一、首先我先说一下,网上有很多案例,不过我试了很多,都是有一些问题的。
比如:大小写区分、按键盘上下键跳行等问题,下面是我简化和修复了的作品。
二、本地静态数据案例(网上案例很多这个不多说)
1、html页面代码
2、 实例下载地址:http://download.csdn.net/detail/zhao1991123/9670655
二、Ajax+Thinkphp+bigAutocomplete后台动态获取数据
1、html页面代码
- PHP页面代码
public function searchlist(){
$key=$_POST['qkskey'];
$M=M();
$sql="这里是数据库查询语句不多说";
$data = $M->query($sql);
$this->ajaxReturn($data);
}
-
修改jquery.bigautocomplete.js文件,我这里是把ajax请求直接写入了js文件里。
注意:这里是修改部分ajax请求。
if(data != null && $.isArray(data) ){
var data_ = new Array();
$.ajax({
type: "POST",
async:false,
contentType: "application/x-www-form-urlencoded; charset=utf-8",
url: "?s=/Home/Info/searchlist",
data: {"qkskey":$("#searchID").val()},
dataType: "json",
success:function(data){
for(var i=0;i -1){
data_.push(data[i]);
}
}
}
})
4、jquery.bigautocomplete.js文件
// JavaScript Document

var bigAutocomplete = new function(){

144,19,145,40,38,27];//键盘上功能键键值数组
