i18n模型无法正常工作 [英] i18n model doesn't work properly

问题描述

我有一个代码，用于检查服务器的响应并根据收到的信息显示消息框.我有2种语言的这些消息(用户在登录时选择一种语言). 这是示例:

I have a code that checks a response from a server and shows message box according to the information received. I have these messages in 2 languages (user selects a language during login). Here is example:

if(sResponse == 'IDfail'){
    sap.m.MessageBox.alert
    ("{i18nResourceModel>idnotnine}", 
        {icon: sap.m.MessageBox.Icon.ERROR,
        title: "{i18nResourceModel>error}"}
    );
}

这是i18n模型声明(当然是在使用模型之前声明的):

Here is i18n model declaration (it is declared before I use the model, of course):

var oResourceModel = new sap.ui.model.resource.ResourceModel
    ({bundleUrl: "i18n/i18n.properties", bundleLocale: "en"});
sap.ui.getCore().setModel(oResourceModel, "i18nResourceModel");

我有2个.properties文件:i18n.properties(英语)和i18n_iw.properties(希伯来语).

I have 2 .properties files: i18n.properties (english) and i18n_iw.properties (hebrew).

奇怪的是，消息框的title正确翻译了，但是我看到的不是消息本身，而是文本:"i18nResourceModel> idnotnine".

The strange thing is that the title of the message box is translated correctly, but instead of the message itself I see text: "i18nResourceModel>idnotnine".

以前效果很好，我不知道发生了什么事.

It worked fine before and I can't figure out what happened.

可能是什么原因导致此问题，以及如何解决?

What may be causing this issue and how do I fix it?

谢谢.

推荐答案

数据绑定通常在sap.m.MessageBox.alert()之类的函数调用中不起作用.您必须手动获取文本，例如:

Databinding is usually not working in a function call like sap.m.MessageBox.alert(). You have to get the text manually like:

var resourceModel = sap.ui.getCore().getModel("i18nResourceModel");
var alertText = resourceModel.getProperty("idnotnine");
var alertTitle = resourceModel.getProperty("error");

sap.m.MessageBox.alert(alertText, {
          icon: sap.m.MessageBox.Icon.ERROR,
          title: alertTitle 
      }
);
