Re: Pass parameters between Javascript and ASP

Please use the forum's CODE tags when posting.

JavaScript runs on the client. ASP runs on the server. You cannot "pass" variables between them, per se.

The only time ASP runs is when a REQUEST is sent to the web server, either a GET or a POST.

The way you send values to an ASP form is by adding a QueryString to your GET Requests, or by populating form values for your POST Requests (or, "form submits").

Re: Pass parameters between Javascript and ASP

I see. Well, you're passing in a value to the function, correct? Is that value you want to "pass" to the activeX object? I see you're executing the method with "commandParms", but you're never setting "commandParms" equal to anything. Should it contain the value you pass to the JavaScript function?

Okay, I'm going to assume that you want commandParms = "123".

(Toggle Plain Text)

<SCRIPT type="text/javascript" LANGUAGE="JavaScript">
<!--
function startWord(x)
  {
commandParms = document.getElementById(x).value;
   var oShell = new ActiveXObject("Shell.Application");
    var commandtoRun="C:\\Karan\\Automation.exe";
oShell.ShellExecute(commandtoRun, commandParms, "", "open", "1");
  }
  //-->
</script>
</head>
<body>
<form>
<input type="text" name="par_1" value="123">
<input type="button" value="Click me!" onclick="startWord('par_1')">
</form>
</body>
</html>

Re: Pass parameters between Javascript and ASP

The error came out after added the "commandParms = document.getElementById(x).value;"
is the server not read this sentence??

Re: Pass parameters between Javascript and ASP

No, the server wouldn't process that... it's JavaScript, which would run on the client.

Change name="par_1" in the input text element to id="par_1" .

Re: Pass parameters between Javascript and ASP

Thank you for your help.

I use the alert sentence to check the value on getelelment, but the value is "NULL".

do it mean the value can't pass to the function???

Re: Pass parameters between Javascript and ASP

I assure you this works. I have no idea what "getelement" means, sorry.

Here's the most simplified test version I can make for you:

JavaScript / DHTML / AJAX Syntax (Toggle Plain Text)
<html>
<head>
<script type="text/javascript">
function startWord(x)
{
  var commandParms = document.getElementById(x).value;
  alert(commandParms);
}
</script>
</head>
<body>
<form>
<input id="txt" type="text" value="123" />
<input id="btn" type="button" value="Click" onclick="startWord('txt')" />
</form>
</body>
</html>
<html>
<head>
<script type="text/javascript">
function startWord(x)
{
  var commandParms = document.getElementById(x).value;
  alert(commandParms);
}
</script>
</head>
<body>
<form>
<input id="txt" type="text" value="123" />
<input id="btn" type="button" value="Click" onclick="startWord('txt')" />
</form>
</body>
</html>

Re: Pass parameters between Javascript and ASP

That's completely up to you. You have enough now to learn the mechanism and finish it on your own.
