The RegExp [^0-9] Expression in JavaScript is used to search any digit which is not between the brackets. The character inside the brackets can be a single digit or a span of digits.
Syntax:
/[^0-9]/
or
new RegExp("[^0-9]")
Syntax with modifiers:
/[^0-9]/g
or
new RegExp("[^0-9]", "g")
Example 1: This example searches the digits which are not present between [0-4] in the whole string.
Javascript
function geek() { let str1 = "123456790"; let regex4 = /[^0-4]/g; let match4 = str1.match(regex4); console.log("Found " + match4.length + " matches: " + match4);}geek(); |
Found 4 matches: 5,6,7,9
Example 2: This example searches the digits which are not present between [0-9] in the whole string and replaces the characters with hash(#).
Javascript
function geek() { let str1 = "128@$%"; let replacement = "#"; let regex4 = new RegExp("[^0-9]", "g"); let match4 = str1.replace(regex4, replacement); console.log("Found " + match4.length + " matches: " + match4);}geek(); |
Found 6 matches: 128###
