我在表单中使用了Google Maps API (Places Library) autocomple。
如果有任何错误，例如错误的API密钥，没有域白名单或通过例外达到Google的配额限制。在某些情况下，API甚至禁用输入并插入图标。捕获所有Google API Javascript异常
是否有办法捕捉所有类型的异常？ try/catch块不起作用。
我的目标是，即使API存在错误，表单应该照常工作，只是没有自动完成。
要重现此问题只是试图从谷歌的例子代码用假API密钥这是在脚本源定义：

你能否解释进一步关于什么是 “一个try/catch块没有工作。”手段？ –
@DaveCooper我把每一个函数放在'try {/ * Code * /} catch（err）{concsole.log（err）; '' – Pawel
