# Option One
<script type="text/javascript">
  $(document).ready(function() {
    $("input:text").each(function () {
      var v = this.value; // store default value
      $(this).blur(function () {
        if (this.value.length == 0) this.value = v; // if input is empty, reset value to default 
      })
      .focus(function () {
        this.value = ""; // when input is focused, clear its contents
      });
    });
  });
</script>

# Option Two
<input type="text" onfocus="if(this.value == 'value') { this.value = ''; }" value="value" />
