I recently ran across a nifty project called "TiddlyWiki". One of the things that struct me as interesting features from the programming point of view is the fact that it is able to load and save itself to the user's hard drive using Javascript without any kind of server side ...

One of the recent problem that I ran across at work is an easy way to do highlighting for form fields. Of course the best way would be CSS 2 (as shown here) but alas, IE does not support that.
The alternative is JavaScript onFocus and onBlur method. However, one thing ...

For quite some time I have been trying to track down a strange Javascript error. In one of the forms in our application, we have a dynamically generated set of DOM form fields generated on the fly via Javascript. Something like "document.myForm.appendField(field);". The page in question worked just fine in ...

One of the questions that recently came up is how to remove vowels from Hebrew characters in Unicode (or any other similar language). A quick look at Hebrew Unicode chart shows that the vowels are all located between 0x0591 (1425) and 0x05C7 (1479). With this and Javascript's charCodeAt function, it ...

Among the more persistent bugs I have been chasing recently involves a set of interrelated windows. The case in point was a parent window (A) that opened a child window (B) via JavaScript. The child window (B) was set to check whether the parent window (A) is still open before ...

An interesting question that came up today during work was how to wrap text in a table cell that does not contain any line breaks or spaces. For example:
ThisIsCell1
ThisIsCell2
We want the text inside the cells to wrap to the next line instead of extending the table size. There are three ...

(TurboTax now works fine with FireFox on Linux. This post will remain here for historical purposes.)
I have using Intuit's online version of TurboTax for the past few years to file my taxes. However, this was the first year I used it in Linux. Logically, since it is a web based ...

Internet Explorer cannot open the Internet site [url] Operation aborted
After more digging, I ...

Recently I ran across a rather strange error with different browser. Popup windows could be maximized in Opera and Mozilla, but not in IE. The code I was using was as follows (click here to try):
window.open('', '', 'width=200,height=200');
After some digging, I ran across the following snippet in MSDN:
When the sFeatures ...

A recent post at TechDigits about tracking UPS packages via RSS and web services got me thinking if the same is possible via Javascript and the XmlHttpRequest object (in IE and Mozilla). Since Google's Gmail and Google Suggest started using that object, it has become more popular. So after some ...

I filed my first bug with FireFox today: when running self.resizeTo() function in Javascript twice the toolbars on top strech a bit too far. You can try it for yourself below:

One of the more fun things in DHTML is dynamic manipulation of page content. An interesting question that recently came up at work was hiding and displaying a single table row. The solution I came up with is pretty simply - set the CSS STYLE tag of the table row ...

Another rather annoying thing I just ran across is the difference in the implementation of the "typeof" operator in Javascript operating on functions. If you create a function in the parent window, assign it to a property of the parent window, and then pass it to the child window, IE ...

One of the more boring tasks in DHTML is validation of form data and specifically of INPUT and SELECT boxes. Since both have a ".value" property, we can save time and use the same code for checking both:
if(selectBox.value == null || selectBox.value.length == 0)
{ alert('Nothing selected in select box!'); }
else ...

An interesting problem that comes up often is a need to change a part of a web page without reloading the entire page. This is especially true when dynamic content like a list needs to be generated from a database and included in the page. The solution to this is ...
