Javascript function only continuing after the 'else'

                    var messages = result;
                    for(var i=0;i<messages.length;i++) 
                        jQuery("#responseMessages").jqGrid(
                                                            'addRowData',
                                                            i+1,
                                                            {distance:messages[i].distance,age:messages[i].age,message:messages[i].message}
                                                          );
                },
                error: function (error) {

                }
            });
        }

So it's only making the AJAX call if it goes through the 'else' part of the if statement, not the others. Why?

Milimetric actually got it right, I believe - you're missing the semicolon in your jsonData object literal definition. That combined with JavaScript's auto-semi-colon insertion and the way your braces {} are written to begin on a new line, is very likely the problem. Put in a semi-colon in there and it should work fine.

In other C-like languages, putting the opening brace on a new line or on the same line is a personal preference but in JavaScript, it does make a difference and so I'd recommend you make a conscious effort to put opening braces on the same line.
