Replace value after split in javascript

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?

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"

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

or using regular expressions

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