javascript - Column Chart: Click event to only trigger on drilldown series -


i working on 2 level column chart. want perform task showing alert on clicking each bar on chart on drilldown series only. have found this:

plotoptions: {     series: {         cursor: 'pointer',         point: {             events: {                 click: function () {                     alert('category: ' + this.category + ', value: ' + this.y);                 }             }         }     } }

it works fine, fires parent series too. can force click event work on 2nd level series (that appears after drilldown)?

because this value of click event object no values if click parent, check x value (or similar) see if destroyed parent or clicking available point. make sure it's value know point have.

for example (jsfiddle):

var undefined;  $('#container').highcharts({     plotoptions: {         series: {             point: {                 events: {                     click: function() {                         if(this.x != undefined)                             alert("it's alive!");                     }                 }             }         }     }     // ... });

if concerns specific series consider adding event code specific series, instead of doing general code series.

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.
