Splitting strings with Javascript without using for loop

Question

I have following string:

var myString = " https://image.ibb.co/fShWGd/samhily.jpg
                 https://image.ibb.co/iDbDUy/ramhily.jpg
                 https://image.ibb.co/cvbf9y/devoly.jpg  "

ANd I would like to get the following array:

var myArray = ["https://image.ibb.co/fShWGd/samhily.jpg","https://image.ibb.co/iDbDUy/ramhily.jpg", "https://image.ibb.co/cvbf9y/devoly.jpg".

Any ideas on how I would do that?

Tried this:

myArray.split(/(\s+)/).filter( function(e) { return e.trim().length > 0; } );

But I get t when I do console.log(myArray[1])

"I have following string". No you don't. You can't have that code in any javascript anywhere without getting a syntax error. — gforce301

for what you tried, don't you mean to start that line with myString? — Garrett Motzner

You can trim() the string first, then split on whitespace. This saves you from having to loop over the results again map():

var myString = ` https://image.ibb.co/fShWGd/samhily.jpg
                 https://image.ibb.co/iDbDUy/ramhily.jpg
                 https://image.ibb.co/cvbf9y/devoly.jpg  `

console.log(myString.trim().split(/\s+/))

You want to use split to split on the new lines:

var myString = ` https://image.ibb.co/fShWGd/samhily.jpg
                 https://image.ibb.co/iDbDUy/ramhily.jpg
                 https://image.ibb.co/cvbf9y/devoly.jpg  `

var result = myString.split(/\r\n|\n/).map(i => i.trim())

// Result of all items
console.log(result)

// Result of first item in the array
console.log(result[1])

you can use .match with a Regex to match the substrings starting with https and ending with jpg , this will match them even if they are in a single line :

var myString = `https://image.ibb.co/fShWGd/samhily.jpg
                https://image.ibb.co/iDbDUy/ramhily.jpg
                https://image.ibb.co/cvbf9y/devoly.jpg`

var result = myString.match(/https(.*)jpg/g)

console.log(result)

You can use trim split filter and map to achive it.

var myString = ` https://image.ibb.co/fShWGd/samhily.jpg
https://image.ibb.co/iDbDUy/ramhily.jpg
https://image.ibb.co/cvbf9y/devoly.jpg  `

myString.trim().split(/\r\n|\n/).filter(Boolean);

That's not what the OP's input string looks like and this won't work not the OP's string.

A simple reg exp to match anything by spaces would get what you want.

var myString = ` https://image.ibb.co/fShWGd/samhily.jpg
                 https://image.ibb.co/iDbDUy/ramhily.jpg
                 https://image.ibb.co/cvbf9y/devoly.jpg  `

console.log(myString.match(/[^\s]+/g))

Assuming your string has all that whitespace (and therefore would need to be quoted with back-ticks (`)):

var myString = ` https://image.ibb.co/fShWGd/samhily.jpg
                 https://image.ibb.co/iDbDUy/ramhily.jpg
                 https://image.ibb.co/cvbf9y/devoly.jpg  `

myString.trim().split(/\s+/)

First, this gets rid or whitespace on the ends of myString, then it splits on any group of whitespace (\s) characters.
