Access array in array in javascript
提问by Pankaj
I am getting a JSON reply, like following:
我收到 JSON 回复，如下所示：
[{
"order_id": "12",
"customer": "user user",
"status": "Pending",
"date_added": "02\/09\/2012",
"total": "0.00",
"action": [{
"text": "View",
"href": "http:\/\/localhost\/oc\/admin\/index.php?route=sale\/order\/info&token=92a80574e5fcbf3e2d021404cfaae1a4&order_id=12"
}]
}]
have a look on action key, it's value is again an array. I am trying to get action key values by following code but it is showing undefined to me
看看操作键，它的值又是一个数组。我正在尝试通过以下代码获取操作键值，但它向我显示未定义
function (data) {
if (data) {
for (var i = 0; i < data.length; i++) {
$('div.dashboard-content table.list tbody tr:first').before(
'<tr id="' +
data[i]['order_id'] +
'"><td class="right">' +
data[i]['order_id'] +
'</td><td class="left">' +
data[i]['customer'] +
'</td><td class="left">' +
data[i]['status'] +
'</td><td class="left">' +
data[i]['date_added'] +
'</td><td class="right">' +
data[i]['total'] +
'</td><td class="right"> [<a href="' +
data[i]['action']['href'] + '">' +
data[i]['action']['text'] +
'</a>]</td></tr>'
);
}
}
}

Like you said, actionis an array. Thus, you can't access it using data[i]['action']['href']. You have to use a subscript to indicate the position of the array that you want. For example, to access the first position, you'd use:
就像你说的，action是一个数组。因此，您无法使用data[i]['action']['href']. 您必须使用下标来指示所需数组的位置。例如，要访问第一个位置，您可以使用：
var href = data[i].action[0].href;
var text = data[i].action[0].text;

actionis an array containing an object with a property called text. Change:
action是一个数组，其中包含一个具有名为 text 的属性的对象。改变：
data[i]['action']['text']
to:
到：
data[i]['action'][0]['text']
