Question

The iScroll documentation shows a typical iScroll setup like the one below.

var myScroll;
function loaded() {
    setTimeout(function () {
        myScroll = new iScroll('wrapper');
    }, 100);
}
window.addEventListener('load', loaded, false);

My question is how do I call the scroller? If I use:

var currentItem = 5;
myScroll.scrollToElement('.nav > li:nth-child('+currentItem+')', 300);

I get an error.

Uncaught TypeError: Cannot call method 'scrollToElement' of undefined 

Answer 1

I suppose you need to use the variable name you assigned the iScroll to:

myScroll.scrollToElement ...

and not

scroller.scrollTo ...

Update:

According to your latter tests, it obviously was a timing error. You proably called myScroll.scrollToElement before the timeout function was executed.
