How to properly modify the alert function in javascript

Question

I want to check the contents of the alert before it "alerts".

I have this function:

function alert(msg) {

    // THIS WILL CHECK IF THE WORD FUNCTION IS EXISTING IN A STRING
    var searchFunction = jQuery.type(msg);

    if(searchFunction != 'function')
    {
        return;
    }
}

However, I don't know how to "alert" since I modified the alert function already.

Thanks in advance!

Why would you want to pass a string with the word "function" to this method and what would you do if that is the case? — Esko, Apr 11 '14 at 06:14

Before modifying the alert, do this:

var myAlert = alert;

Now you can do myAlert("Hi, I am a alert");
