htmljs中如何取实际写入的值

Question

我正在使用 following 库在我的测试网站中实现多语言。不过也有一些不足，以我的一点经验难以处理

脚本的工作方式是我们有一种默认语言，它被直接写入 html 并且字典是为其他语言制作的（它们在 js 代码的最后）。除了标题，一切正常。当我们想切换到默认语言时，标题不会改变，只有在重新加载页面后它才会改变。

很有可能，问题出在下面的一段代码（184-186行）：

if (langDict["Title"] != null) {
  document.title = langDict["Title"];
}

我想我们需要添加 else 并以某种方式为其设置一个写入 html 本身的值，而不是在翻译中更改的 js。

我的网站上也有一个反馈表。我希望可以翻译 placeholder 值。怎么做？

我是这样理解的，但这是一个好方法吗？

Answer 1

对于第一个片段，您应该只为 en 添加一个包含 Title 的字典，它会起作用，如下所示：

languative.modifyDictionary("en", {
    Title: "Caption",
});

对于第二个，有更多的工作，因为你的脚本更改 innerHTML，这不适合你的反馈表，因为它只包含没有 innerHTML 的输入元素，所以应相应地修改脚本，如下所示：

var languative;
(function (languative) {
    var phraseIdAttr = "data-phrase-id";

    languative.ignoreTags = {
        img: "<img />",
        br: "<br />",
        hr: "<hr />"
    };

    languative.dictonaries = {
        html: {
            _id: "html",
            _name: "HTML"
        },
        en: {
            _id: "en",
            _name: "English"
        },
        ru: {
            _id: "ru",
            _name: "Русский - Russian"
        },
        de: {
            _id: "de",
            _name: "Deutsche - German"
        }
    };

    languative.selectedDictionary = null;

    function getDictionary(langKey) {
