HomeWeb Front-endJS TutorialJavascript obtains unified management prompts (message)_javascript skills

 
项目开发中,各个页面,各个业务操作都会使用提示语。面对这么多message,更好的方式是统一管理这些消息。这样在做国际化的时候进行统一处理也变的方便。

推荐方案使用数据库来管理所有提示语,在项目启动的时候将所有提示语加载到内存或缓存存储。

对于Java中如何实现,没有什么可说的,很简单。那么我们如何在Javascript中使用我们这些提示语呢,下面进行了简单封装,思路清晰,使用简单,供大家参考。

1、创建message.jsp,代码如下:

<%-- <%@ page import="com.xxx.xxx.xxx.xxx.I18nManager" %> --%>
<%@ page language="java" pageEncoding="UTF-8"%>
function I18nManager() {
this.init;
this.messages;
};
I18nManager.prototype = {
get : function(id, args) {
if (!this.init) {
this.messages = new Array();
// 这里可以使用Java代码的方法读取服务端已经缓存好的消息提示语
<%-- this.messages['charset'] = "<%= I18nManager.get(user, "charset") %>"; --%>
<%-- this.messages[''] = "<%= I18nManager.get(user, "") %>"; --%>
<%-- this.messages['M0001'] = "<%= I18nManager.get(user, "M0001") %>"; --%>
<%-- this.messages['M0002'] = "<%= I18nManager.get(user, "M0002") %>"; --%>
<%-- this.messages['M0003'] = "<%= I18nManager.get(user, "M0003") %>"; --%>
<%-- this.messages['M0004'] = "<%= I18nManager.get(user, "M0004") %>"; --%>
<%-- this.messages['M0005'] = "<%= I18nManager.get(user, "M0005") %>"; --%>
<%-- this.messages['M0006'] = "<%= I18nManager.get(user, "M0006") %>"; --%>
<%-- this.messages['ui.title.user'] = "<%= I18nManager.get(user, "ui.title.user") %>"; --%>
<%-- this.messages['ui.title.xview'] = "<%= I18nManager.get(user, "ui.title.xview") %>"; --%>
<%-- this.messages['ui.title.xview.memo'] = "<%= I18nManager.get(user, "ui.title.xview.memo") %>"; --%>
<%-- this.messages['ui.title.xviewPointList'] = "<%= I18nManager.get(user, "ui.title.xviewPointList") %>"; --%>
<%-- this.messages['ui.title.sherpaOracle'] = "<%= I18nManager.get(user, "ui.title.sherpaOracle") %>"; --%>
// 或者可以静态设置一些提示语
this.messages['M0001'] = "操作成功!"; 
this.messages['M0001'] = "操作失败!"; 
this.init = true;
}
var message = this.messages[id];
if (!message && message !== "") {
return id;
}
if (args) {
if (typeof args == "object" && args.length) {
for (var i = 0; i < args.length; i++) {
var pattern = new RegExp("\\{" + i + "\\}", "g"); 
message = message.replace(pattern, args[i]);
}
} else {
message = message.replace(/\{0\}/g, args);
}
}
return message;
},
alert : function(id, args) {
alert(this.get(id, args));
}
};
var i18n = new I18nManager();

代码中的“操作成功” 和 “操作失败” 是我静态写死的值。我们在jsp中使用动态Java代码读取服务端在系统启动后已经全部缓存好的所有消息提示语,并将其动态输出设置到 this.message[‘xxxx'] 中。

2、如何在页面中使用

window.onload = function(){
i18n.alert('M0001');
//alert(i18n.get('M0001'));
}

可以使用我们定义好的 get 和 alert 方法直接使用,当然根据实际需要,我们可以扩展自己的方法。

JavaScript core data types are consistent in browsers and Node.js, but are handled differently from the extra types. 1) The global object is window in the browser and global in Node.js. 2) Node.js' unique Buffer object, used to process binary data. 3) There are also differences in performance and time processing, and the code needs to be adjusted according to the environment.

Python vs. JavaScript: A Comparative Analysis for DevelopersPython vs. JavaScript: A Comparative Analysis for DevelopersMay 09, 2025 am 12:22 AM

The main difference between Python and JavaScript is the type system and application scenarios. 1. Python uses dynamic types, suitable for scientific computing and data analysis. 2. JavaScript adopts weak types and is widely used in front-end and full-stack development. The two have their own advantages in asynchronous programming and performance optimization, and should be decided according to project requirements when choosing.

Python vs. JavaScript: Choosing the Right Tool for the JobPython vs. JavaScript: Choosing the Right Tool for the JobMay 08, 2025 am 12:10 AM

Whether to choose Python or JavaScript depends on the project type: 1) Choose Python for data science and automation tasks; 2) Choose JavaScript for front-end and full-stack development. Python is favored for its powerful library in data processing and automation, while JavaScript is indispensable for its advantages in web interaction and full-stack development.

Python and JavaScript each have their own advantages, and the choice depends on project needs and personal preferences. 1. Python is easy to learn, with concise syntax, suitable for data science and back-end development, but has a slow execution speed. 2. JavaScript is everywhere in front-end development and has strong asynchronous programming capabilities. Node.js makes it suitable for full-stack development, but the syntax may be complex and error-prone.

JavaScript can be used for front-end and back-end development. The front-end enhances the user experience through DOM operations, and the back-end handles server tasks through Node.js. 1. Front-end example: Change the content of the web page text. 2. Backend example: Create a Node.js server.
