Chapter 14: Forms Continued
Pull Down and Scrolling Lists
The next type of input is a Pull Down List. With this type you use <SELECT> instead of <INPUT> and it has a closing tag.
<SELECT>
</SELECT>
Don't forget to give it a name.
<SELECT NAME="POSITION">
</SELECT>
Next add a few options.
<SELECT NAME="POSITION">
<OPTION>Powerbuilder Developer
<OPTION>Database Administrator
<OPTION>None of the above
</SELECT>
And give each <OPTION> a VALUE.
<SELECT NAME="POSITION">
<OPTION VALUE="PB">Powerbuilder Developer
<OPTION VALUE="DBA">Database Administrator
<OPTION VALUE="NOTA">None of the above
</SELECT>
The default option is the one that is listed first.
We can specify a default other than the first option in the list.
<SELECT NAME="POSITION">
<OPTION VALUE="PB">Powerbuilder Developer
<OPTION VALUE="DBA" SELECTED>Database Administrator
<OPTION VALUE="NOTA">None of the above
</SELECT>
A Scrolling List is very similar in construction to a Pull Down List.
We'll add a few more options first. Then, all we do to turn it into a Scrolling List is add a SIZE attribute to the <SELECT> tag.
<SELECT NAME="POSITION" SIZE=4>
<OPTION VALUE="PB">Powerbuilder Developer
<OPTION VALUE="DBA">Database Administrator
<OPTION VALUE="VB">Visual Basic Developer
<OPTION VALUE="ADMIN">Administration staff
<OPTION VALUE="JANITOR">Janitor
<OPTION VALUE="NOTA">None of the above
</SELECT>
The SIZE is simply how many options show in the window.
Again, the default value is the first <OPTION>, and again we can change that by selecting one.
<SELECT NAME="POSITION" SIZE=4>
<OPTION VALUE="PB">Powerbuilder Developer
<OPTION VALUE="DBA" SELECTED>Database Administrator
<OPTION VALUE="VB">Visual Basic Developer
<OPTION VALUE="ADMIN">Administration staff
<OPTION VALUE="JANITOR">Janitor
<OPTION VALUE="NOTA">None of the above
</SELECT>
Textarea
A very useful type of input is <TEXTAREA>.
<TEXTAREA NAME="COMMENTS">
</TEXTAREA>
You control the size of the box like so...
<TEXTAREA NAME="COMMENTS" ROWS=6 COLS=50>
</TEXTAREA>
ROWS is the height, COLS is the width.
A good attribute to include in <TEXTAREA> is WRAP. Some browsers do not understand it, but if that's the case, they will just ignore it.
Go ahead and type in the boxes...
<TEXTAREA NAME="COMMENTS" ROWS=3 COLS=30 WRAP=VIRTUAL>
</TEXTAREA>
WRAP=VIRTUAL means that the text in the box wraps, but it is sent as one long continuous string.
<TEXTAREA NAME="COMMENTS" ROWS=3 COLS=30 WRAP=PHYSICAL>
</TEXTAREA>
WRAP=PHYSICAL means that the text in the box wraps, and it is sent that way too.
<TEXTAREA NAME="COMMENTS" ROWS=3 COLS=30 WRAP=OFF>
</TEXTAREA>
This is the default.
WRAP=OFF means that the text in the box does not wrap, but it is sent exactly the way it was typed in (like the little man a few textareas back).
Your own HTML page...
Open the page "feedback.htm" in Notepad, and add the following (the blue text is what to add).
<html>
<body background="bgnd.gif">
<center><h1>Feedback Form</h1></center>
<br>
<form>
<b>My name is: </b><input type=text name="name">
<p>
<b>I work as a:</b><br>
.
.
</p>
<p>
<b>When it comes to web browsers:</b><br>

<select name="Rating">
<option value="Wow">Wow! How did you do it?
<option value="good">Really good
<option value="interesting">Interesting
<option value="hmmm">Hmmm - seen better
<option value="tryagain">Try again bud!
</select>
</p>
<p>

<textarea name="comments" rows="6" cols="50" wrap="physical">
</textarea>
</p>
