This article mainly introduces five methods of exporting Excel using JS, and analyzes in detail the relevant operating techniques for exporting Excel files based on table forms based on examples. The source code is also attached for readers to download and refer to. Friends in need can refer to it. Next, I hope it can help everyone.

The first four of these five methods only support the IE browser, and the last method supports the current mainstream browsers (Firefox, IE, Chrome, Opera, Safari)

I came up today and found that many people will encounter problems with file names, formats, etc. Add a method here. I have not tested the compatibility. You can try it, but you need to use JQ to post the code directly. The source code can be found here下载. Note that you must quote the files corresponding to jquery-3.2.1.min.js and jquery.table2excel.js. jquery-3.2.1.min.js depends on your corresponding file version, it doesn’t matter. If you have any questions, criticism and guidance are welcome.
