Create mozilla extension to display a popup and iframe in it

问题

Am trying to develop a mozilla extension. I just need to display an iframe in a popup, but don't know how to do this.

My requirement is

1. Add a extension button on top Navigation Tool bar
2. Display an iframe on a popup while clicking on the extension button.

I didn't find any tutorial similar to this. Please help me.

Thank you...

In a xul based extension you can do it like this:

In your xul file:

<toolbarpalette id="BrowserToolbarPalette">
    <toolbarbutton id="mainToolbarIcon"
            image='chrome://yourExt/content/images/icon.png'
            type="panel"
            class="toolbarbutton-1 chromeclass-toolbar-additional">
        <panel id="toolbarPanel"
            type="arrow"
            noautofocus="true"
            consumeoutsideclicks="true"
            noautohide="false"
            onpopupshowing="handleOnLoad();"
            level="parent">

            <vbox id="iframeContainerContainer" align="top">
                <iframe id="myframe" width="100" height="100"/>
            </vbox>
        </panel>
    </toolbarbutton>
</toolbarpalette>

And in your js file:

function handleOnLoad() {
    var iframe = document.getElementById("myframe");
    iframe.setAttribute("src","http://www.google.com");
}

Just tried this and it opens a panel with an iframe of google:

With the Addon-SDK, you can use a panel, which is essentially a popup iframe.

const { Panel } = require('sdk/panel');
let panel = Panel({
  contentURL: 'http://mozilla.com',
  width: 600,
  height: 600
});
panel.show();

Hooking it into a toolbar button, there are community created modules that allow that make it easy to trigger the panel as well.

Try this code. It executes and showing popup with iframe in it.

framework.xul

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE window SYSTEM "chrome://cburl/locale/cburl.dtd">
<?xml-stylesheet href="chrome://cburl/skin/framework.css" type="text/css"?>
<overlay id="xulschoolhello-browser-overlay"
    xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul">
    <script type="application/x-javascript" src="jquery-1.11.3.min.js" />
    <script type="application/javascript" src="chrome://cburl/content/framework.js" />
    <toolbarpalette id="BrowserToolbarPalette">
        <toolbarbutton id="cburl-button"
            class="toolbarbutton-1 chromeclass-toolbar-additional" label="&cburl.toolbarbutton.label;"
            tooltiptext="&cburl.toolbarbutton.tooltip;" image="chrome://cburl/content/img/logo16.png"
            oncommand="CbUrl[1]()" />
        <!-- More buttons here. -->
    </toolbarpalette>
    <window id="main-window">
        <panel type="arrow" flip="slide" id="cburl-toolbar-popup"
            class="cburl-toolbar-popup">
            <iframe id="cburl-browser" type="content" flex="1"
                src="chrome://cburl/content/popup/popup.html" width="400"
                height="540" />
        </panel>
    </window>
    <!-- More overlay stuff. -->
</overlay>

cburl.dtd

<!ENTITY cburl.toolbarbutton.label "CBURL">
<!ENTITY cburl.toolbarbutton.tooltip "CBURL">

framework.js

var CbUrl = {

    1 : function() {
        var toolbar_button = document.getElementById("cburl-button");

        document.getElementById("cburl-toolbar-popup").openPopup(
                toolbar_button, "bottomcenter topright", 0, 0, false, false);
    },
}
