innerHTML

I have few troubles about innerHTML

1, In Firefox, it can't copy the INPUT text object's value attribute and SELECT object's selectedIndex property.

2, Style sheet won't be copied from one window to the other window.

3, In the TEXTAREA, I have one space and one non-break space(nbsp). Then, I assign this TEXTAREA value into an object innerHTML, but one space left.

Dynamic HTML creation

I would like to compare the performance of dynamic content creation between document.createElement and innerHTML, because I were looking how to improve the very large table rendering.

I found an very interesting article :

JavaScript optimization: Adding DOM elements to document

This is definitely worth to give it a trial. I am somehow to prefer to use innHTML, because it's easy to trace down the code. But, sometimes, DOM manipulation can't be avoided.

Java SE Performance at a Glance


What is SUN's promotion for Java SE6?

This page http://java.sun.com/javase/technologies/performance.jsp is so old. Today, I see last article posted December 2005 and only Java 5 mentioned in this page.

This Much I Know - » inline-block in FireFox

This Much I Know - » inline-block in FireFox

Just learn Firefox display style -moz-inline-box and -moz-inline-block.

What's the difference?
For two nesting DIVs.

When outside DIV is "-moz-inline-box" and inside DIV is "-moz-inlineblock", then
"-moz-inline-box" allows to expand the width if content length overflow.

When both outside and inside DIV are "-moz-inline-block", then
content will be overlay if inside DIV content length overflow.

Charging Batteries without Wires

New MIT research reveals a way to send wireless energy to mobile phones and laptops.

In page 2,
Using the electric field would pose a health risk, and would be better employed in applications in which people aren't nearby, he says. Conversely, using the magnetic field would be much safer and could be implemented just as easily. "I can't think of any reason to worry [about health concerns]," he says, "but people will."

As technology improvement, everything are getting handy, but doesn't mean people are getting healthy. Got to make some search how electric field and magnetic field affect to people health.

New Motor Trend

The new Motor Trend web site is much better than before. It's more like an enterprise now. Previously, the page was design for small screen and had no enough space for padding.

window.console

I tried to control BUTTON size with relative size, like

BUTTON {display:block; text-align:center; width:2em; height:1.5em; padding:0;}

However, Safari give me a bigger size.
So, I tried to size down from javascript.

if (window.console) { //safari
document.writeln("<style type="'text/css'">");
document.writeln(".ccActions BUTTON {width:1.5em; height:1em;margin-bottom:2px;}");
document.writeln("</style>");

}


Unfortunately, my Firefox 2 understood window.console. I
was surprised, but I didn't see it in the mozilla DOM reference.

But, I didn't have this problem in my new laptop's FF2. So, I looked at my extension. I disabled Firebug, then I found my script was good again.

So to be safe, I change my Safari condition as
if (window.console && window.console.log) //safari

Another Notes :
When I tried
if (window.console && window.console.log()) //safari
Safari crashed. Despite Safari is rarely crashed, but I still don't like.

Resume my blog

Previously, I found blogger only kept my one year blog. I was upset and stop to post.

Now, I see my early post shown again. It's time to resume.

Widgets, BitTorrent, content blocking: Introducing Opera 9 Beta

Play new Opera 9 for a day. There are a lot of imporvement in the style sheet, but I still see few problem.

The interesting thing is when I visit youtube. Usually in Firefox, I click "Home" tab to go to the front page and I can see "Recently Viewed" differently each time. But, when I try Opera 9, those recently viewed thumbnails are never change.

FIELDSET/TABLE Padding

Another headache about FIELDSET. I have two FIELDSETs side by side ( left and right).
The left side is for Work Address and right side is for Home Address. They are almost same except Organization and Position in Work Address.

I try to make there two FIELDSETs in the same height with style sheet height:30em, but Firefox gets more space in the bottom.

Finally, I find that IE will have margin on the top/bottom of each INPUT text field. So far, I have no luck to remove the extra margin on the top/bottom of text field.

CLC-4-TTS and Fire Vox

Safari contentEditable

Interested move -- Safari is going to use contentEditable behavior to do textfield. It's definite to benefit css. My immediate question : does this apply to textarea, too? And, is this really compatible since people were talking about range issue in the contentEditable?

Actually, my major concern is when scrollbar will be always displayed correctly in the textarea.
Right now, if textarea is small, the up/down arrow won't display.

Safari always claim great feature. When I examine it, it's kind of crippled.

Suggestion to Google toolbar

So far, I can't a spell check extension for Firefox in windows. The spell check Google toolbar may be helpful. But, I think, it can be more helpful if the spell check function is the context menu. Some of my web forms are on the pop up window.

Flash and Flex

Whatcott said the Adobe platform supports things that AJAX does not support, such as programmable audio, video, vector graphics, synchronous publish/subscribe data connectivity, offline data storage and cross-domain data access.

Constantly, I use iframe to add other domain content; however, there is always security issues and can't expand iframe to content max size. Just read an article from eweek and put a quote on the top. Is flash my solution?

Safari Compatibility Hit List

The WebKit Open Source Project post compatibility hit list today. Usually, using Safari to look at a pure thml page is great -- nice and neat font. But, when looking at more complicated pages, safari is like the secondary browser. It lacks HTML editor and a lot of JavaScript issues.

Besides standard compatibility compliance, I hope Safari can catch up usability.

Acrobat User Community

My first throught about www.acrobatusrs.com is message board. People can post question to get help from web community. But, when I vist the site. I see blogs and some other learngin materials, not message board. Anyway, this is great move for adobe.

I have mixed feeling about PDF file. I would like people to send me PDF file instead of MS word file, but in the web, I will try not to open any PDF file. I think Acrobat reader is a monster as many reasons.

Web-based Intranet and Internet Information and Applications (1194.22)

Sestion 508

(n) When electronic forms are designed to be completed on-line, the form shall allow people using assistive technology to access the information, field elements, and functionality required for completion and submission of the form, including all directions and cues.

There is a grey area on checkbox and radio button. Where do I put LABEL.

For example :

Accessories :

[ ] Printer

[ ] Monitor

[ ] Keyboard

[ ] Mouse

I believe each checkbox need to associate a LABEL with text on the right side.

Safari and Textarea

Safari try to take some advantage native UI; unfortunately, the TEXTAREA is not quite right.

1, The scrollbar up/down arrow can't be shown, if rows less than 4.
2, Try to control textarea height, but scrollHeight is fixed number and never be changed.

JavaScript Graphics Development

The other day, I were thinking how to draw fourier wave by using javascript canvas. At that moment, my assumption was that as long as I could figure out how to draw sin and cos, then I could do that.

Now, I just looked at the site http://davidbetz.net/graphics/ how to draw sin and cos. To draw a wave, it draw pixel by pixel. In this case, I need to work on my math how to calculate intrgral, then draw a fourier wave.

IEBlog : For the SELECT few...

First, I am wondering how many peoples are working on IE?

As to SELECT (MS combobox), it's most buggy object in IE.

Now, they have windowless fix. The other problems I have :

1, OPTION style sheet support.

2, If a LABEL object is associated with SELECT. Click this LABEL, then the related SELECT get focus. Unfortunately, the SELECT always select the first item.

3, Use style sheet to set a small size to SELECT object. When drop down pop up, the longer item OPTIONs will be cut off.

Firefox innerText

I just implemented a method to get innerText. It's for a complicated document.


function ccGetMZInnerText(element) {

if (element.hasChildNodes()) {

var displayType = window.getComputedStyle(element,null).getPropertyValue("display");
if (displayType != null && displayType!="none") {
for (var i = 0; i <>
if (element.tagName=="P") innerText = "\n" + innerText;
innerText = innerText + ccGetMZInnerText( element.childNodes[i] );
}
if (displayType!="inline") innerText = innerText + "\n";
}

} else {

if ( element.nodeType == 3 ) {// text
innerText = innerText + ccTextCorrection(element.nodeValue);
} else if (element.nodeType == 1) { //object
var displayType = window.getComputedStyle(element,null).getPropertyValue("display");
if (displayType == null || displayType=="none") {
} else if (displayType=="inline") {
innerText = innerText + ccTextCorrection(element.textContent);
if (element.tagName=="BR") innerText = innerText + "\n";
} else {
innerText = innerText + ccTextCorrection(element.textContent) + "\n";
}
}

}

return innerText;

}

function ccTextCorrection(fooString) { //replace to blank, and remove line break.
return fooString.replace(/ /g, " ").replace(/\n/g, "").replace(/\r/g, "");
