index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Simple dApp</title>
<link rel="stylesheet" href="styles.css">
</head>
<body>
<h1>Simple dApp!</h1>
<label for="storeString">Input Sentences:</label> <br />
<input type="text" placeholder="Enterstring" id="storeString">
<center>
<button class="button-63" role="button" onclick="setStr()">Set String</button>
<button class="button-63" role="button" onclick="getStr()">Get String</button>
</center>
</body>
</html>
<input> 中我们设置了 id="storeString", 稍后设置字符串内容时,会读取网页内容将会用到。设置了两个<button>,用于与区块链交互。
styles.css 用于美化网页,可以完全不用
