create .ics file on the fly using javascript or jquery? - javascript

Can someone tell me if there is any jquery plugin to dynamically create .ics file with values coming from the page div values like there would be
<div class="start-time">9:30am</div>
<div class="end-time">10:30am</div>
<div class="Location">California</div>
or javascript way to dynamically create an .ics file? I basically need to create .ics file and pull these values using javascript or jquery? and link that created ics file to "ADD TO CALENDAR" link so it gets added to outlook?

you will need to make it in ICS format. also you will need to convert the date and time zone; E.G. 20120315T170000Z or yyyymmddThhmmssZ
msgData1 = $('.start-time').text();
msgData2 = $('.end-time').text();
msgData3 = $('.Location').text();
var icsMSG = "BEGIN:VCALENDAR\nVERSION:2.0\nPRODID:-//Our Company//NONSGML v1.0//EN\nBEGIN:VEVENT\nUID:me#google.com\nDTSTAMP:20120315T170000Z\nATTENDEE;CN=My Self ;RSVP=TRUE:MAILTO:me#gmail.com\nORGANIZER;CN=Me:MAILTO::me#gmail.com\nDTSTART:" + msgData1 +"\nDTEND:" + msgData2 +"\nLOCATION:" + msgData3 + "\nSUMMARY:Our Meeting Office\nEND:VEVENT\nEND:VCALENDAR";
$('.test').click(function(){
window.open( "data:text/calendar;charset=utf8," + escape(icsMSG));
});
the above sample will create a ics file for download. the user will have to open it and outlock, iCal, or google calendar will do the rest.

This is an old question, but I have some ideas that could get you started (or anyone else who needs to do a similar task).
And the JavaScript to create the file content, and open the file:
var filedata = $('.start-time, .end-time, .Location').text();
window.open( "data:text/calendar;charset=utf8," + escape( filedata ) );
Presumably you'd want to add that code to the onclick event of a form button.
I don't have Outlook handy, so I'm not sure if it will automatically recognize the filetype, but it might.
Hope this helps.

From what I have found online and on this site, it is not possible to get this to work in IE as you need to include certain headers to let IE know to download this file.
The window.open method works for Chrome and Firefox but not IE so you may need to restructure your code to use a server-side language to generate and download the ICS file.
More can be found in this question

While this is an older question, I have been looking for a front-end solution as well. I recently stumbled across the
ICS.js library which looks like the answer you're looking for.

This approach worked fine however with IE8 the browser couldn't recognize the file type and refused to open as a calendar item. To get around this i had to create the code on the server side (and exposed via RESTful service) and then set the response headers as follows;
#GET
#Path("generateCalendar/{alias}/{start}/{end}")
#Produces({ "text/v-calendar" })
public Response generateCalendar(
#QueryParam("alias") final String argAlias,
#QueryParam("start") final String argStart,
#QueryParam("end") final String argEnd) {
ResponseBuilder builder = Response.ok();
builder.header("content-disposition", "attachment;filename=calendar.ics");
builder.entity("BEGIN:VCALENDAR\n<........insert meeting details here......>:VCALENDAR");
return builder.build();
}
This can be served up by calling window.location on the service URL and works on Chrome, Firefox and IE8.
Hope this helps.

export "saved for later" from (evil) feedly

i'm trying to migrate from feedly as it is unacceptable (at least to me) that a search query is (fully) enabled only by a pro version.
Anyhow, to export my lengthy list of "saved for later" i found some lovely scripts:
Simple script that exports a users "Saved For Later" list out of Feedly as a JSON string and feedly-to-pocket. where i am instructed to:
You must switch off SSL (http rather than https) or jQuery won't load!
so i though i did by adding (ubuntu 14.04/chrome 40 x64)
--ssl-version-min=tls1
to my /usr/share/applications/google-chrome.desktop file (all lines starting with Exec=). However when i try to run it in the browser console i get
This request has been blocked; the content must be served over HTTPS.
So, any suggestions? (also, excuse me for noobness)
Go to your Feedly "saved" list and scroll down until all articles have loaded.
Open console and paste the following Javascript into it:
function loadJQuery() {
script = document.createElement('script');
script.setAttribute('src', '//code.jquery.com/jquery-2.1.3.js');
script.setAttribute('type', 'text/javascript');
script.onload = loadSaveAs;
document.getElementsByTagName('head')[0].appendChild(script);
}
function loadSaveAs() {
saveAsScript = document.createElement('script');
saveAsScript.setAttribute('src', 'https://cdn.rawgit.com/eligrey/FileSaver.js/5733e40e5af936eb3f48554cf6a8a7075d71d18a/FileSaver.js');
saveAsScript.setAttribute('type', 'text/javascript');
saveAsScript.onload = saveToFile;
document.getElementsByTagName('head')[0].appendChild(saveAsScript);
}
function saveToFile() {
// Loop through the DOM, grabbing the information from each bookmark
map = jQuery(".entry.quicklisted").map(function(i, el) {
var $el = jQuery(el);
var regex = /Published:(.*)(.*)/i;
return {
title: $el.attr("data-title"),
url: $el.attr("data-alternate-link"),
summary: $el.find(".summary")[0].innerHTML,
time: regex.exec($el.find("span.ago").attr("title"))[1]
};
}).get(); // Convert jQuery object into an array
// Convert to a nicely indented JSON string
json = JSON.stringify(map, undefined, 2);
var blob = new Blob([json], {type: "text/plain;charset=utf-8"});
saveAs(blob, "FeedlySavedForLater" + Date.now().toString() + ".txt");
}
loadJQuery()

Not javascript but here is how I saved a html page with all the links and excerpts...
Open the saved pages in feedly in chrome
scroll down so they are all there
inspect any element (the top article is a good choice) so it opens the generated html
find the div id="section0_column0" node
right-click & copy it
paste into Notepad++
this html is untidy so carry on...
Do a Regex find & replace
find: (?s)<div id=.+?_main.+?>.+?(<a href=")(.+?)(").+?sans-serif">(.+?)</span>.+?</div>.+?</div>.+?</div>
replace: <div>$1$2$3>$2</a></div> <div> $4<br /> <br /></div>
save the html page.
open it in Chrome
Posted the question in the jquery forum and the solution was rather simple (remove http from attribute string)
line 34 should be
script.setAttribute('src', '//code.jquery.com/jquery-latest.min.js');
So to close the loop - for a full searchable/archived list of links not only by title/url but context also(!) you can:
Follow the instructions in https://github.com/ShockwaveNN/feedly-to-pocket (with the correction suggested by kind stranger jakecigar and you also have to register a pocket app (obtain consumer key) for the ruby script to work)
Export html list from your pocket account
Import pocket list to a Kifi library
and at last feedly-free with my personal search engine
I know I'm a bit late to the party but Ive been hunting around for a few days to find a reasonably simple solution. None of which have been listed clearly or concisely on stack overflow or elsewhere on the web. I have in fact found a much easier way to do this.
Use this java script from this Gist just as it instructs https://gist.github.com/ShockwaveNN/a0baf2ca26d1711f10e2 (Note this is referenced above and found through the link #gep shared in step one)
Once the JS as completed running it will download a text file. (It does still run successfully and on large numbers, I just exported almost 2500 articles)
Create a blank test.json in SublimeText.
Copy all entries from your exported text file into this json file
Weirdly it does seem you need to copy and past as I tried just renaming the text file and when I did that I received errors on the next step
Make sure you are signed into pocket
Go here: https://getpocket.com/import/springpad
Select your newly created test.json
Upload
Note: On large uploads the import page fails to refresh (this did not seem to be an issue as all my articles did make it into my account)
This allows you to directly upload json into your pocket account. Thus no more messing around with random supposed other fixes. I hope this make it a lot easier for everyone in the future.

Get Element available under Dev Tools -> Resources -> Frames

I'm trying to do this by using a Tampermonkey Script. However I'm open to new approaches...
What I want to do is extract some data (data-video), from a specific <div>. However this data is not available under the HTML code of the page, but it's available under Dev Tools -> Resources and then on Frames.
Anyone knows if it's possible to get that information available under DevTools? And how can I do that?
Comparative between the two pages can be found here: "Original HTML PAGE" and "HTML PAGE under DevTools"
On the first hyperlink the id=video-canvas cannot be seen, however it's on the <object type="application/x-shockwave-flash(...)
As you state in your question the data you're looking for is available in DevTools under the "Resources" tab in the "Frames" folder. What you are looking at there is the Source HTML, similar to View Source.
The code you want, is what is getting replaced. It appears the site is using the JW Player Plugin, which is replacing the <div id="video-canvas"> with the appropriate HTML for the device / browser detected to play the video. With all of my browsers on my Mac, they are being forced to use the Flash, even when it's disabled. When using my iPhone, which can't play flash , and inspecting the page it uses JW's own custom video element. It appears that it must be storing the file location in memory since it is not in the generated markup.
I am able to run through the console in the dev tools and access their JS class. It appears i can call jwplayer._tracker , which has an object b . Object b has an object AlWv3iHmEeOzwBIxOUCPzg This object seems to be consistent each time i check between different browsers, you can use the for loop inmy first example to get the correct value but tirmming it down to .b Following that object is e and in e is the object http://i.n.jwpltx.com/v1.... really long string that appears to contain a url, so it will need to parsed.
So to get the HTML string i ran
for ( var loc in jwplayer._tracker.b.AlWv3iHmEeOzwBIxOUCPzg.e){
loc
}
so if we put that in a function to parse the string and return a value
function getSubURL(){
var initURL;
for ( var loc in jwplayer._tracker.b.AlWv3iHmEeOzwBIxOUCPzg.e){
initURL = loc;
}
//look for 'mp4:' this is in front of the file path
var start = initURL.indexOf("mp4%3A");
//look for the .mp4 for the end of the file name
var stop = initURL.indexOf(".mp4");
//grab the string between
//start+6 to remove characters used to find it
//and stop+4 to include characters used to find it
var subPath = (initURL.substring((start+6),(stop+4))).split("%2F").join("/");
return subPath;
}
//and run it
getSubURL();
it will return ciencia/astronomia/fimsol.mp4
you can run this from your console, but I am unaware of how you can use this in Tamper Monkey, but i think it gets ya a lot closer to what you wanted.
This is the approach I've used to solve my problem... I couldn't grab the code I want under Dev Tools, but I find a way to get the data from jwplayer with the function getPlaylistItem. And this is how I get the url filename of each video:
function getFilename(filename) {
var filename;
if(jwplayer().getPlaylistItem){
filename = jwplayer().getPlaylistItem()['file'];
}
else{
return filename;
}
filename = filename.substring(filename.indexOf("/mp4:") + 5);
return filename;
}

WP8 App misbehaving due to StreamWrite in JavaScript

I would like to save the results calculated on html page in a textfile using javascript.
<script type="text/javascript">
window.onload = function () {
var sw : StreamWriter = new StreamWriter("HTML_Results.txt");
sr.Write('xyz");
*** calculations ******
sr.Write (result);
}
</script>
by doing this, my WP8 App is misbehaving and not displaying images as usual. This app is an Image Fader (calculates FPS).
Also tried:
StreamWriter sr;
try {
sr = new StreamWriter("\HTML5\HTMLResults.txt");
sr.Write("xyz");
File.SetAttributes("HTML5\HTMLResults.txt", FileAttributes.Hidden);
} catch(IOException ex) {
console.write ("error writing"); //handling IO
}
The aim is to:
Extract calculated values of several html pages(after getting loaded
one by one) in a single text file.
A Resultant HTML that reads this
text file and displays results in a tabular format.
Is there a better way to this job or the above can be rectified and used? Appreciate help.
Perhaps I've misunderstood your code but it looks like you're trying to write Java within JavaScript scripting tags. You cannot write Java in an HTML document. As far as I know, client-side JavaScript (which given your <script> tags is I guess what you're trying to write) can't perform the kind of file I/O operations you seem to want here.
You need to use Node JS to use JavaScript for something like that and then you're talking server-side. The closest you can get on client-side is using the new localStorage feature in HTML5 (not supported by all browsers).

Set PDF page layout to "TwoPageLeft" using JavaScript (Acrobat Pro)

I would like to change (or add if it doesn't exist) to a PDF file with multiple pages the setting that will force the PDF to be opened in two page mode (PageLayout : TwoPageLeft for example).
I tried with that kind of JavaScript (given with Enfocus FullSwitch as example) :
if(($error == null) && ($doc != null))
{
try
{
$outfile = $outfolder + '/' + $filename + ".pdf";
$doc.layout = "TwoPageLeft";
$doc.saveAs( {cPath : $outfile, bCopy : true});
$outfiles.push($outfile);
}
catch(theError)
{
$error = theError;
$doc.closeDoc( {bNoSave : true} );
}
}
But it doesn't work as I would like (it will be opened with Acrobat Pro and saved as a new file without including the setting about the layout).
Does anyone can help me to correct that code to let JS open the PDF file, set the layout inside the PDF datas and save it out?
The readable information inside the PDF file should looks like this:
PageLayout/TwoPageLeft/Type/Catalog/ViewerPreferences
For information, I'm using FullSwitch (Enfocus) to handle files in a workflow, with Acrobat Pro, and at this time, it's only saving the file without adding the setting.
I can't find myself the answer over all the Web I searched recently, so I askā€¦
Thanks in advance!
I think you copied the "this.layout = ..." line out of the Acrobat JavaScript reference documentation, correct?
When you write a JavaScript for Switch to execute (or rather for Switch to instruct Acrobat to execute for you), you should use the "$doc" variable to refer to the document Switch is processing.
So try changing the line:
$this.layout = "TwoColumnLeft";
to
$doc.layout = "TwoColumnLeft";
As you say the rest of the code works and the document is saved without errors I assume the rest of your code is correct. The change proposed here will make the adjustment in the document you're looking for.

Inject local .js file into a webpage?

I'd like to inject a couple of local .js files into a webpage. I just mean client side, as in within my browser, I don't need anybody else accessing the page to be able to see it. I just need to take a .js file, and then make it so it's as if that file had been included in the page's html via a <script> tag all along.
It's okay if it takes a second after the page has loaded for the stuff in the local files to be available.
It's okay if I have to be at the computer to do this "by hand" with a console or something.
I've been trying to do this for two days, I've tried Greasemonkey, I've tried manually loading files using a JavaScript console. It amazes me that there isn't (apparently) an established way to do this, it seems like such a simple thing to want to do. I guess simple isn't the same thing as common, though.
If it helps, the reason why I want to do this is to run a chatbot on a JS-based chat client. Some of the bot's code is mixed into the pre-existing chat code -- for that, I have Fiddler intercepting requests to .../chat.js and replacing it with a local file. But I have two .js files which are "independant" of anything on the page itself. There aren't any .js files requested by the page that I can substitute them for, so I can't use Fiddler.
Since your already using a fiddler script, you can do something like this in the OnBeforeResponse(oSession: Session) function
if ( oSession.oResponse.headers.ExistsAndContains("Content-Type", "html") &&
oSession.hostname.Contains("MY.TargetSite.com") ) {
oSession.oResponse.headers.Add("DEBUG1_WE_EDITED_THIS", "HERE");
// Remove any compression or chunking
oSession.utilDecodeResponse();
var oBody = System.Text.Encoding.UTF8.GetString(oSession.responseBodyBytes);
// Find the end of the HEAD script, so you can inject script block there.
var oRegEx = oRegEx = /(<\/head>)/gi
// replace the head-close tag with new-script + head-close
oBody = oBody.replace(oRegEx, "<script type='text/javascript'>console.log('We injected it');</script></head>");
// Set the response body to the changed body string
oSession.utilSetResponseBody(oBody);
}
Working example for www.html5rocks.com :
if ( oSession.oResponse.headers.ExistsAndContains("Content-Type", "html") &&
oSession.hostname.Contains("html5rocks") ) { //goto html5rocks.com
oSession.oResponse.headers.Add("DEBUG1_WE_EDITED_THIS", "HERE");
oSession.utilDecodeResponse();
var oBody = System.Text.Encoding.UTF8.GetString(oSession.responseBodyBytes);
var oRegEx = oRegEx = /(<\/head>)/gi
oBody = oBody.replace(oRegEx, "<script type='text/javascript'>alert('We injected it')</script></head>");
oSession.utilSetResponseBody(oBody);
}
Note, you have to turn streaming off in fiddler : http://www.fiddler2.com/fiddler/help/streaming.asp and I assume you would need to decode HTTPS : http://www.fiddler2.com/fiddler/help/httpsdecryption.asp
I have been using fiddler script less and less, in favor of fiddler .Net Extensions - http://fiddler2.com/fiddler/dev/IFiddlerExtension.asp
If you are using Chrome then check out dotjs.
It will do exactly what you want!
How about just using jquery's jQuery.getScript() method?
http://api.jquery.com/jQuery.getScript/
save the normal html pages to the file system, add the js files manually by hand, and then use fiddler to intercept those calls so you get your version of the html file
