基本上，你会得到makeTransliteratable个代码并将其放入一个方法中.在那之后，你可以对任何你想使其可翻译的输入调用这样的方法.

不过也有一些trap .

第一个问题是如何判断谷歌音译是否已加载.我在方法中使用了Promise(window.googleIsloaded)和await window.googleIsLoaded;来保证只加载了after个google.

第二个问题要糟糕得多:当进行音译时，谷歌直接设置<input>的值，这样做时不会发出任何事件.由于没有事件，Vue无法更新v-model属性.为了克服这一点，我创建了一个Proxy，它可以拦截对输入的任何调用，并在谷歌直接设置值时发出一个输入事件，从而允许Vue获取更改.缺点是Proxy API是not available in IE.

JSFiddle demo here.

Update:

好吧，我想出了一个work in all IE versions Vue support的解决方案，也能把它变成Vue 100.

所以你所要做的就是在<input>或<textarea>中加上v-transliterate="options"，即options，你的对象或属性包含特定<input>/<textarea>的音译配置.例子:

<input type="text" v-model="somevar" v-transliterate="options">

Demo JSFiddle here.代码:

<script src="https://unpkg.com/vue"></script>
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script>
  // Load the Google Transliterate API
  google.load("elements", "1", {
    packages: "transliteration"
  });

  Vue.directive('transliterate', function (el, binding) {
      var control = new google.elements.transliteration.TransliterationControl(binding.value);
      // a getter for each property google transliterate reads and a setter for each it modifies
      var inputOrTextareaProxy = {
          get getAttribute() { return el.getAttribute.bind(el); },
          get addEventListener() { return el.addEventListener.bind(el); },
          get blur() { return el.blur.bind(el); },
          get focus() { return el.focus.bind(el); },
          get tagName() { return el.tagName; },
          get type() { return el.type; },
          get id() { return el.id; },
          get style() { return el.style; },
          get selectionStart() { return el.selectionStart; },
          get selectionEnd() { return el.selectionEnd; },
          get value() { return el.value; },
          set value(v) { el.value = v; el.dispatchEvent(new CustomEvent('input')); },
          get nodeType() { return el.nodeType; },
          get ownerDocument() { return el.ownerDocument; },
          get scrollTop() { return el.scrollTop; },
          set scrollTop(v) { el.scrollTop = v; }
      };
      control.makeTransliteratable([inputOrTextareaProxy]);
  });
