Missing parameter in Ajax post to Asmx

Question

I\'m trying to send the string File to my asmx service and I keep getting the following error:

    Message: Invalid web service call, missing va         


        

Answer 1

Try sending the data as a plain object:

data: { 'File': File },

Or as a string:

data: 'File=' + File,

At the moment you're doing a little of both which won't work.
