工商银行的网银出现代码为Java Script Error 是什么意思？

工商银行的网银出现代码为Java Script Error 是Java脚本错误，一般是兼容性的问题。一般换台电脑或者换个系统或者更换浏览器即可解决。

Java是一种可以撰写跨平台应用软件的面向对象的程序设计语言。Java 技术具有卓越的通用性、高效性、平台移植性和安全性，广泛应用于PC、数据中心、游戏控制台、科学超级计算机、移动电话和互联网，同时拥有全球最大的开发者专业社群。

脚本（script）是使用一种特定的描述性语言，依据一定的格式编写的可执行文件，又称作宏或批处理文件。脚本是批处理文件的延伸，是一种纯文本保存的程序，一般来说的计算机脚本程序是确定的一系列控制计算机进行运算操作动作的组合，在其中可以实现一定的逻辑分支等。
