This post helps you understand how to use the <fn:split> tag in the JSTL function tags library with code example.
The fn:split function splits a string into an array of substring based on the delimiter provided. This function returns array of strings.
JSTL <fn:split> Syntax:
${fn:split(<string with delimiters>, <delimiter>)}
JSTL <fn:split> Example:
The below code example splits a string with comma (,) as a delimiter. Note that since this function returns an array of strings, we need to use fn:join function to join the individual strings in the array to display.
