JAVASCRIPT

JAVASCRIPT substring() METHOD

The substr() method extracts characters from a string between two specified positions and returns the extacted part as new string.

The substring() method takes a required starting position as a number and an optional stop position. If the optional stop position is not specified, then the extracted string will be from starting position to end of main string.

Remember: the first position of a string is 0 and not 1.

The general format is:

string.substring(startposition, stopposition[optional]);

Example Without The Optional Stop Position:

<script type="text/javascript">

var text="My name is John Doe.";

document.write(text.substring(3));

</script>

Will output:



Example With The Optional Stop Position:

<script type="text/javascript">

var text="My name is John Doe.";

document.write(text.substring(3, 4));

</script>

Will output:
