Example 10.6:
Getting the forms Array's length Property
Here's the first form in the document (it doesn't do anything):
Here's the second form. The buttons use different methods of referring to the form when getting the length property:
This is the script we used in the HEAD:
<![CDATA[
<SCRIPT LANGUAGE="JAVASCRIPT">
<!--
function FormLengthArray() {
alert("The form has " + document.forms[1].length + " elements.")
}
function FormLengthName() {
alert("The form has " + document.secondForm.length + " elements.")
}
//-->
</script>
]]>
Later in the page we have these buttons (in the second form):
<![CDATA[
<FORM NAME="secondForm">
<INPUT TYPE="button" NAME="But1" value="Display the form length (the number of elements in the form) using the forms array" onclick="FormLengthArray()"><B>
<INPUT TYPE="button" NAME="But2" value="Display the length using the form name" onclick="FormLengthName()">
</FORM>
]]>
