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')
