Javascript for handeling hover effects, sorry I am not very good at writing Javascript.

    $('#main-content #slider-home #top-row ul li:nth-child(1)').hover(handlerIn1, handlerOut1);
$('#main-content #slider-home #top-row ul li:nth-child(2)').hover(handlerIn2, handlerOut2);
    $('#main-content #slider-home #top-row ul li:nth-child(3)').hover(handlerIn3, handlerOut3);
// ... 


function handlerIn1(evt){
    $('#main-content #slider-home #top-row ul li:nth-child(1) span').css({'display':'inline'});
    $('#main-img .active').removeClass("active");
    $('#main-img #group-1').addClass("active").css({
        'opacity':'0'}).animate({opacity:'1'}, 500);
    $('#main-content #slider-home #top-row ul li:nth-child(1)').addClass("ahover");
}   
function handlerOut1(evt){
        $('#main-content #slider-home #top-row ul li:nth-child(1) span').css({'display':'none'});
}   

function handlerIn2(evt){
    $('#main-content #slider-home #top-row ul li:nth-child(2) span').css({'display':'inline'});
    $('#main-img .active').removeClass("active");
    $('#main-img #group-2').addClass("active").css({
        'opacity':'0'}).animate({opacity:'1'}, 500);
}   
function handlerOut2(evt){
    $('#main-content #slider-home #top-row ul li:nth-child(2) span').css({'display':'none'});
}   

function handlerIn3(evt){
    $('#main-content #slider-home #top-row ul li:nth-child(3) span').css({'display':'inline'});
    $('#main-img .active').removeClass("active");
    $('#main-img #group-3').addClass("active").css({
        'opacity':'0'}).animate({opacity:'1'}, 500);
}   
function handlerOut3(evt){
    $('#main-content #slider-home #top-row ul li:nth-child(3) span').css({'display':'none'});

Currently I have a solution where element changes its style on hover. Example: I hover over li element, javascript adds span of image, and changes css display attribute, then css makes hover element to be displayed in different color and style. But what I really need is for element to stay with the changed style after I hover off. And activate another change of style when one of the li elements is hovered on.

How can I do this?

Answer 1

use .mouseenter(), if you want to trigger only when the mouse enters the elements

$('#main-content #slider-home #top-row ul li:nth-child(1)').mouseenter(handlerIn1)

Answer 2

You have to remove the handlerOut1 in your hover method. So just do that :

$('#main-content #slider-home #top-row ul li').hover(handlerIn1());

And the handlerIn1 function :

function handlerIn1() {
    $(this).children('span').css({'display':'inline'});
    $('#main-img .active').removeClass("active");
    $('#main-img #group-1').addClass("active").css({'opacity':'0'}).animate({opacity:'1'}, 500);
    $(this).addClass("ahover");
}
