javascript - returning to root page with crossroads.js and hasher.js -


i'm starting out crossroads.js , hasher.js , having success parsing of routes. don't understand how root of page. know i'm not saying right, here's issue:

  1. i navigate http://example.com , see need see.

  2. i change hash http://example.com/#/foo , need change dom.

  3. i try click in browser, , i'm suck here.

maybe need define "root" route in crossroads? doing wrong history?

as understand on halfway in both settings (hasher + crossroads).

adding route "root" pattern crossroads triggers defined handler route if root pattern matches. , handler invokes display root page content.

and second issue hasher must configured. see difference between hasher.sethash() , hasher.replacehash() on hasher doc. use sethash if want keep history , use browser feature.

the whole process be:

  1. change url hasher.sethash(new_hash_value), manually enter url navigation bar or use button in browser
  2. hasher recognize hash has been changed , triggers crossroads further processing new url
  3. crossroads parse new hash , invokes display root page (this requires route root hash pattern)

prepare hasher able listen changes: 

function parsehash(newhash, oldhash){   crossroads.parse(newhash); }  hasher.initialized.add(initialparse); //parse initial hash hasher.changed.add(parsehash); //parse hash changes hasher.init(); //start listening hash changes

and of course define route root page able invoke display root content:

crossroads.addroute("", function() {      // call displaying root page   });

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
