I am new to jqeury. 

Could you please tell me how to get the most of this script. I wrote it by myself and there is quite few repetitions. 

2.             $("textarea[name='storyline']").blur(function() {
3.                 storylineAjaxUpdate();
4.                 eventViewer('Storyline has been saved');
5.             });
6. 
   
7.             var strokeCount = 0;
8.             $("textarea[name='storyline']").keyup(function() {
9.                 strokeCount = ++strokeCount;
10. 
    
11.                 if (strokeCount > 100) {
12.                     storylineAjaxUpdate();
13.                     eventViewer('Storyline has been saved');
14.                     strokeCount = 0;
15.                 }
16.             });
17. 
    
18.             function eventViewer(msg) {
19.                 var date = new Date();
20. 
    
21.                 var minutes = date.getMinutes();
22.                 var hours = date.getHours();
23.                 var seconds = date.getSeconds();
24. 
    
25.                 $(".eventManager .menu-title").after("<p>" + msg + "<span class='small'> (" + hours + ":" + minutes + ":" + seconds + ")</span></p>");
26.                 $(".eventManager p:eq(1)").fadeOut(6000);
27.             }
28. 
    
29.             function storylineAjaxUpdate(success = '', error = '') {
30.                 var storyline = $("textarea[name='storyline']").val();
31.                 var token = $("input[name='_token']").val();
32. 
    
33.                 $.ajax({
34.                     type: 'PATCH',
35.                     url: "{{ url('/') }}/admin/dealer/add-article/storyline/{{ $articleToEdit->id }}",
36.                     dataType: 'json',
37.                     data: {
38.                         'storyline': storyline,
39.                         '_token': token
40.                     },
41.                     success: success,
42.                     error: error,
43.                 });
44. 
    

so that is the code. I want to create autosave for my articles and storyline. This script taking care of just the storyline. 

as I am new to jquery I would like to know what I can actually improve before writing the article part. 

I would also point at the coloured parts. 

RED , I dont like that the variable is out of the block. Can I move it in any way? 

BLUE , I consider this a little bit crazy. Is there any better way how to work with date and time? Couldnt find anything easier. 

How can I add 0 before digits of one place e.g. 1, 2, 3...?

Thank you.
