html - Javascript multiple dropdown in a table -


i trying insert 3 dropdowns on "onclick" event in single row in top bottom sequence,but instead dropdowns inserted sideways.please me new javascript.

code snippet:

function toggle(id) {    var supliers = new array();    var sid = document.getelementbyid(id).checked;    var val = document.getelementbyid(id).value;    supliers.push(val);    if (sid) {      var table = document.getelementbyid("mytable");      document.body.appendchild(table);      (var = 0; < supliers.length; i++) {          var cell = table.insertcell(0);        cell.setattribute("id", "mytr");        cell.innerhtml = "<select  style='width:53px; margin-top: -5px'      name='" + 'drop18' + "' class='smalltext' content='' onchange='fnchange(18);'> " +          "<option value='-1'>select</option>" +          "<option value='7'>yes</option>" +          "<option value='8'>no</option>" +          "</select>";            var cell1 = table.insertcell(1);          cell1.innerhtml = "<select  style='width:53px; margin-top: -10px'   name='" + 'drop18' + "' class='smalltext' content='' onchange='fnchange(18);'> " +          "<option value='-1'>select</option>" +          "<option value='7'>yes</option>" +          "<option value='8'>no</option>" +          "</select>";          var cell2 = table.insertcell(2);          cell2.innerhtml = "<select  style='width:53px; margin-top: -12px'    name='" + 'drop18' + "' class='smalltext' content='' onchange='fnchange(18);'> " +          "<option value='-1'>select</option>" +          "<option value='7'>yes</option>" +          "<option value='8'>no</option>" +          "</select>";        }    }  }
<input type="checkbox" id="suppliera" onclick="toggle(id)">  <input type="checkbox" id="supplierb" onclick="toggle(id)">    <table style="border: 1px solid #000000; height: 250px;">    <tr id="mytable"></tr>  </table>

basically have add them new table rows using insertrow(). suggest moving mytable class table itself. that's result:

function toggle(id) {    var supliers = new array();    var sid = document.getelementbyid(id).checked;    var val = document.getelementbyid(id).value;    supliers.push(val);    if (sid) {      var table = document.getelementbyid("mytable");      var row = table.insertrow(0);      document.body.appendchild(table);      (var = 0; < supliers.length; i++) {          var cell = row.insertcell(0);        cell.setattribute("id", "mytr");        cell.innerhtml = "<select  style='width:53px; margin-top: -5px'      name='" + 'drop18' + "' class='smalltext' content='' onchange='fnchange(18);'> " +          "<option value='-1'>select</option>" +          "<option value='7'>yes</option>" +          "<option value='8'>no</option>" +          "</select>";            var cell1 = row.insertcell(1);          cell1.innerhtml = "<select  style='width:53px; margin-top: -10px'   name='" + 'drop18' + "' class='smalltext' content='' onchange='fnchange(18);'> " +          "<option value='-1'>select</option>" +          "<option value='7'>yes</option>" +          "<option value='8'>no</option>" +          "</select>";          var cell2 = row.insertcell(2);          cell2.innerhtml = "<select  style='width:53px; margin-top: -12px'    name='" + 'drop18' + "' class='smalltext' content='' onchange='fnchange(18);'> " +          "<option value='-1'>select</option>" +          "<option value='7'>yes</option>" +          "<option value='8'>no</option>" +          "</select>";        }    }  }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <input type="checkbox" id="suppliera" onclick="toggle(id)">  <input type="checkbox" id="supplierb" onclick="toggle(id)">  <table id="mytable" style="border: 1px solid #000000; height: 250px;">    <tr></tr>  </table>
