Question

我有一些javascript数组，我无法控制格式或变量名称。我需要将它们中的6个组合成一个json数组。我有它非常接近，但似乎无法让它迭代变量列表以及数组元素的数量。

对我来说很明显，我不记得如何处理JS中的变量或迭代，以及我以前可以使用的一些帮助。

我需要解析其输出的软件会产生类似于以下内容的内容：

    <script type="text/javascript">
    var orderNum = 'OrderNum-485';
    var orderSubTotal ='130.8';
    var orderTotal  ='130.8';
    var numOfItems ='4';
    var items =new Array('Item Name 1','Item Name 2','Item Name 3','Item Name 4');
    var ids =new Array('item-id-1','item-id-2','item-id-3','item-id-4');
    var codes =new Array('ITEM-CODE-1','ITEM-CODE-2','ITEM-CODE-3','ITEM-CODE-4');
    var qtys =new Array('1','1','1','1');
    var price =new Array('12.95','46.7','1.2','69.95');
    var orderTax ='0';
    var orderShipping ='0';
    var appliedPromoIdList ='';
    var coupon ='';
    var storeId ='store_id';
    var activeShipPromotionCount ='';
    var itemImages =new Array('http://image_url','http://image_url','http://image_url','http://image_url');
</script>

由于我需要传递数据的软件也需要以下内容（作为对象，我设法使用字符串完成它）：

[
         {
            "item_id":"item-id-1",
            "desc":"ITEM-CODE-1",
            "amount":"12.95",
            "quantity":"1",
            "name":"Item Name 1",
            "image": "http://image_url",
         {
            "item_id":"item-id-2",
            "desc":"ITEM-CODE-2",
            "amount":"46.7",
            "quantity":"1",
            "name":"Item Name 2",
            "image": "http://image_url",
     ]

这就是我想出的：

<script type="text/javascript">
    var orderId = orderNum;
    var createItemObjects = function() {
    var keys = new Array ("item_id","desc","amount","quantity","name","image");
    var yahooKeys = new Array ("ids","codes","price","qtys","items","itemImages");
    var item,cartItems = [];
    var c = numOfItems;
    var k = yahooKeys.length;
    var i = 0;
    item = {};
    for (; i < k; i++) {
        var arrayName = yahooKeys[i].toString();
        var buffer = eval('' + arrayName);
        item[keys[i]] = buffer[0] //Ideally this should be the full range of 0-3 so that you can see each of the 4 items.
        document.write("<br />Loop: "+i);
        cartItems.push(item);
    }
    return cartItems;

它生成格式正确的数据，但缓冲区硬编码值指示的元素的6个相同副本

有些事情：

function createItemObjects(items, ids, codes, qtys, prices, images) {
    var check = items.length === ids.length && ids.length === codes.length &&
            qtys.length === codes.length && prices.length === images.length;
    if(!check) throw 'Arrays do not match';
    var results = [];
    for(var i = 0; i < items.length; ++i) {
        results.push({
            item_id: ids[i],
            desc: codes[i],
            amount: parseFloat(prices[i]),
            name: items[i],
            quantity: qtys[i],
            image: images[i]
        })
    }
    return results;
}

var data = generate(items, ids, codes, qtys, prices, itemImages);
var json_string = JSON.stringify(data);

使用Javascript将多个javascript数组合并到JSON中
