javascript - SlickGrid Unselect Row CheckBox Event -

-

i new jquery, , need use grid in project. chose slickgrid (quite slick indeed). need disable buttons when rows deselected.

i using following callback:

grid.onselectedrowschanged.subscribe(function(){});

the problem callback executed on selection - not when rows deselected.

grid.onselectedrowschanged.subscribe(function(){      var selectedrows = grid.getselectedrows();      if (selectedrows.length === 0) {           // (when rows deselected)           // logic goes here...      } });

if want execute logic on row deselect suggest storing selectedrows in global variable updated on selectedrowschanged event. in onselectedrowschanged compare global selectedrows variable , grid.getselectedrows() lenghts see if changes have occured.

var lastselectedrows = [];     grid.onselectedrowschanged.subscribe(function(){      var selectedrows = grid.getselectedrows();      if (selectedrows.length < lastselectedrows.length ) {         // proceed in finding actual row comparing 2 arrays         // rest of logic goes here...       }       lastselectedrows =  selectedrows;  });

!note i'm new in world of slickgrid , may not best solution. think it's worth try.

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
