In javascript, how to add new rows in a table using document.createElement()?

Question

I want to have a table and a textbox, when I input some value for the textbox then click the button, the value will be added into a table. I wrote the code but it doesn't run. Please help me to find out what wrong with the code below.

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<script>
function send() {
        tbl=document.getElementById("idtable");
        tr = document.createElement("tr");
        td1 = document.createElement("td");
        td2 = document.createElement("td");
        name = document.getElementById("txtname").value;
        email = document.getElementById("txtemail").value;
        td1.innerText=name;
        td2.innerText=email;
        tr.appendChild(td1);
        tr.appendChild(td2);
        tbl.appendChild(tr);
}
</script>
</head>
<body>
<input type="text" id="txtname" name="txtname"/> <br/><br/>
<input type="text" id="txtemail" name="txtemail"/>
<p> <input type="button" value="Send" onclick="send()"/>
<table id="idtable" border="1">
<tr><td>Name</td> 
 <td>Email</td>
</tr>
</table>
</body>
</html>

Can you be more specific than "it doesn't work" ? What is wrong when running this code on your computer ? — 3Dos

try this code:

function send(){
   var table=document.getElementById("table");
   name=document.getElementById("txtname").value;
   email=document.getElementById("txtemail").value;
   table.innerHTML+=('<tr><td>'+name+'</td><td>'+email+'</td></tr>')
}

<input id="txtname" name="txtname"/> <br/>
<input id="txtemail" name="txtemail"/> <br/>
<input type="button" value="Send" onclick="send()"/><br/>
<table id="table" border="1">
   <tr><td>Name</td><td>Email</td></tr>
</table>
