中构建html元素。
我需要我的程序在每个类别下构建按钮，现在我的代码有问题构建按钮。我也不知道如何在各自的类别下组织按钮。
<h1>Category 1</h1>
<h1>Category 2</h1>
<div class="buttonDiv"></div>
<script type="text/javascript">
//start game code
var buttonArr = [
{ "category":"Action","name":"Temple Run 2","url":"https://bigfoot9999.github.io/html5-games/games/templerun2/"},
{ "category":"Action","name":"Slope Game","url":"https://bigfoot9999.github.io/Slope-Game/"}
]
buttonArr.forEach(function (arrayItem) {
console.log(arrayItem.name);
console.log(arrayItem.url);
document.getElementById('buttonDiv').innerHTML += "<button onClick='openGame(arrayItem.url)'>arrayItem.name</button>";
},);
//end game code
let win;
function openGame(url) {
if (win) {
win.focus();
return;
}
win = window.open();
win.document.body.style.margin = '0';
win.document.body.style.height = '100vh';
const iframe = win.document.createElement('iframe');
iframe.style.border = 'none';
iframe.style.width = '100%';
iframe.style.height = '100%';
iframe.style.margin = '0';
iframe.src = url;
win.document.body.appendChild(iframe);
}
</script><h1>Category 1</h1>
<h1>Category 2</h1>
<div id="buttonDiv"></div>
<script type="text/javascript">
//start game code
var buttonArr = [
{ "category":"Action","name":"Temple Run 2","url":"https://bigfoot9999.github.io/html5-games/games/templerun2/"},
{ "category":"Action","name":"Slope Game","url":"https://bigfoot9999.github.io/Slope-Game/"}
]
buttonArr.forEach(function (arrayItem) {
console.log(arrayItem.name);
console.log(arrayItem.url);
document.getElementById('buttonDiv').innerHTML += `<button onClick='openGame(${arrayItem.url})'>${arrayItem.name}</button>`;
},);
//end game code
let win;
function openGame(url) {
if (win) {
win.focus();
return;
}
win = window.open();
win.document.body.style.margin = '0';
win.document.body.style.height = '100vh';
const iframe = win.document.createElement('iframe');
iframe.style.border = 'none';
iframe.style.width = '100%';
iframe.style.height = '100%';
iframe.style.margin = '0';
iframe.src = url;
win.document.body.appendChild(iframe);
}
</script>你给buttonDiv分配了class属性，我把它改成了buttonDiv的id属性。我在创建按钮时也使用了模板字符串，因为模板字符串允许我们以以下格式编写表达式${variable/expression}
<h1>Category 1</h1>
<h1>Category 2</h1>
<div id="buttonDiv"></div>
<script type="text/javascript">
//start game code
var buttonArr = [
{ "category":"Action","name":"Temple Run 2","url":"https://bigfoot9999.github.io/html5-games/games/templerun2/"},
{ "category":"Action","name":"Slope Game","url":"https://bigfoot9999.github.io/Slope-Game/"}
]
buttonArr.forEach(function (arrayItem) {
console.log(arrayItem.name);
console.log(arrayItem.url);
document.getElementById('buttonDiv').innerHTML += `<button onClick='openGame(${arrayItem.url})'>${arrayItem.name}</button>`;
},);
//end game code
let win;
function openGame(url) {
if (win) {
win.focus();
return;
}
win = window.open();
win.document.body.style.margin = '0';
win.document.body.style.height = '100vh';
const iframe = win.document.createElement('iframe');
iframe.style.border = 'none';
iframe.style.width = '100%';
iframe.style.height = '100%';
iframe.style.margin = '0';
iframe.src = url;
win.document.body.appendChild(iframe);
