常见的想当然

HTML script tags and inline event handlers execute automatically in JSDOM, and any unhandled script exceptions throw synchronous runtime errors from the JSDOM constructor.

这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。

契约

• Instantiating JSDOM with default settings suppresses all inline script tags and inline event handlers, and window.eval throws a ReferenceError because no VM context is attached.
• Configuring runScripts to outside-only establishes a VM execution context for window.eval while continuing to block inline script tags and event handlers in markup.
• Configuring runScripts to dangerously executes inline script tags and event handler attributes within the JSDOM window context.
• Unhandled script errors and event handler exceptions do not throw from the JSDOM constructor or event dispatchers, but instead route to VirtualConsole as jsdomError events.
• VirtualConsole sendTo forwards console logging methods while supporting omitJSDOMErrors to filter out uncaught script exceptions.
