    [SOLVED]how do you check if option elements exist

    I'm creating a HTML application.

    How can you check with VBscript if option element exists in the html code?

    I have to check if there are options inside the select element like in this example:

    Code:
    <select name="LangChooser">
       <option value="sp">Spanish</option>
       <option value="en">English</option>
    </select>
    ...OR if there are not option elements like in this example:

    Code:
    <select name="LangChooser">
    </select>
    Thanks!

    Try something based on this:
    Code:
    <script language="VBScript">
    Option Explicit
    
    Sub CheckLang ()
    
      Dim selectElement
    	
      Set selectElement = document.getElementById("LangChooser")
    
      If selectElement.options.length = 0 Then
        alert "No options"
      Else
        alert "Number of options = " & selectElement.options.length
      End If
      
    End Sub
    
    </script>

    </script>
