javascript - When the checkbox is checked, insert numbering on table td - 


<td>     <apex:inputfield value="{!child.confirm_order__c}" /> </td>     //checkbox <td>     <!-- <apex:panelgroup rendered="{!child.confirm_order__c==true}">-->     <apex:inputfield value="{!child.order_numbering__c}" id="getindex" />       //text field     <!-- </apex:panelgroup>--> </td> <apex:commandbutton value="save" action="{!save}" onclick="insert_numbers()" />

html:

<table> <th><td>checkbox value</td><td>inputfield value</td></th> <tr> <td>true</td><td>1</td> <td>false</td><td></td> </tr> <tr> <td>true</td><td>2</td> <td>false</td><td></td> </tr> </table>

javascript :

<script>     function insert_numbers() {         $("[id$=getindex]").each(function(index) {             $(this).val(index + 1)         })     } </script>

currently working fine. inserts number every td.

i want modify in such way when checkbox checked, numbers inserted in input field td 1, 2, 3... (i want insert number td checkbox checked .remaining blank)

(or)

i won't show input field td whenever checkbox not checked. want number td input field visible.

currently not inserting if td not avaliable in middle of row.

how can this?

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.
