<p>下面列出了 JavaScript 抛出的错误。这些错误是有用的调试帮助，但报告的问题并不总是十分明了。下面的页面提供有关这些错误的详细信息。每个错误都是基于 <a href="Reference/Global_Objects/Error" title="通过Error的构造器可以创建一个错误对象。当运行时错误产生时，Error的实例对象会被抛出。Error对象也可用于用户自定义的异常的基础对象。下面列出了各种内建的标准错误类型。"><code>Error</code></a>  的对象，并且具有名称和消息。</p>
<p>Web 控制台中显示的错误可能包含指向下面相应页面的链接，以帮助您快速理解代码中的问题。</p>
