How can I make a greasemonkey script to automatically download a file?

Question

I go to the page, I have 1 zip file, but I do not know it except for its .zip .

I want Greasemonkey to download this ZIP file automatically, perhaps using flashgot or something like that?

So I need to activate page loading, then find *.zip and add it to load automatically.

Any ideas?

Answer 1

Greasemonkey alone cannot automatically save zip files or anything else on the local file system.
It is by design; allowing a user / JavaScript page to save files is a proven security risk.

Your options:

• At Greasemonkey, select the correct link and open the "Save File" dialog box (save the search efforts and click "1 click").
• Have GM relay the zip file to your own server . Then your server application will automatically save the file.
  Please note that the “server” may be your own machine running something like XAMPP .
• Write your own Firefox add-on .

Option 1, GM only:

What GM can do is open the File-Save dialog for the correct file:

User interaction will still be required if only one click away.

For example, suppose a page contains this link:

 <a href="http://Suspicious.com/TotallyOwnYourBankAndCreditCardAccounts.zip"> Click me, sucka! </a> 

Then this code will open the File-Save dialog for it:

 var clickEvent = document.createEvent ('MouseEvents'); var firstZipFile = document.querySelector ("a[href*='.zip']"); clickEvent.initEvent ('click', true, true); firstZipFile.dispatchEvent (clickEvent); 

Option 2, GM and your own server application:

Greasemonkey can use GM_xmlhttpRequest () to send files to your web application - which you will have to write >. After that, the web application will automatically save the file to the server. You can configure the local computer on the server.

Option 3, write your own FF extension (add-on):

If you decide to use the optional Firefox route, see MDN: Download Files .

Answer 2

This is the code I used in greasmonkey to download the zip file from the location specified by url in the @include statement.

 // ==UserScript== // @name zipexport // @namespace refresh page // @include https://control.com/export.php // @version 1 // @grant none // ==/UserScript== var timerVar= setInterval(function() {DoMeEverySecond (); }, 60000); function DoMeEverySecond () { setInterval('window.location.reload()',10000); $(document).ready(function() { setTimeout(function(){ document.getElementsByClassName("btn btn-lg btn-primary")[0].click(); }, 1000);}); } 

To understand, please go through this.

 // @include https://control.com/export.php 

Use the link to the source page here

 setInterval(function() {DoMeEverySecond (); }, 60000); 

Helps you call the DoMeEverySecond () function; after 60,000 ms (60 s = 1 min)

 setInterval('window.location.reload()',10000); 

Used to reload the page every 10 seconds. It is used by me only to ensure that the web page is updated to the last state (I had a download file that was updated every hour). You can avoid it if you do not need it.

 $(document).ready(function() 

function () is only called after a full reload of the web page, if we use this statement.

 document.getElementsByClassName("btn btn-lg btn-primary")[0].click(); 

getElementsByClassName / getElementsById etc. can be used here, based on what can point to the file you want to download (use the check item by right-clicking on the source page to find out if any of the / id class can point to your zip file)

[0] can help you if you have several variables to call in the same class.

 click() 

clicks on the specified element (this should help to download the file)
