将单击按钮文本更改为随机选项

Question

I have around 12 different word that I want to be shown in random order when the user clicks a button. A new one every time they press the Button. Is this possible to do with JS? I've tried the method shown here: Random text on button click

   Random myRandom = new Random();
   TextView textblondin = (TextView) findViewById(R.id.textblondin);
   switch(myRandom.nextInt() %3) {
      case 0:
         textblondin.setText("Text 1");
         break;
      case 1:
         textblondin.setText("Text 2");
         break;
      case 2:
     textblondin.setText("Text 3");
     break;
      default:
     break;
   }
}
}   

Would appreciate any help that points me in the right direction. I'm new to Javascript.

Try this as your HTML:

<button onclick="randomWord()">
 Random Word
</button>
<div id="word">
  Click to display a random word
</div>

And this as your JS:

let randomWords = [ 'foo', 'bar' ];
let wordDiv = document.getElementById( 'word' );

function randomWord() {
    wordDiv.innerHTML = randomWords[ Math.floor(  Math.random() * randomWords.length ) ];
}

When you click the button it will find a random value from your array and set the div with ID "word" to this value. You can change the values in the randomWords array to whatever you like.
