[ {"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
<form class="fl search_form" action="#" method="post"> <input class="search_text" id="searchKey" type="search" placeholder="请输入搜索关键字" onkeyup="searchSuggest(this);"/> <input class="search_btn" type="submit" value="搜索"/> </form> <!--start--智能搜索关键字匹配弹出层--> <ul class="keywords_list"></ul> <!--end--智能搜索关键字匹配弹出层-->
js：
//当在搜索框输入内容时，根据关键字匹配，显示弹出层 function searchSuggest(obj){ var searchKey=$(obj).val(); var reg = new RegExp(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){ 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>"); } } $(".keywords_list").html(arr).show(); } }); } //单击匹配列表中的关键字选项时，将该关键字显示在搜索框中 function changeSearchKey(obj){ var value=$(obj).text(); $("#searchKey").val(value); $('.keywords_list').hide(); }
