使用 Microsoft Translator 时,有没有办法删除小部件,但保留翻译?

When using the Microsoft Translator, Is there a way to remove the widget, but retain translation?

我正在使用 Microsoft Translation Widget,我想用它来自动翻译网页而无需用户交互。

问题是,我无法摆脱在 document.ready 上不断弹出或隐藏它的小部件,因为 CSS 和 JS 是从小部件中的 Microsoft 自己的脚本加载的!

有人知道解决这个问题的方法吗?我到处都找遍了,找不到解决办法。

哇,经过一段时间的尝试,我终于实现了你想要的。

它有点难看,因为需要一些解决方法,但它确实有效,take a look at the fiddle

步骤是:

  1. 首先,我们必须覆盖默认的 addEventListener 行为:

    var addEvent = EventTarget.prototype.addEventListener;
    var events = [];
    
    EventTarget.prototype.addEventListener = function(type, listener) {
      addEvent.apply(this, [].slice.call(arguments));
      events.push({
        element: this,
        type: type,
        listener: listener
      });
    }
    
  2. 然后,我们创建一个辅助函数removeEvents。它删除元素的所有事件侦听器。

    var removeEvents = function(el, type) {
      var elEvents = events.filter(function(ev) {
        return ev.element === el && (type ? ev.type === type : true);
      });
    
      for (var i = 0; i < elEvents.length; i++) {
        el.removeEventListener(elEvents[i].type, elEvents[i].listener);
      }
    }
    
  3. 在创建 script 标签时,微软表示:

    var s = d.createElement('script');
    s.type = 'text/javascript';
    s.charset = 'UTF-8';
    s.src = ((location && location.href && location.href.indexOf('https') == 0) ? 'https://ssl.microsofttranslator.com' : 'http://www.microsofttranslator.com') + '/ajax/v3/WidgetV3.ashx?siteData=ueOIGRSKkd965FeEGM5JtQ**&ctf=True&ui=true&settings=Manual&from=';
    var p = d.getElementsByTagName('head')[0] || d.dElement;
    p.insertBefore(s, p.firstChild);
    

    我们必须向 script 添加一个 load 事件侦听器,下面的代码已完整注释:

    s.addEventListener('load', function() {
      // when someone changes the translation, the plugin calls the method TranslateArray
      // then, we save the original method in a variable, and we override it
      var translate = Microsoft.Translator.TranslateArray;
    
      Microsoft.Translator.TranslateArray = function() {
        // we call the original method
        translate.apply(this, [].slice.call(arguments));
    
        // since the translation is not immediately available
        // and we don't have control when it will be
        // I've created a helper function to wait for it
        waitForTranslation(function() {
          // as soon as it is available
          // we get all the elements with an attribute lang 
          [].forEach.call(d.querySelectorAll('[lang]'), function(item, i) {
            // and we remove all the mouseover event listeners of them
            removeEvents(item, 'mouseover');
          });
        });
      }
    
      // this is the helper function which waits for the translation
      function waitForTranslation(cb) {
        // since we don't have control over the translation callback
        // the workaround was to see if the Translating label is visible
        // we keep calling the function, until it's hidden again
        // and then we call our callback
        var visible = d.getElementById('FloaterProgressBar').style.visibility;
        if (visible === 'visible') {
          setTimeout(function() {
            waitForTranslation(cb);
          }, 0);
          return;
        }
        cb();
      }
    });
    

更新 1

重新阅读您的问题后,您似乎想要隐藏所有小部件。

因此,您必须在翻译完成后立即添加以下代码:

waitForTranslation(function() {
  document.getElementById('MicrosoftTranslatorWidget').style.display = 'none';
  document.getElementById('WidgetLauncher').style.display = 'none';
  document.getElementById('LauncherTranslatePhrase').style.display = 'none';
  document.getElementById('TranslateSpan').style.display = 'none';
  document.getElementById('LauncherLogo').style.display = 'none';
  document.getElementById('WidgetFloaterPanels').style.display = 'none';
  // rest of the code
});

我创建了 another fiddle for you,展示了新的行为。

更新 2

您可以通过添加以下 CSS 代码完全阻止小部件显示:

#MicrosoftTranslatorWidget, #WidgetLauncher, #LauncherTranslatePhrase, #TranslateSpan, #LauncherLogo, #WidgetFloaterPanels {
    opacity: 0!important;
}

您甚至可以通过默认隐藏 document.body,然后在页面完全翻译后显示它来阻止显示之前翻译的文本:

(function(w, d) {
  document.body.style.display = 'none';
  /* (...) */

  s.addEventListener('load', function() {
    var translate = Microsoft.Translator.TranslateArray;

    Microsoft.Translator.TranslateArray = function() {
      translate.apply(this, [].slice.call(arguments));

      waitForTranslation(function() {
        /* (...) */
        document.body.style.display = 'block';
      });
    }
  });
});

看看at the final fiddle I've created.

对我来说,这是解决方案: 在你的
