How do I wait for the modal selected value?

I trigger to show the modal when user click on some element and ask them to make a choice.

Currently is to choose one color out of two.

And then I will use the color selected to create some element and add to the document.

I tried to use global variable to store the choice but that is too slow for my element creation.

Is there a synchronize way to wait for the modal to return value?

The following is invoked when user click on a specific element

var SelectedColor = '#0000FF'; //global variable
function CreateRoute(marker) {
//create route
var vertex = [];
vertex.push(marker.getLatLng());
//Block here and ask for color
SelectedColor = null;
$("#ChooseColor").dialog('open');
//this one should wait callback
var polyline = createGPolyline(vertex, SelectedColor, 5, 0.5);
$gmap.addOverlay(polyline);
polyline.enableDrawing({});
GEvent.addListener(polyline, "endline", function() { BindEditRoute(polyline) });
GEvent.addListener(polyline, "lineupdated", function() { UpdateRoute(polyline) });
}

What should I do to work around this?

Because JavaScript is single-threaded and JavaScript is being used to display the dialog and handle any clicks on it, there's no way to block execution until the user clicks one button or another, as this would block the UI entirely. The solution is to use callback functions, like so:

If you're not using the buttons option, you want your callback bound to whatever element the user clicks inside the dialog to make a selection.
