一旦你修复了json，它应该看起来像这样，并且像这样工作

＆＃13;

＆＃13;

var jsonData = {
   "XXXX": {
      "name": "Dalvin Nieger",
      "work": {
            "department": {
               "name": "Sales"
            },
            "start_date": "0000-00"
         },
      "link": "http://www.my-site.com/profile.php?id=XXXXX",
      "id": "XXXXXX"
   },
   "XXXXXXX": {
      "name": "Nick Mercer",
      "work": {
            "department": {
               "name": "Marketing"
            },
            "start_date": "0000-00",
            "end_date": "0000-00"
         },
      "link": "http://www.my-site.com/profile.php?id=XXXXXX",
      "id": "XXXXXX"
   }
}
$.each(jsonData,function(id,data){
  var content = '<p>ID : '+id;
  if(typeof data == 'object')
    $.each(data,function(index,value){
        
     if(typeof value == 'object' && index=='work'){
       content += '<br/>'+index+' : '+value.department.name;
      }else
        content += '<br/>'+index+' : '+value;       
    });
  content += '</p>';
  $('#result').append(content);
   
})

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.2/jquery.min.js"></script>

<div id="result">
  </div>
