4310	Problem ... I want to print a series of numbered forms Just occasionally, we come across problems that sound easy but end up looking like they need specialised software that's going to cost money to buy for a single use, before we evel look at the time to learn into it. One such problem has cropped up today in that I want to print out a series of sequence ...	2014-10-07
4277	Sending a message to the server and changing text on a page when a button is pressed Scenario ... * I wish to provide a button on my page that signals when it's pressed back to the server * I wish the server to log the button press (a vote, perhaps) but not refresh the page * I wish to change the text on the page to give visual feedback that the button has been pressed Easy enough, ...	2014-05-26
3128	How does your browser find out about itself? • Does this browser accept Cookies? • Does this browser accept Flash? • What processor chip type is in the computer hosting this browser? • Will this browser run Java Applets? • How wide is my window? The answer ... if Javascript is enabled, which it usually is these days, is ...	2011-01-12
2628	An example of an injection attack using Javascript Delegates sometimes ask me what an "injection attack" is, and for examples. I came across a really good example this morning on (oops!) one of our own pages - it's now fixed, but I'm documenting here and showing you what was happening so that you can learn from it. Visiting one of the most popular pages ...	2010-02-11
411	Javascript examples (some PHP and MySQL too) If you're looking for some simple examples in Javascript (alert window, checking the value in a field, one select box that depends on another, checking window width and browser type), etc, I've just posted some short pieces of code that I wrote yesterday to our client side technology area. So often I ...	2009-09-06
2390	Dynamic / changing images on your web page There are a number of different ways to provide dynamic (changing) images within a web page ... but as they're mostly client side technology based, they're not something I commonly get involved in. However, just yesterday I was thinking of using exactly such a dynamic image in my post telling you about ...	2009-09-01
1814	Javascript/HTML example, dynamic server monitor There are times I want to keep an eye on our servers, but I don't really want to redraw my whole browser window (or even a frame!) to do it. So I've written a Javascript application to run in my browser (source code here) that calls up a tiny piece of PHP on the server (source code here) and replaces ...	2008-09-28
1812	Starting Ajax - easy example of browser calling up server data Ajax (Asynchronous Javascript and XML) provides a very neat way for a web page that's displayed on a browser to interact with a web server and replace just part of the page content without the need to reload the whole HTML document or Frame. It works like this: 1. The original document called up from ...	2008-09-28
1813	Ajax - going Asyncronous and what it means This is the second part of an "easy Ajax" series - for the first installment [link here]. In the first installment, I showed you a "bare bones" example in which Javascript on a browser called up a web service to change information being displayed dynmaically - but I couldn't reall call it Ajax (more ...	2008-09-28
1749	Using server side and client side programming together I was back for first principles this morning for a delegate who - though very much an experienced programmer - is new to web work and HTML, and I put together a series of demonstrations using various web components ... 1. A straightforward HTML page, including document definition, a head and a body ...	2008-08-11
1681	Adding a button to a web page to print the page How to add a "print me" button on your web page which (err) lets you print your web page ;-) <form> <input type=button value="Print me!" onClick="javascript:window.print()"> </form> Here it is to try out: ...	2008-06-18 (short)
1322	Flash - is it available to your web page? We're "flash enabling" some of our web pages .... while at the same time retaining the default pages, seemlessly, for anyone who's not got Flash installed or has an old version. I've been doing some research on the subject and ... separating out the wood from the trees, I'll present you a link to the ...	2007-08-26
522	Javascript events - a good example Complete a form, submit it to the server, get the response page back. Typical web form filling which I sometimes describe as "batchlets" - almost back to the old style batch processing where you make up a complete job and submit it exactly has was doing in the 1970s - except that now it takes 120 ms ...	2006-06-05
