JavaScript

Add Standing Instruction

When the "Send" button is clicked, the webpage will perform basic validation,

then use the given details to call the API, with service name "addStandingInstruction".

If there are no errors with the information provided, the webpage will proceed to

parse a JSON string from "addStandingInstruction" into "responseObj".

The Standing Instruction will be added and updated in the server.

We will be able to import useful data from these 3 sources, and to call a function and store the user ID and PIN.

Put the value of getUserID() into the value of userID.
Put the value of getPIN() into the value of PIN.

getUserID&getPIN

This code required data variable from Jsp, please refer to getUserID&getPIN above.

We will create a function and a header. The header will contain servicename, userID, PIN.

serviceName: addStandingInstruction
userID
PIN
OTP

Then we will get and validate those values we have so far. We will create a variable:

AccountFrom
AccountTo
TransactionAmount
NextDateTime
IsRecurring
transactionReferenceNumber
weekly_monthly
narrative

If the AccountFrom is equal to nothing, the error will be displayed as "Account From cannot be blank."

If the AccountTo is equal to nothing, the error will be displayed as "Account To cannot be blank."

If the TransactionAmount is equal to nothing, the error will be displayed as "Transaction Amount cannot be blank."

If the NextDateTime is equal to nothing, the error will be displayed as "Next Date Time cannot be blank."

If the IsRecurring is equal to nothing, the error will be displayed as "Is Recurring cannot be blank."

setUserID&setPIN

This code required data variable from Jsp, please refer to setUserID&setPIN above.

showErrorModal

This code required data variable showErrorModal from Jsp, please refer to showErrorModal above.

We will disable Send button

Then we will set some request parameters:

headerObj contains:

serviceName: serviceName
userID: userID
PIN: PIN
OTP: OTP

contentObj contains:

accountFrom: AccountFrom
accountTo: AccountTo
transactionAmount: TransactionAmount
transactionReferenceNumber: transactionReferenceNumber
nextDateTime: NextDateTime
isRecurring: IsRecurring
weekly_monthly: weekly_monthly
narrative: narrative

Then we will use JSON to convert headerObj and contentObj into var header and var content.

JSP

This code required data variable from Jsp, please refer to Jsp above.

Set up http request.

If xmlHttp is equals to nothing, the web page will display an alert message:"Browser does not support HTTP request."

If xmlHttp is not equal to nothing, the web page will return data from the url and the header."

The timeout will be 5000s.

xmlHttp

This code required data variable xmlHttp from Jsp, please refer to xmlHttp above.

ApiURL

This code required data variable ApiURL from Jsp, please refer to ApiURL above.

Setup http event handlers。If globalerrorID = "010041", return OTP. Else if globalerrorID not = "010000", return error details.

onreadystatechange
