Get Customer Types
We need to import useful data from these 4 sources, and to load 4 different types of functions below.
There is a function called "loadReferenceData". It contains 4 different types of functions:
The "loadReferenceData" function is to ensure functions are executed sequentially. Without it, these 4 functions above are not be able to execute.
We will create a function called: getCustomerTypeName.
customerType is the data that we are going to match.
Then, we will use for loop to loop customerTypes, and use an empty variable cusType to store all the looped customerTypes(Every time to loop customerTypes, there will be different value coming out.).
If CustomerTypeID in the variable custType can match customerType, then it will return the CustomerTypeName from the variable custType.
Else, if CustomerTypeID in the variable custType cannot match customerType, then it will return undefined.
We will create an empty variable customerTypes(used in function getCustomerTypeName(customerType)) and a function "loadCustomerTypes".
Then, we will set request parameters by creating a variable headerobj:
The header contains:
Then set up http request and http event handlers.
If globalErrorID is equal to "010000"(means no error),
customerTypes will contain all the data in responseObj.Content.ServiceResponse.CustomerTypeList.CustomerType.
Else, the system will come out an alert message: "Error retrieving document type list."
Once time is out, the system will come out an alert message: "Timeout retrieving document type list."
