我需要访问嵌套数据并将其动态添加到下拉菜单中。使用场景是jquery mobile web app。因此，ajax 调用将 curls 转换为 php，然后将 json 返回到分解数据的 Web 应用程序。
这是一个对象的示例（注意：它已在 php 中解码，然后将被重新编码）
[rates] => Array
(
[0] => stdClass Object
(
[type] => rate
[categoryID] =>
[duration] => PT60M
[cost] => 5.00
[recordID] => PT60M|59
[summary] => $5 for the first 60 minutes, then $5 for each additional 60 minutes
[summaryColumns] => Array
(
[0] => stdClass Object
(
[type] => rateSummaryColumn
[text] => $5.00
[align] => right
[lines] => 1
)
[1] => stdClass Object
(
[type] => rateSummaryColumn
[text] => 60 minutes
[align] => right
[lines] => 1
)
)
)
[1] => stdClass Object
(
[type] => rate
[categoryID] =>
[duration] => PT120M
[cost] => 10.00
[recordID] => PT120M|59
[summary] => $10 for the first 2 hours, then $5 for each additional 60 minutes
[summaryColumns] => Array
(
[0] => stdClass Object
(
[type] => rateSummaryColumn
[text] => $10.00
[align] => right
[lines] => 1
)
[1] => stdClass Object
(
[type] => rateSummaryColumn
[text] => 2 hours
[align] => right
[lines] => 1
)
)
)
[2] => stdClass Object
(
[type] => rate
[categoryID] =>
[duration] => PT180M
[cost] => 15.00
[recordID] => PT180M|59
[summary] => $15 for the first 3 hours, then $5 for each additional 60 minutes
[summaryColumns] => Array
(
[0] => stdClass Object
(
[type] => rateSummaryColumn
[text] => $15.00
[align] => right
[lines] => 1
)
[1] => stdClass Object
(
[type] => rateSummaryColumn
[text] => 3 hours
[align] => right
[lines] => 1
)
)
)
我需要访问摘要列中的文本并将它们附加到下拉列表中，其中包含 rate[0].summaryColumns[0].text + rates[0]summaryColumns[1].text 的 [text]。我有一个 each 语句，将每个文本作为一个选项附加，但我需要将其中两个组合在一起 - 所以需要重写
var _rate = result.rates;
$.each(_rate, function(i, vDetails) {
var vRate = (vDetails.summaryColumns);
$.each(vRate, function(i2, vHandle){
//console.log(vHandle.text);
$('#rates').append($('<option/>').attr("value", vHandle.text).text(vHandle.text));
});
});
如果可以，请提出建议-谢谢。
