Scripting : I’ve noticed something weird in scripting. Can anyone Explain why and how this is happening?

[Dan Ebberts]

An easy way to keep from cluttering AE’s namespace with your function names is to make sure everything in enclosed in a single function with a unique name, like this:


function AndiraiMaji_01(){

// your script here

}
AndiraiMaji_01();

Hey Dan, in such scenario – could you suggest what is the best way to treat global variables? Because if there are some affected variables inside the function, they will stay local within that ‘custom’ function. \

Should it be done by building object of variables to be returned or is there a better way?

Thanks!

That depends on what you mean by global. When I want something to be accessible from anywhere within my script, I declare an object just inside my enclosing function, like this:


function de_NewScript(){

// globals

var G = new Object();
G.scriptName = "Dan's New Script";\

// functions

function myUtilityFunction(){
// function code here
}

// main code

}
de_NewScript();


But if I need something global that two scripts can use to communicate, I would generally attach it to the app (maybe not recommended, but it seems to work):

app.de_object = {};
app.de_object.script1Present = true;

Dan, that is exactly what I was asking – thank you a ton!
