i have saved form data inside variable, , passed on variable send() function. 

var params = {     'problem[avatar]': $.report_image_view.reportphoto.toimage(), // returns [ti.blob] object     'problem[title]': $.report_title_view.title.value,     'problem[description]': $.report_description_view.description.value,     'problem[ptype]': $.report_type_view.report_type.value['valueid'],     'problem[status]': 1,     'problem[priority]': 2,     'problem[latitude]': latitude,     'problem[longitude]': longitude,     'problem[user_id]': 2 }  // prepare connection. client.open("post", url); client.send(params);

way #2

what have done is, instead of saving form data inside variable, , passing on variable, i've created object form data parameter pass function.

client.open("post", url); client.send({     "problem[avatar]" : $.report_image_view.reportphoto.toimage(), // returns [ti.blob] object     "problem[title]" : $.report_title_view.title.value,     "problem[description]" : $.report_description_view.description.value,     "problem[ptype]" : $.report_type_view.report_type["valueid"],     "problem[status]" : 1,     "problem[priority]" : 2,     "problem[latitude]" : latitude,     "problem[longitude]" : longitude,     "problem[user_id]" : 2 });

var post_data =  "problem[title]=report rest client&problem[latitude]=18.09&problem[longitude]=-67.12&problem[ptype]=1&problem[status]=1&problem[priority]=2&problem[description]=test description rest client&problem[user_id]=2&problem[address]=123 main street, pr";  // prepare connection. client.open("post", url);            client.send(post_data);

this time organize params object in different way. otherwise, similar way #1

this time i'm creating object in way #4 passing directly send() method parameter, in way #3.
