Re: jQuery Ajax won't return data

[asgallant]

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?

I ma trying to get data using jqery.ajax from a servlet but it is not returning data.  However, when I run the servlet url in the browser, it displays the data.

The code is as shown below:  Both the success and error does not return anything.  Can anybody please assist.

function drawChart() {

       var result=null;

       $.ajax({
