I have a vbscript code inside my VF page,

which reads an excel file and displays the content

in a textarea.

Its not working at all. ie if you click the Read button

nothing happens.

Does VF pages support vbscript code?

Here is my code

<apex:page showHeader="false">
 <apex:messages /> 

 <script type="text/vbscript">

  Sub readBtn_OnClick

    Dim fileUrl
    Dim rowIndex
    Dim colIndex
    Dim oldContent
    Dim newContent
    Dim cellContent

    fileUrl = document.form.userFile.value
    Set objExcel = CreateObject("Excel.Application")
    MsgBox "Excel Obj Created"
    Set objWorkbook = objExcel.Workbooks.Open(fileUrl)
    MsgBox "Excel Workbook Created"

    rowIndex = 1
    colIndex = 1
    Do Until objExcel.Cells(rowIndex ,colIndex).Value = ""
        oldContent = document.form.excelContent.value
        newContent = oldContent & objExcel.Cells(rowIndex , colIndex).Value & vbCr & vbLf
        document.form.excelContent.value = newContent 
        rowIndex = rowIndex + 1
    Loop
    objExcel.Workbooks(1).Close
    objExcel.Quit
  End Sub

</script>

<form name="form">
    <input type="file" name="userFile"/>
    <input type="button" value="Read" name="readBtn"/>                         
    <p><textarea rows="10" cols="44" name="excelContent"></textarea></p>
</form>

</apex:page>
