javascript - Mongoose find() call inside for loop using a latch -

-

i've been on hours , can't seem find answer. problem have call mongodb inside loop. i'm using latch waits call end before advancing again. here's code:

var latch = true; (var i=0; i<array.length; i++) {     while(latch == false){}     table1.find({}, function(err, result){         ... code ...         latch = true;     });     latch = false; }

the problem doesn't run callback table1.find(), gets blocked on while. can me this?

the loop never proceed past while loop (as you've created infinite loop).

there several ways handle async code within loops in node, including counter variables outside function, , tail-recursion. can see examples here: http://metaduck.com/01-asynchronous-iteration-patterns.html

i big fan of https://github.com/caolan/async provides async.each applies iterator each element in parallel. suit purpose.
