default parameters values

Copy linkTweet thisAlerts:

Is there any posibility to put default parameters values in javascript?
in C you can use default parameters values like this:

myFunction(int a=2, int b=3)

if you don´t send any parameter to this function the value of a will be 2 and b will be 3, but if you pass any parameter to the function the variable will get the passed value.

Does anybody know if I can do this in javascript???

Thanks to everybody

@mrhooApr 10.2006 — [CODE]myFunction(a,b){
if(typeof(a)=='undefined')a=2;
if(typeof(b)=='undefined')b=3;
//
}[/CODE]

The above code allows you to pass null, 0, or '' as a parameter without replacing it. But if there is no value passed, the default is used.

If you always need a non zero value it is even simpler:


[CODE]function imp(wot, wch){
if(!wot) wot= 'html';
if(!wch) wch= '1.0';
var DI= (document)? document.implementation: false;
return (DI && DI.hasFeature)? DI.hasFeature(wot,wch): false;
}[/CODE]

Success!
