如何解决单击按钮时如何更改const值?
有人可以帮助我用可以帮助我根据单击哪个按钮来更改player.choice值的东西替换console.log行吗?
const player = {
currentChoice: null
}
const computer = {
currentChoice: null
}
const choices = ["Lapis","Papyrus","Scalpellus"];
document.querySelector('#Lapis').onclick = setLapis
document.querySelector('#Papyrus').onclick = setPapyrus
document.querySelector('#Scalpellus').onclick = setScalpellus;
function setLapis(){
console.log("Lapis");
}
function setPapyrus(){
console.log("Papyrus");
}
function setScalpellus(){
console.log("Scalpellus");
}
player.currentChoice = choices[0];
<button id="Lapis">Lapis</button>
<button id="Papyrus">Papyrus</button>
<button id="Scalpellus">Scalpellus</button>
解决方法
const player = {
currentChoice: null
}
const computer = {
currentChoice: null
}
const choices = ["Lapis","Papyrus","Scalpellus"];
document.querySelector('#Lapis').onclick = setLapis
document.querySelector('#Papyrus').onclick = setPapyrus
document.querySelector('#Scalpellus').onclick = setScalpellus;
function setLapis(){
player.currentChoice = choices[0];
console.log(player.currentChoice);
}
function setPapyrus(){
player.currentChoice = choices[1];
console.log(player.currentChoice);
}
function setScalpellus(){
player.currentChoice = choices[2];
console.log(player.currentChoice);
}
<button id="Lapis">Lapis</button>
<button id="Papyrus">Papyrus</button>
<button id="Scalpellus">Scalpellus</button>
