javascript - Setting window.pageYOffset in Firefox doing nothing? -


i'm using recent version of firefox.

i'm trying window scroll position before submitting form.

in html head of page there's code: if (sessionstorage.top !== null) { window.pageyoffset = sessionstorage.top; }

and later validation function called has following line in it: sessionstorage.top = window.pageyoffset; since function submits form page automatically reloaded.

i've verified validation function called, executing way through including line above.

i've verified code in html head being executed (including inside if statement - sessionstorage.top not null.

i've verified both sessionstorage.top , window.pageyoffset set 630.

yet window stays @ position 0 (zero).

i've tried setting window.pageyoffset directly 630 , nothing. page stays @ topmost (default) position.

what missing?

because readonly? use window.scrolltop = offsetvalue; set scroll position.
