D3JS没有在WAMP上工作

时间：2014-01-04 02:12:07

标签： php d3.js

编辑2：我找到了this article并在我的网站的根目录中创建了一个.htaccess文件，其中包含以下两行：

AddType image/svg+xml svg svgz
AddEncoding gzip svgz

但仍然没有错误，没有图表。可能是WAMP设置问题吗？正如我所说，这段代码适用于我的在线网站...

编辑：我在代码中放置了“alert（d.max_energy）”，我可以看到JSON值返回到客户端页面。它只是没有被处理成图表，也没有抱怨错误。

我确信这是一个简单的修复，但我看不到它。我在托管网站上有以下代码可以正常工作，现在已经在WAMP本地服务器（我的网络中与开发PC不同的机器）中复制，但是在Console / Inspect中没有执行/导致错误。

感谢任何帮助。

在inverterdata.php文件中我有以下代码：

当我通过浏览器地址栏手动执行一个PHP脚本调用时，我得到了有效的JSON，如下所示：

http://10.0.0.13/sma/sma-php/inverterdata.php?var=PLIFE&id=P100023

JSON：

[{"xaxis":"2012","max_energy":"305923.303","max_efficiency":"13019.572"},{"xaxis":"2013","max_energy":"410400.643","max_efficiency":"17466.284"},{"xaxis":"2014","max_energy":"4538.187","max_efficiency":"193.140"}]

我在标签内的HTML是：

<svg id="daychart"></svg>
<svg id="weekchart"></svg>
<svg id="monthchart"></svg>
<svg id="yearchart"></svg>
<svg id="lifechart"></svg>

咄！我知道它在我面前但是看不到它...当我在单词按下时将标签添加到页面主体时我在“视觉”框中而不是“文本”框中执行了它，这搞砸了所有标签...
