Goodies Announcement

The new Beyond HTML Goodies book
is now available!

 

Go beyond the basics
and learn how the pros add and use dynamic HTML features and advanced
JavaScript techniques. Beyond HTML Goodies demonstrates dozens of new and
different features readers can add to their existing Web pages using HTML and
JavaScript. The book starts with simple text and image tips, such as adding a
clock to a Web page or causing text to appear when the mouse moves over an
image. It gradually builds to more complex tricks, including manipulating forms
or working with cookies behind the scenes. Throughout the book, readers enjoy
Joe’s snappy style and “to the point” discussion of each “goody” in the book.

Goodies Thoughts – A Year-end Checklist


It seems unbelievable to me – time simply flies by when you’re
having fun! This year is almost over and it’s time to run down the checklist and
see how much of the "To Do" list was successfully accomplished. If you’re
anything like me then your "To Do" list looks fairly much the same right now as
it did at the beginning of the year! Time just slips by.

My list has actually grown a little this year – apart from anything else, I have
added "Get a new roof" since the three hurricanes we endured here tore the old
one to pieces and my house is still covered with a huge blue tarpaulin!
Contractors, especially the good ones, are in huge demand in this area so I’ll
still have to wait a little.

I did verify all my backup procedures this year though, and made several
improvements. I’ve talked about them quite a lot also, and hopefully have
inspired you to get yours in order also. In case you missed them, you can check
through the newsletter archive (http://www.htmlgoodies.com/letters/index.html)
where you’ll find some of my discussions.

The last item on my list is probably the most important of all, however. It’s
short – just two words; simply: Give Thanks.

A couple of years ago I expressed a few thoughts for the end of a year and the
holiday season that is celebrated in my corner of the world, and I want to
reiterate them this year because they are so applicable in our current times.
Christmas has just passed and to all of you who celebrate this holiday, I hope
yours was wonderful. These thoughts, however apply to us all:

If my audience was ten thousand strong, and represented a cross section of our
global community, only thirty-three hundred of you would be Christian.
Twenty-two hundred of you would be Islamic, fifteen hundred would be Hindu, six
hundred would be Buddhist and four hundred would be Chinese Traditional. Six
hundred more of you would be followers of Sikhism, Juche, Spiritism, Judaism,
Baha’i, Jainism, Shinto, Cao Dai, Tenrikyo, Paganism, Unitarianism,
Rastafarianism, Scientology, Zoroastrianism or another religion, while the
remaining fourteen hundred would either be atheistic or would have no religion
at all (atheistic being those that would say there is no supreme being, and the
others, secular and agnostic, don’t ask the question in the first place and
remain neutral, belief-wise.)

Now this little list of interesting facts didn’t just pop into my head. I wish
my head worked like that! Einstein once said that the greatest knowledge a
person can possess is the address of the local library — he didn’t have the
internet available, obviously! Doing some research on the Web enabled me to
discover these statistics, and a whole lot more about the religions I mentioned
– some of which I hadn’t even heard of before. In fact, everything worth knowing
(and a bunch of facts and information that might not be <grin>) can be found
somewhere on the Web. As the Web grows, so does the pool of human knowledge, and
vice-versa.

Wars are fought all too frequently in the name of religion. It is my belief that
understanding leads to tolerance and peace. Tolerance, by the way, seems to be
an important tenet of all these religions. Knowledge leads to understanding, and
knowledge can be obtained from the World Wide Web.

The World Wide Web comes from you.

So to all you Web Developers, whatever your religion, background or origin, I
wish you wonderful things at this time of the highest holy day of the Christian
religion, and thank you for all the work you do to enlighten me via the
unprecedented, most magnificent, global communications medium of the World Wide
Web. May your creative skills continue to grow, and your knowledge and wisdom
continue to flow.

 

 

Thanks for Reading!

Q & A Goodies


Questions are taken from submissions to our Community Mentors. You can ask a Mentor a question by going to

http://www.htmlgoodies.com/mentors
.

Q. In a web site that I created I made a catalog order form that has a
description of an item, a checkbox to select and a textbox for amount to order.
The code I have is:
<form name="form1" method="post" action="mailto:[email protected]?subject=Catalog
Order Form1" enctype = "text/plain">

<p>
<input type = "hidden" name = "recipient"
value = [email protected] />
<input type = "hidden" name = "subject"
value = "Custodial Order Form1" />

</p>
When the submit button is clicked, it goes to the recepient. But the text/plain
shows items selected and amount but it also shows amounts not selected i.e.:
ven no:1111, item description
AMOUNT=5
AMOUNT=
AMOUNT=
AMOUNT=
(Etc)
All I want is for the items selected be shown and not all of the AMOUNT= not
selected.

A. This is one reason why Server Side languages such as PHP or Perl are
used. They allow you to manipulate the form data before it is emailed out. They
also work better because some people do not have their email clients set up
properly causing the email not to be sent. Having said that though I think your
best bet would be to have two forms – one that gathers the information and a
second with a hidden element that is actually sent. When they click the submit
button the data from the first form is validated, formated and then placed in
the hidden form hidden element to be sent. Here is an example of one that I put
together for someone else:
<html>
<head>
<title>Order Form</title>
<script language="JavaScript">
function calcamt(num)

{
var qtynum=eval("document.myform.qty"+num+".selectedIndex")
var number=eval("document.myform.szeshp"+num+".selectedIndex")
var sizeshape=eval
("document.myform.szeshp"+num+"[number].value.split(‘,’)")

eval("document.myform.price"+num+".value=sizeshape[1] * qtynum")
var pricenum=parseFloat(eval
("document.myform.price"+num+".value"))
var whole = "" + Math.round(pricenum * Math.pow(10, 2));

var decPoint = whole.length – 2;
if(decPoint != 0)
{
result = whole.substring(0, decPoint);
result += ".";
result += whole.substring(decPoint, whole.length);
}
else

{
result = whole;
}
eval("document.myform.price"+num+".value=result")

totalamt()
}

function qtyreset(numa)
{
if(eval("document.myform.item"+numa+".checked"))
{
}
else
{

alert("You must select the item")
return false
}
eval("document.myform.qty"+numa+".selectedIndex=0")
eval("document.myform.price"+numa+".value=’0.00’")

}
function totalamt()
{
var tempamt=0
for(i=0;i<3;i++)
{
var tamt=parseFloat(eval("document.myform.price"+i+".value"))

tempamt=tempamt+tamt

}
var whole = "" + Math.round(tempamt * Math.pow(10, 2));
var decPoint = whole.length – 2;
if(decPoint != 0)
{
result = whole.substring(0, decPoint);

result += ".";
result += whole.substring(decPoint, whole.length);
}
else
{
result = whole;
}
document.myform.totamt.value=result

}
function Formcheck()
{
document.sendit.sdata.value="r Item
Size Qty Pricer"
for(i=0;i<3;i++)
{
if(eval("document.myform.item"+i+".checked"))

{
var fitem=eval("document.myform.item"+i+".value")
var fnum=eval("document.myform.szeshp"+i+".selectedIndex")
var fsize=eval
("document.myform.szeshp"+i+"[fnum].value.split(‘,’)")

var fqtynum=eval("document.myform.qty"+i+".selectedIndex")
var fqty=eval("document.myform.qty"+i+"[fqtynum].value")
var fprice=eval("document.myform.price"+i+".value")

document.sendit.sdata.value+="r"+fitem+" "+fsize[0]
+"@ "+fsize[1]+" each "+fqty+" "+fprice+"r"
}

Q. I am trying to use code from one of the Javascript Tips (41) to
produce a form element that will open a page into a frame. The code works great
for one form element. I want to place 2 form elements next to each other, with
different choices, but I want them to work the same way by opening a page into a
frame. I’ve tried several configurations but I can’t seem to get it to work. If
I duplicate the code, but change the form name and select name, only one works.
(code sample provided)

A. I think you will find this example a little more efficient. It uses
the onChange event in the select tag to perform the function. At the same time
it passes the link in the value tag of the option statement to the function.
Just remember to name your dropdowns differently.
<html>
<head>

<title>Drop Down Test</title>
<script language="javascript">
function LinkUp(linkid)
{
if(linkid!="")
{parent.frames[2].location=linkid}
}

</script>
</head>
<body bgcolor="lightgreen">
<form name="DropDown">
<select name="DDlinksa" onchange="LinkUp(this.options [this.selectedIndex].value)">
<option selected value="">Choose a Link

<option value="http://www.requestcode.com"> Request Code</option>

</select>
<select name="DDlinksb" onchange="LinkUp(this.options [this.selectedIndex].value)">
<option selected value="">Choose a Link
<option value="http://www.htmlgoodies.com"> HTML Goodies</option>

<option value="http://www.wsabstract.com"> Website
Abstraction</option>
<option value="http://www.requestcode.com"> Request Code</option>
</select>
</form>

</body>
</html>

Q. I have a Feedback form and have managed to get it to open the e-mail
programme in order for the viewer to e-mail their feedback to me, but the
problem I am having is to get the SUBJECT line to state "FEEDBACK".

A. If you want the subject line to be filled automatically you need to
add "?subject=FEEDBACK" to the MAILTO link like this:

mailto:[email protected]_Site.com?subject=FEEDBACK
Change FEEDBACK to anything else if you want something different!

Q. Could you please tell me how to link one page to a specific point on
another page? Also, how do I link the top of one page to the bottom of the same
page?

A. If you want to link to a spot on a particular page you can use the
NAME ANCHOR. For instance if you had a long page and wanted to give the user an
easy way to get back to the top after reading the article you would place this
in the HTML near the top after the <BODY> tag:

<a name="top">
At the end of the article you would place this code:
<a href="#top">TOP</a>
That creates a link to the top of the page. If you want a link to a certain area
on another page it is done in a similar way. On the page you want to link to you
place the NAME ANCHOR in the spot on the page you want to jump to:
<a href="jump">Jump Here</a>

On the page you are coming from, the link would look like this:
<a href="#jump">Click here to Jump</a>
Here is the tutorial from the HTMLGoodies site:

On this day in…
 

1932 Radio City Music Hall Opened

A creation of billionaire John D. Rockefeller, the Radio City Music
Hall was opened on this day in 1932. Since that day, more than 300
million people (including yours truly) have been there to enjoy
shows, concerts, movies and special events. Despite being in the
middle of the Great Depression, thousands of people came to the
opening event. The hall is a magnificent Art Deco theater, a "palace
for the people", designed by Donald Deskey, and built by Rockefeller
in partnership with the Radio Corporation of America (RCA). At its
heart is the Great Stage, which is 60 feet by 100 feet and
incorporated sophisticated hydraulic elevators for dramatic staging
effects. Many of the original hydraulics are still in use today.
More than 700 films have premiered at Radio City Music Hall. Its
"Christmas Spectacular", which debuted in 1933, entertains more than
a million people each year, and includes the famous high-kicking
precision dance troupe, the Rockettes. It is still the largest
theater in the world.
