I'm not quite sure what is going on here, as I've never used callbacks with
async set to false. It should work if you use this:
var result = $.ajax({
url:"http://localhost:8081/mHealth/MapData";,
type:"get",
dataType:"text",
async:false,
error: function(result){
alert("There is no data to populate the map.");
}
}).responseText;
Alternatively, you could make it asynchronous and put the rest of your code
into the success callback and see if that works.
If you direct the ajax query to a non-existent URL, does the error code run?
