本文主要是介绍superMap使用javascript加载WMTS服务图层，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
首先下载SuperMap_iClient_8C(2017)_SP1_for_JavaScript，

在根目录下新建GettingStarted.html内容如下：

<body onload="init()"><div id="map" style="left:0px;right:0px;width:800px;height:500px"></div>
</body>
</html>//当前图层的分辨率数组信息,和matrixIds一样，需要用户从wmts服务获取并明确设置,resolutions数组和matrixIds数组长度相同
将WMTS服务用浏览器打开即可看到xml的信息，从中获取所需的layer、style、matrixSet、format、resolutions这些字段信息。
信息如图所示：
将TitleMatrix中的所有resolution写进数组，matrixIds的个数跟resolution一样即可。
