read csv-data and put it in an array

Perlchamp

@sdetweil said in read csv-data and put it in an array:

the names of the object elements are the names of the columns (row 1 in the csv)

yes i know.
i thought it’s an dictionairy and not an array. but it’s ok …

@Perlchamp the [ (open square bracket) means array in javascript

the array can be numbers, strings or objects (open squiggly bracket)

status:
i wanted to “play” with the jsonArray, but things like jsonArray[“birth”][0] or jsonArray.birth[3] will not be accepted, although it is listed in many websites … i try and try and read and read, but in the moment no solution. the parameter “length” count the number of letters and numbers ?
then I will have to deal with moment () first …

@Perlchamp u did not show the code, so I will call the output of the csvtojson() birthday_info

example of how to navigate the json data

in module there would be no ‘var’ cause of the way the modulename and helper are packaged inside object

// if not using numbers but month names 
// make indexOf return 1-12, not 0-11 (dummy thing never matched 1st)
// fix this with your language abbreviations
// usually in lower case, then always convert data to lowercase for compare to prevent having users remember to get the case right
var months= ["0", "jan","feb","mar"...."dec"]

var today_day_month = moment().format("DDMM")
// today would be "3004"
// tomorrow will be "0105"
// loop thru the array of birthday info from file, one 'row' per birthday

for(var birthday of birthday_info) {
     // get the day/month string in numbers to match output of moment()
     // get the last 2 chars of the day and month with a 0 on front.. 01-09, 12, ---31, or 01-09,10/11/12
     if( ("0"+birthday.Geburtstag).subString(-2)+("0"+months.indexOf(birthday.Geburtsmonat.toLowerCase())).subString(-2) 
                         == today_month_day) {
         // this birthday is for today
            condole.log(" birthday on "+ today_day _month+" is for "+birthday.Name);
     } 
}

i didn’t post the code, because it only was a status-info …
but here is the code. i think i will first try alone. if there any questions i will post them.
here is my array:

[{"birth":"12.09.1967", "name":"Otto Billing"},{...}]

many thanks in advance

@Perlchamp ok, went to numbers, SO much easier!!

var today_day_month = moment().format("DD.MM")
// today would be "30.04"
// tomorrow will be "01.05"
// loop thru the array of birthday info from file, one 'row' per birthday

for(var birthday of birthday_info) {
     if( (birthday.birth.startsWith(today_day_month)) {
         // this birthday is for today
            console.log(" birthday on "+ today_day_month+" is for "+birthday.name);
     } 
}

ok, i will try. therefor my array don’t match, i think … that’s right ?

@Perlchamp the new data matches my new code

Perlchamp

thanks, but now i’m a little bit confused, because my master problem will be, to reorg the array, to combine people with the same date of birth in as list in one row with the day of birth. but let me try …

@Perlchamp ok, this was just to give you ideas on how to access the data… in a useful way
