Question

So, I have a string with the delimiter | , one of the sections contains “123”, is there a way to find this section and print the contents?
something like PHP explode (but Javascript) and then a loop to find ‘123’ maybe? :/

Answer 1

const string = "123|34|23|2342|234";
const arr = string.split('|');

for(let i in arr){
    if(arr[i] == 123) alert(arr[i]);
}

Or:

for(let i in arr){
    if(arr[i].indexOf('123') > -1) alert(arr[i]);
}

Or:

arr.forEach((el, i, arr) => if(arr[i].indexOf('123') > -1) alert(arr[i]) }

Or:

arr.forEach((el, i, arr) => if(el == '123') alert(arr[i]) }

Or:

const arr = "123|34|23|2342|234".split('|')

if(arr.some(el=>el == "123")) alert('123')
