Node.JS: How to pass variables to asynchronous callbacks? [duplicate]

Answer 1

Check this blog out. A variable can be passed by using .bind() method. In your case it would be like this:

var links = ['http://google.com', 'http://yahoo.com'];
for (link in links) {
var url = links[link];

require('request')(url, function() {

    console.log(this.urlAsy);

}.bind({urlAsy:url}));
}
