Hello,
I getting started with node.js and its asynchronous nature is making me
wonder how to solve this problem.
Consider the following piece of code:
=======================
var fs = require('fs');
var reader = require ("buffered-reader");
var DataReader = reader.DataReader;
function test() {
var hash = [];
new DataReader ("./sunrise.csv", { encoding: "utf8" })
.on ("eof", function() {
console.log(hash);
})
.on ("line", function (line){
var reg = new RegExp(";", "g");
var fields = line.split(reg);
var value = fields[0];
var key = fields[1];
hash[key] = value;
console.log (hash[key]);
})
.read ();
console.log(hash);
}
test();
=======================
console.log(hash) displays [], most probably because it gets executed
before the ".on ("line", function (line){...}" piece...
Could you let me know how to tell it to wait? What I want to do ultimately
is load a bunch of files into an associative array and ONLY THEN do
something with it.
Any insights would be very much appreciated.
Cheers
JM
