javascript - AngularJS - Filter list by object property that has filter applied to it -


i want filter list of objects properties , used filter filter. problem object properties have filters applied them change format in displayed (see formatdate filter in code below) , filter filter use unformatted object properties.

e.g.: there video .duration = 150 (seconds) displayed 00:02:30 (because of formatdate filter). if user searches "02", video not found because .duration property of video searched , "02" doesn't match 150.

what easiest way filter displayed value instead of "raw" value?
thought adding getdurationformatted() function every object in list , displaying , filtering property, severely decrease expressiveness of html.

<input ng-model="query">  <tr ng-repeat="video in videos | filter:query">     <td>         {{ video.name }}     </td>     <td>         <!-- formatdate filter used format amount of seconds -->         {{ video.duration | formatdate:'hh:mm:ss' }}     </td> </td>

you can extend every object in array additional preformatted property corresponding users see. filtering work user friendly input.

this simplest solution requires minor template modification:

<tr ng-repeat="video in videos | filter:query">     <td>         {{ video.name }}     </td>     <td>         <!-- formatdate filter used format amount of seconds -->         {{ video.durationformatted = (video.duration | formatdate:'hh:mm:ss') }}     </td> </tr>

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.
