input 输入框自动联想功能

2017-04-14 23:47 447 查看

上面的是效果图，通过输入的值在数据库中进行查询进而进行联想使用

重点注意 1 jsp中引用的文件要全版本不能太老 2界面的字符编码方式utf-8 否者有可能出现中文联想不对的

前端jsp代码

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>My JSP 'index.jsp' starting page</title>

$(function(){
var search = $("#search");

var source = new Array();//[{"name":"zhangkun"},{"name":"dashen"}]//["aab","aac","bbd","bbn"];

search.autocomplete({
source:source,
messages: { //message设置不出现匹配关键字的结果
noResults: '',
results: function() {}
}
});

search.keyup(function(){
$.ajax({
type:"POST",
url:"/springmvc_mybatis/user/search.action",
data:{search:$("#search").val()},
success:function(data){
var obj = eval(data); //将json转换为对象的方法
for(var i = 0; i < obj.length; i++){
source[i] = obj[i].username;
}
}
});
});
});
</script>
</head>
<body>
<label for="acount">自动联想输入</label>
<input type="text" id = "search" autocomplete="off">
</body>

</html>

sql语句 mybatis
<select id="selectByLike" parameterType="java.lang.String" resultType="cn.itcast.ssm.po.User">
select * from user where username like concat("%",#{key},"%")
</select>

后端支持代码springmvc 做的返回对象的json字串使用mybatis

/**
* @author zhangkun
*/
@Controller
@RequestMapping("/user")
public class UsersCotroller {
@Autowired
private UserService userService;
@RequestMapping("/search")
/**
* @param search ajax提交上来的输入框的值
* @return 返回装有user对象的list的json字串
*/
public @ResponseBody List<User> search(String search){ //
System.out.println(search);
return userService.searchByLike(search);
}
}
