Which image upload for Yii would you recommend?

Question

JavaScript

What image upload do you use and on which yii?

Answer 1

If you assign a value to tempScrollTop before comparing to currentScrollTop , then you replace the previous value in tempScrollTop with currentScrollTop and your subsequent checks fail because the variables are now equal.

Answer 2

Read more about if's to avoid such questions.
If the assignment (equating) of variables at the top:
You have them equal by default at any moment of the scroll, there is no entry into if.
As I understand it, you want to display "up" and down - "down" when scrolling up, on each scroll?
To do this, you need to save the previous position and compare with it (initially it should be at zero).

var tempScrollTop=0,
 currentScrollTop;
$(window).scroll(function(){
    currentScrollTop = $(window).scrollTop();
    if (tempScrollTop < currentScrollTop ){
        alert("Вниз");
    }
    else if (tempScrollTop > currentScrollTop ) {
        alert("Вверх");
    }
     tempScrollTop = currentScrollTop;
});
