How do you add textbox when options is selected using javascript?

The best way to add a test box based on an option chosen from a select box is to modify the DOM to show the element. You can accomplish this by adding the text box to the DOM when the option is selected, or by having it already there, but hidden, until the option is selected.
Here is some sample code to show the text box only when Option 7 is chosen. Feel free to modify it to suit your needs:
<select onchange="if (this.value 7) { document.getElementById('textbox1').display = 'inline'; } else { document.getElementById('textbox1').display = 'none'; }">
<input type="text" id="textbox1" name="textbox1" style="display: none;">
Both of these methods can also be used by creating a JavaScript function to handle the actual procedure, and the onchange attribute can simply call that function. You can use arguments to the function to encapsulate and reuse the code for other elements on your page.
