I’m not really good at JavaScript so I’m here asking.
Below is a sample code:
<html>
<head>
<script>
function test(one)
{
alert('surprise! first function with one parameter');
}
function test(one,two)
{
alert('expected: second function with two parameters');
}
</script>
</head>
<body onload="javascript:test('first')">
</body>
</html>
Questions:
I expected that that 'surprise! first function with one parameter' would be then alerted onload because I call the function with one parameter only. To my surprise it alerted in the second function.
- Can someone explain this to me why?
- and how can I make my way around it?
Javascript doesn’t support method overloading;
It just overwrites the function so the last one will get called every time.
A way around it is just to make 1 function and put some conditions in there to check if the variables are set.
