我有一个在我的网站上绘制多边形地图的功能。
通过错误控制它 TypeError：k [bd] .maps.Load不是函数

在帖子中我发现原因是“js的重复”。我在脚本中找不到哪个js文件重复。
注意：如果我删除main.js，它可以在firefox中运行。它在chrome中不起作用
答案 0 :(得分：1)
删除所有 <script>...</script>行但这一行：
<script src="http://maps.google.com/maps/api/js?sensor=false&libraries=drawing" type="text/javascript"></script>
因为它将加载所有必需的脚本文件，包括main.js - 这是复制的来源。
