问题 How can I hide an Excel tab programmatically through Javascript. ExcelSheetName.Visible=False doesn't seem to work. I've googled a lot but yet not received the right solution. How to do that ? 回答1: To hide an Excel sheet, set the Visible property of the corresponding Worksheet object to 0 or false . For example, if you have an Excel file with two sheets named Sheet1 and Sheet2 , the following code will open this file with the Sheet1 hidden: var objExcel = new ActiveXObject("Excel.Application"

问题 In a normal browser javascript environment, you always have the global window object to fall back on but is there a default accessible global object for the Microsoft JScript Runtime or at least a way to check for one? 回答1: According to MSDN, there is a Global object, however a quick test reveals that it is not directly accessible: WScript.Echo(Global.escape('hello world')); // Error: 'Global' is undefined What you can do, however, is take advantage of the fact that this in a global context

问题 I have a javascript function that returns a constructor (see code sample below). How would I document this with the @returns tag of jsdoc. It doesnt seem correct to do @returns {MyConstructor} because that implies I am returning an instance of "MyConstructor" rather than the constructor itself, right? function MyConstructor() { var self = this; self.myFunction = function() { return true; }; self.getMyFunctionResult = function() { return self.myFunction(); }; } /** * @returns {?} A constructor

问题 There are many reasons to want to split file into chunks - mainly for network transfer (e.g. e-mail attachments) but I'm sure there are scenarios that could require such thing I cannot imagine. So how can a file be split into chunks that can be easily assembled back to original file (including non-windows systems) ? What are possibilities: MAKECAB - the built-in Windows archiver - it can compress file and split it , but will be difficult to assemble the file on non-Windows machine. WSH

问题 I have a JScript script that runs using cscript.exe . It creates a shortcut on the desktop (and in the start menu) that runs cscript.exe with parameters to run another JScript script. It looks, in relevant part, like this: function create_shortcut_at(folder, target_script_folder) { var shell = new ActiveXObject("WScript.Shell"); var shortcut = shell.CreateShortcut(folder + "\\Run The Script.lnk"); shortcut.TargetPath = "cscript"; shortcut.Arguments = "\""+target_script_folder+"\\script.js\"

问题 I'm trying to create a text file using the Scripting.FileSystemObject in JScript. I can't seem to figure out how to create the file if a directory in the file doesn't already exist. For example: var fso = new ActiveXObject("Scripting.FileSystemObject"); // Getting a JScript runtime error of "Path not found" fso.CreateTextFile("\\\\pathA\\pathB\\DirectoryDoesntExistButIWantItTo\\newfile.txt", true); I've been looking all over but it seems like the documentation on this isn't neatly put in one

问题 I'm using following code in JScript (WSH) to connect to local registry using WMI: var registry = GetObject('winmgmts:{impersonationLevel=impersonate}!\\\\.\\root\\default:StdRegProv'); and that works. Then I have to determine if I'm allowed to delete key without really trying to delete it (e.g. perform a non-destructive check). I looked over docs and found that I need StdRegProv.CheckAccess() method. Problem is that CheckAccess returns result as out argument and I could not find VBScript's

问题 Having trouble getting this code to work. I can run the script (with changes) in vbscript and it runs fine. But I cant get this version to return a ping error return value other than 0. Any help is appreciated. This is scanning a list of remote machines with checkboxes and returning the checked values. I want to run the ping to verify the remote machine are there before continuing. But with a error return of 0 for all queries its useless. function statuschk3(){ var checkedValue = null; var

问题 I'm running my JScript file using cscript.exe. In the script I need to call an external console command and get the output. Tried: var oShell = WScript.CreateObject("WScript.Shell"); var oExec = oShell.Exec('cmd /c dir'); WScript.Echo("Status "+oExec.Status); WScript.Echo("ProcessID "+oExec.ProcessID); WScript.Echo("ExitCode "+oExec.ExitCode); and var oShell = WScript.CreateObject("WScript.Shell"); var ret = oShell.Run('cmd /c dir', 1 /* SW_SHOWNORMAL */, true /* bWaitOnReturn */); WScript

问题 I have the following JScript code: var conn = new ActiveXObject ("ADODB.Connection"); conn.Open("Driver={MySQL ODBC 5.1 Driver};Server=localhost;Database=blah_blah_blah;User=foo;Password=bar;"); var cmd = new ActiveXObject("ADODB.Command"); cmd.ActiveConnection = conn; var strSQL = "SELECT id FROM tbl_info WHERE title LIKE :search ORDER BY id"; var search = "test"; try{ cmd.CommandText = strSQL; var param = cmd.CreateParameter(':search', 200, 1, 100, search); cmd.Parameters.Append(param); var
