Do a global search for characters NOT inside the brackets [h]
/[^abc]/ is an ECMAScript1 (ES1) feature.
ES1 (JavaScript 1997) is fully supported in all browsers:
| Chrome | IE | Edge | Firefox | Safari | Opera |
| Yes | Yes | Yes | Yes | Yes | Yes |
Use the [abc] expression to find any character BETWEEN the brackets.
Do a global search for characters that are NOT "i" and "s" in a string:
let text = "Do you know if this is all there is?";
let pattern = /[^is]/gi;
Do a global search for the character-span NOT from lowercase "a" to lowercase "h" in a string:
let text = "Is this all there is?";
let pattern = /[^a-h]/g;
Do a global search for the character-span NOT from uppercase "A" to uppercase "E":
let text = "I SCREAM FOR ICE CREAM!";
let pattern = /[^A-E]/g;
Do a global search for the character-span NOT from uppercase "A" to lowercase "e":
let text = "I Scream For Ice Cream, is that OK?!";
let pattern = /[^A-e]/g;
Do a global, case-insensitive search for the character-span that's NOT [a-s]:
let text = "I Scream For Ice Cream, is that OK?!";
let pattern = /[^a-s]/gi;
In JavaScript, a regular expression text search, can be done with different methods.
With a pattern as a regular expression, these are the most common methods:
| Example | Description |
|---|---|
| text.match(pattern) | The String method match() |
| text.search(pattern) | The String method search() |
| pattern.exec(text) | The RexExp method exec() |
| pattern.test(text) | The RegExp method test() |
