javascript - what happens when i refresh a jquery mobile page -

-

what happens when jquery mobile page refreshed?
use ajax fetch data in variable called "json" on page1, when user clicks particular dynamically generated element, store id of clicked element in session variable , changepage() new jqm page2 use json.thepropertyiwant generate list, works fine, , forward buttons work if refresh page2 json.thepropertyiwant becomes undefined here error get:

uncaught typeerror: cannot read property 'responsedata' of undefined

i using multipage in single html5 page model

edit:

  • i have used variable name json , not json typed emphasize, think foolish!
  • i have figured problem. mistake was assuming page refresh call pageinit page on works no differently normal html page refresh , triggers document.ready each time , pageinit page on.
    is there way listen pagerefresh event , override normal functionality?

i believe generate dynamic content of page2 in event. believe event pageinit or pagecreate. events fire once (if have ajax page load set true). happens request data when load page1 (something pageinit?) when refresh page2, data not there because event request data in, not firing, normal, because when refresh page2, page1 has nothing it. post section of code request data, , section generate dynamic content page2 more.

Does Firefox offer AppleScript support to get URL of windows? -

-
i trying write applescript that, among other things, gets url of every open webpage in firefox. in safari (and chrome), done simply: tell application "safari" return url of every tab in every window however, seems me firefox offers no real applescript support, such getting url of tab or window. when google terms "firefox" , "applescript" together, firefox bug requests asking applescript support restored, last updated in 2010 or 2011 (like this , this ). am right in thinking, then, firefox no longer offers proper applescript support? realize there semi-workarounds, such simulating key-commands in applescript, aren't practical purposes. to see of applescript commands firefox responds to, launch applescript editor, select menu file > open dictionary... , , choose firefox application. you'll find you're expecting: firefox doesn't offer useful applescript commands.
