javascript - 遍历 JSON 数组，显示两个然后计数

Question

好吧，我是一个 JSON 菜鸟，只有基本的 jQuery 知识，而且我到处寻找解决方案，但找不到。非常感谢任何帮助。

我需要:

1) 遍历 JSON 数组(有效)

2) 显示“mbrname”的前两个结果

3) 然后显示其余结果的计数。

我正在成功循环并显示所有 mbrname 结果。但不知何故我只需要显示前两个，如果有更多显示“+ # others”

这是最终产品的屏幕截图:

这是我的代码现在产生的结果:

这是我的 JSON:

{
 "messages":{
  "message":[
     {
        "date-time":"June 2, 2013 12:22 pm",
        "subject":"This is the message subject",
        "msg-string":"001",
        "newmsg":"true",
        "attach":"shop-cart",
        "recipient":[
           {
              "mbrname":"D. Craig",
              "mbr-href":"#craig"
           },
           {
              "mbrname":"N. McCoy",
              "mbr-href":"#mccoy"
           },
           {
              "mbrname":"J. Smith",
              "mbr-href":"#smith"
           },
           {
              "mbrname":"B. Wardlaw",
              "mbr-href":"#wardlaw"
           }
        ]
     },
     {
        "date-time":"May 23, 2013 12:22 pm",
        "subject":"This is a great subject",
        "attach":"none",
        "msg-string":"002",
        "newmsg":"true",
        "recipient":[
           {
              "mbrname":"D. Craig",
              "mbr-href":"#craig"
           },
           {
              "mbrname":"N. McCoy",
              "mbr-href":"#mccoy"
           }
        ]
     },
     {
        "date-time":"May 11, 2013 12:22 pm",
        "subject":"Interested in your tomatoes",
        "attach":"shop-cart",
        "msg-string":"003",
        "newmsg":"false",
        "recipient":[
           {
              "mbrname":"J. Smith",
              "mbr-href":"#smith"
           }
        ]
     }
  ]
 }
}

这是我的“mbrname”部分的 jquery，它成功地提取了名称并将它们附加到我的 HTML 中:

$.each (message.recipient, function (message, recipient) {
var mbrPart = recipient.mbrname + ', ';
var currentUser = $('#' + newID + ' .name');

$(currentUser).append(mbrPart);

});

在此先感谢您的帮助!

我会保持简单，不需要做任何循环:

var recipientString = message.recipient[0].mbrname;
var count = message.recipient.length;

if (count > 1)
    recipientString += ', ' + message.recipient[1].mbrname;

if (count > 2)
    recipientString += ' + ' + (count - 2) + ' others';

$('#' + newID + ' .name').append(recipientString);
