一、頁面
index.ftl
<html>
<head>
<meta charset="utf-8">
<script type="text/javascript" src="js/jquery.js"></script>
</head>
<body>
<form action="",method="POST">
<select id="city"></select>
<input type="button" value="提交" onclick=("doSubmit()");>
</form>
</body>
<script>
$(document).ready(function(){
$.ajax({
contentType : "application/json;charset=utf-8",
type : "POST",
url : "queryCity.html" ,
dataType : "json",
success : function(data) {
alert("ss");
$.each(data, function(i, city) {
$('#city').append(
$('<option>').text(city.city).attr('value',
city.id));
});
}
});
});
</script>
</html>
二、controller檔案
CityController.java
package com.lx.controller;
import java.util.ArrayList;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
import com.lx.entity.City;
import com.lx.service.CityService;
@Controller
public class CityController {
@Autowired
private CityService cityService;
@RequestMapping(value="/queryCity",method=RequestMethod.POST)
public @ResponseBody ArrayList<City> xialacaidanPOST(HttpServletRequest request,HttpServletResponse response){
ArrayList<City> city =cityService.queryCity();
return city;
}
}
