html - how to disable previously selected select options displayed using bootstrap selectpicker and ng-options -


i have multi select dropdown. need when user lands on page, need restrict him modify previous selections, disable options inside dropdown. here html -

<div>     <select multiple class="form-control selectpicker" ng-model="selectednames" data-live-search="true" ng-options="opt.name opt in availablenames track opt.id" ng-change="onnamechange()"> </select> </div>

tried suggestions link - http://silviomoreto.github.io/bootstrap-select/

but if add option tag manually when using ng-options, doesn't displayed. tried using ng-repeat rather ng-options ng-repeat dropdown stopped showing tick-marks against selected values & default displayed - "no values selected", though model still had them.

any pointers how achieve without resorting jquery ?

thanks anup

use disable when syntax in ngoptions. refer ngoptions docs more details. add key in ngoptions indicate if field selected user eg. prevselected: true , tell ngoptions disable option when key set/exists.

<select ng-model="mycolor" ng-options="color.name disable when color.prevselected color in colors"></select>

example on plnkr

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.
