java - How to get week of year figure in GWT -

-

is there simple way how week of year information date object or millis time in gwt on client side?

something this:

date date = new date(); date yearstart = new date(date.getyear(), 0, 0);  int week = (int) (date.gettime() - yearstart.gettime())/(7 * 24 * 60 * 60 * 1000);

note give week in date object, has no time zone information. when use it, may have adjust using time zone information.

javascript - Which segment of a polyline was clicked? -

-
i have set sample polyline 5 segments , , i'm allowing new markers created when user clicks on polyline. i'd know if there's foolproof way determine whether new marker between markers 0 , 1, or 1 , 2 ... or between 4 , 5. i've considered checking if new marker inside bounding box, , point-in-line formulas, neither 100% precise. as google maps uses mercator projection projecting gps coordinates, can't use 'line equation' gps coordinates, because projection not linear gps points.but instead can use world coordinates linear. here have used parametric form of line equation check whether point on segment: function ispointonsegment( map, gpspoint1, gpspoint2, gpspoint ){ var p1 = map.getprojection().fromlatlngtopoint( gpspoint1 ); var p2 = map.getprojection().fromlatlngtopoint( gpspoint2 ); var p = map.getprojection().fromlatlngtopoint( gpspoint ); var t_x; var t_y; //parametric form of line equation is: //-...
