What have you tried?

[Nine 993]

Try reading all option tags value, put that in an array, use random to get a number, use array [number]

How to do it?

i am new on autoit, please give me little example 

[Nine 993]

Look in help file, for the following statements :

_IETagNameGetCollection ()

Random ()

_ArrayDisplay ()

Each statement is fully described with excellent examples...

It was a basic script

@jmp You've already been given a hint by @Nine. Read the help file, run the examples, write some code to show where you have made an attempt to solve this yourself, then come back and give us an update.

get the count of options, _IEFormElementOptionSelect with mode = byIndex...use Random() to set the integer

[jmp 0]

@Nine, I am tried reading all option tags value using : 

$idlMember = _IEGetObjById($oIE, "dlMember")
$TXT = ""
$items = $idlMember.options
For $item in $items
    $TXT = $TXT & $item.value & @CRLF
Next
MsgBox(0, "", $TXT)

it was getting all option, How can i select randomly one option from these?

Thanks @jdelaney, But It was select sometimes, Most of times it get error in line.

My code is : 

Local $oForm = _IEFormGetObjByName($oIE, "selectdldl")
Local $oSelect = _IEFormElementGetObjByName($oForm, "dlMember")
$iOptionCount = $oSelect.length
$nOption = Random(1, $iOptionCount)
_IEFormElementOptionSelect($oSelect, $nOption, 1, "byIndex")

Possibly because you don't have the flag set on random to return an integer.   it's the third parameter.   Do a consoleoutput of $noption to debug.  otherwise you need to add debugging into the ie function to see what's going wrong

[jdelaney 313]

Oh, byindex is 0 based.   set random to 0, count-1

@jdelaney

I want to skip first option from selection.

[jdelaney 313]

You still must update the second param to $ioptioncount-1

Like this? 

Local $oForm = _IEFormGetObjByName($oIE, "selectdldl") Local $oSelect = _IEFormElementGetObjByName($oForm, "dlMember") $iOptionCount = $oSelect.length $nOption = Random(1, $iOptionCount-1) _IEFormElementOptionSelect($oSelect, $nOption, 1, "byIndex")

[jdelaney 313]

looks good.  Are you actually getting the count of the items from your $oSelect.length?  You might need to get the child nodes count.

ConsoleOutput($iOptionCount & @crlf) to check.
