问题描述
我最近偶然发现此JSFiddle关于如何直接将表转换为Excel 文件花哨的插件.它确实适合我的需要,但是有一个缺陷,我无法重命名其文件. Chrome将文件重命名为download
,而Firefox为其随机命名.
I recently stumbled upon this JSFiddle about how to convert a table to Excel file directly without any fancy plugins. It really suits my need, but it has a flaw, I can't rename its file. Chrome renames the file to download
and Firefox gives a random name to it.
$("#btnExport").click(function (e) {
window.title = "filename.xls"; // this part doesn't work
window.open('data:application/vnd.ms-excel,' +
$('#dvData').html());
e.preventDefault();
});
如何重命名下载的文件?
How can I rename the downloaded file ?
推荐答案
使用<a>
元素和download
属性
let file = new Blob([$('#dvData').html()], {type:"application/vnd.ms-excel"});
let url = URL.createObjectURL(file);
let a = $("<a />", {
href: url,
download: "filename.xlsx"
})
.appendTo("body")
.get(0)
.click();
