Creating global variables

Help
#1

Hey, is there any way you can make global variables in wick editor and/or js?

A variable declared outside a function, becomes GLOBAL .

A global variable has global scope : All scripts and functions on a web page can access it.

Example

var carName = "Volvo";
// code here can use carName
function myFunction() {
    // code here can also use carName
}

yes, but… that will make the variable global for the current script tab, not for the entire wick project… if you want it globally for the entire wick application, you should use:

project.carName = "Volvo";

(the caveat is that you must call it in that way everywhere, since carName is not the same as project.carName)

You can also attach a variable to the window, like this:

window.carName= "Volvo";

Then you can refer to it as just carName, or window.carName from any script.

using variable like
window.carName should make more easy to modify them outside wick canvas
Imagine a button in your html page (outside wick) that change that value and having wick do something afterwards
