javascript - jQuery:函数参数在成功回调中未定义

我正在尝试在成功回调中访问graphList，但是graphList是未定义的。我提到了this StackOverflow帖子。但是，我无法访问elem。任何帮助，将不胜感激。

getGraphData = function (graphList) {
 $.ajax({
 type: "GET",
 url: 'someURL',
 beforeSend: function(xhr){},
 success: function(result) {
   console.log(result);
   console.log(graphList);//undefined
 }
});
}

最佳答案

添加了如下所示的创建getGraphList函数，我可以在成功回调中访问getGraphList

var graphList;
var promise = graphInit(response);
promise.done(function(data){
  getGraphData(data.graphs)
}

graphInit = function(response,graphList){
  getGraphList = function(){return response.graphs;}
}

getGraphData = function (graphList) {
  $.ajax({
  type: "GET",
  url: 'someURL',
  beforeSend: function(xhr){},
    success: function(result) {
    console.log(result);
    console.log(graphList);//undefined
    graphList = getGraphList();//available
  }
});
}
