jRails, jQuery, Hide (4 arguments)

Rails

Is this the right forum to post this to?

In jRails.js there is a call to
hide
in which hide takes four parameters.

Where is that hide defined?

To answer my own question … so for the next poor schmuck who doesn’t
know any Javascript …

Using firebug and the wonderful
http://jsbeautifier.org/
to unminimize javascripts so that you can actually use Firebug to track
through the code … one discovers that the hide is going to

hide: function () {
if (!arguments[0] || (arguments[0].constructor == Number ||
…
},

The answer is that hide:function can take an arbitrary number of
arguments. The value of the arguments is stored an array as a local
variable called “arguments”

If anyone can point me to the reference that shows what the
“hide:function” syntax is defined, I would be grateful.

Not really, but… :slight_smile:

I would think you’d be able to tell more from looking at the code of the
function in question than from any doc, but
http://api.jquery.com/hide/
would be the place. Assuming this is the jQuery ‘hide’ and not that of
prototype.js :slight_smile:
