当我检查控制台时,我得到了第一行没有定义的Uncaught ReferenceError说法$.我假设它指的是第一行的第一个字符.我从网站上获得了这个代码,我是新手,jQuery所以我不确定这里出了什么问题.
有什么建议?

更改包含脚本的顺序(首先是jQuery):
<script src="http://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<script type="text/javascript" src="./javascript.js"></script>
<script
src="http://maps.googleapis.com/maps/api/js?key=YOUR_APIKEY&sensor=false">
</script>

首先包含jQuery文件:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<script type="text/javascript" src="./javascript.js"></script>
<script
src="http://maps.googleapis.com/maps/api/js?key=AIzaSyCJnj2nWoM86eU8Bq2G4lSNz3udIkZT4YY&sensor=false">

脚本按照您在HTML中定义它们的顺序加载.
因此,如果您首先加载:
<script type="text/javascript" src="./javascript.js"></script>

然后先不加载jQuery $ is not defined.
您需要先加载jQuery才能使用它.
出于性能原因,我还建议将脚本放在HTML的底部.
