How to add click event to a iframe with JQuery

问题:

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?

回答1:

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.

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)
        }
    });
});

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
        });
    });
});

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\');
});

None of the suggested answers worked for me. I solved a similar case the following way:

<a href=\"http://my-target-url.com\" id=\"iframe-wrapper\"></a>
<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 !!\")
});

回答7:

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\");
})

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 });
