Question

给出以下回复：

response=[{"long":"long_value1","lat":"lat_value1","ts":"ts_value"},{"long":"long_value2","lat":"lat_value2","ts":"ts_value"},{"long":"long_value3","lat":"lat_value3","ts":"ts_value"},{"long":"long_value4","lat":"lat_value4","ts":"ts_value"}]

然后使用api，我尝试了下一步来执行此操作，以便插入＆＃34;地址＆＃34;财产回应：

    for(var i in response){
      $http.get(url(i)).success(function(response2){
        response[i].address = response2.valueToassign;        
                });
}

我的问题是＆＃34;地址＆＃34; property仅在最后一个对象中插入，如下所示：

 response=[{"long":"long_value1","lat":"lat_value1","ts":"ts_value"},{"long":"long_value2","lat":"lat_value2","ts":"ts_value"},{"long":"long_value3","lat":"lat_value3","ts":"ts_value"},{"long":"long_value4","lat":"lat_value4","ts":"ts_value", "address":"address_value4}]

此循环如何插入＆＃34;地址＆＃34;在数组的每个对象中？

代码的问题在于它在循环执行之前是异步的试试这个

        var responses = [{"long":"long_value1","lat":"lat_value1","ts":"ts_value"},{"long":"long_value2","lat":"lat_value2","ts":"ts_value"},{"long":"long_value3","lat":"lat_value3","ts":"ts_value"},{"long":"long_value4","lat":"lat_value4","ts":"ts_value"}]

            function uploader(i){
            if(i< responses.length)
            {
            $http.get(url).success(function(response2){
                           if(response2){
                    response[i].address = response2.valueToassign; 
                  uploader(i+1) 
    }
    else{
         alert('resposnse output is blank');
         uploader(i+1)
      }    
 });

            }
            else{
            console.log(response);
            }
            }
            uploader(0)
