Getting TypeError: invalid 'in' operand obj while fetching data using ajax

Question

Below is my ajax call

 $(document).ready(function() {
     $("#blog").focusout(function() {
         alert('Focus out event call');
         alert('hello');
         $.ajax({
             url: '/homes',
             method: 'POST',
             data: 'blog=' + $('#blog').val(),
             success: function(result) {
                 $.each(result, function(key, val) {
                     $("#result").append('<div><label>' + val.description + '</label></div>');
                 });
             },
             error: function() {
                 alert('failure.');
             }
         });
     });
 });

I am getting 'TypeError: invalid 'in' operand obj ' error in my console

In advance thank you

Your code is missing a closing });. Is this bad cut-and-paste or the underlying cause? — Adrian Wragg

Mention a dataType attribute in your ajax call.It consider text by default.That's why not able to iterate on result

dataType:'json'

Because your result should be array or json

Shouldn't data be an object?

data: {
    blog: $('#blog').val()
},

No; api.jquery.com/jQuery.ajax states that it can be an object or a string.
