How can i call VBscript from Javascript

Question

I have searched the threads here but could not find anything remotely related to what i am trying to do. Basically i want to call vbscript using javascript for the onClick.

Is there a way to call aVBScript for the onClick event from a button that uses Javascript onmouseover and onmouseout events?

I can't seem to get it to work and need help. Below is a snippet of my javascript code and also vb script i would like to call out to:

Javascript code:

<td align="center">
    <input onMouseOver="window.status=me.value" onMouseOut="window.status=''" onMouseOver="window.status=me.value" onMouseOut="window.status=''" type="button" value="Impersonation" class="redBtn" onClick="openPopup('http://internal.mps.cardinal.net/cardcom/index.asp')" />
   </td>
   <td align="center">
    <input onMouseOver="window.status=me.value" onMouseOut="window.status=''" onMouseOver="window.status=me.value" onMouseOut="window.status=''" type="button" value="ServiceNow" class="normalBtn" onClick="openPopup('https://cardinal.service-now.com/navpage.do')" />
   </td>

What i would like to do is call out to the vbscript for the ServiceNow OnClick event.

My VBscript: WScript.Quit Main

Function Main
Set IE = WScript.CreateObject("InternetExplorer.Application", "IE_")
IE.Visible = True
IE.Navigate "https://cardinal.service-now.com/navpage.do"
Wait IE

With IE.Document
On Error Resume Next
  .GetElementsByName("EnterpriseID")(0).value = "admin"
  .GetElementsByName("PASSWORD")(0).value = "admin"
End With

IE.Document.getElementByID("SignInBtn").Click

End Function

Sub Wait(IE)
Do
WScript.Sleep 500
Loop While IE.ReadyState < 4 And IE.Busy 
Do
WScript.Sleep 500
Loop While IE.ReadyState < 4 And IE.Busy 
End Sub

Sub IE_OnQuit

On Error Resume Next WScript.StdErr.WriteLine "IE closed before script finished." WScript.Quit End Sub

Thank you for any help you can provide

ewww.... people still use VBScript in the browser??? Why would you do such a thing? — Spudley, Aug 01 '13 at 13:50
@Drew - please **edit the question** and put the code there, not in a comment. It's unreadable in the comments. — Spudley, Aug 01 '13 at 13:51
@Drew -- if that's an answer, can you please post it as an answer so you can get credit -- and people can read it! — Ernest Friedman-Hill, Aug 01 '13 at 13:51
It's not by choice....but it's the only code i can think of that will auto login to the site. Using vbscript alone works fine but i can't figure out how to call out to it with jscript using the OnClick — Drew, Aug 01 '13 at 13:52
My apologies...i'm new to this site. I'll post the jscript code into the question section — Drew, Aug 01 '13 at 13:53
@Drew - anything you can do in the browser with VBScript can be done just as well with javascript. It looks like the code you've written is basically a simple ajax function; it's pretty well documented how to do that in JS. — Spudley, Aug 01 '13 at 13:54
Why not remove the need to login altogether? If you're holding the admin username/password in cleartext in-page, it sort of defeats the point of having a login form. — Richard A., Aug 01 '13 at 14:01
I've never used JS in that way. I assume there are articles on how that is done on this site? — Drew, Aug 01 '13 at 14:03
It's a requirement to login to the webpage "https://cardinal.service-now.com/navpage.do" — Drew, Aug 01 '13 at 14:04
It's nothing i am able to control or take away as it's housed on an Enterprise — Drew, Aug 01 '13 at 14:05

Yes you can do that, this sample uses onmouseover/out in JS and onClick in VBScript.

  <script type="text/vbscript">
      Function MyVbAlert()
        MsgBox("Hello from VB Script!")
      End Function
  </script>

   <script type="text/javascript">

       function myJsMouseOver(c) {
            c.style.color = 'green'    
       }

       function myJsMouseOut(c) {
           c.style.color = 'black'
       }

   </script>


    <span onclick="MyVbAlert()" onmouseover="myJsMouseOver(this)" onmouseout="myJsMouseOut(this)" >Click Me</span>

This is not calling VBScript from JavaScript, it is calling VBScript from a DOM event listener. – cchamberlain Oct 13 '16 at 16:58

I know this is old but I was looking for a way to call legacy VBScript from newer pages written with javascript. I used something like:

<script language="javascript" type="text/javascript">
function clickProxy() {
    document.getElementById("vbProxy").click(); // initiate click event on the button
}
</script>

<script language="vbscript" type="text/vbscript">
function runVB()
    msgbox "VBScript!"
end function
</script>

And then in the HTML:

<input type="button" id="vbProxy" onclick="vbscript: runVB" value="VB Proxy" style="height:0px;width:0px"/>
<input type="button" onclick="clickProxy()" value="Click Me" style="height:0px;width:0px"/>

DOM elements can see both javascript and vbscript, so I used one button to trigger a "proxy" button, which in turn calls the VBScript. You could even pass params (sort of) by dropping them into hidden input fields.

I didn't test the above, so apologies if there are any mistakes, but you get the idea!
