Angular2 i18n(用于占位符文本) [英] Angular2 i18n for placeholder text

问题描述

是否可以使用Angular 2的i18n转换输入文本字段的占位符文本?

Is there a way to translate the placeholder text for an input text field using Angular 2's i18n?

<input placeholder="hello world" i18n>

<input placeholder="hello world" i18n>

我没有在文档中看到任何有关此的内容: https://angular.io/docs/ts/latest/cookbook/i18n.html

I don't see anything in the documentation about this: https://angular.io/docs/ts/latest/cookbook/i18n.html

推荐答案

有一个例子，但我似乎再也找不到了.

There has been an example, but I can't seem to find it anymore.

您应该可以使用i18n-attributename.例如:

You should be able to use i18n-attributename. For example:

<input type="number" placeholder="From" i18n-placeholder="From placeholder"/>

那需要一个这样的条目:

That would need an entry like this:

<trans-unit id="generatedId" datatype="html">
  <source>From</source>
  <target state="translated">Van</target>
  <note priority="1" from="description">From placeholder</note>
</trans-unit>

在您的messages.xlf文件中.如果没有翻译，我无法使它正常工作.因此，您需要添加state = translated和一个值.

In your messages.xlf file. I couldn't get it to work without a translation though. So you will need to add the state=translated and a value.

即使我们没有在 i18n占位符中提供价值，也可以. 只是喜欢:

Even if we don't give value in i18n-placeholder then it is also fine. just do like:

<input type="number" placeholder="From" i18n-placeholder/>

它将正常工作.
