呼叫test()時提示未定義

layui.use(['layer', 'form', 'element'], function(){
  var layer = layui.layer
  ,form = layui.form
  ,element = layui.element
    function test(){
    //JS程式碼
    }
});

修改為

layui.use(['layer', 'form', 'element'], function(){
  var layer = layui.layer
  ,form = layui.form
  ,element = layui.element
   window.test = function(){
    //JS程式碼
    }
});
