javascript - 从 JavaScript 数组中获取随机值（单击按钮）

问题描述

let text = ["hello", "world", "where", "list", "tes", "new"];
const btn = document.querySelector(".button");

btn.addEventListener("click", random);
const randomText = Math.floor(Math.random() * text.length);

function random() {
  const pText = document.querySelector(".p-text");
  const textRandom = (pText.innerHTML = `${text[randomText]}`);
}

嗨，伙计们，你能帮帮我吗？单击按钮时如何仍然获得随机结果？

标签： javascriptarraysfunction

解决方案

function random() {
  const pText = document.querySelector(".p-text");
  // move your randomText into function, so that it will have new value when the function is called.
  const randomText = Math.floor(Math.random() * text.length);
  const textRandom = (pText.innerHTML = `${text[randomText]}`);
}
