Deferred and Ajax

Question

Reading a JSON-Service like this:

$.ajax({
  url:\'activeIDs\',
  success : function(data){ // data = [14,15]
    var tableRows = [];
    for (var dataIndex=0; d         


        

Answer 1

You'll need to wait for all requests to finish before alerting.

$.ajax({
  url:'activeIDs',
  success : function(data){ // data = [14,15]
    var tableRows = [];
    var requests = [];
    for (var dataIndex=0; dataIndex < data.length; dataIndex++) {
      var isLast = dataIndex == data.length;

      var request = $.ajax({
        url: 'info?id=' + data[dataIndex]
      }).done(function(data2) { // "foo", "bar"
        tableRows.push(data2.name);
      });

      requests.push(request);
    }

    // wait for all requests to finish here
    $.when(requests).then(function(){
      // all success functions have been called and updated things appropriately
      alert(tableRows.length);
    }
  }
});

This assumes that all requests succeed. It also looks like there are a few typos

• Where does tableRows get updated?
• Where is entries defined?

Edit Now using promise style success handler. Should push the result in to tableRows before calling the $.when().then callback
