Detect click event inside iframe
JavascriptJqueryHtmlIframeTinymceJavascript Problem Overview
I'm writing a plugin for TinyMCE and have a problem with detecting click events inside an iframe.
From my search I've come up with this:
Loading iframe:
<iframe src='resource/file.php?mode=tinymce' id='filecontainer'></iframe>
HTML inside iframe:
<input type=button id=choose_pics value='Choose'>
jQuery:
//Detect click
$("#filecontainer").contents().find("#choose_pic").click(function(){
//do something
});
Other posts I've seen usually have a problem with different domains (this hasn't). But, still, the event isn't detected.
Can something like this be done?

Solution 1 - Javascript
I solved it by doing like this:
$('#filecontainer').load(function(){
var iframe = $('#filecontainer').contents();
iframe.find("#choose_pics").click(function(){
alert("test");
});
});
Solution 2 - Javascript
I'm not sure, but you may be able to just use
$("#filecontainer #choose_pic").click(function() {
// do something here
});
Either that or you could just add a <script> tag into the iframe (if you have access to the code inside), and then use window.parent.DoSomething() in the frame, with the code
function DoSomething() {
// do something here
}
in the parent.
If none of those work, try window.postMessage. Here is some info on that.

I know this is old but the ID's don't match in your code one is choose_pic and one is choose_pics:
<input type=button id=choose_pics value='Choose'>
$("#filecontainer").contents().find("#choose_pic").click(function(){
//do something
});
Solution 4 - Javascript
$("#iframe-id").load( function() {
$("#iframe-id").contents().on("click", ".child-node", function() {
//do something
});
});

The tinymce API takes care of many events in the editors iframe. I strongly suggest to use them. Here is an example for the click handler
// Adds an observer to the onclick event using tinyMCE.init
tinyMCE.init({
...
setup : function(ed) {
ed.onClick.add(function(ed, e) {
console.debug('Iframe clicked:' + e.target);
});
}
});

Just posting in case it helps someone. For me, the following code worked perfect:
$(document).ready(function(){
$("#payment_status_div").hide();
var iframe = $('#FileFrame').contents();
iframe.find("#take_payment").click(function(){
$("#payment_status_div").show("slow");
});
});
Where 'FileFrame' is the iframe id and 'take_payment' is the button inside iframe. Since my form inside the iframe is posted to a different domain, when used load, I got an error message saying: >Blocked a frame with origin "https://www.example.com" from accessing a frame with origin "https://secure-test.worldpay.com";. Protocols, domains, and ports must match.

In my case there were two jQuery's, for the inner and outer HTML. I had four steps before I could attach inner events:
- wait for outer jQuery to be ready
- wait for iframe to load
- grab inner jQuery
- wait for inner jQuery to be ready
$(function() { // 1. wait for the outer jQuery to be ready, aka $(document).ready
$('iframe#filecontainer').on('load', function() { // 2. wait for the iframe to load
var $inner$ = $(this)[0].contentWindow.$; // 3. get hold of the inner jQuery
$inner$(function() { // 4. wait for the inner jQuery to be ready
$inner$.on('click', function () { // Now I can intercept inner events.
// do something
});
});
});
});
The trick is to use the inner jQuery to attach events. Notice how I'm getting the inner jQuery:
var $inner$ = $(this)[0].contentWindow.$;
I had to bust out of jQuery into the object model for it. The $('iframe').contents() approach in the other answers didn't work in my case because that stays with the outer jQuery. (And by the way returns contentDocument.)

In my case, I was trying to fire a custom event from the parent document, and receive it in the child iframe, so I had to do the following:
var event = new CustomEvent('marker-metrics', {
detail: // extra payload data here
});
var iframe = document.getElementsByTagName('iframe');
iframe[0].contentDocument.dispatchEvent(event)
and in the iframe document:
document.addEventListener('marker-metrics', (e) => {
console.log('@@@@@', e.detail);
});
Solution 10 - Javascript
try
$('#yourIframeid').on("load", function () {
$(this).contents().on("contextmenu, keydown, mousedown, mouseup, click", function (e) {
//do your thing
});
});
use $('#yourIframeid').on("load") if $('#yourIframeid').onload( does not work.
