In this case, I would simply not use an anonymous function. Instead, give your function a name and call it like so:

$('#find').click(function(){ bounds = google.maps.Polygon.prototype.getBounds(); north = bounds.getNorthEast().lng(); south = bounds.getSouthWest().lng(); west = bounds.getSouthWest().lat(); east = bounds.getNorthEast().lat(); //console.log(north); //console.log(south); //console.log(west); //console.log(east); function getPostCodes(data){ if(!data) { north = north + 0.00002; south = south - 0.00002; west = west - 0.00002; east = east + 0.00002; //need to run get json again! $.getJSON('/properties/search/get-postcodes-in-area/north/'+north+'/south/'+south+'/west/'+west+'/east/'+east, getPostCodes); return; } // If you make it here, you've got your result! } $.getJSON('/properties/search/get-postcodes-in-area/north/'+north+'/south/'+south+'/west/'+west+'/east/'+east, getPostCodes); });
