easyui-combobox 下拉列表的JSON獲取資料例子
1. 使用easyui需要匯入的包：
<script type="text/javascript" src="js/easyui/jquery.min.js"></script>
<link rel="stylesheet" type="text/css"href="js/easyui/themes/default/easyui.css" />
<link rel="stylesheet" type="text/css" href="js/easyui/themes/icon.css" />
<script type="text/javascript" src="js/easyui/jquery.easyui.min.js"></script>
1.index.jsp頁面寫一個簡單的下拉類表
<script type="text/javascript">
$(function() {
$("#city").combobox({
valueField : "id",
textField : "text",
url : "city.jsp",
});
$("#city").combobox("select",function(value){
return value+1;
});
});
</script>
<span>城市：<input name="city" id="city" class="easyui-combobox" /> </span>
1.city.jsp
<%@page import="net.sf.json.JSONArray"%>
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://"
+ request.getServerName() + ":" + request.getServerPort()
+ path + "/";
List<Map<String, String>> list = new ArrayList<Map<String, String>>();
for (int i = 1; i < 6; i++) {
Map<String, String> map = new HashMap<String, String>();
map.put("id", i + "");
map.put("text", "city" + i);
list.add(map);
}
//轉化為JSON資料
String str = JSONArray.fromObject(list).toString();
response.getWriter().write(str);
//System.out.println(str);
