JavaScript problem of MAP control

Question

Hi, all.
A javascript problem occured in my web site. Could you please help me?
I want to control the "car-icon.gif" to move in some time interval.
When I use the source code of partA, it can work well.  While I change the source code to partB with loop control by "for()", it can not work.
Anyone can tell me how to do?
Thanks.

    var arglat = 35.69031083620262;  
    var arglng = 139.70000267028814;
    timeinterval = 1000;


partA:
------>>>>
    window.setTimeout(function() { AddPushpin(arglat, arglng + 0.0002, 'Vehicle 999231', 'Time: ' + new Date().toTimeString(), layer, 'car-icon.gif'); }, 2000);
    window.setTimeout(function() { AddPushpin(arglat, arglng + 0.0003, 'Vehicle 999232', 'Time: ' + new Date().toTimeString(), layer, 'car-icon.gif'); }, 3000);
    window.setTimeout(function() { AddPushpin(arglat, arglng + 0.0005, 'Vehicle 999233', 'Time: ' + new Date().toTimeString(), layer, 'car-icon.gif'); }, 5000);
    window.setTimeout(function() { AddPushpin(arglat, arglng + 0.0006, 'Vehicle 999234', 'Time: ' + new Date().toTimeString(), layer, 'car-icon.gif'); }, 6000);
    window.setTimeout(function() { AddPushpin(arglat, arglng + 0.0007, 'Vehicle 999235', 'Time: ' + new Date().toTimeString(), layer, 'car-icon.gif'); }, 7000);
    window.setTimeout(function() { AddPushpin(arglat, arglng + 0.0008, 'Vehicle 999236', 'Time: ' + new Date().toTimeString(), layer, 'car-icon.gif'); }, 8000);
    window.setTimeout(function() { AddPushpin(arglat, arglng + 0.0009, 'Vehicle 999237', 'Time: ' + new Date().toTimeString(), layer, 'car-icon.gif'); }, 9000);

partB:

    for (var j = 0; j < 7; j++) {

Hi,

Looks like tmptimeinterval is not defined.  Up above you have it set as timeinterval (without a var declaration also).  See simplified sample code below:

 var arglat = 35.69031083620262;  
 var arglng = 139.70000267028814;
 timeinterval = 1000; 
   
  for (var j = 0; j < 2; j++) {
        window.setTimeout(function() { alert(arglat + arglng)}, tmptimeinterval);
        arglng = arglng + 0.0001;
        tmptimeinterval = tmptimeinterval + 1000; 

Hope that helps,
