When running the following locally, the fade in is very smooth, but on a remote server the content loaded into the target div appears, is instantly hidden, and then fades back in again. Why does this happen and how do I fix it? My jQuery (inside the document.ready stuff) looks like this: $(".dataclick").click(function() { $('.clic...

I'm looking for a minimalist template system for javascript, ala John Resig's Javascript Micro Templating. The smaller the better, and if it's jquery based even better. Recommendations? I tried John's micro-templating but ran into a few issues, wanted to see if there are more baked / better packaged solutions out there. [Update] I trie...
I'm running the following code. The button basically adds a chart into the html page. The problem I'm facing is: when I click on the button for the second time, the curve of the former chart fades away (though the labels don't), and I want it to stay. I've tried to debug and this happens when I modify the innerHTML property right at the ...

Hi all, I'd like to start a discussion on the best resources for refactoring tips, with an eye towards Front-End JavaScript refactoring. A friend whose opinion I respect suggests this book, though it uses examples in Java. I understand that the principles of OO refactoring should translate to another language. Let's talk about refactor...
I'm using the jquery ui slider for zooming. It's supposed to zoom from 25% to %500, and about half of the range is used for the first %100 of the size. The slider has values from 1 to 100. I need some function that can be used to calculate zooming based on the slider value, e.g. function getZoom(sliderVal) { //return number from 25...
