jQuery async ajax query and returning value problem (scope, closure)

Question

Code not working because of async query and variable scope problem. I can\'t understand how to solve this. Change to $.ajax method with async:false - not an option. I know about

Answer 1

Just move this code:

cluster = new MarkerClusterer(map, markers, 
{
    maxZoom: null,
    gridSize: null
});

Into the callback function (where your first alert is)

The problem is that with an async request the code will continue to execute even though the request has not completed. So your markers variable isn't set properly until your anonymous callback function is executed.
