How do I make a firefox extension execute script on page open/load? [migrated]
- by Will Mc
Thanks in advance!
I am creating my first extension (A firefox extension). See below for full description of final product.
I need help starting off. I have looked and studied the HelloWorld.xpi example found on Mozilla's site so I am happy to edit that to learn. In the example, when you click a menu item it runs script to display an alert message.
My question is, how would I edit this extension to run the script on page load?
I am guessing I need to insert some code in the browserOverlay as it loads on page load so, here is the browserOverlay.xpi from the example I am editing to learn:
<?xml version="1.0"?>
<?xml-stylesheet type="text/css" href="chrome://global/skin/" ?>
<?xml-stylesheet type="text/css"
href="chrome://xulschoolhello/skin/browserOverlay.css" ?>
<!DOCTYPE overlay SYSTEM
"chrome://xulschoolhello/locale/browserOverlay.dtd">
<overlay id="xulschoolhello-browser-overlay"
xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul">
<script type="application/x-javascript"
src="chrome://xulschoolhello/content/browserOverlay.js" />
<stringbundleset id="stringbundleset">
<stringbundle id="xulschoolhello-string-bundle"
src="chrome://xulschoolhello/locale/browserOverlay.properties" />
</stringbundleset>
<menubar id="main-menubar">
<menu id="xulschoolhello-hello-menu" label="&xulschoolhello.hello.label;"
accesskey="&xulschoolhello.helloMenu.accesskey;" insertafter="helpMenu">
<menupopup>
<menuitem id="xulschoolhello-hello-menu-item"
label="&xulschoolhello.hello.label;"
accesskey="&xulschoolhello.helloItem.accesskey;"
oncommand="XULSchoolChrome.BrowserOverlay.sayHello(event);" />
</menupopup>
</menu>
</menubar>
<vbox id="appmenuSecondaryPane">
<menu id="xulschoolhello-hello-menu-2" label="&xulschoolhello.hello.label;"
accesskey="&xulschoolhello.helloMenu.accesskey;"
insertafter="appmenu_addons">
<menupopup>
<menuitem id="xulschoolhello-hello-menu-item-2"
label="&xulschoolhello.hello.label;"
accesskey="&xulschoolhello.helloItem.accesskey;"
oncommand="XULSchoolChrome.BrowserOverlay.sayHello(event);" />
</menupopup>
</menu>
</vbox>
</overlay>
I hope you can help me. I need to know what code I should use and where I should put it...
Here is the gist of my overall extension -
I am creating a click to call extension.
This extension will search any new page for a phone number whether just refreshed, new page, new tab etc...
Each phone number when clicked will open a new tab and direct user to a custom URL.
Thanks again!
