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>

I have a requirement where through VF page, user will upload an Excel file.

Controller has to read this excel file and display the values in the same page.

Now my question would be

1. Is it possible to read the excel content in controller class?

2. If it is possible, can you explain me with some sample code?
