Hi Shuang,
I hope I understood correctly, if not we can refine 
.
- you have some selection UI (dropdown box for example) where you have list of years. the outupt is always a year...
- then, you want to create a longer string of 52 weeks (with the format yyyy.ww) and pass as a filter.
passing as a filter should be simple, DS_1.setFilter(dim, <the-string>);
how to make the string, here a simple variant - I have used the Array component (Design Studio SDK: Array Util Component). In case you do not want to use any SDK, just write - I show you how to create an array without SDK.
exxample is located also in this script (based on 1.3 SP1):
Release Adding Example for Filtering on Weeks · KarolKalisz/DesignStudioBiAppRepository · GitHub
Name:SCN_FILTER_WEEKS
Sample code:
you need to fill in the dropdown (in my case in onStartup):
DROPDOWN_1.addItem("--seelct--", "Select Year ...");
DROPDOWN_1.addItem("2012", "Year 2012");
DROPDOWN_1.addItem("2013", "Year 2013");
DROPDOWN_1.addItem("2014", "Year 2014");
DROPDOWN_1.addItem("2015", "Year 2015");and then on selection, this code will bring you back the filter string:
// this will return eg. 2014
var selectedYear = DROPDOWN_1.getSelectedValue();
if(selectedYear != "--seelct--") { var eachesArray = ARRAY_1.eaches(1, 52, 1); eachesArray.forEach(function(element, index) { var week = "" + (index + 1); if(week.length < 2) { week = "0" + week; } ARRAY_1.addValue(selectedYear + "." + week); }); var allValues = ARRAY_1.getValues(";"); TEXT_2.setText(allValues);
} else { TEXT_2.setText("! select Year!");
}how to download the Array SDK (and other funny stuff): refer to Karol's SDK Components
does this help you?
