- The substring() method extracts the characters from a string, between two specified indices, and returns the new sub string.
- This method extracts the characters in a string between "start" and "end", not including "end" itself.
- If "start" is greater than "end", this method will swap the two arguments, meaning str.substring(4, 1) == str.substring(1, 4).
- If either "start" or "end" is less than 0, it is treated as if it were 0.
- The substring() method does not change the original string.
Code:-
- <html>
- <head>
- <meta name="viewport" content="width=device-width, initial-scale=1">
- </head>
- <body>
- <h1>substring()</h1>
- <input type="button" onclick="strfun();" value="Get Answer">
- <script>
- function strfun()
- {
- var str = "abcdefghijkl";
- alert(str.substring(4, 5)); //Split from 4th to 5th character.
- }
- </script>
- </body>
- </html>
