什么 是jquery BBQ?
这是一个jquery插件，BBQ的意思是back button & query。你知道的，以前的jqueryTAB在点击后都无法通过后退和前进恢复原来的点击事件等。而BBQ在每次点击的时候都相当于在历史里加入了一个记录。也就因此可以使得我们能够通过浏览器的前进、后退来重现刚才的点击。

jQuery BBQ leverages the HTML5 hashchange event to allow simple, yet powerful bookmarkable #hash history. In addition, jQuery BBQ provides a full .deparam() method, along with both hash state management, and fragment / query string parse and merge utility methods.
This plugin and the jQuery urlInternal plugin supersede the URL Utils plugin.

Note: If you’re using jQuery 1.3.2 or earlier and need BBQ to merge query string or fragment params containing [], you’ll want to include the jQuery 1.4 .param method in your code.
Also, my article Cooking BBQ: the original recipe gives a history of jQuery BBQ along with some plugin authoring guidelines, if you’re interested.
What jQuery BBQ allows you to do:
While this brief overview will give you the broad strokes, for specifics you should look at the the basic examples below, read the documentation, and check out the full examples listed above.
- Deserialize any params string, the document query string or fragment into an object, including the new jQuery.param format (new in jQuery 1.4, read more here). (example)
- Merge any URL plus query string or fragment params—in an object, params string or second URL (including the current document location)—into a new URL.
- Update the “URL attribute” (ie.
a[href],img[src],form[action], etc) in multiple elements, merging any URL plus query string or fragment params—in an object, params string or second URL (including the current document location)—into a new URL, which is then set into that attribute. - Push (and retrieve) bookmarkable, history-enabling “state” objects or strings onto the document fragment, allowing cross-browser back- and next-button functionality for dynamic web applications (example 1, example 2, example 3)
- Bind event handlers to a normalized, cross-browser hashchange event (example 1, example 2, example 3)
These working examples, complete with fully commented code, illustrate a few ways in which this plugin can be used.
