jquery - Limit select2 selections by group? -


has come way limit select2's selection group?

i'm hoping auto-remove selection same group once group selected (effectively limiting 1 selection per group)

i'll working on , post here if nobody posts solution before i'm finished.

it possible prevent selections being made in select2, can done depending on how "group" defined. if "group" <optgroup> in standard <select>, it's matter of checking see if other options in <optgroup> have been selected, , prevent in-progress selection based on that.

select2 emits select2:selecting event when selection being made, , event can prevented calling preventdefault() on it.

$("#myselect").on("select2:selecting", function (evt) {   var data = evt.params.data;   var $element = $(data.element);    // check if options in group selected   if ($element.parent("optgroup").find(":selected").length) {     evt.preventdefault();   } });

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
