Check if tab exists and make it active; otherwise create it

I'm attempting to see if the tab 'http://google.com' exists. If it does then I want to make it the active page. Otherwise, the tab 'http://google.com' doesn't exist, and I want to create it.

backround.js

chrome.runtime.onMessage.addListener(function(response, sender, sendResponse){
    chrome.tabs.create({'url': 'http://google.com'}, function(tab) {
        alert('Tab Created ' + tab.id);
        var oms = tab.id;
        chrome.tabs.update(oms, {url:"http://en.wikipedia.org"});
    });
});

This creates the webpage, gets the tabid and sets the tabid as a variable.

Your current attempt seems to be trying to create a tab with Google, and then navigate it to Wikipedia. This doesn’t agree with your initial paragraph. Instead, I think you want something similar to the following:

chrome.runtime.onMessage.addListener(function(response, sender, sendResponse){
    chrome.tabs.query({'url': 'http://google.com'}, function(tabs) {
        if ( tabs.length > 0 ) {
            chrome.tabs.update(tabs[0].id,{'active':true});
        } else {
            chrome.tabs.create({'url':'http://google.com'});
        }
    });
});

Note that this won’t find http://www.google.com, or http://google.com/otherstuff. You’ll probably want to use a match pattern.

You commented having trouble with updating the tab to be selected. The documentation says that selected is deprecated in favor of highlighted. This also hints what else may have happened: a highlighted tab is not necessarily active (specifically, you can have several tabs highlighted).
