How do I extract the text from the beginning until (not including) the second to last occurrence of a charachter (":" in this case) from a string? Preferably without using regex.
Examples:
"urn:riv:intygsbestallning:certificate:order:RequestPerformerForAssessmentResponder:1" should become "RequestPerformerForAssessmentResponder:1"
"urn:riv:itinfra:tp:PingResponder:1" should become "PingResponder:1"
with split function you can parse your string returning an array of the tokens separated from the string in the parameter of split and later you can concatenate last two items in the array
let x = "urn:riv:intygsbestallning:certificate:order:RequestPerformerForAssessmentResponder:1";
let result = x.split(":");
let yourTextResult = `${result[result.length-2]}:${result[result.length-1]}`;
console.log(yourTextResult );const data1 = "urn:riv:intygsbestallning:certificate:order:RequestPerformerForAssessmentResponder:1";
const data2 = "urn:riv:itinfra:tp:PingResponder:1"
const arr = data1.split(':');
console.log(arr.splice(arr.length-2,arr.length).join(':'))str = 'urn:riv:intygsbestallning:certificate:order:RequestPerformerForAssessmentResponder:1'
split_array = str.split(':')
ans = split_array.splice(-2).join(':')
console.log('ans', ans)
cut_off_part = split_array.join(':') + ':'
console.log('cut_off part', cut_off_part)
Another way of doing the same:
str = 'urn:riv:intygsbestallning:certificate:order:RequestPerformerForAssessmentResponder:1'
ans = str.split(':').splice(-2).join(':')
console.log("answer", ans)
cutoff_part = str.substr(0, str.length - ans.length)
console.log("cut_off_part", cutoff_part)
