Bootstrap 导航栏菜单徽标不起作用
Arb*_*bid 4 html css jquery twitter-bootstrap twitter-bootstrap-3
请查看此Bootply或下面的Code Snippet，我使用 Bootstrap 3.1 是因为我想在我的网站上使用这个很棒的搜索框。但是我遇到了一个问题，导航栏徽标不起作用（它甚至没有悬停，因此无法点击）。
注意：品牌标志在移动版本中工作正常，只有桌面版本有问题。因此，如果您正在运行以下代码片段，请单击全屏查看问题。
我不是一个 css 人，所以你们能帮我解决这个问题吗？谢谢

将徽标优先于其他元素。
添加
.navbar-brand {
position: relative;
z-index: 1;
}
现在搜索在展开时覆盖/优先于徽标，
改变
.navbar-collapse form[role="search"] {
z-index: 2;
}
.navbar-brand {
position: relative;
z-index: 1;
}
.navbar-collapse form[role="search"] {
z-index: 2;
}
$(function() {
// Remove Search if user Resets Form or hits Escape!
$('body, .navbar-collapse form[role="search"] button[type="reset"]').on('click keyup', function(event) {
console.log(event.currentTarget);
if (event.which == 27 && $('.navbar-collapse form[role="search"]').hasClass('active') ||
$(event.currentTarget).attr('type') == 'reset') {
closeSearch();
}
});
function closeSearch() {
var $form = $('.navbar-collapse form[role="search"].active')
$form.find('input').val('');
$form.removeClass('active');
}
// Show Search if form is not active // event.preventDefault() is important, this prevents the form from submitting
$(document).on('click', '.navbar-collapse form[role="search"]:not(.active) button[type="submit"]', function(event) {
event.preventDefault();
var $form = $(this).closest('form'),

$form.addClass('active');
$input.focus();
