powershell - Get hashtable value by key of group object under strict mode version 2? -


the following script, pivot array list x , y, doesn't work. ($hashvariable.x not working). how rewrite it? seems it's not easy simple value key in hashtable under strict mode.

set-strictmode -version 2 # change 2 1 work  $a = @('a','b','x',10),       @('a','b','y',20),       @('c','e','x',50),       @('c','e','y',30)  $a | %{      new-object psobject -prop @{"label" = "'$($_[0])','$($_[1])'"; value=@{ $_[2]=$_[3]}}  } |  group label | % {     "$($_.name), $($_.group.value.x), $($_.group.value.y)" # error     #"$($_.name), $($_.group.value['x']), $($_.group.value['y'])" # empty x,y }

expected result.

 'a','b', 10, 20 'c','e', 50, 30

error:

 property 'x' cannot found on object. make sure exists. @ line:6 char:35 +     "[$(@($_.name -split ",") + @($_.group.value.x, $_.group.value.y))]" +                                   ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~     + categoryinfo          : notspecified: (:) [], propertynotfoundexception     + fullyqualifiederrorid : propertynotfoundstrict

not sure want, best guess. should accumulate objects in 1 group in single hashtable object instead of creating separate hashtable each input object:

$a = ('a','b','x',10),       ('a','b','y',20),       ('c','e','x',50),       ('c','e','y',30)  $a | group-object {$_[0]},{$_[1]} | select-object values,               @{                   name='group'                   expression={                       $_.group |                       foreach-object {$t=@{}}{$t.add($_[2],$_[3])}{$t}                   }               } | foreach-object {     '''{0}'',''{1}'', {2}, {3}'-f@($_.values;$_.group['x','y']) }

i'm trying link specific pdf page msoutlook'10 or msword'10, #page=... anchor particularly useful , works fine elsewhere. unfortunately when click [ctr-k] in outlook or winword, links re-formatted assuming unc path. pdf file located on shared drive. using "file:" prefix links open pdf in adobe reader (outside of browser), , "http:" open inside browser. issue seem need open in browser "file:" prefix in order anchor work. know anchors work inside browser. outlook uses windows/explorer default program (based on file extension) seems open in adobe reader neglecting anchor. is aware of solution, link specific page or bookmark of shared-pdf ms outlook and/or winword link? common references: mailermailer.com/...anchor-tags-html-emails campaignmonitor.com/...anchor-links-in-email-newsletters/ stackoverflow.com/...anchor-in-pdf-document

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
