How to get exact error message from ajax

How to print exact error for given ajax snippet. Actually I am calling my .php script which returns the data fetched from database in json format. And while running this it shows me some error i.e alert box of error popups, so how to find exact error over here?

$.ajax({  
        type: "POST",  
        dataType: 'json',
    // url: "store_locator.php",  
        url : "http://localhost/GoogleMaps/store_locator.php",
        data: parameters,  
        success: function(msg) {  
            //alert(msg);
            displayStores(msg);
        },
        error:function (xhr, ajaxOptions, thrownError){
            alert("Error : "+thrownError);
        }    
    });

you can check the "responseText" values of the first item of the error function so like error: function(XMLHttpRequest, textStatus, errorThrown) { alert(XMLHttpRequest.responseText); } should show you the contents of the error

Sounds like you are trying to debug. So in order to do that these are some things you could try:

use 

xhr.status

to check the status code returned by the server which will give you a clue as to what is going on. Status codes and meanings

then 

xhr.responseText

may give you some additional info.

As mentioned in comments use the console to see network traffic and JavaScript errors - in IE or Chrome you can push F12 to bring up the developer tools.

To answer the question this JSFiddle shows how to handle the error response returned and get available details from it.
