“搜索”可以使我们更快的找到某一个关键词或者某一个商品，所以“模糊查询”和“下拉匹配”也成了前端必备的一个小技能，开门见山，希望对朋友们有帮助。

因为是用了bootstrap框架，所以引入了bootstrap的样式，自我调整哈<link rel="stylesheet" href="css/bootstrap.css" rel="external nofollow" >

样式写好以后就是js实现下来匹配了，最主要的是jquery.bigautocomplete.js的引入

<script src="js/jquery-3.1.1.js"></script><script src="js/index.js"></script><script src="js/jquery.bigautocomplete.js"></script>

// 隐藏的搜索框下拉列表$(function () { var num = 0; $("#tt").bigAutocomplete({ width: 543, data: [{title: "牛栏山<span class='keyRightSpan'>约5个结果</span>", result: {ff: "qq"}}, {title: "郎酒<span class='keyRightSpan'>约2个结果</span>"}, {title: "茅台<span class='keyRightSpan'>约4个结果</span>"}, {title: "五粮液<span class='keyRightSpan'>约2个结果</span>"}, {title: "水井坊<span class='keyRightSpan'>约7个结果</span>"}, {title: "汾酒<span class='keyRightSpan'>约3个结果</span>"}, {title: "洋府<span class='keyRightSpan'>约2个结果</span>"}, {title: "董酒<span class='keyRightSpan'>约5个结果</span>"}, {title: "剑南春<span class='keyRightSpan'>约2个结果</span>"}, {title: "劲酒<span class='keyRightSpan'>约8个结果</span>"}], callback: function (data) { console.log(data.title); } });})

接下来就是这个效果的截图

可以鼠标悬浮时选中某一个关键词，然后点击的时候把它的值（value）放在input框里
