Question

I need to send this to the capIn() and capOut() functions so that I can target the children divs of the correct .slide. How do I pass this to a function. this would be what is hovered.

$(".slide").hover(function(){capIn();capOut();});

Answer 1

Looking at the function names capIn and capOut it makes sense that they are 2 different behaviors. I believe you have 2 different behaviors on mouseenter and mouseleave events. hover method can take 2 methods, one for mouseenter and another for mouseleave. You can try this

$(".slide").hover(capIn, capOut);

You can use this inside capIn and capOut it will point to .slide element which you hovered on.

function capIn(){
   var $childrens = $(this).children();
}

function capOut(){
   var $childrens = $(this).children();
}
