The possible value are: “slow”, “normal”, or “fast”, but what does that mean? I had to dig into the source code to find out.

Fast: 200 ms
Normal: 400 ms (default)
Slow: 600 ms

That may be due to the fact that IE has sooo many problems. On this occasion several background images were disappearing in IE6. I tried the common solutions first: relative positioning, removing floats, setting widths, etc. and nothing worked. It took me quite a while to uncover the culprit.

href="javascript: void(0);"

 

//I was using it in a common manner:
<a onclick="switchTabs(‘comments’)" href="javascript: void(0);">Comments</a>

Once I removed the href=”javascript: void(0);” from the link everything worked fine. I had searched the Internet for days trying to find the solution to this bug and never found a thing. This is probably because not too many people use href=”javascript: void(0);”… and now I know why.

I’ve been getting into it over the past few weeks, and I’ve found it to be a very powerful and robust library. I remember how impressed I was when jQuery 1.1.3 came out less than a year ago, claiming to be 800% faster than its predecessor. Well, the fellows at jQuery have just released jQuery 1.2.6 and have again made some pretty significant improvements. Beside adding new functionality and fixing bugs they have increased the performance on several key features of the library; for more details check out their Google Spreadsheet.

  • Event Handling is 103% Faster
  • CSS Selectors are 13% faster
  • .offset() is 21% faster
  • .css() is 25% faster

I’m excited to try out the new version for myself. If you haven’t checked out jQuery lately you should give jQuery 1.2.6 a try, it’s amazing.
