Javascript array items via COM dot syntax

Recommended Posts

ozmike

Hi

What is the syntax to access an javascript array item - from auto IT - using the COM dot syntax?

How do you go $js.foo.item(0)

when

$foo = $js.Eval("var foo = [ 1234, 2345 ] ;")

$js = ObjCreate("ScriptControl")
$js.language = "Jscript"

$js.Eval("var foo = [ 1234, 2345 ] ;")
$foo =$js.Eval("foo")
Consolewrite("foo.length =  " & $foo.length & @CRLF)
Consolewrite("foo.item(0) =  " & $foo.item(0) & @CRLF) ; FAILS

See my UDF which  gives you OO arrays in auto IT using Native windows JSOn . 

'?do=embed' frameborder='0' data-embedContent>>

Or the scripting object

 

Yes you can. 2 ways

 

Just extend the array object type - which javascript allows - the advantage of OO?

Add this to your web page

Array.prototype.item =function( i ) { return this }  ;

 

$js = ObjCreate("ScriptControl")
$js.language = "Jscript"
$js.Eval("Object.prototype.item            =function( i ) { return this[i] } ;"); MAGIC
$js.Eval("var foo = [ 1234, 2345 ] ;")
$foo =$js.Eval("foo")
Consolewrite("foo.length =  " & $foo.length & @CRLF)
Consolewrite("foo.item(0) =  " & $foo.item(0) & @CRLF) ; WORKS

 

 


Another solution to
$obj.item(n) 
 
A pure AutoIt solution to get a array object item 
 



func OArrayItem ( $o, $i)
dim $O_index = 0
for $OO in $o

if $i = $O_index then
             return $OO
            endif
$O_index = $O_index + 1
Next
        
EndFunc
$js = ObjCreate("ScriptControl")
$js.language = "Jscript"
$js.Eval("var foo = [ {""ph"" : 1234}, {""ph"" : 2345 } ] ;")
$foo =$js.Eval("foo")
Consolewrite("foo.length = " & $foo.length & @CRLF)

$oitem = OArrayItem($foo, 0)
Consolewrite("$oitem.type " & $oitem.ph & @CRLF)
Consolewrite("$oitem.type " & OArrayItem($foo, 0).ph & @CRLF) ; FAILS

      Hi,
      I'm looking for a way to take a number value from a Row2 of a 2D array and according to this check if files that appear in rows 3-11 in the array exists.
      For example, if the number in Row2 is 5 I need to check for the files in Row 3-6 only, if it is 6 than rows 3-7 and so on.
      I thought on using a FOR loop but I have very little experience with those.
      Can you suggest the best way to do what I need?
      BTW, the files in Rows 3-11 will usually have blank value for any row above the number in Row2 (e.g. Row2 = 5 so Rows3-6 will have values but 8-11 be empty), The values I need are in Column 1 of the array, the name of the key from the INI file that the array was created from is in Column 0.
      Full Example:
      Row2 of Array:
      Col0 = Games# - Col1 = 5
      Rows3-6
      Col0 = Exe2 - Col1 = Path To File
      Col0 = Exe3 - Col1 = Path To File
      Col0 = Exe4 - Col1 = Path To File
      Col0 = Exe5 - Col1 = Path To File
      I need that if Row2 is 5 to check these above for rows if the file exists, if it was 6 then the next row as well and so on up until number 10 in Row2 as it can't go above 10.
      So basically for whatever number in Row2 from 2-10 need to check 1-9 rows from 3-11 to see if the files in Col1 exists and if any of them don't exist it should call a function that shows an error message.
      I'm pretty sure I have the first line of the for look correct:
      For $i = 1 To $aAIO[2][1] Just not sure how to continue from there, also not sure if $i should be equal 1 or 2.
      Help will be appreciated.

      Hello,
      I'm trying to get data from twitter to an array and so far I found an Twitter UDF whish lookes very intresting but couldn't get it to work.
      It lookes not supported any more(2010) and buggy when i read all te replies.
      More around this subject (autoit and twitter) i couldn't find on this forum.
      Is there sombody who know's a good way to get live data from twitter to an array inside autoit?
      (I kinda doubt that this isn't tackled before)
      In the end I was hoping to get all tweets from date to date from an specific subject inside a 2D array to work whit.

      I got a question:  i am trying to run different functions based upon what i select in these radio buttons.(code below)
      it needs to check server 1. then run function 1 or function 2 after what i selected in the checkbox.
      once that function is done it moves to the next one, until it has been trough all 5 
       
      iv'e tried using while loops with different while $i equals to something but then i manualy need to go in and edit the script every time.

      Hi everyone, 
      I'm currently writing a script that allow me to list all currently installed software on a computer but some of the are listed in the HKLM64 hive of the registry whereas 95% of all others are in the HKLM "normal" one.
      Thing is, I'd like to combine these two reg key into one single ListView item.
      Here's my code so far, knowing that it's working on both cases (changing to HKLM64 or HKLM short)
      Thanks in advance for the help
