I have a jQuery plugin that overrides link behavior, to allow Ajax loading of page content. Simple enough with a delegated event like $(document).on('click','a', function(){});.

but I only want it to apply to links that are not like these ones (Ajax loading is not applicable to them, so links like these need to behave normally):

target="_blank"      // New browser window
href="#..."          // Bookmark link (page is already loaded). 
href="afs://..."     // AFS file access. 
href="cid://..."     // Content identifiers for MIME body part.
href="file://..."    // Specifies the address of a file from the locally accessible drive.
href="ftp://..."     // Uses Internet File Transfer Protocol (FTP) to retrieve a file.
href="http://..."    // The most commonly used access method. 
href="https://..."   // Provide some level of security of transmission 
href="mailto://..."  // Opens an email program.
href="mid://..."     // The message identifier for email.
href="news://..."    // Usenet newsgroup.
href="x-exec://..."  // Executable program.
href="http://AnythingNotHere.com"  // External links

Sample code:

$(document).on('click', 'a:not([target="_blank"])', function(){
    var $this = $(this);
    if ('some additional check of href'){
        // Do ajax load and stop default behaviour
        return false;
    }
    // allow link to work normally
});

Q:

Is there a way to easily detect all "local links" that would only navigate within the current website? excluding all the variations mentioned above.

Note: This is for an MVC 5 Razor website, so absolute site URLs are unlikely to occur.
