Chapter 16 Using HTML Forms

The following example creates a text area with 5 visible rows that can hold

about 30 characters per row. The result is shown in Figure 16 10.

Enter some HTML:

</font></pre></span>
<span name = "INTRA" style='top:393px; left:293px' class="ft2"><pre><font face='Arial'>Delete this text and replace</font></pre></span>
<span name = "INTRA" style='top:412px; left:293px' class="ft2"><pre><font face='Arial'>with some HTML to validate.</font></pre></span>
<span name = "INTRA" style='top:430px; left:293px' class="ft2"><pre><font face='Arial'>

16.4 Push Buttons

Push buttons are used for two main purposes in HTML forms: to submit

forms and to reset the controls to the values specified in the original HTML.

Browsers that use JavaScript can also use buttons for a third purpose: to trig 

ger arbitrary JavaScript code. 

Traditionally, buttons have been created by the 

INPUT

 element used with a

TYPE

 attribute of 

SUBMIT

, 

RESET

, or 

BUTTON

. In HTML 4.0, the 

BUTTON

 ele 

ment was introduced but is currently supported only by Internet Explorer.

This new element lets you create buttons with multiline labels, images, font

changes, and the like, so is preferred if you are sure your users will all be

using browsers that support it (e.g., in a corporate intranet). Since the ele 

ment is not supported by Netscape, at least as of Netscape version 4.7, for

now you should reserve 

BUTTON

 for intranets that use Internet Explorer

exclusively.
