    Don’t use “name” as an ID, but use getElementById.

    var value = document.getElementById("foo").value;

    But you should use a form :

    <form name="myform" action="?" method="get" onsubmit="return CheckInfos(this)">
  <input type="text" name="foo" />
  <input type="submit" value="test"/>
</form>

<script>
function CheckInfos(form) {
  if (form.elements.foo.value == "") {
     alert("error");
  }

  return false;
}
</script>
