opening the extension option page

[Paolo Casaschi]

If you open the extension options page using the chrome://extensions
page or the menu item in the page action / browser action, chrome has
a mechanism to remember if the options page is opened already, so it
just switches to the tab already open instead of opening a duplicate.

If I open the page with javascript, such as

chrome.tabs.create({url: "options.html"});

then chrome opens a new tab any time, creating duplicates every time.

Question: is there an API or something available to extensions to open
the options page with the same effect as chrome does?

Thanks.

You can do this (or something similar):

extviews = chrome.extension.getViews({"type": "tab"})

function focusTab(tab) {
// Focus the given tab
chrome.tabs.update(tab.id, {"selected": true});
}

for (var i=0; i++; i<=extviews.length) {
if (i == extviews.length) {
// Create new tab if past end of list and none open
chrome.tabs.create(
chrome.extension.getURL('/path/to/options.html')
);
} else if (extviews[i].location.href ==
chrome.extension.getURL('/path/to/options.html')) {
// Get the tab's object and focus the tab
extviews[i].chrome.tabs.getCurrent(focusTab);
break;
}
}

If you know options.html is the only page you'll ever have open in a
tab, you can skip the for loop and just check to see if there is at
least one item in the list.

Hi Paulo

I'm been wondering the same thing.

Currently I'm doing this:

function openOptions()
{
var id = chrome.i18n.getMessage("@@extension_id") + "/options.html";

chrome.tabs.getAllInWindow( undefined, function(tabs)
{
for( var i = 0, tab; tab = tabs[ i ]; i++)
{
if( tab.url && tab.url.indexOf( id ) != -1 )
{
chrome.tabs.update( tab.id, {selected: true} );
return;
}
}

chrome.tabs.create( {'url': chrome.extension.getURL( 'options.html' ) },
function( tab )
{
}
);
});
}

which seems to work, but it feels like it should be easier...

Maybe somebody can put me right 8-)

Cheers,
Nige

PS It's my first post - please be gentle!

Alan that works once you make sure your variable names are consistent, i.e. change two instances of "options" to "options_url".

Even better:

var options_url = chrome.extension.getURL('options.html');

chrome.tabs.query({

    url: options,

}, function(results) {

    if (results.length)

        chrome.tabs.update(results[0].id, {active:true});

    else

        chrome.tabs.create({url:options});

})

I think Google should minify our JavaScript after reviewing and then publish...
