2018-06-23 19:33 来源:未知 编辑:admin

“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。

<div class="gover_search">
  <div class="gover_search_form">
    <form action="#" method="post" name="searchform" id="searchform" class="searchinfo">
      <ul>
        <li>
          <input type="text" id="tt" value="" class="text" autocomplete="off" />
          <p class="search"><img src="img/search-1.png" alt=""></p>

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>

---搜索框模糊查询带下拉匹配效果-js---

// 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
