如何在弹出窗口中 select 一种语言 (English/French)?

How to select a language (English/French) in a popup?

<body style="text-align:center">

<h2>Popup</h2>

<div class="popup" onclick="myFunction()">Click me to toggle the popup!
  <span class="popuptext" id="myPopup">A Simple Popup!</span>
</div>

<script>
// When the user clicks on div, open the popup
function myFunction() {
    var popup = document.getElementById('myPopup');
    popup.classList.toggle('show');
}
</script>

</body>

我正在尝试以如下图所示的方式制作弹出窗口,并按照 w3shools link 中的程序进行操作,如果有人点击:

Click me toggle the popup

它应该显示:

英语(如果页面显示法语)

法语(如果页面显示英语)

单击英语将以英语显示整个网页,单击法语将以法语显示整个网页。我已经有一个 JS 文件,其中每个文本都从英语翻译成法语,然后从法语翻译成英语。它的片段是:

define([],function(){
var exports = {
//////////////////////////////////
// Enter each key value pair as //
// "key" : "value" ,            //
//////////////////////////////////
// Do not edit above this line  //
//////////////////////////////////
"unspecified": "Unspecified",
"yes": "Yes",
"no": "No",
"error.notify": "An error has occurred. Please contact your plan administrator.",
"error.application": "Error: 500",

"english": "English",
"french": "French",

"m": "Male",
"f": "Female",

"smoker": "smoker",
"non-smoker": "non-smoker",
//////////////////////////////////
// Do not edit below this line  //
//////////////////////////////////
};
return exports;
});

类似这样的东西?

function myFunction() {
  var popup = document.getElementById('myPopup');
  popup.classList.toggle('show')
  if (!popup.classList.toggle('show')) {
    if (popup.innerHTML == "English") {
      popup.innerHTML = "French";
      popup.classList.toggle('show')
    } else {
      popup.innerHTML = "English";
      popup.classList.toggle('show')
    }
  } else {
    popup.classList.toggle('show');
  }
}
/* Popup container - can be anything you want */

.popup {
  position: relative;
  display: inline-block;
  cursor: pointer;
  -webkit-user-select: none;

  margin-left: -5px;
  border-width: 5px;

}
/* Toggle this class - hide and show the popup */

.popup .show {
  visibility: visible;
  -webkit-animation: fadeIn 1s;
  animation: fadeIn 1s;
}
/* Add animation (fade in the popup) */

@-webkit-keyframes fadeIn {
  from {
    opacity: 0;
  }
  to {
    opacity: 1;
  }
}
@keyframes fadeIn {
  from {
    opacity: 0;
  }
  to {
    opacity: 1;
  }
}
<h2>Popup</h2>
