转换拼音提示 justep.String.makeFirstPY 非函数的错误

十三先生

将字段fName中的汉字转换为拼音赋予字段fPym时，提升如下错误，请问如何解决？

define(function(require){
        var $ = require("jquery");
        var justep = require("$UI/system/lib/justep");

        var Model = function(){
                this.callParent();
        };

        Model.prototype.mainDataDataChange = function(event){
                var sName = event.source.getValue("fName");
                var sPY = justep.String.makeFirstPY(sName);
                event.source.setValue("fPym",sPY);       
       }

错误提示：
justep.String.makeFirstPY is not a function

justep.String.makeFirstPY(sName);这个是5.2中的写法
现在的版本，要先引用var ChinesePY = require("$UI/system/lib/base/chinesePY");
然后调用ChinesePY.makeFirstPY(sName)
