JS | Onload 与 Onclick 不能协同工作 - 快速解决方案？

Question

问题可能出在两个事件上：onload、onclick（事件onload有效，但onclick无效）。我怎样才能以最好的方式解决这个问题，让它们中的两个运行保持在同一代码中？感谢您的任何建议。

const vacationPlaces = ['Praha','Vien','Munich'];

function backwards() {
for (let vacationSpotIndex = vacationPlaces.length - 1; vacationSpotIndex >= 0; vacationSpotIndex--) {
    let showPlaces = vacationPlaces[vacationSpotIndex] + ", ";
    let removeComma = showPlaces;
    document.getElementById("resultMonthly").innerHTML += removeComma;
 }
}

function forwards() {
for (let i = 0; i < vacationPlaces.length; i++) {
    document.getElementById("resultDaily").innerHTML += vacationPlaces[i] + ", ";
 }
}



function all() {
    backwards();
    forwards();
}

function click() {
    document.getElementById("resultHourly").innerHTML = "hi";
}

在 onclick 属性的上下文中，函数 click 是本机函数。所以您的点击处理程序正在运行，但它调用的是内置 click 函数，而不是您的点击函数。您可以通过重命名函数来解决这个问题。比如我命名为showAlert:

const vacationPlaces = ['Praha','Vien','Munich'];

function backwards() {
  for (let vacationSpotIndex = vacationPlaces.length - 1; vacationSpotIndex >= 0; vacationSpotIndex--) {
    let showPlaces = vacationPlaces[vacationSpotIndex] + ", ";
    let removeComma = showPlaces;
    document.getElementById("resultMonthly").innerHTML += removeComma;
  }
}

function forwards() {
  for (let i = 0; i < vacationPlaces.length; i++) {
    document.getElementById("resultDaily").innerHTML += vacationPlaces[i] + ", ";
  }
}

function all() {
  backwards();
  forwards();
}

function showAlert() {
  console.log('clicked')
  document.getElementById("resultHourly").innerHTML = "hi";
}
