[RESOLVED] post serializeArray()

**sNagheenanajar** · 12-03-2010, 05:21 PM

I need some assistance with sending JSON to the server. When I make this post using $('#trfFilterForm').serialize() I can view that URL-encoded string on my server (cherrypy). When I make the post using $('#trfFilterForm').serializeArray() the server responds with status of 400 Bad Request (I'm not even touching the JSON on the server side at this point). Is there something else I need to be doing to the JSON data before I post it?

Code:

...
var filters = $('#trfFilterForm').serializeArray();
//var filters = $('#trfFilterForm').serialize();
...
$.post('getMarkers', {
    filters: filters
}, function(data){  
         ...
}, 'json');

What does serializeArray return?

**sNagheenanajar** · 12-07-2010, 10:19 AM

It returns an Array of Objects (name, value pairs).
http://api.jquery.com/serializeArray/

So it looks like serializeArray is including extra information in each object in the array. Could this be the cause of the error? The jquery docs do not mention this __proto__ object.

Code:

[Object
name: "trfHVFilter"
value: "6.6"
    __proto__: Object
    __defineGetter__: function __defineGetter__() { [native code] }
    __defineSetter__: function __defineSetter__() { [native code] }
    __lookupGetter__: function __lookupGetter__() { [native code] }
    __lookupSetter__: function __lookupSetter__() { [native code] }
    constructor: function Object() { [native code] }
    hasOwnProperty: function hasOwnProperty() { [native code] }
    isPrototypeOf: function isPrototypeOf() { [native code] }
    propertyIsEnumerable: function propertyIsEnumerable() { [native code] }
    toLocaleString: function toLocaleString() { [native code] }
    toString: function toString() { [native code] }
    valueOf: function valueOf() { [native code] }
]

Here is the content returned instead of the JSON array I would normally expect.

HTML Code:

    #traceback {
