Progressive Enhancement vs. Graceful Degradation The concepts of graceful degradation and progressive enhancement are often applied to describe browser support strategies. Indeed, they are closely related approaches to the engineering of "fault tolerance". These two concepts influence decision-making about browser support. Because they reflect different priorities, they frame the support discussion differently. Graceful degradation prioritizes presentation, and permits less widely-used browsers to receive less (and give less to the user). Progressive enhancement puts content at the center, and allows most browsers to receive more (and show more to the user). While close in meaning, progressive enhancement is a healthier and more forward-looking approach. Progressive enhancement is a core concept of Graded Browser Support. So to my understanding, Unobtrusive Javascript ~ Graceful Degradation not really a good thing and not the same as Progressive Enhancement On 8月16日, 下午10時13分, Pops <[EMAIL PROTECTED]> wrote: > I"ve seen this term referred to a few times, especially here: > > http://simonwillison.net/2007/Aug/15/jquery/ > > What does Unobtrusive Javascript mean? > > I am getting the idea that jQuery offers a way to bypass a user > turning off JavaScript? > > How does jQuery do this? > > Thanks
