Javascript数组到VBScript

Question

我有一个使用Javascript构建的对象数组,我需要使用VBScript读取它(如下例所示).我找不到一种方法来循环我的VbScript代码中的数组作为myArray对象.

这个例子简化了我的问题.我无法更改页面的默认语言.该myArray对象必须使用JavaScript来构建.必须使用内联vbscript输出数组.

<%@ 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

派对有点晚,但您可以为标准的javascript数组添加自定义方法.此方法也将在VBscript中提供.所以将此代码添加到您的脚本中:

// add an Item() method to the standard array object so we can iterate arrays in VBscript.
Array.prototype.Item = function(idx) {
    return this[idx];
};

你可以使用:

myArray.Item(0)

在VBscript中获取数组中的一个项目.

似乎JScript数组方法仍然可以通过VBScript使用：

<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
%>
