老板是搞交通的,要我从高德上抓数据放到自己的数据库中。说做就做!
一、工具
1、VisualStudio2010
或其他Html编辑器
2、Access数据库
使用mysql或其他数据库需要服务器支持,这里为了方便就使用access
3、IE浏览器
二、步骤
获取高德地图点的属性
使用JavaScript代码alert 出poiArr[i]对象的所有属性,为创建表格做准备
建立Access数据库表
依据上面所得出的数据,创建poi表,字段有id(主键)、name、type、latitude、lotitude、longitude、address和tel。
为了方便,全部使用文本类型
编写Html代码

三、实验效果
打开网页,在关键词搜索框中输入要搜索的地点
在下拉列表框中选择对应的地点
发现地图出现与搜索地点相关的几个点
然后打开access数据库表
发现记录数增加
四、实验注意要点
连接数据库时mdb文件必须给出绝对路径
这里采用的方法是把mdb文件和html文件放在同一目录下,利用html文件获取目录的路径
代码片段如下
var filePath = location.href.substring(0,location.href.indexOf("GaodeToaccess.htm"));
var path = filePath + "hzyGaoDe.mdb";
//去掉字符串中最前面的"files://"这8个字符。
pathpath = path.substring(8);
varconn=new ActiveXObject("ADODB.Connection");
conn.Open("DBQ="+pathpath+";DRIVER={MicrosoftAccess Driver (*.mdb)};");
主键不要重复
插入数据时传的id最好使用高德地图点对象的Id,这样可以保证主键不会重复,数据可以顺利插入
代码片段如下
addStation(poiArr[i].id,poiArr[i].name,longitude,latitude,poiArr[i].type,poiArr[i].address,poiArr[i].tel);
