Rynhasautism Posted August 4, 2020 Share Posted August 4, 2020 Is there a way to make while loops check the expression after each statement is executed? If not what are some ways to emulate this? Should I just put all the statements into an array then use for in next loop to kind of do the same thing? Link to comment Share on other sites More sharing options...
Moderators JLogan3o13 Posted August 4, 2020 Moderators Share Posted August 4, 2020 @Rynhasautism how about an example of what you're meaning? It sounds like your While expression will change once you have entered the loop, and there are a couple of ways to skin the proverbial cat. But rather than guessing at what you're trying to do, and then crafting an example that would make sense to you, a detailed explanation of what you want the loop to do step by step would be helpful.

Rynhasautism Posted August 4, 2020 Author Share Posted August 4, 2020 well a normal while is like While Expression() = $valueIWant Statement1() Statement2() Statement3() WEnd Where it only checks the expression at the start of the loop. I'm looking to do something like Expression() = $valueIWant Statement1() Expression() = $valueIWant Statement2() Expression() = $valueIWant Statement3() Was thinking of something like this at first but it doesn't exit the loop While $flag = $flagIWant Statement1() WEnd Func Statement1() Return $flag = Expression() EndFunc The for loop thing I was talking about was something like $aArray [1][2] = ["function", $parameter] For $i = 1 To UBound($aArray) - 1 If Expression() = $valueIWant Then Local $FuncName = FuncName($aArray[$i][0]) call($FuncName, $aArray[$i][1]) EndIf Next Link to comment Share on other sites More sharing options...
Danp2 Posted August 5, 2020 Share Posted August 5, 2020 Couldn't you turn the logic around and do something like this? -- While 1 If Expression() <> $valueIWant Then ExitLoop Statement1() If Expression() <> $valueIWant Then ExitLoop Statement2() If Expression() <> $valueIWant Then ExitLoop Statement3() WEnd WebDriver UDF [GH&S] Latest version Wiki FAQs Link to comment Share on other sites More sharing options...
Rynhasautism Posted August 5, 2020 Author Share Posted August 5, 2020 Yeah lightweight trying to be somewhat efficient and do it in the least amount of instructions possible while avoiding the ctrl+v, ctrl+v, Link to comment Share on other sites More sharing options...
Sidley Posted August 5, 2020 Share Posted August 5, 2020 A switch statement maybe? While 1 local $ReturnValue = Expression() Switch $ReturnValue Case 1 Statement1() Case 2 Statement2() Case 3 Statement3(); Case Else Exit EndSwitch WEnd Link to comment Share on other sites More sharing options...
