在帖子中我发现原因是“js的重复”。我找不到我的脚本中重复的 js 文件。

note: if i remove main.js, it works in firefox. it doesn't work in chrome

Answer 1

删除全部 <script>...</script>但这一行:

<script src="http://maps.google.com/maps/api/js?sensor=false&amp;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 - 这就是重复的来源。
