Twitter Bootstrap programmatically open or close an Accordion with javascript
Q: I have a nice accordion in my web app set-up in twitter bootstrap but how can I programmatically open or close a section using javascript?
A: Use the .collapse() function to open, close or toggle a collapsible accordion section.
Consider this 2 section accordion:
[crayon]
The camera settings
The acquisition settings.
[/crayon]
Then, as an example, to automatically open the second accordion section (identified by ‘#category-2’) when the page loads you could do the following:
[crayon]
[/crayon]
This technique can be used to automatically re-open a previously open accordion section on page refresh, to do this first use the history api to update the current page location whenever a user clicks to open an accordion section – store an id to the open section in the page arguments.
Then when the page loads, for example on a refresh, if this argument exists parse it from the page loaction and then call collapse(‘show’) to open the section…
