準備數據keyword.json：（這里只貼出部分數據）

[  {"id":1,"initial":"ad","keyword":"奧迪"},  {"id":2,"initial":"ada4l","keyword":"奧迪A4L"},  {"id":3,"initial":"ada6l","keyword":"奧迪A6L"},  {"id":4,"initial":"adq5","keyword":"奧迪Q5"},  {"id":5,"initial":"ada3","keyword":"奧迪A3"},  {"id":6,"initial":"adq7","keyword":"奧迪Q7(進口)"},  {"id":7,"initial":"ada8","keyword":"奧迪A8L(進口)"},  {"id":8,"initial":"bm","keyword":"寶馬"},  {"id":9,"initial":"bm5x","keyword":"寶馬5系"},  {"id":10,"initial":"bm7x","keyword":"寶馬7系"},  {"id":11,"initial":"bt","keyword":"本田"},  {"id":12,"initial":"bqsbx25","keyword":"北汽紳寶 X25"},  {"id":13,"initial":"bqsbx35","keyword":"北汽紳寶X35"},  {"id":14,"initial":"bqsbx55","keyword":"北汽紳寶X55"} ] 

html結構

<form class="fl search_form" action="#" method="post">  <input class="search_text" id="searchKey" type="search" placeholder="請輸入搜索關鍵字" onkeyup="searchSuggest(this);"/>  <input class="search_btn" type="submit" value="搜索"/> </form> <!--start--智能搜索關鍵字匹配彈出層--> <ul class="keywords_list"></ul> <!--end--智能搜索關鍵字匹配彈出層--> 

js：

//當在搜索框輸入內容時，根據關鍵字匹配，顯示彈出層 function searchSuggest(obj){  var searchKey=$(obj).val();  var reg = new RegExp(searchKey,"i"); //忽略大小寫匹配搜索框中輸入的內容  $.ajax({  type:"get",  url:"data/keyword.json",  dataType:"json",  success:function(data){   var arr=[];   for(var i=0,len=data.length;i<len;i++){   if(searchKey!="" && (data[i].initial.search(reg)!=-1 || data[i].keyword.search(reg)!=-1)) {    arr.push("<li onclick='changeSearchKey(this);'>"+data[i].keyword+"</li>");   }   }       $(".keywords_list").html(arr).show();  }  }); } //單擊匹配列表中的關鍵字選項時，將該關鍵字顯示在搜索框中 function changeSearchKey(obj){  var value=$(obj).text();  $("#searchKey").val(value);  $('.keywords_list').hide(); }
