如何使问题从 studio code.org 上的列表中以随机顺序出现

Question

var questionsList = ["what sense do you use to identify the color of something?", "what sense would you use to tell if someone is wearing perfume? ", "what sense would you use to listen to music? ", "what sense would you use to know if the food is sweet or salty?", "what sense would you use to tell if the blanket is wet or dry?"]; 

onEvent("randomMiddleQuestion", "click", function(updateScreen ) {
  setText("randomMiddleQuestion", "what sense do you use to identify the color of something?");
});


onEvent("randomMiddleQuestion", "click", function() {
  questionsList = randomNumber(0, questionsList.length - 1);
  updateScreen();
});
function updateScreen() {
  setProperty("randomMiddleQuestion", "text", questionsList[index]);
}

我想创建一个 on 事件，当单击文本框时，一组问题以不特定的顺序出现
