如何在javascript中从一个ajax函数访问变量到另一个函数

Question

这是视图文件脚本代码功能

function getState(val) { 
  $.ajax({
    url: "{{ URL::to('admin/state_change') }}" + "/" + val, //url route 
    controller in route.php
    type: "GET",
    dataType: "json",
    success: function (data) {
      var lid = data.lawid;             //getting value from controller
      var scn = data.sortname;          //getting value from controller
      var finlawid = 'L'+scn+'C'+lid;   //concatinating
      $("#lm_id").val(finlawid);        // Lm_id is textbox id
    }
  });
}

我想在下面的函数中访问一个scn变量的盖子，它存在于同一个文件中

function getStatename(val) {
  if (val >= 0) {
    // access lid and scn to concatinat more characters and assigned it to lm_id textbox
  }
}
