How to access a textbox in a table using ID?

I know this is really simple, but I just can't get it. I want to read the contents of an INPUT textbox with id="myTextbox" within a table cell as shown below:

<table>
<tr>
<td>Textbox</td><td><input type="text" id="myTextbox'></input></td>
</tr>
</table>

thanks

 

var value = document.getElementById('myTextbox').value;

Code (markup):

should work?

 

Meanwhile I'd be questioning why it's in a table much less a table data cell, and why the text next to it isn't in a proper LABEL tag with a FOR attribute.

 

Now you're asking sensible question about noobcode. You should know better
