Replace value after split in javascript

Question

Suppose the string:

"The | dog";

If I do in js:

var string;
string = "The | dog | and | apple";
string.split("|")[1];

The returns will be "dog". I should like to replace that, somelike this:

string.split("|")[1] = "cat";

And the string pass to be "The | cat | and |apple", knowing as string "dog" can be another value too.

It's possible?

It is possible, but not in one expression. You could use replace() though. — elclanrs

@cl3m - a .replace does not replace all instances. It only replaces the first instance. You can use .replaceAll — Nikhil Nanjappa

You can replace the individual array element and then use join to make a string again:

var string = "The | dog";

var DELIMITER = " | ";
var parts = string.split(DELIMITER);
parts[1] = "cat";
string = parts.join(DELIMITER);

// string === "The | cat"

Humm, okay, and if the String be "The | dog | and | apple", if I could want replace dog for another value, knowing dog can be another string too

Yeah, it will just replace the contents between the first and second DELIMITER. If you wanted to replace a different position you could change parts[1] to something else.

var arr=string.split('|');
arr[1]='cat'
var s=arr.join('|');

or using regular expressions

string.replace(/^([^\|]+)\|([^\|]+)/g,'$1|cat')
