When I click save button I want to send all dropdown chosen value and other table data to servlet. I am not been able to send to servlet .Please help me.

[Dormilich]

did you check what your HTTP request actually is?

[ruby88]

Yes I set as application/json to it. I am getting json value as [{ "AccountNo": "89348734", "AccountType": "Credit", "Account Type_Val": "21", "AccountStatus": "Invalid" }] Thank you.

[ruby88]

Is it the right format? How can I loop through this value in servlet?

[Dormilich]

servlets are Java, not JavaScript.

[ruby88]

Yes I understand Dormilich.But what I am having problem is my json format form javascript. I am not been able to get correct jsonstringarray in javascript.As per above my code,I am taking values from every dropdown event change.and wanting to save those data to servlet. since my servlet could not loop through becuase of json format. Thank you.

the JSON rersponse given hardly matches with the AJAX coding, there is accountNo vs. accountNumber, accountTypeID does not exist, etc.

additionally, if the jQuery AJAX call is not set to json, you may need to parse the response first.

PS. console.log() is way more descriptive than alert()
