I'm need a way to save the current page (including, images, CSS, etc.) from an add-on.
Of course I found the saveDocument() function in the SDK but I was not able to make it work.
from add-on script, I do not have access to actual DOM content
from content script, I do not have access to SDK function 'saveDocument()'
I miss something, I would be very happy if someone could help me.
Best regards,
Fred
here's one way to access the DOM document from addon script.
var winutil = require('sdk/window/utils');
function findDocument(predicate){
// searching in focused window only
// you can also get all windows with winutil.windows('navigator:browser')
var win = winutil.getMostRecentBrowserWindow();
var gBrowser = win.gBrowser;
// traverse tabs of focused window
for (var i=0, l=gBrowser.browsers.length; i<l; i++)
{
var br = gBrowser.getBrowserAtIndex(i);
var doc = br.contentDocument;
if (predicate(doc))
return doc;
}
}
// and this is probably how you would save (not tested)
var {Cc, Ci} = require('chrome');
var wbp = Cc["#mozilla.org/embedding/browser/nsWebBrowserPersist;1"]
.createInstance(Ci.nsIWebBrowserPersist);
var doc = findDocument(/* whatever */);
if (doc)
wbp.saveDocument(doc, /* figure out other args */);

I can't understand and solve your problem all, since your problem seems a bit too complex.
However, I know how to save a sheet as a PDF easier and get the PDF's URL automatically.
It needs a script program.
I made a sample program based on another answer.
This is my code.
function exportPDF(){
// get parameters
var sheet = SpreadsheetApp.getActiveSheet();
var sheetName = sheet.getRange("B2").getValue();
var fileName = sheet.getRange("B3").getValue();
sheet.getRange("B4").setValue("");
// export the sheet
var fileUrl = exportSheet(sheetName, fileName);
// show the url
sheet.getRange("B4").setValue(fileUrl);
}
// based on https://stackoverflow.com/questions/38335143/export-single-sheet-to-pdf-in-apps-script
function exportSheet(sheetName, fileName) {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheets = ss.getSheets();
var fileUrl = "";
try{
for (var i = 0; i < sheets.length; i++) {
if (sheets[i].getSheetName() !== sheetName) {
sheets[i].hideSheet()
}
}
var file = DriveApp.createFile(ss.getBlob());
file.setName(fileName);
file.setSharing(DriveApp.Access.ANYONE, DriveApp.Permission.VIEW);
fileUrl = file.getUrl();
}
catch(e){
console.log(e);
throw e;
}
finally{
for (var i = 0; i < sheets.length; i++) {
sheets[i].showSheet()
}
}
return fileUrl;
}
If this can help, check this sample sheet and make a copy. ([File]-[Make a copy])

I want to get speaker notes from Google Slides by API, but I could not find any fields for speaker notes.
For reference: Method: presentations.pages.get
What would be a good way to do this?
Support for speaker notes is now available in the Slides API v1. Documentation is here: https://developers.google.com/slides/how-tos/notes
In the absence of the API, I wouldn't suggest this is a good way of doing it. In fact it is horrible. But here it is. If you absolutely had to do it. It is likely a bit flakey too.
Steps are:
Export the presentation, via the Drive API, as a PowerPoint .pptx file
Unpack the file - it is a zip file containing a directory structure with XML files in.
Identify the speaker notes files and process them as per your requirement (e.g. extract all text, or work on the XML etc).
Ugly right? Here's an example in Apps Script:
Enable Drive API in Advanced Services within your script (Resources > Advanced Google Services).
function example() {
// Print out the speaker notes
Logger.log(getNotes('123abc......asd'));
}
// Returns an array of strings, one string per slide
// representing the speaker notes.
function getNotes(presentationId) {
//DriveApp.createFile();
var notesRegex = /ppt\/notesSlides\/notesSlide\d+\.xml/;
var url = 'https://www.googleapis.com/drive/v2/files/' + presentationId +
'/export?mimeType=application%2Fvnd.openxmlformats-officedocument.presentationml.presentation';
var options = {
headers: {
Authorization : 'Bearer ' + ScriptApp.getOAuthToken()
}
};
var response = UrlFetchApp.fetch(url, options);
var zipBlob = Utilities.newBlob(response.getContent(), 'application/zip');
var data = Utilities.unzip(zipBlob);
var notes = [];
for (var i = 0; i < data.length; i++) {
if (notesRegex.test(data[i].getName())) {
// Example simply extracts text from speaker notes
// You could do something more complex.
notes.push(extractTextFromXml(data[i].getDataAsString()));
}
}
return notes;
}
function extractTextFromXml(xml) {
var doc = XmlService.parse(xml);
var root = doc.getRootElement();
var ns = root.getNamespace('a');
var text = [];
function walkNode(node) {
if (node.getText()) {
text.push(node.getText());
}
var children = node.getChildren();
if (children.length) {
children.forEach(function(child) {
walkNode(child);
});
}
}
walkNode(root);
return text.join('\n');
}
I'm trying to code on google app and I've encountered one issue. For example, let's consider this example code on google website ( link's here https://developers.google.com/apps-script/class_formpanel )
function doGet() {
var app = UiApp.createApplication();
var form = app.createFormPanel();
var flow = app.createFlowPanel();
flow.add(app.createTextBox().setName("textBox"));
flow.add(app.createListBox().setName("listBox").addItem("option 1").addItem("option 2"));
flow.add(app.createSubmitButton("Submit"));
form.add(flow);
app.add(form);
return app;
}
function doPost(eventInfo) {
var app = UiApp.getActiveApplication();
app.add(app.createLabel("Form submitted. The text box's value was '" +
eventInfo.parameter.textBox +
"' and the list box's value was '" +
eventInfo.parameter.listBox + "'"));
return app;
}
My issue is that I want to select multiple values on the listbox. I change then line 6 in
flow.add(app.createListBox(true).setName("listBox").addItem("option 1").addItem("option 2"));
to allow multiple selection. But the result is that only the last selected value is taken, preventing multiple selections. Apparently, it is due to the submitButton. I need to keep the formPanel because on a further code I'll like to combine uploading files and listBox multiple selection. How may I fix that? Thank you a lot
As a complement to Mogsdad's answer, note that this bug / issue is only concerning the doPost structured handler... if you don't need the file upload feature you could use a simple doGet + handler with callbackElement and in this case the multiselect list is available and works as expected.
test function :
function doGet() {
var app = UiApp.createApplication().setTitle('test listBox');
var panel = app.createHorizontalPanel().setStyleAttribute('padding','40px');
var sHdlr = app.createServerHandler('validateList').addCallbackElement(panel);
var items = ['category 1','category 2','category 3'];
var list1 = app.createListBox(true).setName('list1');
for(var i =0;i<items.length;++i){list1.addItem(items[i],i)}
panel.add(list1).add(app.createButton('validate',sHdlr));
app.add(panel);
return app;
}
function validateList(e){
var app = UiApp.getActiveApplication();
app.add(app.createLabel("Value(s) in list : "+e.parameter.list1).setStyleAttribute('margin-left','40'));
return app;
}
and below is a working example of the workaround described in the issue tracker.
I used a textBox to show the process, set it to visible(false) or use a hidden widget in a 'real' app. ( Test available here )
function doGet() {
var app = UiApp.createApplication().setTitle('test listBox');
var panel = app.createHorizontalPanel().setStyleAttribute('padding','40px');
var listHandler = app.createServerHandler('updlistVal').addCallbackElement(panel);
var items = ['category 1','category 2','category 3'];
var list1 = app.createListBox(true).setName('list1').addChangeHandler(listHandler);
for(var i =0;i<items.length;++i){list1.addItem(items[i])}
panel.add(list1).add(app.createTextBox().setText(items[0]).setId('listboxVal').setName('listboxVal').setWidth('200'));// set a default value in case the user is happy with that and doesn't touch the listBox
var submitBtn = app.createSubmitButton('test').setStyleAttribute('margin-left','40');
app.add(app.createFormPanel().add(panel.add(submitBtn)));
return app;
}
function doPost(e){
var app = UiApp.getActiveApplication();
app.add(app.createLabel().setStyleAttribute('padding','40').setText("Submitted value(s) from list : "+e.parameter.listboxVal));
return app;
}
function updlistVal(e){
var app = UiApp.getActiveApplication();
app.getElementById('listboxVal').setValue(e.parameter.list1);
return app;
}
EDIT 2 :
As Mentioned in the comments on this post we must find a way to prevent going through the submission before the value of the hidden/text widget has been updated with a valid value. The "default value" I used above is a possible solution, another one is to use a client handler to validate the submit button only if the listValue (or its value in the hidden widget) is right. Here is a code that does it (only the doGet is reproduced, all other functions being identical.
function doGet() {
var app = UiApp.createApplication().setTitle('test listBox');
var panel = app.createHorizontalPanel().setStyleAttribute('padding','40px');
var submitBtn = app.createSubmitButton('test').setStyleAttribute('margin-left','40').setEnabled(false);
var listHandler = app.createServerHandler('updlistVal').addCallbackElement(panel);
var items = ['category 1','category 2','category 3'];
var listVal = app.createTextBox().setText('not defined yet').setId('listboxVal').setName('listboxVal').setWidth('200');
var list1 = app.createListBox(true).setName('list1').addChangeHandler(listHandler).addItem('choose one or more item(s)');
for(var i =0;i<items.length;++i){list1.addItem(items[i])}
var clientH = app.createClientHandler().forTargets(submitBtn).setEnabled(true).validateMatches(list1, 'category');
list1.addClickHandler(clientH);
panel.add(list1).add(listVal);// set a default value in case the user is happy with that and doesn't touch the listBox
app.add(app.createFormPanel().add(panel.add(submitBtn)));
return app;
}
Using the hidden widget as validation source causes a small issue as we need to click twice on the listBox to make it work... in case there are other questions on the form this will be solved by triggering the client handler with every other widgets so that the double click won't be necessary anymore but this is becoming a bit "out of subject" I'm afraid.
EDIT 3 :
just for the fun of it, a last version that works apparently without issue...
test here
function doGet() {
var app = UiApp.createApplication().setTitle('test listBox');
var panel = app.createHorizontalPanel().setStyleAttribute('padding','40px');
var submitBtn = app.createSubmitButton('test').setStyleAttribute('margin-left','40').setEnabled(false).setId('sbmt');
var wait = app.createImage('https://dl.dropboxusercontent.com/u/211279/loading3T.gif').setId('wait').setVisible(false);
var listHandler = app.createServerHandler('updlistVal').addCallbackElement(panel);
var items = ['category 1','category 2','category 3'];
var listVal = app.createTextBox().setText('not defined yet').setId('listboxVal').setName('listboxVal').setWidth('200');
var list1 = app.createListBox(true).setName('list1').addChangeHandler(listHandler).addItem('choose one or more item(s)');
for(var i =0;i<items.length;++i){list1.addItem(items[i])}
var clientH = app.createClientHandler().forTargets(wait).setVisible(true).forTargets(submitBtn).setEnabled(false);
list1.addChangeHandler(clientH);
panel.add(list1).add(listVal);// set a default value in case the user is happy with that and doesn't touch the listBox
app.add(app.createFormPanel().add(panel.add(submitBtn).add(wait)));
return app;
}
function doPost(e){
var app = UiApp.getActiveApplication();
app.add(app.createLabel().setStyleAttribute('padding','40').setText("Submitted value(s) from list : "+e.parameter.listboxVal));
return app;
}
function updlistVal(e){
var app = UiApp.getActiveApplication();
app.getElementById('listboxVal').setValue(e.parameter.list1);
app.getElementById('sbmt').setEnabled(true);
app.getElementById('wait').setVisible(false);
return app;
}
This is a known bug in the issue tracker, Issue 959. Visit and star it for updates.
It's been known and "worked on" since Dec 2011, if you believe the notes added by the support team. Other users have provided a work-around, and a modified version of it appears below.
The idea is to attach a handler function to the ListBox, which will receive all the selected items from the ListBox. The handler will then write those values to a hidden element in the form. When the form is submitted, the list of selections will be available to the doPost(), via the hidden element.
...
var listbox = app.createListBox(true).setName("listBox").addItem("option 1").addItem("option 2");
flow.add(listbox);
// Issue 959 ListBox Workaround: http://code.google.com/p/google-apps-script-issues/issues/detail?id=959
var listboxHidden= app.createHidden("listboxHidden", "").setId("listboxHidden");
flow.add(listboxHidden);
var fixListBoxHandler = app.createServerHandler('fixListBoxHandler');
fixListBoxHandler.addCallbackElement(listbox);
listbox.addChangeHandler(fixListBoxHandler);
...
}
function fixListBoxHandler(e) {
var app = UiApp.getActiveApplication();
app.getElementById('listboxHidden').setValue(e.parameter.listbox);
return app;
}
NOTE: Unfortunately, this work-around is time-sensitive; it can take several seconds for the handler to update the hidden value. If the submit button is hit before the handler completes its job, then post() receives what was in the hidden element before the call to the handler.
When user click on the button in toolbar of Firefox I need to change content
of the current active html page. In standart]d implementation it's look like this :
function injectNewContent() {
var pageHtml =
[
"<html>",
"<head>",
"</head>",
"<frameset cols='270,*' frameborder='0'>",
"<frame name='frameI' src='http://www.123.com/default.html'>",
"<frame name='frameII' src='" + document.location + "'>",
"<noframes>",
"<body>",
"noframes",
"</body>",
"</noframes>",
"</frameset>",
"</html>"
];
var fullPageHtml = "";
for (var i in pageHtml)
{
fullPageHtml += pageHtml[i];
}
window.document.write(fullPageHtml);
}
What I need to change in this code to get same functionality ?
var windowMediator = Components.classes['#mozilla.org/appshell/window-mediator;1'].
getService(Components.interfaces.nsIWindowMediator);
var recentWindow = windowMediator.getMostRecentWindow("navigator:browser");
recentWindow. ???
Or may be I do something wrong ?
Thanks for any help...
You don't need to go looking for the browser window, your button is already sitting on one. To access the content area of the current tab simply use window.content. This should do what you want:
var doc = window.content.document;
doc.open("text/html", true);
doc.write(fullPageHtml);
doc.close();
Though personally I would rather assign HTML code to doc.documentElement.innerHTML.
I need to get the cache file path for ever image loaded in a document, I am wondering what are the Interfaces I need to use in order to do that
https://developer.mozilla.org/en/XPCOM_Interface_Reference
This is what I used to evict cache entry:
function removeItem(url){
let cacheService = Components.classes["#mozilla.org/network/cache-service;1"]
.getService(Components.interfaces.nsICacheService);
var Ci = Components.interfaces;
var session = cacheService.createSession("image", Ci.nsICache.STORE_ANYWHERE, false);
if(!session){
return;
}
var entry;
try{
entry = session.openCacheEntry(url, Ci.nsICache.ACCESS_READ, false);
if(!entry){
return;
}
}catch(ex){
return;
}
entry.doom();
entry.close();
}
}
Once you have entry you should be able to open a stream to it - possibly getting the content or even replacing it - I haven't tried it though.
