How can I make a text input mandatory from a drop down selection that is greater than zero?

Make txtBox mandatory when the select value is greater than 0. There will be an alert popup making the text input mandatory.


<option selected="selected" value="0">Select</option>
<option value="1">One</option>
<option value="2">two</option>
<option value="3">three</option>
<option value="4">four</option>

<input type="text" name="txtBox">
