Language related topic for DatePicker

[JerryWang]

In SAP help, the determination of language code / locale is explained.

For example, when I access CRM application "My Appointment" with English language specified in url:

Https://<host>:<port>/sap/bc/ui5_ui5/ui2/ushell/shells/abap/FioriLaunchpad.html?sap-client=001&sap-language=EN#Appointment...

The DatePicker looks like below:

When I try with Chinese:

Https://<host>:<port>/sap/bc/ui5_ui5/ui2/ushell/shells/abap/FioriLaunchpad.html?sap-client=001&sap-language=ZH#Appointment...

What I woud like to know is how is "2015年10月15日" displayed.

Based on previous research on DatePicker, this task should be a little bit easier:

- DateFormat in DatePicker control

- More details of DatePicker

1. The place holders for Date display ( 年 - year, 月 - month, 日 - day ) for Chinese are stored in this.aFormatArray in DateFormat.js file.



2. this.aFormatArray is determined by this.oFormatOptions.pattern. For language = ZH, the patter is "y年M月d日".



3. In Chrome network tab, we can observe a http request for file zh_CN.son.



The callstack which triggers this file request:



If we inspect the content of this file, we can find the "y年M月d日" in attribute dateFormat-medium and dateFormat-long:



The content of this file is parsed and merged into this.mData, which will be used to populate aFormatArray mentioned above.
