Question

我正在创建一个Web程序，它显示同一个mysql数据库中2个表的数据。为此我有一个php文件输出2个json对象（名为hist和hist2）。我试图将表格中的位置显示为Google地图地图中的标记。我在向您展示的行中收到错误Uncaught SyntaxError: Unexpected end of input。

        });         //Here is the Uncaught SyntaxError

      </script>

我将其粘贴在Sublime中，所有内容都显示正常，所以我不知道为什么我会遇到此问题，这也会阻止地图加载。 });关闭了$(json_hist2).each(function() {行。

Answer 1

在return marker2之后添加一个};我相信你并没有关闭原来的准备功能。

获取Uncaught SyntaxError：意外的输入结束
