Question

So say I have a function. I want it to return a value when an event is triggered, says when a button is clicked. In the function, I have var funcStorage=this; In the button, I have onclick="funcStorage.return("something");".

First, how do I make the function wait for the click asynchrously. Second, how do I trigger the return statement like this? Also, I am a very new user and this is my first question. How do I format code?

Answer 1

In your button:

onclick="return MyFunction('something')" 

your function:

function MyFunction(arg)
{
    //do stuff
    return true; //return false if you don't want the button action to happen
}
