How to split a string in js

Question

I have a string like below and I want to split it and get the value before pipe (|).

var str = "110|paris";

I just want to store like below,after split

var value = 100;

Answer 1

This:

var value = str.split('|')[0];

will give you what's before the pipe. More generally:

var array = str.split('|');

this will give you an array with elements ['110', 'paris'] so:

array[0] // this is '110'
array[1] // this is 'paris'

Note that if you actually want a number 110 and not a string '110' then you should use parseInt:

parseInt(array[0], 10) // this is 110

Full example:

var str = '110|paris';
var array = str.split('|');
var value = parseInt(array[0], 10);
var city = array[1];

Now value is 100 (number) and city is 'paris' (string).
