從左側滑出時，如何在我的幻燈片菜單中添加“慢效果”？

Question

 $(document).ready(function() { $('.slideout-menu-toggle').on('click', function(event) { event.preventDefault(); // create menu variables var slideoutMenu = $('.slideout-menu'); var slideoutMenuWidth = $('.slideout-menu').width(); // toggle open class slideoutMenu.toggleClass("open"); // slide menu if (slideoutMenu.hasClass("open")) { slideoutMenu.animate({ left: "0px" }); } else { slideoutMenu.animate({ left: -slideoutMenuWidth }, 250); } }); }); $(document).ready(function() { $('.slideout-menu li').click(function() { $(this).children('.mobile-sub-menu').toggle("slow"); }); }); 

 .slideout-menu { position: absolute; top: 100px; left: 0px; width: 100%; height: 100%; background: rgb(248, 248, 248); z-index: 1; } .slideout-menu .slideout-menu-toggle { position: absolute; top: 12px; right: 10px; display: inline-block; padding: 6px 9px 5px; font-family: Arial, sans-serif; font-weight: bold; line-height: 1; background: #222; color: #999; text-decoration: none; vertical-align: top; } .slideout-menu .slideout-menu-toggle:hover { color: #fff; } .slideout-menu ul { list-style: none; font-weight: 300; border-top: 1px solid #dddddd; border-bottom: 1px solid #dddddd; } .slideout-menu ul li { /*border-top: 1px solid #dddddd;*/ border-bottom: 1px solid #dddddd; } .slideout-menu ul li a { position: relative; display: block; padding: 10px; color: #999; text-decoration: none; } .slideout-menu ul li a:hover { background: #aaaaaa; color: #fff; } .slideout-menu ul li ai { position: absolute; top: 15px; right: 10px; opacity: .5; } .slideout-menu .mobile-sub-menu { display:none; }

我從互聯網上找到了一些信息，並在切換時在我的移動子菜單中添加了“慢速效果”。

現在，當我從左側滑出時單擊滑出菜單的主要項目（即“ MANUALS”）時，我還想添加此“緩慢效果”。

我怎樣才能做到這一點？

Answer 1

將duration添加到animate 。 這將添加平滑的動畫效果。

slideoutMenu.animate({
    left: "0px"
}, 1000); // 1 second


slideoutMenu.animate({
    left: -slideoutMenuWidth
}, 1000); // 1 second

碼

$(document).ready(function() {
    $('.slideout-menu-toggle').on('click', function(event) {
        event.preventDefault();
        // create menu variables
        var slideoutMenu = $('.slideout-menu');
        var slideoutMenuWidth = $('.slideout-menu').width();

        // toggle open class
        slideoutMenu.toggleClass("open");

        // slide menu
        if (slideoutMenu.hasClass("open")) {
            slideoutMenu.animate({
                left: "0px"
            }, 1000); // 1 second
        } else {
            slideoutMenu.animate({
                left: -slideoutMenuWidth
            }, 1000); // 1 second
        }
    });
});
