
You can just put these actions inside the event handlers. Furthermor, if .subnav is nested inside .nav, you have to restrict your selector:
// consider only direct children
$("ul.nav > li").delegate("a", "click", function() {
var href = $(this).attr("href");
if(window.location.hash !== href) {
Action A
window.location.hash = $(this).attr("href");
}
return false;
});
// consider only direct children
$("ul.subnav > li").delegate("a", "click", function() {
var href = $(this).attr("href");
if(window.location.hash !== href) {
Action B
window.location.hash = $(this).attr("href");
}
return false;
});
I don't think listening to the hashchange event will help you here, as this event is triggered in both cases and you cannot know which element was responsible (you probably can somehow, but why make it overly complicated?).
Here's by the way the solution I came to:
After understanding that the haschange-event doesn't have to do anything with it (as long as you don't want to make the subcontent bookmarkable too) I just added a new load function for the subcontent:
$(function(){
$("ul.linkbox li a").live('click', function (e) {
newLink = $(this).attr("href");
e.preventDefault();
$(".textbox").find(".subcontent").fadeTo(200,0, function() {
$(".textbox").load(newLink + " .subcontent" , function() {
$(".subcontent").fadeTo(200,1, function() {
});
});
$("#wrapper").css("height","auto");
$("ul.linkbox li a").removeClass("activesub");
$("ul.linkbox li a[href='"+newLink+"']").addClass("activesub");
});
});
});
Problem:
You have a regular set of URL links in a HTML page e.g.:
Foo Bar
You want to create a JavaScript function such that when any HTML links are clicked, instead of the client's browser navigating to that new URL "/foo/bar" a JavaScript function is executed instead (e.g. this may for example make an Ajaxian call and load the HTML data without the need to reload the page).
However if the JavaScript is disabled OR a spider crawls the site, the UTL links are maintained gracefully.
Is this possible? Does it already exist? What's the usual approach?
EDIT 1:
These are some great answers!
Just a follow on question:
If the user clicks on the back button OR forward button, this would naturally break (as in it would go back to the last physical page it was on as opposed to one that was loaded).
Is there any way (cross browser) to maintain the back/forward buttons?
(e.g create an array of links clicked and over ride the browser buttons and use the array to navigate)?
<script type="text/javascript">
function your_function() {
alert('clicked!');
}
</script>
<a onclick="your_function();" href="/foo/bar">Foo Bar</a>
If Javascript is off, the link behaves normally.
In this case, unless your_function() does not return false, the link will be followed when clicked as well.
To prevent this, either make your_function() return false, or add return false; just after the function call in your onclick attribute:
<script type="text/javascript">
function your_function() {
alert('clicked!');
return false;
}
</script>
<a onclick="your_function();" href="/foo/bar">Foo Bar</a>
Or:
<script type="text/javascript">
function your_function() {
alert('clicked!');
}
</script>
<a onclick="your_function(); return false;" href="/foo/bar">Foo Bar</a>
Using element.addEventListener()
With default anchor behaviour following click:
<script type="text/javascript">
document.addEventListener("load", function() {
document.getElementById("your_link").addEventListener("click", function() {
alert('clicked');
}, true);
}, true);
</script>
<a id="your_link" href="/foo/bar">Foo Bar</a>
Without:
<script type="text/javascript">
document.addEventListener("load", function() {
document.getElementById("your_link").addEventListener("click", function(event) {
event.preventDefault();
alert('clicked');
}, true);
}, false);
</script>
<a id="your_link" href="/foo/bar">Foo Bar</a>
Given current HTML and W3C APIs, I would go for:
<script src="linkify.js"> </script>
in the markup, with linkify.js containing something like:
window.onload= function() {
document.addEventListener('click', function(ev) {
ev.preventDefault();
var el = ev.target;
if (el.tagName === 'A') {
// do stuff with el.href
}
}, false);
};
See e.g. http://jsfiddle.net/alnitak/nrC7G/, or http://jsfiddle.net/alnitak/6necb/ for a version which doesn't use window.onload.
Note that this code uses a single listener function registered on the document object, which will act on every <A> tag on the page that doesn't trap clicks for itself.
Use an onclick attribute:
click?
The return false prevents the default behaviour, in the absence of JavaScript, however, the link will be followed.
function do_whatever (e)
{
e.preventDefault ();
// do whatever you want with e.target
}
var links = document.getElementsByTagName ("a");
for (var i=0; i<links.length; ++i)
links[i].addEventListener ('click', do_whatever);
http://jsfiddle.net/bTuN7/
All done inside script and it won't 'hurt' if JavaScript doesn't work.
If you think about AJAX, then you have to know, that googlebot tries to parse it. http://www.youtube.com/watch?v=9qGGBYd51Ts
You can code like:
$('a').click(function() {
doSomethingWithURL($(this).attr('href'));
return false;
});
JavaScript is not executed in case it's disabled or if it's some web crawler, so from my point of view this is preferable.
There's quite a few methods out there such as this:
http://www.malbecmedia.com/blog/development/coding-a-ajax-site-that-degrades-gracefully-with-jquery/
Remember, though, that by virtue of a well setup server and caching you're not going to gain yourself much performance with an Ajax Load.
