融合表映射中的标记计数 [英] Marker count in fusion table map
问题描述
我浏览了以下两个链接:第一和第二< a>其中解释了如何在融合表映射层中添加标记的计数。我尝试了同样的技术在我的示例地图,但它没有工作。实际上,我需要关键的,最优的,正常的转基因的计数,单独和所有的总和。
I went through these two links: first and second which explains how to add count of marker in fusion table map layer. I tried the same technique in my sample map but it didn't work. Actually i need the count of critical, optimal, normal transforers seperately and the total of all. Also i want to know that can I add these counts in map legend?
推荐答案
一年多前,我发布了一个答案示例代码是在第一链接中采用的相同方法。 http://stackoverflow.com/a/9778985 。请参阅getFTCount()函数。
这两个示例的问题是它们是旧的,并使用已弃用的FT SQL API,而不是V1.0 API。
Over a year ago, I posted an answer with example code which is the same approach taken in your "first" link. http://stackoverflow.com/a/9778985. See the getFTCount() function. The problem with both these examples is that they are old and use the deprecated FT SQL API, not the V1.0 API.
您需要一个Google API密钥。和jQuery。您需要在代码中更改的一件事是:
You will need a Google API key. And jQuery. The one thing you'll need to change in the code is:
var apiKey = "XXXXXX";
var queryUrlHead = 'https://www.googleapis.com/fusiontables/v1/query?sql=';
var queryUrlTail = '&key=' + apiKey + '&callback=?';
更新:我修复了jsfiddle几个问题:
Update: I fixed your jsfiddle to make it work. Couple of issues:
- 新的API返回data.columns和data.rows,而不是data.table.rows。
- 我想新的API返回json整数,而不是字符串,jquery似乎反对传递数字到$(#div_id)。html()或.append()。
注意:计数之前的空字符串
Note: the empty string before the count number
$ #count')。html((''+ data.rows [0]));
