Error on using alert in Javascript (Property 'alert' of object is not a function)

Question

I am just trying to use alert and put a string variable inside the alert and get an error:

Uncaught TypeError: Property \'alert\' of object [Object Window] i         


        

Answer 1

Adding to Chris's answer... I had mistakenly overrode alert in my own function!

    //Don't do this:
    function alertOrConsole(node, alert){
        if(alert){
            alert(node);
        }else{
            console.log(node);
        }
    }

   //----------------------------
   //Fixed:
    function alertOrConsole(node, flag){
        if(flag){
            alert(node);
        }else{
            console.log(node);
        }
    }
