我想知道如何在点击时更改数据属性。我想要做的是增加25的值。所以我有一个进度条和一个按钮。眼下进度条具有25的值。当我点击按钮,我想它递增到50,75,100点击更改数据属性
下面是代码:
let button = document.getElementById("btn");
let bar = document.getElementById("progress-bar");
button.addEventListener('click', function(){
console.log("you clicked the btn");
});
body {
max-width: 1200px;
margin: 0 auto;
padding: 10px;
display: -webkit-box;
display: -ms-flexbox;
display: flex;
-ms-flex-wrap: wrap;
flex-wrap: wrap;
margin-top: 3em;
}
progress {
-webkit-appearance: none;
-moz-appearance: none;
appearance: none;
width: 100%;
height: 20px;
}
progress::-webkit-progress-bar {
background-color: #ccc;
width: 100%;
}
progress::-webkit-progress-value {
background-color: orange !important;
}
button {
margin-top: 2em;
background: black;
color: white;
border: none;
padding: .5em 2em;
}
button:hover {
background: #1a1a1a;
}
<body>
<h2>Quiz Progress</h2>
<progress max='100' value='25'></progress>
<button id='btn'>Next</button>
</body>
