javascript sleep with SetTimeout

Question

I\'m trying to send emails with a 10 seconds delay between. I wrote this code:

$(document).ready(function() {
    for (i = 0; i < 20; i++) {
        setTi         


        

Answer 1

First, pass a function to setTimeout.

Secondly, you'd be better off if you set the timeout for the next one in the queue after the current one is finished.

In the for loop:

sendEmail(0); // start sending first

and in the callback:

      , function(data) {
          if(id < 19) { // if next should be sent
              setTimeout(function() {
                  SendEmail(id + 1);
              }, 5000);
          }
          var toAppend = "     " + data + ""
          $("#sentTo").append(toAppend);
      }
