arguments relay

pierre.voisin · February 20th, 2008, 05:34 PM

Hi!

    I'd like to know if arguments relay is possible. For example, I have the following function:

    function abc() {
        console.log(arguments);
    }

    and I would like have the following function like:

    function xyz() {
        abc(%[something, arguments]%);
    }

    In other words, I want to relay the same arguments, with no consideration for their count, and add an other one with them.

    Precision: I don't want to do Â«abc(something, arguments)Â» since the parameters to abc will be only two, the second being an array... :)

    Any idea? Is it clear? ^^'

    Thanks,

Pierre

OK guys, I found it... I just have to call the Â«applyÂ» method of my function with the new collection of parameters. :)

Code:

function abc(a, b, c, d, e) {
    console.log(a, b, c, d, e);
}

function xyz() {
    var a = $A(arguments);
    a.push(4);
    abc.apply(null, a);
}

xyz(1,2,3);
