"This" might help. ;-)

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Untitled Document</title>
<script language="javascript">
function textValidate(field) {
if (field.value.length == 0) {
alert("Please enter some text in " + field.name);
return false;
}
}
</script>
</head>
<body>
<form>
Field 1: <input type="text" name="field1" onBlur="textValidate(this);"
/><br />
Field 2: <input type="text" name="field2" onBlur="textValidate(this);"
/><br />
</form>
</body>
</html>
Bear in mind that if you're checking to see if the user entered
anything at all, you also need to handle if they just enter spaces,
which a length check won't catch. I have an "isBlank" function laying
around somewhere that checks both length and checks for space
input--let me know if you're interested in that and I'll dig it up.
