javascript - How to condense this into a single function? -


i new js/jquery, cant figure out how keep code d.r.y, if possible @ don't know. using jquery on hover effect image. box1 being div , img_hover_effect being overlay on hover.

js: 

$('.box1').hover(function () {     $('.img_hover_effect').fadein(500); }, function () {     $('.img_hover_effect').fadeout(400); }); $('.box2').hover(function () {     $('.img_hover_effect_2').fadein(500); }, function () {     $('.img_hover_effect_2').fadeout(400); }); $('.box3').hover(function () {     $('.img_hover_effect_3').fadein(500); }, function () {     $('.img_hover_effect_3').fadeout(400); });

you can use loop that.

an anonymous function inside loop used prevent breakage jquery events, try:

for(var = 1; <= 3; i++){     (function(num){         $('.box' + num).hover(function() {             $('.img_hover_effect' + (num == 1 ? "" : num)).fadein(500)         }, function(){             $('.img_hover_effect' + (num == 1 ? "" : num)).fadeout(400)         })     })(i) }
