How do I split a string with multiple separators in JavaScript? Are you trying to split into both commas and spaces and other things? But not getting success!. Don't worry, I'll give you the best solution for you.

JavaScript split Examples

Separate parts from a string with the split function. Split into characters, strings, and patterns. You can use javascript split string by comma also.

Consider a string that has many parts. It has a delimiter character that we want to split upon. With split() in JavaScript, we have many ways to do this.

Syntax

string.split(separator, limit)

Parameter Values

There are two parameter separators and limits. Both fields are very important. Look at this, how to use:

Separator: Optional field. Specifies the character, or the regular expression, to use for splitting the string. The entire string will be returned. It's works with javascript split on multiple characters.

If it has multiple characters, then the sequence of the entire character must be found to split.

Limit: Optional field. An integer that specifies the number of splits, items after the split limit will not be included in the array list.

When found, a separator is removed from the string, and the substrings are returned in an array. If a separator is a regular expression with capturing parentheses, then each time separator matches, the results of the capturing parentheses are spliced into the output array.

Removing spaces from a string

In the following example, split() looks for spaces, if either is a single or more than one spaces are there. When found, removes the spaces from the string. Then the name list is the array returned as a result of split().

Input

var snippets = "In the following example, split() looks for spaces";
var strings = snippets.split(' ');
strings.forEach(myFunction);

function myFunction(item, index) {
  document.getElementById("result").innerHTML += index + ":" + item + "<br>";
}

Output

In
the
following
example,
split()
looks
for
spaces

<div id="result"></div>
<script>

var snippets = document.getElementById("snippets").innerHTML;
var strings = snippets.split(/[;,—]+/);
strings.forEach(myFunction);

function myFunction(item, index) {
  document.getElementById("result").innerHTML += index + ":" + item + "<br>";
}

</script>

</body>
</html>

Output

Name and territory of the; Union.—(1) India, that is Bharat, shall be a Union of States.

0:Name and territory of the
1: Union.
2:(1) India
3: that is Bharat
4: shall be a Union of States.

With a regular expression, we can treat multiple delimiters as a single one. This eliminates empty entries.

The best approach is the simplest. With a single character delimiter, we can write simple code to split the string. Sometimes a regular expression is needed.
