Question

i’ve a strange problem with JS (probably a noob bug), but i’m stuck with it

In function fillInVersionsList, if i put an alert("tempo") or a break in firebug, i can access to my datas in parameter (ie : alert(pSimulator.simulatorData['LastVersion']) and i’ve the right result. The problem is that if i don’t put an alert/firebug break before my access to datas, i’ve a JS error pSimulator.simulatorData is undefined.

$(document).ready(function() {

    var simulator = new Simulator();

    // Load SimulatorData into the simulator class
    initSimulatorData(simulator);
    // Fill in datas into VersionsList (2nd arg = Id of the list)
    fillInVersionsList(simulator, $('#VersionsList'));  


});

function initSimulatorData(pSimulator)
{
    $.ajax({
      url: "getData.php?action=init",
      success: function(data) {
          pSimulator.initSimulatorData(data);
        }

    });

}


function fillInVersionsList(pSimulator, pSelect)
{
    //alert("tempo");
    alert(pSimulator.simulatorData['LastVersion']);

    pSelect.html('<option>test</option>')       

}

function Simulator()
{

    var simulatorData;


    this.initSimulatorData = function(pSimulatorData)
    {
        this.simulatorData = pSimulatorData;    
    }




}

Is there something to solve this problem?

Thanks in advance

Answer 1

Whats looks like from your problem is that simulator is taking time to initialize and when fillInVersionsList is called pSimulator is still not completely initalized.

When you put an alert it is getting some time delay by which time simulator is initalized.

Check if there is any callback method after simulator is completely initialized and then call fillInVersionsList method after that.

what does initSimulatorData(simulator) does? Is there any asynchronous code invloved in this?
