使用Xterm实现终端构建

————html篇————

// 需要使用Xterm

Xterm的官网：

Xterm.js

新建项目

增加基本文件

下载

框架

npm init -y

Xterm依赖

 npm install @xterm/xterm

参考文档写的代码

贴入代码

 <html><head><link rel="stylesheet" href="node_modules/@xterm/xterm/css/xterm.css" /><script src="node_modules/@xterm/xterm/lib/xterm.js"></script></head><body><div id="terminal"></div><script>var term = new Terminal();term.open(document.getElementById('terminal'));term.write('Hello from \x1B[1;3;31mxterm.js\x1B[0m $ ')</script></body></html>

此时启动后发现无法输入

设置画布颜色，输入删除等

<html><head><link rel="stylesheet" href="node_modules/@xterm/xterm/css/xterm.css" /><script src="node_modules/@xterm/xterm/lib/xterm.js"></script></head><body><div id="terminal"></div><script>var rows = rows || 36;var cols = cols || 80;var term = new Terminal({rendererType: "canvas", //渲染类型convertEol: true, //启用时，光标将设置为下一行的开头scrollback: 100, //终端中的回滚量disableStdin: false, //是否应禁用输入。cursorStyle: "underline", //光标样式cursorBlink: true, //光标闪烁cols: cols,rows: rows,theme: {foreground: "#14e264", //字体background: "#002833", //背景色cursor: "help", //设置光标lineHeight: 16},bellStyle: 'sound',rightClickSelectsWord: true,screenReaderMode: true,allowProposedApi: true,LogLevel: 'debug',});console.log(term)term.onData((data) => {const printable = data.match(/[\x20-\x7E]/); // 匹配可打印字符的正则表达式if (data === '\r' || data === '\x0D') {// 处理回车键，添加换行term.writeln('');/*** 这里将输入的指令发到后端进行处理* */} else if (data === '\x08' || data === '\x7F') {// 处理退格键，删除最后一个字符term.write('\b \b');} else if (printable) {// 处理可打印字符term.write(data);}});term.open(document.getElementById('terminal'));term.write('Hello from \x1B[1;3;31mxterm.js\x1B[0m $ ')</script>
</body></html>
