javascript - 样式化 jQuery 自动完成

Question

我正在使用 jQuery web 提供的 jQuery UI 自动完成功能，并且我正在尝试自己对其进行 css 样式设置。

当鼠标悬停在自动完成的选项上时，我希望背景发生变化，但它并没有改变全部。您会注意到顶部、左侧、底部和右侧的小边框(我猜它们是边距)。我知道我只是指定更改 .ui-menu .ui-menu-item 而那些小边框不是它的一部分(我的意思是，我猜)，所以我想知道如何我可以更改我的 css 样式，以便所有内容都包含在悬停效果中吗？

完整代码片段:

var searcher = document.getElementById('buscador');

searcher.onclick = magiaNegra;


    var availableTags = [
      "ActionScript",
      "AppleScript",
      "Asp",
      "BASIC",

      "Scheme"
    ];

function magiaNegra()
{
	var master = searcher.parentNode;
	searcher.style.animationName = "expandismo";
	searcher.style.animationDuration = "0.5s";
	setTimeout(function(){
		master.removeChild(searcher);
		var barraSearch = document.createElement('input');
		barraSearch.setAttribute('type', 'text');
		barraSearch.setAttribute('id', 'barraSearch');
		barraSearch.setAttribute('class', 'form-control');
		barraSearch.setAttribute('placeholder', 'Buscar...');
		var botonCheto = document.createElement('button');
		var secondSpan = document.createElement('span');
		botonCheto.setAttribute('type', 'button');
		botonCheto.setAttribute('id', 'searchBox');
		secondSpan.setAttribute('class', 'glyphicon glyphicon-search');
		secondSpan.setAttribute('aria-hidden', 'true');
		botonCheto.appendChild(secondSpan);
		
		master.appendChild(barraSearch);
		master.appendChild(botonCheto);
		barraSearch.focus();
		 $( "#barraSearch" ).autocomplete({
		       source: function(request, response) {
			        var results = $.ui.autocomplete.filter(availableTags, request.term);
			        
			        response(results.slice(0, 3));
			    }
		    });

	}, 500);

Answer 1

您可以使用 .ui-state-focus 类，因为悬停状态会在您悬停时自动添加到 li 上。

.ui-autocomplete.ui-menu .ui-menu-item.ui-state-focus { background-color: rgba(0,0,0,0.4); }
