How to get the length of the arguments

ziscloud

Hi all,

In the javascript, we can get the arguments's length using following code:

function myFunction()
{
alert(myFunction.arguments.length);
}

But in sahi, I tried this way:

function myTest() {
_alert(myTest.arguments.length);
}

myTest(1,2,3);

I got the type error: myTest is undefined.

I tried this:

function myTest() {
_alert(arguments.length);
}

myTest(1,2,3);

Sahi just give zero not three.

Anybody can help me!

Thanks a lot!

Hi,

You can try it as,

function myTest() {
var $res = arguments.length;
_alert($res);
}
myTest(1,2,3);

and its important that you have to prefix a $ sign before variables which are passed to sahi functions because otherwise it will consider "res" as a string and not as a variable.

Small correction.

When you write
_alert(res);
Sahi will search for the variable res on the browser (and will not get it)

When you write
_alert($res);
Sahi will evaluate $res on the proxy and pass it to _alert on the browser.
