准备数据keyword.json：（这里只贴出部分数据）

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

html结构

   

js：

//当在搜索框输入内容时，根据关键字匹配，显示弹出层 functionsearchSuggest(obj){  varsearchKey=$(obj).val();  varreg =newRegExp(searchKey,"i");//忽略大小写匹配搜索框中输入的内容  $.ajax({  type:"get",  url:"data/keyword.json",  dataType:"json",  success:function(data){   vararr=[];   for(vari=0,len=data.length;i"+data[i].keyword+"");   }   }       $(".keywords_list").html(arr).show();  }  }); } //单击匹配列表中的关键字选项时，将该关键字显示在搜索框中 functionchangeSearchKey(obj){  varvalue=$(obj).text();  $("#searchKey").val(value);  $(".keywords_list").hide(); }
