Non-deprecated arguments

[Robert]

Hi,

Currently I am using
argument.callee.caller.arguments
to get the arguments of the caller function, but Firefox complains that
arguments (of Function) is deprecated.

Is there a way to get the arguments of the calling function in a
non-deprecated way?

I use this to do type-safe validation of the parameters by calling a
special validate function at the beginning of some javascript functions
and it really helped me. And now I just noticed it gave deprecated
warnings in my Firefox in strict javascript mode.
Of course I can pass the local arguments to the validate function, but I
want to keep each call to validate as easy to use as possible.

Thanks for any comments.

Robert.

I posted all the code that is relevant to my question

argument.callee.caller.arguments

Interesting signature.

I am no expert on this, but you could try emulating the arguments
property of Function:-

function f1(a)
{
arguments.callee.arguments=arguments;
f2();
}

function f2()
{
alert(arguments.callee.caller.arguments[0]);
}

Learn to read and no code is needed for that question.

Talking about one's self is not a sign of intelligence.

But doesn't tell you that the - caller - property is a JavaScript(tm)
feature, non-standardised and certainly not cross-browser?

No, a function's arguments are only exposed inside the function by ECMA
262, and there is no - caller - property of either the function or its
arguments.

Switch strict warnings off. There are not suitable for general browser
scripting and some are irrational and/or factually incorrect.

No, a function's arguments are only exposed inside the function by ECMA
262, and there is no - caller - property of either the function or its
arguments.

Whether or not ECMA says it should be exposed or not is irrelevant. If
Mozilla based browsers expose it, then it exposes it. If IE exposes it,
then it exposes it. If they don't, then they don't. And it has nothing
to do with ECMA.

That's right. It does not tell me this.

No,

Well that's too bad. I don't mind that some things get deprecated, but
why deprecate something without any means to achieve the same
functionality in another way....

There is nothing stopping you passing the - arguments - of one function
as an argument to another. So where you call a function that then
attempts to access it's callers arguments you can instead pass those
arguments to the function you call.

They are called the blessing of standardization.
And do not even dare say or mildly argue they could be less than
absolutely perfect, welcome, magnificent, and brilliant! :-)
