Get FX Forward Contracts
When the "Send" button is clicked, the webpage will perform basic validation, then use the given details to call the API, with service name "getFXForwardContracts".
If there are no errors with the information provided, the webpage will proceed to parse a JSON string from "getFXForwardContracts" into "responseObj"
We will be able to import useful data from these 3 sources, and to call a function and store the user ID and PIN.
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.
Then we will get and validate those values we have so far.
This code required data variable from Jsp, please refer to setUserID&setPIN above.
This code required data variable showErrorModal from Jsp, please refer to showErrorModal above.
We will disable Send button
We will set a header object
The header object contains:
Then will use JSON to convert headerObj into var header.
This code required data variable xmlHttp from Jsp, please refer to xmlHttp above.
This code required data variable ApiURL from Jsp, please refer to ApiURL 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.
This code required data variable xmlHttp from Jsp, please refer to xmlHttp above.
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.
This code required data variable onreadystatechange from Jsp, please refer to onreadystatechange above.
This code required data variable xmlHttp from Jsp, please refer to xmlHttp above.
This code required data variable showOTPModel from Jsp, please refer to showOTPModel above.
This code required data variable showErrorModal from Jsp, please refer to showErrorModal above.
Get and Display all the necessary data
We will enable "Send" button.
Once the time is out, it will show error modal: "Timeout invoking API."
Then send the http request.
This code required data variable xmlHttp from Jsp, please refer to xmlHttp above.
This code required data variable ontimeout from Jsp, please refer to ontimeout above.
This code required data variable showErrorModal from Jsp, please refer to showErrorModal above.
Button will be disabled when there is an error occurs.
OTP model update button clicked
This code required data variable setOTP from Jsp, please refer to setOTP above.
Create a function "getRecordCount"
Lastly, for the “getRecordCount” function, If the length of the FXForwardContractList is equal to 0 (there is nothing in the FXForwardContractList), another function will be called: “showErrorModal”, an error will be displayed “There are no record.”. If the length of the FXForwardContractList is equal to undefined, it will return 1 and the length of the FXForwardContractList.
This code required data variable showErrorModal from Jsp, please refer to showErrorModal above.
