注意:导出其他格式文件可能会出现乱码问题,如有好的解决方案请留言

<!--调用FileSaver saveAs函数可以实现文件下载-->

<script>
//如果使用 FileSaver.js 就不要同时使用以下函数
function saveAs(obj, fileName) {//当然可以自定义简单的下载文件实现方式
var tmpa = document.createElement("a");
tmpa.download = fileName || "下载";
tmpa.href = URL.createObjectURL(obj); //绑定a标签
tmpa.click(); //模拟点击实现下载
