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 - Safe and Secure


Doesn't that title sound cozy?!! Beware, however, because as you probably know by now, when you hear those words in this business it's usually the last thing you actually are! There are some things that you can do to help build security on the Internet, however, and today I'm exploring the costs of one of them.

That one is the secure web site. Any time you involve yourself in financial transactions on the web, whether as a buyer or as a seller, or even if you are simply giving out or collecting personal information beyond a name and address, you need to be sure that the web site is securely encrypted. I am sure you, as a buyer, are aware of the tell-tale key or padlock (depending on your browser) that is displayed when you visit a secure site. It is something you should definitely be double checking before sending in your information. It tells you that the site's server is talking with your browser with encrypted messages so that only the people who should be able to read your info can. If you're using Internet Explorer it's displayed in the status bar along the bottom (if you don't see the status bar, click "View"/"Status Bar".) Try going to a secure site and double clicking the padlock -- take a look at what it represents.

If you're building a fairly simple site that is going to involve collecting money, then one option open to you is to use a service like Paypal (http://www.Paypal.com) Paypal is now a subsidiary of Ebay, which has some great advantages if you want to sell your products through an Ebay store or in the Ebay auctions themselves. There are hooks from each of their services into the others that make life a breeze. You can also use Paypal to process your transactions from your own site. They provide you with all the code you need and with instructions for its use. When you consider the hassle (and sometimes the expense) involved in setting up a merchant account to receive credit card payments, along with the issue of the secure site itself, Paypal can make a lot of sense (cents too, maybe!)

When your site is more complicated than would suit Paypal, or when you are simply going to collect personal information that shouldn't be broadcast (I think of unsecured web transactions as though they were on a CB radio,) your only option is to set up a secure web site. To do this you are going to need an SSL (Secure Sockets Layer) certificate. This is a certificate that is attached to your site and is used in the negotiation of a secure, encrypted connection to, among other things, verify the identity of the site. Unless you run your own server, you are going to need the assistance of your hosting company in setting up your certificate, but you should in any case be able to choose your certificate vendor.

For the certificate to work in the desired fashion, without giving the site visitor any error messages, your certificate needs to be issued be a certificate authority who is already recognized by your browser. This means, basically, that you can't issue your own certificate but have to go to a certificate vendor. The famous vendors include Verisign, Thawte, Geotrust and the like, but there are others.

These vendors charge for issuing their certificates. A basic 128 bit certificate good for one year from Verisign is $349.00, from Thawte it's $449.00 and from Geotrust it's $159.00 -- a few moolahs no matter who you choose! There may be a business reason for choosing one of these well known companies, but if you are simply wishing to set up an encrypted, secure site for typical purposes you can save a few dollars by going to a company called XRampSSL (http://www.xrampssl.com)

XRampSSL charge $89.95 for one year. Buy two and get one free! Years, that is. For $179.90 you get three years -- the equivalent of $60 per year -- much better. I have spoken with these guys and checked out their product. It's the real deal - it works just fine. If you need to set up a secure site for any of the purposes I've discussed here, I suggest you check 'em out!
 

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.  I'm making a form that will be used by users to apply for a job. I want to make sure that the form will not be submitted if they type text into the "phone number" text box. All my attempts have failed, Could you give me an idea of what is going on?

</SCRIPT>

A.(1) Take a look at the HTMLGoodies Javascript Primer #29 - Putting It All Together: Form Field Validation located at
http://www.htmlgoodies.com/primers/jsp/hgjsp_29.html
The example includes the validation of a numeric zip code that should be easy enough to adapt to a phone number. It will also shorten your script considerably.

A.(2) You could also use the method isNaN (is-Not-a-Number) to insure that only numbers are entered. It goes something like this:
if(isNaN(document.job.phone.value))
{alert("Numbers only please!")}





Q. I have recently made an e-mail form with the help of the tutorial on the site, and my form is made up entirely of text boxes. However, I find that the
text boxes are ugly.. I would like the borders of them to be a different colour, so they do not have that "greay shadow" look. I know it is possible to change the colour of them, as I have seen it done on another website, but how can I do it on mine?

A. The easiest way to do it is to set up a style for the "input" in you style sheet, since you are only using text boxes. The following will also apply to any radio buttons or checkboxes that may be in the form. If you add them later, you may want to set up a class. But for now, add this to your style
sheet:
input { border: 1px solid black; }
You can use change the pixel size, or switch from solid to dashed. For colors, you can use the text names that are available, or the hexidecimal (#000000).




Q. How do I make a link from a popup window close the popup window and link back to a page of the main web site?

A. To refer back to the window that opened the popup you would use the term "opener". I would suggest that you create a function in your popup to load the page into the main window and then close the popup. The function could look like this:
function LoadPage(linkid)
{
opener.location.href=linkid
self.close()
}
You can then call this function and pass the page you want to load into the "opener" window as a value like this:
<a HREF="#" onClick="LoadPage('mypage.html')">Click Me</a>
or:
<a HREF="javascript:LoadPage('mypage.html')">Click Me</a>
The second example might be better because IE5.0 has a problem when you use the "#" sign to void the link. You can also reference function in the "opener" window from the popup by prefacing the function name with the term "opener" like this:
opener.function_name()
As you can see you can reference just about anything in the main window as long as you preface it with "opener".





Q. Is there a way to have something other than a button do this job?
<FORM>
<INPUT TYPE="button" Value="Change Three Frames at Once"
onClick="parent.frames[1].location='zippy5.html';
parent.frames[2].location='zippy6.html';
parent.frames[3].location='zippy7.html';">
</FORM>
I would like to have a blue underlined word do the same thing the button does, to save vertical space in a clickable list arrangement.

A. You can use a text link like so:
<A HREF="#" onClick="parent.frames[1].location='zippy5.html';
parent.frames[2].location='zippy6.html';
parent.frames[3].location='zippy7.html';">Click Here</A>




Q. Recently we have discovered that someone has taken pictures from several of our web sites and is using them on his site to advertise. I know there
are JAVA scripts to disable right clicks and make this sort of piracy more difficult with Explorer. Is there ANY way to stop this if the person uses Netscape?

A. Keep in mind that the images on your site cannot be 100% protected from people taking them. There is a way around the "no right click" script. But it might slow them down if they don't want to go through the extra effort. I have tested this script in Netscape Navigator 4.7 and it works. I think it should work in most of the browsers but I am not sure as to which ones.
Place the folowing code between the <HEAD></HEAD> tags of your HTML code.
<script language="JavaScript">
<!--
/*
No rightclick script v.2.5
(c) 1998 barts1000
barts1000@aol.com
Don't delete this header!
*/
var message="Sorry, that function is disabled.\n
This Page Copyrighted and\n
Images and Text protected!\n
ALL RIGHTS RESERVED";
// Don't edit below!
function click(e) {
if (document.all) {
if (event.button == 2) {
alert(message);
return false;
}
}
if (document.layers) {
if (e.which == 3) {
alert(message);
return false;
}
}
}
if (document.layers) {
document.captureEvents(Event.MOUSEDOWN);
}
document.onmousedown=click;
// -->
</script>

And Remember This . . .


On this day in...

1941 Genocide Begins at Babi Yar

On this day in 1941 30,000 Jewish men, women and children lost their lives in a massacre outside Kiev in the Ukraine. Kiev had been taken by the Nazis on September 19. Adolph Hitler ordered the deaths of all Jews and Soviet Officials there and the order was carried out by SS personnel. The 30,000 were marched in groups to a ravine on the outskirts of the city. There they were ordered to strip naked and were then machine gunned into the ravine. By the end of the next day, 34,000 had perished as the dead and wounded alike were buried in rocks and dirt. The Babi Yar massacre marks the beginning of the Holocaust.


Today was also the day that: in 1829 Scotland Yard and London's Metropolitan Police Force were established; 1895 Louis Pasteur died; 1915 275 die in a hurricane in the Mississippi Delta; 1918 the allies break through the Hindenburg line; 1944 Soviet troops invade Yugoslavia; 1953 the Milton Berle Show premiered; 1962 the first Canadian satellite, Alouette I, was launched; 1963 The Rolling Stones start their first tour as the opening act for Bo Didley and the Everly Brothers; 1977 the Soviet space station Salyut 6 was launched into orbit; 1982 cyanide laced Tylenol killed seven people in Chicago (never solved and "copycats" still sporadically occur, mostly in the Chicago area - incidence has been reduced by tamper-proof packaging); 1987 Henry Ford II died in Detroit; 1990 Washington National Cathedral construction was completed (after 83 years of work);

Born today were: in 1758 Admiral Lord Horatio Nelson; 1901 Italian nuclear physicist Enrico Fermi; 1907 singer/actor Gene Autry; 1908 actress Greer Garson; 1916 actor Trevor Howard; 1929 actor/comedian Bob Newhart; 1931 actress Anita Ekberg; 1935 singer Jerry Lee Lewis; 1939 actor Larry Linville (MASH - Frank Burns); 1942 violinist Jean-Luc Ponty; 1942 actress Madeline Kahn; 1942 US astronaut William (Bill) Nelson; 1943 Polish Solidaritet leader Lech Walesa; 1948 sportscaster Bryant Gumbel;
