getting undefined in ie (newcell.childnodes[1].type)

my code:

html 

 <table id="coins" class="coins" name="coins">         <tr id="0">        <th>         <label>bills/coins</label>           </th>       <th>                               <label>qty</label>       </th>       <th>                        <label>line amount</label>       </th>       </tr>       <tr id="1">                                  <td>                                                 <cws:productcashlist onchange="productprice(this)"/>           </td>                     <td>           <input name="qty" type="text" id="qty_1" size="10" maxlength="60" value="1" onblur="lineamt(this.id);" />       </td>       <td>           <input name="lineamount" type="text" id="lineamount_1" size="10" maxlength="60" value="0" />             </td>       <td>                                                                       <input class="bluebutton" type="button" id="addrow" value="add" onclick="add('coins');"/>                     </td>       <td style="display:none">                                                                                    <input class="bluebutton" name="deleterow" type="button" id="deleterow_1" value="delete"  onclick="adelete(this.id);" />                     </td>       <td style="display:none">                                                                                  <input name="price" type="text" id="price_1" size="10" maxlength="60" value="1"/>        </td>       </tr>        </tbody>                   </table>

javascript

function add(tableid) {     var table = document.getelementbyid(tableid);     var rowcount = table.rows.length;     var row = table.insertrow(rowcount);     row.id = rowcount;     var colcount = table.rows[rowcount-1].cells.length;      for(var i=0; i<colcount; i++)      {         var newcell = row.insertcell(i);         newcell.innerhtml = table.rows[1].cells[i].innerhtml;                          if(i==4)             newcell.style.display = "none";                                     switch(newcell.childnodes[1].type) {          case "text":                                        newcell.childnodes[1].id = newcell.childnodes[1].name+"_"+rowcount;                if(newcell.childnodes[1].name == "qty")                      newcell.childnodes[1].value = "1";                if(newcell.childnodes[1].name == "price")                  newcell.style.display = "none";               else                 newcell.childnodes[1].value = "0";                             break;                                                                       case "button":                if(newcell.childnodes[1].value == "delete")                       newcell.childnodes[1].id = newcell.childnodes[1].name+"_"+rowcount;                                                     break;           case "select-one":                                   newcell.childnodes[1].id = "id_"+newcell.childnodes[1].name+"_"+rowcount;                newcell.childnodes[1].selectedindex = 0;             break;                                       }                     }     if(rowcount>1)      {         var prerow  = table.rows[rowcount-1];                            var childcell = prerow.cells[3];                        childcell.style.display = "none";         var childcell = prerow.cells[4];         childcell.style.display = "block";                                            } }

please me resolve this.

it looks you're missing opening <tbody> tag. browsers smart , handle fine, others freak out. try adding opening <tbody> , see if still doesn't work in ie.

edit: index childnodes [1]. shouldn't [0]? here's jsfiddle indexes changed: https://jsfiddle.net/nlrru7xw/

edit 2: instead of iterating on of columns , of child nodes , using if statement, may better use little more targeted such queryselector. example:

row.queryselector('input[name="qty"]').value = '1'; row.queryselector('input[name="price"]').display = 'none'; var allinputs = row.queryselectorall('input'); for(var = 0; < allinputs.length; ++i) {     allinputs[i].id = allinputs[i].name + '_' + rowcount; }

this snippet doesn't set same things code tries set, think it's starting point you.

apache - Error with PHP mail(): Multiple or malformed newlines found in additional_header -

-
suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
