javascript - Checkbox changed event does not call event after return true from clientside -


i have checkbox , function 

<asp:checkbox id="ckbtest" runat="server" cssclass="label" text="responsible persons"      autopostback="true" onclick="return foo()" />   function foo(){                 if (false) {                   alert('some alert.');                   return false;                   }                   else{                   return true;                   }                 }

when click on checkbox , returns true function after not going server side

i suppose go serverside after return true function

server side method

protected sub ckbtest_checkedchanged(byval sender object, byval e system.eventargs) handles ckbtest.checkedchanged          try      code         catch ex exception          end try      end sub

presuming foo() java-script function . code needs be

<asp:checkbox id="ckbtest" runat="server" cssclass="label" text="responsible persons" onclientclick="return foo()" />

the attribute onclick fires server side functions , autopostback property automatically initializes post server.

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.
