如何將數據對象添加到JSON對象？

我想將列表2的數據[]添加到列表1作爲子項。期望的輸出是列表3.但是用我的代碼，我得到空字符串作爲孩子的值。在_getJsonObject(id,user) API調用帶來清單2.如何將數據對象添加到JSON對象？

我長相的代碼如下：

var strList = function(){ 
    var listItems= ""; 
    $.ajax({ 
     url: 'http://localhost:8088/api/v1/ui/performance/custom_link_groups?', 
     dataType: 'json', 
     async: false, 
     success: function(data){ 
      for (var i = 0; i < data.data.length; i++){ 
       data.data[i].children = _getJsonObject(data.data[i].$ID,data.data[i].$userId); 
      } 
      listItems = data; 
     } 
    }); 
    return listItems; 
}(); 


function _getJsonObject(id,user){ 
    var rdata = ""; 
    $.ajax({ 
     url: 'http://localhost:8088/api/v1/ui/performance/custom_links?group='+id+'&user='+user, 
     dataType: 'json', 
     async: false, 
     success: function(data){ 
      rdata = data.data; 
     } 
    }); 
    return rdata; 
}

表1

"error_code": "",

你需要使用回調並執行了AJAX調用已經結束，否則你是從_getJsonObject返回Ajax調用結束前。使用回調函數作爲該函數的第三個參數，並在使用data.data對該回調函數進行ajax請求調用的成功回調函數中使用。 – satchcoder 2015-02-09 10:21:24

即使使用'async：false'，return語句也會在AJAX回調之前執行。 – 2015-02-09 10:21:41

var strList = function (callback){ 
var listItems= ""; 
$.ajax({ 
    url: 'http://localhost:8088/api/v1/ui/performance/custom_link_groups?', 
    dataType: 'json', 
    async: false, 
    success: function(data){ 
     for (var i = 0; i < data.data.length; i++){ 
      _getJsonObject(data.data[i].$ID,data.data[i].$userId,   

      function(data) 
      { 
       data.data[i].children = data; 
      }); 
      } 
      callback(data); 
     } 
    }); 
    return listItems; 
}(); 


function _getJsonObject(id,user, callback){ 
    var rdata = ""; 
    $.ajax({ 
     url: 'http://localhost:8088/api/v1/ui/performance/custom_links?group='+id+'&user='+user, 
     dataType: 'json', 
     async: false, 
     success: function(data){ 
      callback(data.data); 
     } 
    }); 
    return rdata; 
}
