How to remove a second hash added by the user?

I am using a lot of hashes in my URL for displaying messages and stuff, but I have a problem. It is fine when you click on a conversation to read it:

But, look what happens when the user attaches another hash to the end: (the subject disappears because the JavaScript gets confused)

How can I remove that second hash if there is one? I did this in Gmail before and it automatically removed them. So, how can I do this with my system? Here's my hash code:

if (window.location.hash) {
    var messageID = window.location.hash.replace('#!/message/', '');
    var msgSubject = $('#subject_' + messageID).text();
    //the below code checks if conversation exists
    $.get('tools.php?type=id_check&id=' + messageID, function(data) {
        if (data == 'true') {
            setTimeout(function() {
                readMessage(messageID, msgSubject);
            }, 200);
        }
        else {
            alertBox('The requested conversation does not exist.', 2500);
            window.location = '#';
        }
    });
}

Thanks in advance!

You can try

var matches = window.location.hash.match(/#!\/message\/(\d+)/);
if (matches) {
    var messageId = matches[1];
    // ...
}

This will capture a series of only digits after #!/message/. If the hash contains #!/message/123, then matches will be an array

['#!/message/123', '123']

and so matches[1] will contain the message id. If there is anything before or after it in the hash, it will be ignored. If there are no matches, matches will be null.
