javascript - How to execute when between heights using jquery

Question

I am wanting to alert someone but only when the scroll height is between a curtain height.

For instance.

When the person scrolls between 2000 pixels and 2500 pixels

I know how to do greater and smaller but how to do between?

var currentscroll = jQuery(this).scrollTop();

if(currentscroll > 2000){
alert('this');
}

Thanks

尝试这个：

var currentscroll = jQuery(this).scrollTop();

if((currentscroll > 2000) && (currentscroll < 2500)){
alert('this');
}
