How can i style mobile-jquery's back button?

normally we could specify data-theme = "a" or b or c, etc at any div. however as "Back" button is auto generated by jQuery mobile, how to specify its theme?

Thanks, -开发者_高级运维wan

The button style can be changed using the following:

$.mobile.page.prototype.options.backBtnTheme = "b";

---

just found out that we could simply put data-theme at header div however it did not fully work -- (change back to blue always) if you click back button once -- and go back to the same page..

it is an existing bug and the workaround is by removeClass below --- and bind it at pagebeforehide.

jQuery("#page_id_e.g.123').removeClass("ui-btn-active");
