推荐答案

很麻烦，但 stripting.dictionary :: items 作为安全数组返回，因此在某些情况下(ADSI查询)，以下工作有效，但是YMMV在尝试使用二进制数据方面表现出了很大的优势.

Hacky but stripting.dictionary::items is returned as a safe array so in some circumstances (ADSI queries) the following works, however YMMV significantly in trying this with binary data.

function getSafeArray(jsArr) {
    var dict = new ActiveXObject("Scripting.Dictionary");
    for (var i = 0; i < jsArr.length; i++)
    dict.add(i, jsArr[i]);
    return dict.Items();
}

//to a safe array
var safearr = getSafeArray([11,22,33]);

//back to a js array
var jsArr = new VBArray(safearr).toArray();

log(jsArr[2])
