Straight to the point. One very common problem with ajax->dynamically updated pages is that, since content is fetched and updated within the page itself, the original webpage url doesn't change and hence it is impossible to bookmark/remember them.
For example, the video comments on youtube. If a video has ten pages of comments, when clicking the page numbers, the comments are updated dynamically without the url ever changing. So what if you want to bookmark page no:9 ? Not possible.
The simplest solution is to make use of the 'url fragment identifier' or whatever that comes after the # in a url. eg: http://something.com/page#here-it-goes
Javascript can update the fragment identifier dynamically with a simple
CODE:
document.location.href = '#whatever';
document.location.href = '#whatever';
On page load, something like RegEx could be used to parse the query
CODE:
var thisUrl = document.location.href;
var query = thisUrl.split('#');
alert(query[1]);
var thisUrl = document.location.href;
var query = thisUrl.split('#');
alert(query[1]);
So if page numbers or required variables are set as the fragment identifiers, it is possible to efficiently make Javascript process it (nearly) and make Ajax act normal with page urls.
