js实现pdf文件路径预览和下载

预览
直接浏览器窗口打开默认就是预览

window.open('文件路径')

下载

function downloadPDF(url, filename) {fetch(url).then(response => response.blob()).then(blob => {const link = document.createElement('a');link.href = URL.createObjectURL(blob);link.download = filename;document.body.appendChild(link);link.click();document.body.removeChild(link);}).catch(error => console.error('Error downloading PDF:', error));
}
//调用
downloadPDF('文件路径','文件名.pdf')
