The HTML <form> tags must be in place in order for Navigator to read button elements. MSIE accepts soft references to form elements, Navigator won't. In the example below, MSIE recognizes the call to it from form jo, and treats the function as though it were preceded by a with statement. The Navigator syntax works with both browsers.

MSIE soft reference allowed

Navigator hard reference required

function show(form) {
jo.jojo.value = "So consider using hard references" }

// soft reference by form name only
// -->
</script>

function show(form) {
document.jo.jojo.value = "So consider using hard references" }
// hard reference includes full hierarchy
// -->
</script>

<form name="jo"><textarea rows="3" name="jojo" cols="20" onFocus="show(this.form)"> Beware!Browsers read thing's differently.</textarea>
