Answer 1

There is no way to function overloading in javascript. So, I recommend like the following by typeof() method instead of multiple function to fake overloading.

function multiTypeFunc(param)
{
    if(typeof param == 'string') {
        alert("I got a string type parameter!!");
     }else if(typeof param == 'number') {
        alert("I got a number type parameter!!");
     }else if(typeof param == 'boolean') {
        alert("I got a boolean type parameter!!");
     }else if(typeof param == 'object') {
        alert("I got a object type parameter!!");
     }else{
        alert("error : the parameter is undefined or null!!");
     }
}

Good luck!
