Just about all browsers have a find on page option in the menu and so adding an equivalent option using JavaScript may not appear all that useful. It doesn’t work completely the same way as the built in ones do though since it uses a separate browser window rather than a dialog box and therefore doesn’t need to be closed in order to continue interacting with the page.
The best ways of passing values from one page to another require server side scripting. That way they work for everyone and not just those with JavaScript enabled. There are a number of different situations where you need to pass values and this article looks at several situations and how to handle them with two different scripting languages.
Sometimes you have a piece of content that you want to display in a number of different web pages and you want it to look the same in all the pages regardless of how the rest of the page looks. In this article we look at how you can write the stylesheet commands for a given piece of content in such a way as to minimise the possibility that it will interfere with the rest of the page.
The one browser that has always insisted on doing things its own way rather than following the standards is Internet Explorer (this is perhaps because for a number of years IE6 was so popular that it effectively was the standard). Now that IE only has 50% of the market you need your web pages to work on standards compliant browsers as well as IE and so you need to also be aware of the quirks in how IE works. One of these quirks is hasLayout and in this article we look at how to code your stylesheet so that it works correctly in both standards compliant browsers and in IE.

Object Oriented Programming languages make developing programs to run on multiple operating systems much easier. All you need is a class library of common functions that has a separate version you can link in for each of the operating systems you want to support where the public interface to the multiple copies of those classes is the same for each platform. It is then a simple matter of linking in the appropriate verion of the library for each operating system.
When is text not text? When it is a part of an image. As far as most computer programs are concerned text and images are two completely different things and any text that you have placed inside an image is just a part of that image and can’t be read by the program. There are a few exceptions to this all of which involve optical character recognition.
For anyone still using a dialup connection to connect to the internet, it may not always be convenient to read all your emails during the one session online and it may not be worth dialing back in just to see the rest of your emails. Fortunately most email clients download all your emails while you are connected and allow you to read them whenever you like without having to be connected to do so.
