Creating A Hypertext Link

How to create a link to another page. It’s a set tag format like any of the others you have seen so far. Once you learn the format, you can make as many links as you want to any other page you want.

(<A href=”http://www.emilygaston.com” mce_href=”http://www.emilygaston.com”>Click Here For WebPage Authoring</A>)

Here’s What’s Happening

  • A stands for Anchor. It begins the link to another page.
  • HREF stands for Hypertext REFerence. That’s a nice, short way of saying to the browser, “This is where the link is going to go.”
  • http://www.emilygaston.com is the FULL ADDRESS of the link. Also notice that the address has an equal sign in front of it and is enclosed in quotes. Why? Because it’s an attribute of the Anchor tag, a command inside of a command.
  • Where it reads “WebPage Authoring” is where you write the text you want to appear on the page. What is in that space will appear on the page for the viewer to click. So, write something that denotes the link.
  • /A ends the entire link command.

E-Mail Links From Your Page

This is what’s known as a mailto: command. It follows the same coding scheme as the hypertext link above. What this format does is place blue wording on the screen that people can click to send you a piece of e-mail.

Here’s the pattern:

<A HREF=”mailto:sales@emilygaston.com”>Click Here To Write Me</A>

Notice it’s the same format as a link except in a link you write “mailto:” in place of the http:// and your e-mail address in place of the page address. Yes, you still need the </A> tag at the end. Please notice there is NO SPACE between the colon and the e-mail address.

However, please be very careful when using this, for two reasons:

  1. If the person only has an internet based email account, and hasn’t configured an email program on their computer (e.g. if you use Hotmail or Gmail instead of Microsoft Outlook) then it will open their program for email for the first time and try to walk them through setting it up. This isn’t a good idea if they’re new to using computers…
  2. There are now little programs called ‘bots’ which wander round the internet looking for email addresses to send spam  to. If you don’t want to receive them, then one part of this is not publishing your address on your website.  Try using a contact form or  think long and hard before you use a mailto!


Java Security, Is It Pushing The Envelope?

Sun’s web page, ‘Frequently Asked Questions-Applet Security’ http://java.sun.com/sfaq/index.html introduces most of the important activities that Java applets are not allowed to perform.  Sun’s stated goals are to prevent applets from “inspecting or changing files on a client file system” and “using network connections to circumvent file protections or people’s expectations of privacy.”  Of particular interest is Sun’s summary of applet capabilities and the accompanying examples.  The hacker’s challenge is to replace the “NO, applets can’t do that” with Yes, they can, as many times as possible.  As Sun’s examples show, you can’t expect a straightforward approach to the challenges of Java security.  Nevertheless, many security bugs have already been found in Java applets, are you aware of what they are? Hostile Applets can:·       Annoy you with a ‘noisy bear’ who refuses to be quiet·       Bring your browser to a grinding halt·       Make your browser start barking then exit·       Attack your PC with large windows, wasteful calculations, and more noise, effectively excluding you from the console·       Pop-up an untrusted applet window minus the warning and ask you for a login and a password·       Kill all other applets and defend themselves from ThreadDeath·       Forge e-mail·       Obtain your user name·       Exploit your PC to run someone else’s programs and report back the resultsAnd, there are more….So, beware of that little bar at the top of your browser asking you to run a java applet, make sure you know the source or you may be in for a surprise.
