show/hide formfields

[Pradeep]

I have to show/hide formfields
following functions are correct???

function clickPCSpec()
{
document.forms[0].tag_size.visible = true
document.forms[0].flight_no.visible = false
document.forms[0].gate_value.visible = false

}

function clickECSpec()
{
document.forms[0].tag_size.visible = false
document.forms[0].flight_no.visible = true
document.forms[0].gate_value.visible =true

}

To hide:
document.forms[0].tag_size.style.display = "none";

To show:
document.forms[0].tag_size.style.display = "";

Get more details at HTML DOM Display Property

I also want to show/hide name associated with formfield.For example

The easiest way to show/hide some part of the page (form, field or anything inside) is using CSS.
Put the part you want to show/hide in a div, and change the display-property.

hope it helps.
