javascript - Jquery循环并在textarea中显示json数据

Question

我通过 getJSON 获取此数据，它在名为 results 的变量下返回此数据。

这是数据:

{
    "ok": true,
    "messages": [
        {
            "text": "Message 1",
            "username": "bot",
            "type": "message",
            "subtype": "bot_message",
            "ts": "1454394770.000002"
        },
        {
            "text": "Message 2",
            "username": "bot",
            "type": "message",
            "subtype": "bot_message",
            "ts": "1447656207.000002"
        },
        {
            "user": "5434543",
            "type": "message",
            "subtype": "ch_join",
            "text": "<@U0456TA8|tre> has joined",
            "ts":654565.444"
        }
    ],
    "has_more": false
}

我知道如何将其中之一添加到我的文本区域:

$("#myTextarea").val(results.messages[0].text);

我的问题是...如何将其全部添加到我的文本区域中？

Answer 1

var output = "";
jQuery.each(results.messages , function (index, element){
  output += element.text + "something to put between the text perhaps?";
});
$("#myTextarea").val(output);
