Secrets of The Javascript - Cross browser strategy

[Mark Reyes]

Hi Bear,

I am very much interested in chapter 11 Developing cross-browser strategies.

How much emphasis were given on this particular chapter? Does this chapter requires knowledge on
several browser quirks (*IE hacks).

Sometimes I encounter problems that works on Firefox but fails heavily on IE. Does this chapter covers the
rules on how to create good javascript functions that will conquer all browsers?

Thanks

No paritcular prior knowledge of IE (or other brower's) quirks are necessary. We tell you about them.

Yup. We cover many approaches form the easy (feature detection) to the more esoteric (feature simulation).

feature detection

..does the words above means that I would learn if this javascript function would work on one browser but would fail on the other...sorry just curious enough..

Feature detection is distinct from browser detection. Rather than determine what course to take based upon the browser, you test to see if the feature exists. A good example of this is most raw Ajax code which tests to see if it should use ActiveX or XMLHttpRequest.
