Have you tried to sniff the http traffic?

Richard Deeming 30-Sep-15 14:13pm

Your form is set to post to "prescavi/comparar", but your AJAX request is posting to "comparar". Which is the correct relative URL?

Nosfa 30-Sep-15 14:52pm

comparar is a function inside prescavi controller.

it starts the function but only returns
"you entered and"- meaning the variables are empty

Richard Deeming 30-Sep-15 14:59pm

Try passing a javascript object, instead of a string:
data: { 'presc1': presc1, 'aviad1': aviad1 }

still the same

Solution 2

Hi,

data: "{'presc1':'" + presc1 + "', 'aviad1':'" + aviad1 + "'}",

Please Remove '' quotes

try this one its work out

data : JSON.stringify({ presc1: presc1 , aviad1: aviad1 }),

and one more thing below code your missing semicollon

C#

var presc1 = $('#p1').val(),
                    aviad1 = $('#a1').val(),

Modify that

C#

var presc1 = $('#p1').val(),
                    aviad1 = $('#a1').val();

Thanks

no. still the same.

(the semicolon issue happened because I truncated other variables. after the last on i do have the semicolon)

I think the error is on the controller side.
Must I put httppost?
ActionResult?

thanks

ok.
what happens is that the script is not running!
The form method/action is calling the controller, therefor no data is passed.
if I take those off. nothing happens, the form shows blanks and the address bar changes to http://localhost:16844/input/index?p1=28258&a1=52445&p2=&a2=&p3=&a3=&p4=&a4=&btnSubmit=comparar

#btnsubmit should work.

XML

I think the error is on the controller side.
Must I put  <HttpPost>?
ActionResult?
