javascript - 如果条件为真，则将键添加到散列

Question

我有这个代码:

function myFunction(serializeData, extraSerializedData){
  //serializeData is boolean
  var    formSerializedData = '';
  if(serializeData){
      var formSerializedData = $("#myform").serialize();
      if (typeof extraSerializedData !== 'undefined'){
        formSerializedData += extraSerializedData;
      }
    }

    $.ajax({
      type: "get",
      url: "/123",
      data: formSerializedData, //TODO!!!       
      success: function(data){
        //......

只有 serializeData 存在时，我才想添加 data 键。是否有可能以及如何以代码保持“美观”的方式做到这一点？

我建议，尽管未经测试:

$.ajax({
      type: "get",
      url: "/123",
      data: serializeData !== undefined ? formSerializedData : null,
      success: function(data){
        //......
      }
});
