Tricky delay on mouseover

Question

This is what I have currently:

$("#cart-summary").mouseenter(function () {
    $('.flycart').delay(500).slideDown('fast');
});
$(".flycart").mouseleave(function () {
    $('.flycart').delay(500).slideUp('fast');
}).find('a.close').click(function(){
   $(this).parents('.flycart').hide();
});

What it does is:

If mouseover #cart-summary -> open flycart after 500ms

if mouseout .flycart -> close flycart after 500ms

What I need is:

If mouseover #cart-summary for ATLEAST 500ms -> open flycart

if mouseout .flycart for ATLEAST 500ms -> close flycart

Edited to Add: I also use hoverIntent, if that can be used here?

Many thanks!

Answer 1

You can use the hoverIntent plugin as follows:

var config = {    
     sensitivity: 3, // number = sensitivity threshold (must be 1 or higher)    
     interval: 500, // number = milliseconds for onMouseOver polling interval    
     timeout: 500, // number = milliseconds delay before onMouseOut    
};

$(".flycart").hoverIntent(function () {
        $('.flycart').slideDown('fast');
}, function() {
        $('.flycart').slideUp('fast');
}).find('a.close').click(function(){
   $(this).parents('.flycart').hide();
});

Use the setTimeout to check if a flag you set/unset (I'm using a class) is still valid.

$("#cart-summary").mouseenter(function () {
    $("#cart-summary").addClass("hasFocus");
    setTimeout(function(){ 
        if ($("#cart-summary").hasClass("hasFocus")) {
            $('.flycart').slideDown('fast');
        }
      }, 500 );
      });

$("#cart-summary").mouseleave(function () {
    $("#cart-summary").removeClass("hasFocus");
});


$(".flycart").mouseenter(function () {
    $("#cart-summary").removeClass("lostFocus");    
});

$(".flycart").mouseleave(function () {
    $("#cart-summary").addClass("lostFocus");
    setTimeout(function(){ 
        if ($("#cart-summary").hasClass("hasFocus")) { 
            $('.flycart').slideUp('fast');
            }).find('a.close').click(function(){
            $(this).parents('.flycart').hide();
        }
    }, 500)
});

You could do:

var timeout,
    $flycart = $(".flycart"),
    $summary = $("#cart-summary"),
    delay = 500;

$summary.mouseenter(function () {
    if (timeout) window.clearTimeout(timeout);
    timeout = window.setTimeout(function(){
        if ( $flycart.is(":visible") ) {
            $flycart.slideDown('fast');
        }
    }, delay);
});
$flycart.mouseleave(function () {
    if (timeout) window.clearTimeout(timeout);
    timeout = window.setTimeout(function(){
        if ( $flycart.is(":visible") ) {
            $flycart.slideUp('fast');
        }
    }, delay);
})...

Answer 4

Sounds like you might need the HoverIntent plugin.

I don't know if it'll help you with the mouseout ATLEAST 500ms though. But maybe there's an option in there for that.

offer a solution

var mouseenterTimerCart;
var mouseleaveTimerCart;

$(document).on({
    mouseenter: function () {
        if (mouseleaveTimerCart) clearTimeout(mouseleaveTimerCart);
        mouseenterTimerCart = setTimeout(function() {
            $("#head-cart .cart_items").show()
        }, 500);
    },
    mouseleave: function () {
        if (mouseenterTimerCart) clearTimeout(mouseenterTimerCart);
        mouseleaveTimerCart = setTimeout(function() {
            $("#head-cart .cart_items").hide()
        }, 500);
    }
}, "#head-cart .full, #head-cart .cart_items");

will work if the basket is updated dynamically

$("#head-cart").html(...crat-html-block...)
