Execute javascript in a javascript-disabled webview android -

i'm working android webview, have disabled server js following code:

webview.getsettings().setjavascriptenabled(false); 

but wanna execute javascript (to change background color, text color, etc) there way without re-enable js?

thank much!

in order make javascript work, workaround, re-enable website's javascript, run javascript, , disable again. allow interact dom short period of time, without letting user make use of of website's javascript.
