Question

我通过getJSON获取此数据，该数据将此数据返回到名为results的变量。

以下是数据：

{
    "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
}

我知道如何将其中一个添加到我的textarea：

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

我的问题是......如何将所有内容添加到我的textarea？

Answer 1

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

Answer 2

你可以循环：

    var _val = $("#myTextarea").val(); // Fetching the new value and adding it to previous value
    [].forEach.call(results.messages, function (inst) {
        _val += inst.text;
    });

    $("#myTextarea").val(_val); //setting it as a new value of textarea.

Jquery循环并在textarea中显示json数据
