我想在用户点击按钮时同时更改两个HTML元素的内容。元素的内容更改为基于随机数,然后将访问函数中定义的数组。
这就是我想要发生的事情,但是当我点击按钮(调用' deal()'功能)时,我目前没有得到任何改变。 / p>
有人可以给我任何建议吗?
这是我的代码 -
function createCard(){
var shuffle = Math.floor(Math.random()*2) +1;
var title = document.getElementById("cardTitle");
var text = document.getElementById('cardText');
var button = document.getElementById('cardButton');
var cardTitle = ["Bacon", "Hot Dog Lattice"];
var cardText = ['Frabdious Day', 'Calee, Calay',];
var cardId = [cardTitle, cardText];
switch (shuffle) {
case 1:
title.innerHTML = cardId(cardTitle[0]);
text.innerHTML = cardId(cardText[0]);
break;
case 2:
title.innerHTML = cardId(cardTitle[1]);
text.innerHTML = cardId(cardText[1]);
break;
default:
title.innerHTML = "Oops";
text.innerHTML = "Whoopsie";
break;
}
}
function deal(){
createCard();
}
答案 0 :(得分:0)
这可能是一个更好的解决方案:
function createCard(){
var shuffle = Math.floor(Math.random()*2);
var cards = [
{
title: "Bacon",
text: "Frabdious Day"
},
{
title: "Hot Dog Lattice",
text: "Calee, Calay"
}
];
var shuffledCard = cards[shuffle];
if (!shuffledCard){
shuffledCard = {
title: "Oops",
text: "Whoopsie"
}
}
var title = document.getElementById("cardTitle");
var text = document.getElementById('cardText');
var button = document.getElementById('cardButton');
title.innerHTML = shuffledCard.title;
text.innerHTML = shuffledCard.text;
}
function deal(){
createCard();
}
<div id="cardTitle">Start value</div>
<div id="cardText">Start value</div>
<button id="cardButton" onClick="deal()">Deal</button>
