javascript - Adding new row to HTML table dynamically with JScript -


i writing code in html + jquery , need add rows table dynamically.

i've written code add rows dynamically, doesn't seem work.

here jscript code :

<script language="javascript">         function addrow(tableid) {             var table = document.getelementbyid(tableid);              var rowcount = table.rows.length;             var row = table.insertrow(rowcount);              var cell1 = row.insertcell(0);             var element1 = document.createelement("input");             element1.type = "date";             element1.name="datebox[];             element1.id = "dt";             cell1.appendchild(element1);              var cell2 = row.insertcell(1);             cell2.innerhtml = rowcount + 1;             var element2 = document.createelement("input");             element2.type = "select";             element2.name = "selectbox[]";             element2.id = "slct";             cell2.appendchild(element2);              var cell3 = row.insertcell(2);             cell3.innerhtml = rowcount + 1;             var element3 = document.createelement("input");             element3.type = "text";             element3.name = "txtbox[]";             element3.id = "txt";             cell3.appendchild(element3);             table.appendchild(cell1);         }     </script>

this table:

<table id = "tab" style="width:500px">     <tr>         <th>date</th>         <th>treatment goal</th>         <th>comment</th>     </tr>     <tr>         <td><input type="date" name="datebox[]" id = "dt"/></td>         <td>             <select name="selectbox[]" id = "slct">             </select>         </td>         <td><input type="text" name="txtbox[]" id = "txt"/></td>     </tr> </table>

i calling function in onclick event of button : 

<input type="button" id="add" value="+" name="add" onclick="addrow('tab')"/>

the html page doesn't respond click event , nothing happens. cannot understand what's going wrong.

working fiddle

the first problem syntax error on line (you didn't close double quote):

element1.name="datebox[];                         ^ missing "

the second problem appending cell table wrong, should appending row:

table.appendchild(row);                   ^ changed row cell
