NAME

JavaScript::Writer::Var - javascript variable can tie with perl's

DESCRIPTION

This modules does an old trick with tie, so you can have a perl variable in your code, but when you do assignments, it'll effect the variable in the javascript output.

You should'nt use this module directly, please read the description of var method in JavaScript::Writer moudle. That's the document you only need to read.

METHODS

new(\$your_var, $params)

Constructor, this does the tie for you. The first arg needs to be a scalar reference. You'll need to create that variable in your scope, calling this method will call tie your variable.

TIESCALAR()

STORE()

FETCH()

As you can see, these three methods are required to full-fill the tie interface. Whenever you do an variable assignement, it'll be written as a javascript assignment too. Only the value are dumped with JSON::Syck.
