js保存文本文件

function saveTextAsFile(text, fileName) {
    // 创建一个Blob对象
    const blob = new Blob([text], { type: 'text/plain' });
    
    // 创建一个指向Blob对象的URL
    const url = URL.createObjectURL(blob);
    
    // 创建一个a标签
    const a = document.createElement('a');
    a.href = url;
    a.download = fileName;
    
    // 触发点击事件下载文件
    document.body.appendChild(a);
    a.click();
    
    // 清理
    document.body.removeChild(a);
    URL.revokeObjectURL(url);
}

// 使用示例
const textToSave = "Hello, world!";
const fileNameToSaveAs = "hello.txt";
saveTextAsFile(textToSave, fileNameToSaveAs);
