23,610,681 | 0 | <p>Here is one solution I propose which may not be the solution you may want but here it is. Since it's a table and everything comes one after other, what you can do is, through appropriate Jsoup selectors get the following data one after another.</p> <pre><code>Mo Do Mi Do Fr Sa 8:00 9:30 9:45 11:45 Sem Wz J0122 11:30 13:30 CAE Wz J0122 1) SEM Wz J0122 DVI Eer J0326 2) </code></pre> <p>...and so on...</p> <p>Now since you know there are only six working days in a week. You can create a HashMap of String and a LinkedList. String for days of the week and LinkedList for the content which goes in it. In the LinkedList you can first put time and check whether that time has any course following it, then repeat that for all the other timings.</p> <p>So you now have the data structure that all you need to do is call the day of the week (and the timing if necessary) and get the required course.</p> |

The reason why a <code>change</code> event is triggered is for two reasons</p> <ul> <li>Older versions of Select2 used to trigger the <code>change</code> event, so we gave an easy-upgrade path.</li> <li>Other components on the page should be listening to the <code>change</code> event to know when the value of the <code><select></code> changes, so it makes sense to trigger it.</li> </ul> <p>Second, Select2 can only know if the underlying value of the <code><select></code> changes if you trigger the <code>change</code> event.</p> <p>So when you combine these two issues together, it starts to explain why Select2 doesn't act as you would expect when you set the new value within a <code>change</code> event.</p> <hr> <p>You can get around the cyclic <code>change</code> events by using the <code>select2:select</code> event to determine when a new selection is made, instead of the <code>change</code> event.</p> <p><a href="https://jsfiddle.net/nmeoosLk/8/" rel="nofollow">https://jsfiddle.net/nmeoosLk/8/</a></p> <p>This is locking you into using Select2-specific events, but it's your best alternative if you don't want to always check if the value changed. I personally would recommend not triggering the <code>change</code> event if the value didn't change, as the small amount of code will better help other components understand what is happening on the page.</p> |

39,704,721 | 0 | <p>Rather than attempting parse every line from the url and put it into specific rows for a csv file, you can just push it all into a text file to clean up the formating, and then read back from it, it may seem like a bit more works but this is generally my approach to comma delimited information from a URL. </p> <pre><code>import requests URL = "http://www.cftc.gov/dea/newcot/FinFutWk.txt" r = requests.get(URL,stream=True) with open('file.txt','w') as W: W.write(r.text) with open('file.txt', 'r') as f: lines = f.readlines() for line in lines: print(line.split(',')) </code></pre> <p>You can take what is in that forloop, and swap it around to actually saving the lists into a array of lists so you can use rather than print them.</p> <pre><code>content = [] for line in lines: content.append(line.split(',')) </code></pre> <p>Also note that upon splitting, you will still notice that there is content that has quite a large amount of white space after it, you could run through the entire list, for each list in the array, and remove all white space but that would ruin the first element in the list, or just convert the numeric values which have the white space into actual integers as they were read in as strings. That would be your preference. If you have any questions feel free to add a comment below.</p> <p>EDIT 1: On a side note, if you do not wish to keep the file that was saved with the content, import the os library and then after you read the lines into the lines array, remove the file.</p> <pre><code>import os os.remove('file.txt') </code></pre> |

I haven't messed with removing whitespace yet and am currently focusing on building the file reader portion. </p> <p>Fixed: My current issue is that this code returns data from the third row for $StartPosition and from the fourth row for $Length when they should both be first found on the first row of COMMA. I have no idea what is prompting this behavior.</p> <p>Next issue: It only reads the first record in practice_data.txt I'm guessing it's something where I need to tell COMMA to go back to the beginning?</p> <pre><code>while (my $sourceLine = <SOURCE>) { $StartPosition = 0; $Length = 0; $Output = ""; $NextRecord =""; while (my $commaLine = <COMMA>) { my $Comma = index($commaLine, ','); print "Comma location found at $Comma \n"; $StartPosition = substr($commaLine, 0, $Comma); print "Start position is $StartPosition \n"; $Comma = $Comma + 1 $Length = substr($commaLine, $Comma); print "Length is $Length \n"; $NextRecord = substr($sourceLine, $StartPosition, $Length); $Output = "$Output . ',' . $NextRecord"; } print OUTPUT "$Output \n"; } </code></pre> <p><strong>practice_data.txt</strong></p> <pre><code>1234512345John Doe 123 Mulberry Lane Columbus Ohio 43215Johnny Jane 5432154321Jason McKinny 423 Thursday Lane Columbus Ohio 43212Jase Jamie 4321543212Mike Jameson 289 Front Street Cleveland Ohio 43623James Sarah </code></pre> <p>Each record is 100 characters long. <strong>Definitions.txt:</strong></p> <pre><code>0,10 10,10 20,10 30,20 50,10 60,10 70,5 75,15 90,10 </code></pre> |
