javascript - Determining downward and upward scrolling -

-

i have sapui5 table , trying log in console if table being scrolled or down. can working if use regular div.

example here.

but can't seem work sapui5 table. have tried following:

var lastscroll = 0; $("#__xmlview0--players-vsb-sb").scroll(function () {     var st = $(this).scrolltop();     if (st > lastscroll) {         console.log("scrolling down");     } else {        console.log("scrolling up");     }     lastscroll = st; });

i'm getting id #__xmlview0--players-vsb-sb when inspect element on scrollbar. seems id should use. ideas of how work?

here jsbin.

if put scroll event inside settimout, starts working.

        settimeout(function(){             var lastscroll = 0;         $("#__xmlview0--players-vsb-sb").scroll(function () {                 var st = $(this).scrolltop();                 if (st > lastscroll) {                     console.log("scrolling down");                 } else {                     console.log("scrolling up");                 }                 lastscroll = st;             }); }, 700);

this indication ui library clearing out events on elements uses when initializes own events on them. remove risk of memory leaks. suggest not using timeout, , seeing stack more info: sapui5-which method call once view displayed everytime?
