javascript - Form under Loop construct not working as expected -


improper form submission

for below code snippet, not able value input hidden field in request.

in form table created:

it working fine, if click approve button of first row.

issue faced when approve button of intermediate row clicked. there no value passed in request id="hidinput";

<script> function fetchid(){ var contentid = document.getelementbyid("testid").innerhtml; document.getelementbyid("hidinput").value=contentid; } </script>            <%for (appl_testimonial_txn testimonial_txn : results) {%>          <tr>         <form action="<%=approve.tostring()%>" method="post">              <td id="testid"><%=testimonial_txn != null ? testimonial_txn                         .gettestimonialid() : ""%></td>              <input type="hidden" name="rowid" id="hidinput" value=""/>             <td><button class="button-continue continuenew" type="submit"                          onclick="fetchid()">approve</button></td>             </form>         </tr>         <%}%>

please find below screen capture of table. enter image description here

as per code above, there no way figure out row in approve button clicked. can pass testimonial id fetchid function.

<script>     function fetchid(contentid){       document.getelementbyid("hidinput").value=contentid;     }     <script>   
    <tr>     <form action="<%=approve.tostring()%>" method="post">          <td><%=testimonial_txn != null ? testimonial_txn                     .gettestimonialid() : ""%></td>          <input type="hidden" name="rowid" id="hidinput" value=""/>         <td><button class="button-continue continuenew" type="submit"                      onclick="fetchid('<%=testimonial_txn != null ? testimonial_txn                     .gettestimonialid() : ""%>')">approve</button></td>         </form>     </tr>     <%}%>

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
