Question

我正在使用jQuery web提供的jQuery UI自动完成功能，我正在尝试自己设置样式。

当将鼠标悬停在自动填充的选项上时，我希望更改背景，但不会更改所有选项。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）。我知道我只是要更改.ui-menu .ui-menu-item并且那些小边框不属于它（我的意思是，我猜），所以我想知道如何更改我的CSS样式所以一切都包含在徘徊效应。

整个代码片段：

var searcher = document.getElementById('buscador');

searcher.onclick = magiaNegra;


    var availableTags = [
      "ActionScript",
      "AppleScript",
      "Asp",
      "BASIC",
      "C",
      "C++",
      "Clojure",
      "COBOL",
      "ColdFusion",
      "Erlang",
      "Fortran",
      "Groovy",
      "Haskell",
      "Java",
      "JavaScript",
      "Lisp",
      "Perl",
      "PHP",
      "Python",
      "Ruby",
      "Scala",
      "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

您可以使用班级.ui-state-focus，因为当您悬停时，li会自动添加悬停状态。

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

Answer 2

您可以尝试将左右填充从ui-menu移动到ui-menu-item类。像这样：

.ui-menu
{
    position: relative;
    list-style: none;
    background-color: white;
    border-radius: 18px;
    z-index:10;
    box-shadow: 5px 0px 8px white;
    width: 214px;
    line-height: 200%;
    font-size: 18px;
    padding: 15px 0;
    border: solid 1px grey;

}
.ui-menu .ui-menu-item
{
    margin: none;
    padding-left: 15px;
    padding-right:10px;
}
