这篇文章主要介绍了Ajax实现模拟关键字智能匹配搜索效果,当在搜索框输入内容时，根据关键字匹配，显示弹出层，非常不错，具有参考借鉴价值，需要的朋友可以参考下
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
<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();
}
