使用api制作我的足迹地图

查看我的足迹

很早的时候看到别人博客的足迹地图，就想着自己也搞一个，但是没找到相关的技术文章。不知道从何下手，前两天有了思路就做了起来。可以网上找地图的素材也可以用百度高德的开放平台做，还有一些其他的jQuery地图插件，也可以做出很漂亮很酷炫的地图，不过感觉没有百度地图这样的。。。。

我是用的百度地图api，所以说说怎么利用百度地图来做。

因为之前没接触过，所以一直觉得很复杂，也没有仔细看官方的api文档。

今天做完，发现很简单啊。记录一些遇到的一些问题。

开发的话照着官方给的demo来，完全OK的。

百度地图JavaScript API：http://lbsyun.baidu.com/index.php?title=jspopular3.0

地图示例：http://lbsyun.baidu.com/jsdemo.htm#a1_2

可以说是很详细了，基本满足需求。还可以自定义地图的样式，控件等。

不过这个自定义样式有点烦，我调试半天背景色啥的发现还是默认的看的顺眼。但是又不想用默认的，就随便套了个皮肤。

一般是先写个静态页面做地图，然后用IFRAME标签引用到需要展示的地方。

这里需要注意的就是子页面接收值得问题，我是这样做的(地图标注内容是数据库中的数据)：

首先在后台将需要传到前台的list转化为json格式

1 2 3 4 5

List footPrintList = footPrintService.selectAll(footPrint);         String jsonString = JSON.toJSONString(footPrintList);         JSONArray jsonArray = JSONArray.parseArray(jsonString);           model.addAttribute("footPrintList", jsonArray);

然后前台使用一个隐藏域接收，注意因为json里面有双引号，所以value需要使用单引号，不然接收的值有问题。

1 2 3 4

"hidden" id="footPrintList" name="footPrintList" value='${footPrintList}' /> "https://www.zjhuiwan.cn/zjblog/show.html"                 style=" margin: 1px 0 0 1px;width: 1000px;height:480px;"                 scrolling=yes ALLOWTRANSPARENCY="true">

然后IFRAME标签里的子页面通过父页面id取值然后遍历，组成自己需要的数据。

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

// 接收父页面的数据，并遍历加载         var footPrintList = $("#footPrintList", window.parent.document).val(); //子页面获取父页面元素取值         var packJson = JSON.parse(footPrintList);          Date.prototype.toLocaleString = function() {               return this.getFullYear() + "-" + (this.getMonth() + 1) + "-" + this.getDate();         };         for (var i = 0; i < packJson.length; i++) {             //将时间毫秒格式改为自定义格式             var unixTimestamp = new Date(packJson[i].creationTime) ;             var commonTime = unixTimestamp.toLocaleString();             //标注点击显示的内容             var sContent = "" +packJson[i].fName+"    "+ commonTime+ "" +                 " + packJson[i].iUrl + "' width='140' height='105' title='" + packJson[i].fName + "'/>" +                 "" + packJson[i].description + "... " +                 "文章链接: + packJson[i].aUrl + "'>" + packJson[i].aTitle + " " +                 "";             var infoWindow = new BMap.InfoWindow(sContent); // 创建标注信息窗口对象             //根据经纬度创建标注             var point = new BMap.Point(packJson[i].longitude, packJson[i].latitude);             addMarker(point, infoWindow);         }

然后还有就是如果你网站是https的话地图引用百度api的时候也要用https。

1 2	"text/javascript"     src="https://api.map.baidu.com/api?v=3.0&ak=。。。">

地图标记点可以是鼠标移上去触发事件，也可以是点击事件。

1 2 3 4 5 6 7 8

//将click改为mouseover即为鼠标滑过时间             marker.addEventListener("click", function() {                 this.openInfoWindow(infoWindow);                 //图片加载完毕重绘infowindow                 document.getElementById('imgDemo').onload = function() {                     infoWindow.redraw(); //防止在网速较慢，图片未加载时，生成的信息框高度比图片的总高度小，导致图片部分被隐藏                 }             });

还有一些关于地图的问题就不多说了，api文档都能够查得到，照着来就是了，以下地图页面的完整代码：
