(AutoIt) Prevent JavaScript Infinite LoopsSee more JavaScript ExamplesDemonstrates how prevent infinite loops or prevent the JavaScript from running for a longer amount of time than allowed.Note: This example requires Chilkat v11.4.0 or greater.
Local $bSuccess = False ; This is the JavaScript we'll run: ; console.log('Starting infinite loop...'); while(true) {}; $oSbScript = ObjCreate("Chilkat.StringBuilder") $oSbScript.Append("console.log('Starting infinite loop...'); while(true) {};") $oJs = ObjCreate("Chilkat.Js") ; Set a limit on the amount of time (in seconds) the script is allowed to run. ; If the JavaScript takes longer than this amount of time, then Chilkat kills the script without crashing the host program. ; The default value of TimeoutSeconds is 0, which indicates no limit. ; For this example, set a limit of 2 seconds. $oJs.TimeoutSeconds = 2 $oResult = ObjCreate("Chilkat.JsonObject") $oResult.EmitCompact = False ; Run the script.. $bSuccess = $oJs.Eval($oSbScript,$oResult) If ($bSuccess = False) Then ; Examine the result for an exception. ConsoleWrite($oResult.Emit() & @CRLF) ; The result contains this: ; { ; "exception": { ; "message": "interrupted - JavaScript exceeded the Chilkat.Js.TimeoutSeconds", ; "stack": [ ; { ; "func": "<eval>", ; "file": "<input>", ; "line": 1, ; "col": 8 ; } ; ] ; } ; } ; Also examine the LastErrorText. ConsoleWrite($oJs.LastErrorText & @CRLF) Exit EndIf ; We should never get here.. ConsoleWrite("Succeeded." & @CRLF) ConsoleWrite($oResult.Emit() & @CRLF)
