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.
dump('My message\n');
A
DOMString
containing the message you want to send.
Void.
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.
This method does not appear in any specification.
