How can I split each string based upon when a "↵" is displayed?

I tried using:

for (i in result1) {
    var res_split=result1[i].split("\n")
};

The above function yields only:

["Edition", "© 2016 Cable News Network. Turner Broadcasting System, Inc. All Rights Reserved."]

Not what I am going for!

You're destroying your res_split each time, that's why you have the last line's result only... — Enissay

Go for this :

var result1 = ["string\nstring1"];

var res_split = [];
for (i in result1) {
  res_split.push(result1[i].split(/(\r\n|\n|\r)/gm));
}
console.log(res_split);

It'll try every kind of line break

Better use [\r\n]+

Blag Over a year ago

@Enissay no, cause it can be mac / unix or win line break and with a class you'll add more or less than needed. (aka \r\n\r\n => 1 line break instead of 2 )

@Lance by the way, could you put the declaration of var result1 ? we can't try it without...

Changed var resplit[]; to var res_split=[]; and everything worked! Thank you!

Try

var res_split=[];

for(i in result1) { res_split.push(result1[i].split("\n"));  }

Otherwise each time new value assigned and old value replaced.

You are not appending your res_split array. You are replacing it for every iteration. Try the following:

var res_split = [];

for (var i in result1) {
    res_split.push(result1[i].split("\n"));
}

The += is yielding: Uncaught SyntaxError: Unexpected token +=

MinusFour Over a year ago

split gets you an array and "" + [] isn't what OP needs.

@Gideon Now it is outputting: Uncaught SyntaxError: Unexpected token .

var res_split=[];
for (i in result1) {
    res_split.push(result1[i].split(/(\r\n|\n|\r)/gm));
};
