Get Stock Symbols


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 8 different types of functions:



The "loadReferenceData" function is to ensure functions are executed sequentially. Without it, these 8 functions above are not be able to execute.








We will create a function called: getStockSymbolName.

StockListSymbol is the data that we are going to match.

Then, we will use for loop to loop StockSymbols, and use an empty variable product to store all the looped StockSymbols(Every time to loop StockSymbols, there will be different value coming out.).

If symbol in the variable StockSymbol can match StockListSymbol, then it will return the company from the variable StockSymbol.

Else, if symbol in the variable StockSymbol cannot match StockListSymbol, then it will return undefined.






We will create an empty variable StockSymbols(used in function getStockSymbolName(StockListSymbol)) and a function "loadStockSymbols".

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),

StockSymbols will contain all the data in responseObj.Content.ServiceResponse.StockSymbolList.StockSymbol.

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."
