循环通过JSON数组，显示两个，然后显示Count

Question

好的，所以我只是一个JSON noob，只有基本的jQuery知识，而且我已经全神贯注地找到了一个解决方案并找不到解决方案。非常感谢任何帮助。

我需要：

1）循环通过JSON数组（工作）

2）显示＆＃34; mbrname＆＃34;

的前两个结果

3）然后显示其余结果的计数。

我成功循环并显示所有mbrname结果。但不知怎的，我只需要显示前两个，如果有更多的显示＆＃34; +＃others＆＃34;

以下是最终产品的截图：

这是我的代码现在生成的内容：

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jquery仅仅是为了＆＃34; mbrname＆＃34;成功提取名称并将其附加到我的HTML的部分：

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

$(currentUser).append(mbrPart);

});

提前感谢您的帮助！

Answer 1

我保持简单，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);

Answer 2

这样的事情应该有效。

var count = 0;
$.each (message.recipient, function (message, recipient) {


if(count<2){
var mbrPart = recipient.mbrname + ', ';
var currentUser = $('#' + newID + ' .name');
$(currentUser).append(mbrPart);
}
count++;
});

$(currentUser).append(" + " + count-2 + " Others");
