javascript - 为什么我的所有按钮的下拉内容都相同

标签 javascript jquery html css twitter-bootstrap

我的页眉中有两个按钮，但是当我单击两个按钮时，内容是相同的。 enter image description here

enter image description here

这就像当我点击一个按钮时我同时点击了两个我不知道为什么。

我认为问题出在我的 jquery 中:

jQuery(document).ready(function($){
//open/close mega-navigation
$('.cd-dropdown-trigger ').on('click', function(event){
    event.preventDefault();
    toggleNav();
});

//close meganavigation
$('.cd-dropdown .cd-close ').on('click', function(event){
    event.preventDefault();
    toggleNav();
});

//on mobile - open submenu
$('.has-children').children('a').on('click', function(event){
    //prevent default clicking on direct children of .has-children 
    event.preventDefault();
    var selected = $(this);
    selected.next('ul').removeClass('is-hidden').end().parent('.has-children').parent('ul').addClass('move-out');
});

//on desktop - differentiate between a user trying to hover over a dropdown item vs trying to navigate into a submenu's contents
var submenuDirection = ( !$('.cd-dropdown-wrapper #botao1').hasClass('open-to-left') ) ? 'right' : 'left';
$('.cd-dropdown-content').menuAim({
    activate: function(row) {
        $(row).children().addClass('is-active').removeClass('fade-out');
        if( $('.cd-dropdown-content .fade-in').length == 0 ) $(row).children('ul').addClass('fade-in');
    },
    deactivate: function(row) {
        $(row).children().removeClass('is-active');
        if( $('li.has-children:hover').length == 0 || $('li.has-children:hover').is($(row)) ) {
            $('.cd-dropdown-content').find('.fade-in').removeClass('fade-in');
            $(row).children('ul').addClass('fade-out')
        }
    },
    exitMenu: function() {
        $('.cd-dropdown-content').find('.is-active').removeClass('is-active');
        return true;
    },
    submenuDirection: submenuDirection,
});

//submenu items - go back link
$('.go-back').on('click', function(){
    var selected = $(this),
        visibleNav = $(this).parent('ul').parent('.has-children').parent('ul');
    selected.parent('ul').addClass('is-hidden').parent('.has-children').parent('ul').removeClass('move-out');
}); 

function toggleNav(){
    var navIsVisible = ( !$('.cd-dropdown').hasClass('dropdown-is-active') ) ? true : false;
    $('.cd-dropdown').toggleClass('dropdown-is-active', navIsVisible);
    $('.cd-dropdown-trigger').toggleClass('dropdown-is-active', navIsVisible);
    if( !navIsVisible ) {
        $('.cd-dropdown').one('webkitTransitionEnd otransitionend oTransitionEnd msTransitionEnd transitionend',function(){
            $('.has-children ul').addClass('is-hidden');
            $('.move-out').removeClass('move-out');
            $('.is-active').removeClass('is-active');
        }); 
    }
}

//IE9 placeholder fallback

if(!Modernizr.input.placeholder){
    $('[placeholder]').focus(function() {
        var input = $(this);
        if (input.val() == input.attr('placeholder')) {
            input.val('');
        }
    }).blur(function() {
        var input = $(this);
        if (input.val() == '' || input.val() == input.attr('placeholder')) {
            input.val(input.attr('placeholder'));
        }
    }).blur();
    $('[placeholder]').parents('form').submit(function() {
        $(this).find('[placeholder]').each(function() {
            var input = $(this);
            if (input.val() == input.attr('placeholder')) {
                input.val('');
            }
        })
    });
}
   });

我试过放置片段，但放置 cdns 链接不起作用。 如果您需要什么，请告诉我。

最佳答案

$('.cd-dropdown') 在 toggleNav 方法中选择所有具有类 cd-dropdown 的元素，而不仅仅是你选择的元素点击。

所以您的 toggleNav 方法会在调用时切换所有下拉菜单。

解决方案:

您需要将需要处理下拉列表的引用传递给toggleNav 方法

$('.cd-dropdown-trigger, .cd-dropdown .cd-close').on('click', function(event){
    event.preventDefault();
    toggleNav($(this).closest('.cd-dropdown-wrapper'));
});

仅在 toggleNav 内处理与该引用相关的元素

function toggleNav(dropdown){
    var navIsVisible = ( !$('.cd-dropdown', dropdown).hasClass('dropdown-is-active') ) ? true : false;
    $('.cd-dropdown', dropdown).toggleClass('dropdown-is-active', navIsVisible);
    $('.cd-dropdown-trigger', dropdown).toggleClass('dropdown-is-active', navIsVisible);
    if( !navIsVisible ) {
        $('.cd-dropdown', dropdown).one('webkitTransitionEnd otransitionend oTransitionEnd msTransitionEnd transitionend',function(){
            $('.has-children ul', dropdown).addClass('is-hidden');
            $('.move-out', dropdown).removeClass('move-out');
            $('.is-active', dropdown).removeClass('is-active');
        }); 
    }
}

PS: $('selector', context) is same as context.find('selector'). You can use the second if it makes code more clear.
