几天后，Google maps api突然在Chrome中生成错误。不是在Firefox中

Question

正确显示地图，dierction和距离，但脚本停止，我的网站的其余部分未在Chrome中显示。 它能是什么？

我找到了错误的原因。 下面的代码是正确的。 这一个：

    <script    src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"  type="text/javascript"></script>

     don`t likes that:

    <script  src='http://maps.googleapis.com/maps/api/js?key=AIzaSyCsWAeW4gm1P1f-pyYhiAkkE&libraries=places'></script>

 in one file.

 I put the first one in a different file. Everything works fine again.
 The only question is why the error came suddenly, over night?

代码：
