Jquery-ui自动完成和Bootstrap 3固定导航栏

标签： twitter-bootstrap jquery-ui twitter-bootstrap-3 jquery-ui-autocomplete

我正在尝试使用jquery ui和twitter bootstarp进行自动完成搜索。我在导航栏中添加了一个简单的搜索框，一切似乎都运行正常。请查看下面的代码段，或者您也可以在此JSFiddle上看到相同的代码，只需输入“a”，它就会自动在下拉列表中显示结果。

问题在于平板电脑和移动版的导航栏导航栏，例如默认情况下显示平板电脑版本的代码段，因此bootstarp导航栏调整其高度，但是当我在平板电脑或移动版本上搜索时，自动完成结果会留在导航栏后面，这是固定位置。我试图用z-index和更改.ui-autocomplete {position:relative;}解决这个问题，但没有什么对我有用。下面是这个问题的图片。

请看下面的代码段，谢谢 

$(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'),
				$input = $form.find('input');
			$form.addClass('active');
			$input.focus();

		});
    });

您需要使用important关键字。类似的东西：

.ui-autocomplete { z-index:2000 !important; }
