call function from button and inside function

Question

I have a function updateScreen to update text fields. I want to call the function from inside another buttons function.
 
function updateScreen() {
            (updates numerous text fields)
};
 
btnOne.addEventListener("click",  updateOne.bind(this));
function updateOne() {
           (changes variables);
           updateScreen()
}

Hi.

If your code lives in different instances, one approach would be to make the updateScreen function a method of the main timeline. Like this:

// CODE IN THE MAIN TIMELINE
this.updateScreen = function()
{
	// (updates numerous text fields)
};


// CODE SOMEWHERE ELSE
btnOne.addEventListener("click", updateOne.bind(this));

function updateOne()
{
	// (changes variables);
	// exportRoot is a global variable automatically created in the
	// publishing process that stores a reference to the main timeline
	exportRoot.updateScreen();
}

I hope this helps.

Regards,

JC
