Why clearInterval doesn't work on a function

阅读更多关于 Why clearInterval doesn't work on a function

问题 this is the code var t = ()=>{ setInterval(()=>{ console.log('hello') },1000) } t(); clearInterval(t) Why the clearinterval does not block execution of the setInterval? 回答1: It doesn't work on a function because that's just now how the mechanism was designed. Calls to setInterval() return a number that acts as an identifier for the timer that the call establishes. That number is what has to be passed to clearInterval() . It doesn't cause an error to pass something that's not a number, or to

Express.js and Zombie.js - Can't seem to parse Javascript assets

阅读更多关于 Express.js and Zombie.js - Can't seem to parse Javascript assets

问题 I have an Express.js app that uses connect-asssets to serve JS and CSS: app.configure(function() { app.set('port', 3000); app.set('views', path.join(__dirname, 'views')); app.set('view engine', 'ejs'); app.use(connectAssets({src: path.join(__dirname, 'assets')})); }); I'm trying to use Zombie.js for acceptance testing, but keep getting SyntaxError: Unexpected token ILLEGAL whenever it tries to parse a Javascript file. If I replace connect-assets with express.static , then the acceptance tests

how can I get connect-assets to recompile my coffee files when they change?

阅读更多关于 how can I get connect-assets to recompile my coffee files when they change?

问题 Related, but hoping for a lower friction answer: How do I use Node and Express with coffeescript and requirejs? I've got connect-assets set up so that I can have .js and .coffee files side by side in my /assets/js folder. Only problem: I have to re-get the page containing any compiled coffee files whenever those files change. Minor problem I guess, but I've been doing a lot of CURL on the files themselves as part of troubleshooting -- doing a CURL on the coffee js file itself won't cause it

How do I set up static serving in Express with an arbitrary start path?

阅读更多关于 How do I set up static serving in Express with an arbitrary start path?

问题 If I want to set up the directory .../whatever/stuff to be served statically, but referenced as http://example.com/mystuff , I tried doing this: app.configure(function() { app.use('/mystuff', _express.static(__dirname + "/whatever/stuff")); app.use('/mystuff', _express.directory(__dirname + "/whatever/stuff")); }); This mostly works, but if I reference a subdirectory of mystuff without a trailing slash, say http://example.com/mystuff/subdir , it redirects to the wrong place ( http://example

How to totally prevent HTTP 304 responses in Connect/Express static middleware?

阅读更多关于 How to totally prevent HTTP 304 responses in Connect/Express static middleware?

问题 At times during development, it would be really nice to prevent HTTP 304 responses (in favor of 200's), and cause the Connect/Express static middleware to read every response from the filesystem, rather than do any caching at all. I have tried playing with maxAge values of 0 and 1, to no avail: app.use(express.static(__dirname + '/public', { maxAge: 1 })) 回答1: I get 200 responses by doing this during development : var express = require('express'); app = express(); app.use(function(req, res,
