thx Phillip,
that is a very useful hint.
i used it and it works.
is there any place to read more about it, because I do not understand
why it is working.
Scroll: function(dir){
var that = this;
if(dir=="down"){
this.btnsScrollTimer = setInterval(function ()
{that.BtnsScroll("down")}, 20); //works
//this.btnsScrollTimer = setInterval(function ()
{this.BtnsScroll("down").bind(this)}, 20); //wrong
//this.btnsScrollTimer = setInterval(function ()
{this.BtnsScroll("down")}, 20).bind(this); //wrong
} else {
this.btnsScrollTimer = setInterval(function ()
{that.BtnsScroll("up")}, 20);
}
},
