Page Action addListener gives error.

**rajesh.poddar** · 08-10-2009, 09:48 PM

I am writing a simple page action extension that is displayed for every tab and simple writes something to the console upon executing. However, I get the following error in the javascript debugger - "Uncaught TypeError: Cannot call method 'addListener' of undefined". I can't figure out why this is happening.

My manifest.json is:

Code:

{
  "background_page": "enable.html",
  "name": "HUL Redirect Extension",
  "version": "1.0",
  "description": "Extension for redirecting through HUL Proxy",
  "page_actions": [ {
     "id": "hulredirect",
     "icons": ["RedirectIcon.png"],
     "name": "HUL Redirect"
  } ]
}

and my enable.html is:

Code:

<html>
<head>
    <script type="text/javascript">
        chrome.tabs.onUpdated.addListener(function(tabid) {
            chrome.tabs.get(tabid, function(currentTab) {
                    chrome.pageActions.enableForTab('hulredirect', {
                        tabId: currentTab.id,
                        url: currentTab.url,
                        title: "HUL Redirect",
                        iconId: 0
                    });
		 });
	  });

        chrome.pageActions["hulredirect"].addListener(function(pageaction) {
		  console.log("Test");
        });

    </script>
</head>
<body>
</body>
</html>

Any help would be greatly appreciated.

Thanks,
Rajesh

I'm also having a problem with page actions, difference is I don't even get an error. The page action shows up in the omnibox but when clicked nothing happens.

manifest.json

Code:

{
	"name": "Page Action Test",
	"version": "1.0",
	"description": "Testing Page Actions.",
	"background_page": "background.html",
	"page_actions": [{
		"id": "myaction",
		"name": "Page Action",
		"icons": ["favicon.ico"]
	}]
}

background.html

Code:

<script type='text/javascript'>
chrome.tabs.onUpdated.addListener(function(tabId, chprops) {
	chrome.tabs.getSelected(null, function(tab) {
		chrome.pageActions.enableForTab("myaction", {
			tabId: tab.id,
			url: tab.url,
			title: tab.url,
			iconId: 0
		});
	});
});
chrome.pageActions["myaction"].addListener(function(details) {
	var tabId = details.data.tabId;
	var tabUrl = details.data.tabUrl;
	chrome.tabs.get(tabId, function(tab) { // this or anything else I've tried isn't happening
		chrome.tabs.create({url:tabUrl,index:tab.index+1});
	});
});
</script>

The code is pretty much identical. I wonder why I'm not getting anything at all while you're getting an error. :/

I think he's right, when the "official" sample isn't working it's definitely broken somewhere.
