How to save a webpage locally including pictures,etc
firefox, firefox-addon, html, javascript, xpcom
Solution
Since you mention that File->"Save Page As" is working as expected, I tried looking through the source code (chrome://browser/content/browser.xul) and found this:
https://developer.mozilla.org/en/nsIWebBrowserPersist#saveDocument()
Make sure that you shall call this function only after the webpage is completely loaded (not DOMContentLoaded)!!
Problem
I am building an add-on for an application. The clients are paying to view some webpages and download some files out of it. They want to automate this downloading process by add-on. So instead of selecting "Save Page as" and waiting for the download's completion, they can click the add-on and forget the process. The problem is, the webpage is providing some cookies to the browser. So the best way is File-> "Save Page As" . I want to do it through the add-on. Is there any firefox-javascript way for this?. I used nsiDownloader. But it saves only html, not the pictures,etc. Can anybody guide me in this issue? EDIT: Hi, This is the code which did the trick, thanks to sai prasad ``` var dir =Components.classes["@mozilla.org/file/local;1"] .createInstance(Components.interfaces.nsILocalFile); dir.initWithPath("C:\\filename"); var file = Components.classes["@mozilla.org/file/local;1"] .createInstance(Components.interfaces.nsILocalFile); file.initWithPath("C:\\filename.html"); var wbp = Components.classes['@mozilla.org/embedding/browser/nsWebBrowserPersist;1'] .createInstance(Components.interfaces.nsIWebBrowserPersist); alert("going to save"); wbp.saveDocument(content.document, file,dir, null, null, null); alert("saved"); ``` EDIT: But, still some webpages are not saved exactly as "Save Page as". Those saved pages are not rendered like original pages, they are look like some html example.
