I'm using asual jquery address plugin for page navigation. But I have a little problem. When I'm inserting mypage.html#first_paragraph address plugin recognize this as new page, not as "goto operation". And I just want this link to go to that place of my page. How can I do this? For example: http://developer.android.com/reference/android/widget/ListView.html#addFooterView(android.view.View ) see, when you click on this link its automatically goes to that place of page (with the addFooterView method) When I'm trying to release this using jquery address plugin, this (<a href="ListView.html#addFooterView(android.view.View)">ListView</a>) link (it opens new page) is recognizing as link (not "go to this part of page" operation)

Is there a way of catching the modification of a specific data attribute (i.e. 'data-whatever')? My first thought was to go with DOM mutation observer but was wondering if there's any 'easier' way through jQuery?
