Translating a Javascript array into VBScript

I have encountered a challenge with my coding project - I have an array of objects created using Javascript, and now I need to access and manipulate it using VBScript. Unfortunately, I am struggling to figure out how to properly loop through the array in my VBScript code using the myArray object.

This example provided is a simplified version of my issue at hand. I am unable to switch the default language of the page. The creation of the myArray object must remain in javascript. Additionally, I have to display the array utilizing inline vbscript.

<%@ Language="VBScript" %>

<script language="javascript" runat="server">

    var myArray = [
        {
            name: "object 1"
        },
        {
            name: "object 2"
        },
        {
            name: "object 3"
        }
    ];

</script>

<%
    Response.Write(myArray) ' [object Object],[object Object],[object Object]
    'Response.Write(myArray(0)) ' ERROR
    'Response.Write(myArray[0]) ' ERROR
    Response.Write(myArray.[0]) ' [object Object]
    Response.Write(myArray.[0].name) ' object 1
    Response.Write(VarType(myArray)) ' 8
    Response.Write(myArray.length) ' 3
    Response.Write(VarType(myArray.[0])) ' 8
    Response.Write(VarType(myArray.[0].name)) ' 8
    Response.Write(TypeName(myArray)) ' JScriptTypeInfo
    Response.Write(TypeName(myArray.[0])) ' JScriptTypeInfo

    ' ERROR
    ' Type mismatch: 'UBound'
    'Response.Write(UBound(myArray))

    ' ERROR
    ' Object doesn't support this property or method: 'myArray.i'
    'Dim i
    'For i = 0 To myArray.length - 1
    '    Response.Write(myArray.[i])
    'Next
%>

Answer №1

While it may be belated, you have the ability to enhance the standard javascript Array by incorporating a custom method. By doing so, this method will then also be accessible in VBscript. Incorporate the following code into your script:

// Incorporate an Item() method into the regular array object in order to navigate through arrays in VBscript.
Array.prototype.Item = function(idx) {
    return this[idx];
};

You can then utilize:

myArray.Item(0)

to access one of the items within the array in VBscript.

Hope this helps!

It appears that the JScript array methods can still be accessed using VBScript:

<script language="javascript" runat="server">
    var myArray = [
        {
            name: "object 1"
        },
        {
            name: "object 2"
        },
        {
            name: "object 3"
        }
    ];
</script>

<%
    Do While myArray.length > 0
        response.write myArray.shift().name
        response.write "<br>"
    Loop
%>

        response.write "<br>"

Avoid using arrays and instead opt for a dictionary object like the example below.

<%@ Language="VBScript" %>

<script language="javascript" runat="server">

    var myArray = [
        {
            name: "object 1"
        },
        {
            name: "object 2"
        },
        {
            name: "object 3"
        }
    ];

    var myDictionary = Server.CreateObject("Scripting.Dictionary");

    for (var myArrayIndex = 0; myArrayIndex < myArray.length; myArrayIndex++) {
        myDictionary.Add(myArrayIndex, myArray[myArrayIndex]);
    }

</script>

<%
    Dim index
    For index = 0 To UBound(myDictionary.Keys)
        Response.Write(myDictionary.Item(index).name)
    Next
%>

If you want to simplify the printing process, you can utilize a JScript function for delegation:

<%@ Language="VBScript" %>
<script language="javascript" runat="server">
    var myArray = [
        {
            name: "object 1"
        },
        {
            name: "object 2"
        },
        {
            name: "object 3"
        }
    ];
</script>

<%
    '// vbscript
    Response.Write(TypeName(myArray)) ' JScriptTypeInfo

    Response.Write printArr(myArray)

    '// more vbscript
%>

<script language="javascript" runat="server">
    function printArr(arr) 
    {
        for (var i = 0; i < myArray.length; i++)
        {
            Response.Write("<br />index " + i + " = " + myArray[i].name);
        }
    }
</script>

        }
