javascript - Get eq( ) and nth-child of table -


i have following table:

<table id="some-table"> <thead>   <tr>     <th>name</th>     <th>type</th>     <th>ui status</th>     <th>engine status</th>  </tr> </thead> <tbody> <tr>     <th>a</th>     <th>1</th>     <th></th>     <th></th> </tr> <tr>     <th>b</th>     <th>2</th>     <th></th>     <th></th>  </tr> </tbody> </table>

i want insert ui status table @ index.

$(#'some-table tbody tr').eq(0) me row want how 3rd th in tr can update ui status.

any appreciated.

thanks.

you can chain calls find children in element:

$(#'some-table tbody tr').eq(0).find('th').eq(2)

you can use :eq pseudo class in selector:

$(#'some-table tbody tr:eq(0) th:eq(2)')

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.
