4-
My fork + changes of/to https://github.com/nwcell/ics.js
4+
My fork of the original ics.js
5+
6+
I took out the FileSaver.js and Blob.js parts as it better fit my needs.
7+
Please have a look at the original repository!! -- https://github.com/nwcell/ics.js
8+
(At least thats where I got my fork)
9+
10+
PLEASE NOTE: I only tested this simplification with single events and on Chrome/Firefox !!
11+
12+
13+
My changes where applied to the download() function - have a look yourself :-)
14+
15+
My suggested use is to have a onclick or controller/service function (in case you use Angular or stuff) that builds your nice calendar data:
16+
17+
Example:
18+
---------
19+
var buildICSEntry = function( javascriptExampleDateObject ){
20+
21+
var calEntry = icsFormatter();
22+
23+
var title = 'sometitlestring';
24+
var place = 'our secret meeting place';
25+
var begin = new Date(javascriptExampleDateObject);
26+
var end = new Date(Beginn.getTime() + 30*60000);
27+
28+
var description = 'A very long and boring description of what is the agenda of this super exclusiv pow-wow';
29+
30+
calEntry.addEvent(title,description, place, begin.toUTCString(), begin.toUTCString());
31+
calEntry.download('ourSecretMeeting');
32+
}
33+
34+
35+
/* Original Readme End */
36+
37+
