780864 - Second dynamic iframe with same name loses listeners

Status: RESOLVED DUPLICATE of bug 170799

(Core :: DOM: Core & HTML, defect)

Description

[dimhold]

Attachment: Test case

User Agent: Mozilla/5.0 (Windows NT 6.1; rv:14.0) Gecko/20100101 Firefox/14.0.1
Build ID: 20120713134347

Steps to reproduce:

I dynamically create iframe on the button click:
     document.getElementById("iframeContainer").innerHTML = '<iframe name="iframeName" id="iframe" src="iframe.html"/>';

I add listener to the iframe's button (when iframe loaded):     frames["iframeName"].document.getElementById("iframeButton").addEventListener("click", function () {
               console.info("main: click");
     });

On the first iframe creation I see "main: click", but on the second creation - the click listener doesn't work.

Ugly workaround: create iframe with unique name:
     document.getElementById("iframeContainer").innerHTML = '<iframe name="iframeName_' + (new Date()).getTime() + '" id="iframe" src="iframe.html"/>';

Also I guess this case eats up memory.


I'm attaching a simplified test case.


Reproducible: Always

Steps to Reproduce:
0) Open main.html from attached archive.

1) Click the "Create iframe [innerHtml]" or "Create iframe [createElement]" button.
2) Click the "Click me" button
3) Look at console: iframe: click ; main: click - OK!!!

4) Click the "Create iframe [innerHtml]" or "Create iframe [createElement]" button AGAIN.
5) Click the "Click me" button AGAIN.
6) Look at console: iframe: click - One event listener? --> BUG!!!




Actual results:

1) listener does not invoked.
2) iframe 'load' event doesn't fire (I also added listener by setTimeout - doesn't work too)



Expected results:

1) The second dynamic iframe with same name should works as the first dynamic iframe.

It works if remove property by delete command, before adding iframe to dom tree.

+		delete frames[iframeName];
		document.getElementById("iframeContainer").innerHTML = iframeHtml;



+		delete frames[iframeName];
		document.getElementById("iframeContainer").appendChild(iframe);
