JS | Onload和Onclick不能一起工作-快速解决方案?

onload innerhtml onclick function javascript

Adam · 技术社区 · 7 年前

问题可能在于两个事件: onload , onclick 空载 确实有效,但没有)。我如何才能以最好的方式解决这个问题,使其中两个在同一代码中运行?谢谢你的建议。

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 click 是本机函数。因此,您的点击处理程序正在工作,但它正在调用内置的 点击 功能,而不是单击功能。您可以通过重命名函数来修复此问题。例如,我给它命名 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";
}
