Chapter 16 Using HTML Forms

will want to use the 

POST

 method when using a password field so that a

bystander cannot read the unobscured password from the URL display at the

top of the browser. 

Core Approach

To protect the user's privacy, always use 

POST

 when creating forms with 

password fields.

NAME, VALUE, SIZE, MAXLENGTH, ONCHANGE, 

ONSELECT, ONFOCUS, ONBLUR, ONKEYDOWN, ONKEY 

PRESS, and ONKEYUP

Attributes for password fields are used in exactly the same manner as 

with textfields.

HTML Element:

<span name = "INTRA" style='top:873px; left:532px' class="ft0"><pre><font face='Arial'><b>ROWS=xxx COLS=yyy> ... </b></font></pre></span>
<span name = "INTRA" style='top:893px; left:435px' class="ft0"><pre><font face='Arial'><b>

Attributes:

The 

TEXTAREA

 element creates a multiline text area; see Figure 16 10. There

is no 

VALUE

 attribute; instead, text between the start and end tags is used as

the initial contents of the text area. The initial text between

 is treated similarly to text inside the now obsolete

 ele 

ment. That is, white space in this initial text is maintained and HTML

markup between the start and end tags is taken literally, except for character

entities such as
