此特征是非标准的,且不在标准轨道中。不要在面向 Web 的生产站点中使用它:它不适用于每个用户。实现之间可能存在大的不兼容性,且行为将来可能改变。

dump() 方法在 WorkerGlobalScope interface allows you to write a message to stdout — i.e. in your terminal, in Firefox only. This is the same as Firefox's window.dump , but for workers.

句法

dump('My message\n');
					

参数

A DOMString containing the message you want to send.

返回

Void.

范例

To write an output from your worker to your computer's terminal, you first have to run an instance of Firefox started from your command line/terminal. For example, on Mac OS X you'd run it using something like this (assuming you are inside the 应用程序 folder):

./Firefox.app/Contents/MacOS/firefox-bin -profile /tmp -no-remote
					

Now go into about:config and enable the browser.dom.window.dump.enabled pref.

Next, run a worker containing the following line:

dump('test\n');
					

This should result in a "test" message being output to the terminal.

规范

This method does not appear in any specification.
