2. var obj_data = {};
3.   obj_data['key'] = keystring;  // Ex. Keystring: $easydb->key="x2nrdIpAmdorqMj4";
4.   var textData = new FormData();  
5.   $.each(obj_data, function(k, v) { // apply object key/values to formData
6. console.log(['Key, Value: ', k, v]);
7. textData.append(k, v);
8.   });
9.   $.ajax({
10.     method: 'POST',
11.     url: 'assetPath/easydbkeysetup.php',
12.     data: textData
13.   })
14.   .done (function(response) {
15.       var rout = response.text;
16.       $('#easydbcredentialswrapper_stacks_in_20_page0 .success-message p').append('<span>' + rout + '</span>');
17.   })
18.   .fail (function(response) {

20.       $('#easydbcredentialswrapper_stacks_in_20_page0 .error-message p').append('<span>' + rout + '</span>'); 
21.   });

Here's an example page:  [ Removed ]

I think it might be in my ajax call.  When I comment it out, the error disappears, although might be in append.

Note: just have one key/value in this, but want to be able to handle many if needed.

So where is my code goofed up?
