Javascript regex URL matching

Question

I have this so far:

chrome.tabs.getSelected(null, function(tab) 
{
    var title = tab.title;
    var btn = '<a href="' + tab.url + '" onclick="save(\'' + title + '\');"> ' + title + '</a>';
        
    if(tab.url.match('/http:\/\/www.example.com\/version.php/i')) 
    {
        document.getElementById('link').innerHTML = '<p>' + btn + '</p>';
    }
});

Basically it should match the domain within this:

http://www.example.com/version.php?*

Anything that matches that even when it includes something like version.php?ver=1, etc

When I used the code above of mine, it doesn't display anything, but when I remove the if statement, it's fine but it shows on other pages which it shouldn't only on the matched URL.

EDIT:

if(tab.url.match(/http:\/\/www.example.com\/version.php/i)) 
{
    document.getElementById('link').innerHTML = '<p>' + btn + '</p>';
}

Doesn't even work somehow...

Answer 1

Try this:

if(tab.url.match(/http\:\/\/www\.example\.com\/version\.php/i)) 
{
    //...
}
