Suggest a form valueTag(s): Form
When you click inside the text box, you will see that the text disappears.
<script language="Javascript"> <!-- function doClear(theText) { if (theText.value == theText.defaultValue) { theText.value = "" } } //--> </script> <form> <input type="text" size=15 value="Try it here" onFocus="doClear(this)"> </form>
Or you can keep (and select) the default value :
<script language="Javascript"> <!-- function doSelect(theText) { if (theText.value == theText.defaultValue) { theText.select(); } } //--> </script> <input type="text" value="Try it here" onfocus="doSelect(this)">
