Question

Im trying to call functions with same signature.

Example: There are two functions with same name:

<script>
    var obj1,obj2,obj3,obj4,obj5;
    function OpenBox(obj1,obj2){
    // code
    }
    function OpenBox(obj1,obj2,obj3,obj4,obj5){
    // code
    }
</script>

When I calling function on click event of link

<a id='hlnk1' href='#' onclick='OpenBox(this,\"abhishek\"); return false;'> Open Box </a>

When I click on the above link it is calling function OpenBox(obj1,obj2,obj3,obj4,obj5){}

It should be call function OpenBox(obj1,obj2){} Instead.

What’s going wrong in functions?

Answer 1

mattn has the correct idea. Because javascript has no typing those functions are equivalent. What you could do is something like this:

function OpenBox_impl1(obj1,obj2){
    // code
}
function OpenBox_impl2(obj1,obj2,obj3,obj4,obj5){
    // code
}

function OpenBox(obj1, obj2, obj3, obj4, obj5) {
    if(arguments.length == 2)
        return OpenBox_impl1(obj1, obj2);
    else
        return OpenBox_impl2(obj1,obj2,obj3,obj4,obj5);
}
