Javascript obtains unified management prompts (message)_javascript skills

May 16, 2016 pm 03:16 PM

 
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();
Copy after login

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'));
}
Copy after login

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。

Demystifying JavaScript: What It Does and Why It Matters Demystifying JavaScript: What It Does and Why It Matters Apr 09, 2025 am 12:07 AM

JavaScript is the cornerstone of modern web development, and its main functions include event-driven programming, dynamic content generation and asynchronous programming. 1) Event-driven programming allows web pages to change dynamically according to user operations. 2) Dynamic content generation allows page content to be adjusted according to conditions. 3) Asynchronous programming ensures that the user interface is not blocked. JavaScript is widely used in web interaction, single-page application and server-side development, greatly improving the flexibility of user experience and cross-platform development.

Can PowerPoint run JavaScript? Can PowerPoint run JavaScript? Apr 01, 2025 pm 05:17 PM

JavaScript can be run in PowerPoint, and can be implemented by calling external JavaScript files or embedding HTML files through VBA. 1. To use VBA to call JavaScript files, you need to enable macros and have VBA programming knowledge. 2. Embed HTML files containing JavaScript, which are simple and easy to use but are subject to security restrictions. Advantages include extended functions and flexibility, while disadvantages involve security, compatibility and complexity. In practice, attention should be paid to security, compatibility, performance and user experience.
