菜单图标动画jQuery

标签: javascript jquery html css

单击切换菜单中的导航图标时会触发动画(将“汉堡包”图标转换为“X”),导航菜单会下降。

当用户点击导航图标或激活切换菜单外(菜单已下拉)时,“X”图标将变回“汉堡包”图标。

我遇到的问题是,即使切换菜单未处于活动状态(菜单未下拉)且用户在页面某处的导航栏外部点击,导航图标动画仍会被触发。

任何寻求修复的帮助都表示赞赏: - )!

jQuery的:

/*navigation icon animation*/
jQuery(document).ready(function() {
$('#toggle-menu').click(function(){
$(this).toggleClass('menu-is-active')
});

/* click outside of nav to trigger navigation icon animation*/
$(document).click(function() { $("#toggle-menu").toggleClass(); });         $("nav").click(function(e) { e.stopPropagation(); return false; });

/*----/----navigation icon animation*/

/*toggle menu*/
jQuery("#toggle-menu").click(function() {
jQuery(".nav").slideToggle();
});
/* click outside of nav to close toggle*/
$(document).click(function() { $(".nav").hide(); }); $("#toggle-      menu").click(function(e) { e.stopPropagation(); return false; });
/*----/----toggle menu*/

});

HTML:

<div class="header">
<div class="navbar">

<a href="" class="logo" style="display: inline-block;">LogoPlaceHolder</a>

我注意到只有当我第一次通过点击&#34; hamburger&#34;来切换课程时才会发生这种情况。然后我通过点击文档关闭它(如果我通过单击&#34; X&#34关闭它;一切正常对我来说)。然后,即使您没有指定文档,单击文档时的切换类也将切换相同的类。

我在文档点击时尝试了removeClass()而不是toggleClass(),它对我来说很好。

简单的解决方案:

/ 导航图标动画 /

var trigger='X';

jQuery(document).ready(function () {
    $('#toggle-menu').click(function () {
        trigger='X';
        $(this).toggleClass('menu-is-active')

    });

    /* click outside of nav to trigger navigation icon animation*/
    $(document).click(function () {


        if (trigger=='X')
        {
          $("#toggle-menu").toggleClass();
          trigger='ham';
        }



    });
    $("nav").click(function (e) {
        e.stopPropagation();
        return false;
    });

    /*----/----navigation icon animation*/

    /*toggle menu*/
    jQuery("#toggle-menu").click(function () {
        jQuery(".nav").slideToggle();
    });
    /* click outside of nav to close toggle*/
    $(document).click(function () {
        $(".nav").hide();
    });
    $("#toggle-menu").click(function (e) {
        e.stopPropagation();
        return false;
    });
    /*----/----toggle menu*/

});
