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 Commented Mar 31, 2016 at 17:20 -

Can't you just use
.replace('dog', 'cat')? – cl3m Commented Mar 31, 2016 at 17:20 - This is one simple example, in produce i need to use split and I don't know the value, can be 123 or 456 and more...then, did I can't to do with replace – BrTkCa Commented Mar 31, 2016 at 17:22

@cl3m - a
.replacedoes not replace all instances. It only replaces the first instance. You can use.replaceAll– Nikhil Nanjappa Commented Apr 14, 2023 at 15:14

Reset to default 4You 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')
