I want a JavaScript function to randomly select a sentence from a list of data in the same file and display it when I click a button with an "onclick" event. I'm looking for the simplest way to implement this functionality. Does anyone have an example?

(Just looking around, first time trying JavaScript)

let dataList =["句子1","句子2","句子3","句子4"] let div = document.getElementById('asd') document.getElementsByTagName("button")[0].addEventListener("click",myFunc) function myFunc(){ let x = parseInt(Math.random()* dataList.length ) div.innerHTML = dataList[x] }
