How to Create a New Folder for Downloading a File

问题

I want to download folder that client side (browser) make.

I considered using File API, but I can't find how to make folder.

For example, some png make from html canvas put one folder, I want to save this folder with download dialog.

I want to use a folder for some file to one folder.and I must download only once.

Please advise me.

html

<a download='folder' href='#' onclick="Download()">download</a>

You can use FSO.js, but be warned that it currently only works in Chrome. Additionally, the folders you create can only really be accessed from within your webapp (for example, you can't choose to write a specific folder on the C drive).

Firstly, You can't really interact with the local system or the server with JavaScript because of security. You can call a server-side script with JavaScript, via AJAX.

If you don't care, you can check out Javascript FSO CreateFolder Method

JavaScript Example...

// initialize ActiveXObject and create an object of Scripting.FileSystemObject.  
var fso = new ActiveXObject("Scripting.FileSystemObject");  

// creates a folder with specified name at the specified location  
fso.CreateFolder("C:\\Temp\\myFolder");  

fso = null;
