I need a (javascript compliant) regex that will match any string except a string that contains only whitespace. Cases:
" " (one space) => doesn't match
" " (multiple adjacent spaces) => doesn't match
"foo" (no whitespace) => matches
"foo bar" (whitespace between non-whitespace) => matches
"foo " (trailing whitespace) => matches
" foo" (leading whitespace) => matches
" foo " (leading and trailing whitespace) => matches
This looks for at least one non whitespace character.
/\S/.test(" "); // false
/\S/.test(" "); // false
/\S/.test(""); // false
/\S/.test("foo"); // true
/\S/.test("foo bar"); // true
/\S/.test("foo "); // true
/\S/.test(" foo"); // true
/\S/.test(" foo "); // true
I guess I'm assuming that an empty string should be consider whitespace only.
If an empty string (which technically doesn't contain all whitespace, because it contains nothing) should pass the test, then change it to...
/\S|^$/.test(" "); // false
/\S|^$/.test(""); // true
/\S|^$/.test(" foo "); // true
Try this expression:
/\S+/
\S mean any non-whitespace character.
/^\s*\S+(\s?\S)*\s*$/
demo :
var regex = /^\s*\S+(\s?\S)*\s*$/;
var cases = [" "," ","foo","foo bar","foo "," foo"," foo "];
for(var i=0,l=cases.length;i<l;i++)
{
if(regex.test(cases[i]))
console.log(cases[i]+' matches');
else
console.log(cases[i]+' doesn\'t match');
}

[Am not I am]'s answer is the best:
/\S/.test("foo");
Alternatively you can do:
/[^\s]/.test("foo");
if (myStr.replace(/\s+/g,'').length){
// has content
}
if (/\S/.test(myStr)){
// has content
}

I want to check if a string contains special characters like !##$%^&*.,<>/\'";:? and return true if the string contains atleast one of those chars.
I tried with the following regex,script:
var format = /^[!##$%^&*()_+\-=\[\]{};':"\\|,.<>\/?]*$/;
if( string.match(format) ){
return true;
}else{
return false;
}
If the string contains only the special characters then it returns true , but if the string contains something else like alphanumeric chars ( !example1 , .example2 ) it returns false.
I suggest using RegExp .test() function to check for a pattern match, and the only thing you need to change is remove the start/end of line anchors (and the * quantifier is also redundant) in the regex:
var format = /[ `!##$%^&*()_+\-=\[\]{};':"\\|,.<>\/?~]/;
// ^ ^
document.write(format.test("My#string-with(some%text)") + "<br/>");
document.write(format.test("My string with spaces") + "<br/>");
document.write(format.test("MyStringContainingNoSpecialChars"));
The anchors (like ^ start of string/line, $ end od string/line and \b word boundaries) can restrict matches at specific places in a string. When using ^ the regex engine checks if the next subpattern appears right at the start of the string (or line if /m modifier is declared in the regex). Same case with $: the preceding subpattern should match right at the end of the string.
In your case, you want to check the existence of the special character from the set anywhere in the string. Even if it is only one, you want to return false. Thus, you should remove the anchors, and the quantifier *. The * quantifier would match even an empty string, thus we must remove it in order to actually check for the presence of at least 1 special character (actually, without any quantifiers we check for exactly one occurrence, same as if we were using {1} limiting quantifier).

Your regexp use ^ and $ so it tries to match the entire string. And if you want only a boolean as the result, use test instead of match.
var format = /[!##$%^&*()_+\-=\[\]{};':"\\|,.<>\/?]+/;
if(format.test(string)){
return true;
} else {
return false;
}
Wouldn't it be easier to negative-match alphanumerics instead?
return string.match(/^[^a-zA-Z0-9]+$/) ? true : false;
var specialChars = "<>#!#$%^&*()_+[]{}?:;|'\"\\,./~`-=";
var checkForSpecialChar = function(string){
for(i = 0; i < specialChars.length;i++){
if(string.indexOf(specialChars[i]) > -1){
return true
}
}
return false;
}
var str = "YourText";
if(checkForSpecialChar(str)){
alert("Not Valid");
} else {
alert("Valid");
}
Remove the characters ^ (start of string) and $ (end of string) from the regular expression.
var format = /[!##$%^&*()_+\-=\[\]{};':"\\|,.<>\/?]/;
var format = /[`!##$%^&*()_+\-=\[\]{};':"\\|,.<>\/?~]/;
// ^ ^
document.write(format.test("My #string-with(some%text)") + "<br/>");
document.write(format.test("My string with spaces") + "<br/>");
document.write(format.test("My StringContainingNoSpecialChars"));
Simple solution
let text = "12AB"
const specialChars = `/[!##$%^&*()_+\-=\[\]{};':"\\|,.<>\/?]+/;`
const isSpecialCharsPresent = specialChars.split('').some(char =>
text.includes(char)) // true if present and false if not
console.log(isSpecialCharsPresent) // false
let text = "12AB."
console.log(isSpecialCharsPresent) // true
Check if a string contains at least one password special character:
For reference: ASCII Table -- Printable Characters
Special character ranges in the ASCII table are:
Space to /
: to #
[ to `
{ to ~
Therefore, use this:
/[ -/:-#[-`{-~]/.test(string)
I just did this,
if(string.match(/\W/)){
return true; // Contains at least one special character or space
} else {
return false;
}
You can use this regex for specials chars : /\W/
I took an alternative approuch, without using REGEX, O(n) in performence:
function hasSpecialChars(str) {
const specialCharsSet = new Set("!##$%^&*()_");
for (let letter of str) {
if (specialCharsSet.has(letter)) {
return true;
}
}
return false;
}
You can try this:
regex = [\W_]
It will definitely help you.
I want to have a regular expression in JavaScript which help me to validate a string with contains only lower case character and and this character -.
I use this expression:
var regex = /^[a-z][-\s\.]$/
It doesn't work. Any idea?
Just use
/^[a-z-]+$/
Explanation
^ : Match from beginning string.
[a-z-] : Match all character between a-z and -.
[] : Only characters within brackets are allowed.
a-z : Match all character between a-z. Eg: p,s,t.
- : Match only strip (-) character.
+ : The shorthand of {1,}. It's means match 1 or more.
$: Match until the end of the string.
Example
const regex= /^[a-z-]+$/
console.log(regex.test("abc")) // true
console.log(regex.test("aBcD")) // false
console.log(regex.test("a-c")) // true
Try this:
var regex = /^[-a-z]+$/;
var regex = /^[-a-z]+$/;
var strs = [
"a",
"aB",
"abcd",
"abcde-",
"-",
"-----",
"a-b-c",
"a-D-c",
" "
];
strs.forEach(str=>console.log(str, regex.test(str)));
Try this
/^[a-z-]*$/
it should match the letters a-z or - as many times as possible.
What you regex does is trying to match a-z one single time, followed by any of -, whitespace or dot one single time. Then expect the string to end.
Use this regular expression:
let regex = /^[a-z\-]+$/;
Then:
regex.test("abcd") // true
regex.test("ab-d") // true
regex.test("ab3d") // false
regex.test("") // false
PS: If you want to allow empty string "" to pass, use /^[a-z\-]*$/. Theres an * instead of + at the end. See Regex Cheat Sheet: https://www.rexegg.com/regex-quickstart.html
I hope this helps
var str = 'asdadWW--asd';
console.log(str.match(/[a-z]|\-/g));
This will work:
var regex = /^[a-z|\-|\s]+$/ //For this regex make use of the 'or' | operator
str = 'test- ';
str.match(regex); //["test- ", index: 0, input: "test- ", groups: undefined]
str = 'testT- ' // string now contains an Uppercase Letter so it shouldn't match anymore
str.match(regex) //null
I need a regex that will match the following:
a.b.c
a0.b_.c
a.bca._cda.dca-fb
Notice that it can contain numbers, but the groups are separeted by dots. The characters allowed are a-zA-z, -, _, 0-9
The rule is that it cannot start with a number, and it cannot end with a dot. i.e, the regex should not match
0a.b.c
a.b.c.d.
I have come up with a regex, which seems to work on regex101, but not javascript
([a-zA-Z]+.?)((\w+).)*(\w+)
`
But does not seem to work in js:
var str = "a.b.c"
if (str.match("([a-zA-Z]+.?)((\w+).)*(\w+)")) {
console.log("match");
} else {
console.log("not match");
}
// says not match
Your regex matches your values if you use anchors to assert the start ^ and the end $ of the line.
As an alternative you might use:
^[a-z][\w-]*(?:\.[\w-]+)*$
This will assert the start of the line ^, matches a word character \w (which will match [a-zA-Z0-9_]) or a hyphen in a character class [\w-].
Then repeat the pattern that will match a dot and the allowed characters in the character class (?:\.[\w-]+)* until the end of the line $
const strings = [
"a.b.c",

];
let pattern = /^[a-z][\w-]*(?:\.[\w-]+)*$/i;
strings.forEach((s) => {
console.log(s + " ==> " + pattern.test(s));
});
If the match should not start with a digit but can start with an underscore or hypen you might use:
^[a-z_-][\w-]*(?:\.[\w-]+)*$
Use forward slashes / and paste the regex code between them from online regex testers, when you use JavaScipt.
Here are, what I've changed in your regex pattern:
added ^ at the beginning of your regex to match the beginning of the input
added $ at the end to match the end of the input
removed A-Z and added the i modifier for case-insensitive search (this is optional).
Also, when you use regex101, make sure to select JavaScript Flavor, when creating/testing your regex for JavaScript.
var pattern = /^([a-z]+.?)((\w+).)*(\w+)$/i;
// list of strings, that should be matched
var shouldMatch = [
'a.b.c',
'a0.b_.c',
'a.bca._cda.dca-fb'
];
// list of strings, that should not be matched
var shouldNotMatch = [
'0a.b.c',
'a.b.c.d.'
];
shouldMatch.forEach(function (string) {
if (string.match(pattern)) {
console.log('matched, as it should: "' + string + '"');
} else {
console.log('should\'ve matched, but it didn\'t: "' + string + '"');
}
});
shouldNotMatch.forEach(function (string) {
if (!string.match(pattern)) {
console.log('didn\'t match, as it should: "' + string + '"');
} else {
console.log('shouldn\'t have matched, but it did: "' + string + '"');
}
});
More on regexes in JavaScript
I want to check if a string contains special characters like !##$%^&*.,<>/\'";:? and return true if the string contains atleast one of those chars.
I tried with the following regex,script:
var format = /^[!##$%^&*()_+\-=\[\]{};':"\\|,.<>\/?]*$/;
if( string.match(format) ){
return true;
}else{
return false;
}
If the string contains only the special characters then it returns true , but if the string contains something else like alphanumeric chars ( !example1 , .example2 ) it returns false.
I suggest using RegExp .test() function to check for a pattern match, and the only thing you need to change is remove the start/end of line anchors (and the * quantifier is also redundant) in the regex:
var format = /[ `!##$%^&*()_+\-=\[\]{};':"\\|,.<>\/?~]/;
// ^ ^
document.write(format.test("My#string-with(some%text)") + "<br/>");
document.write(format.test("My string with spaces") + "<br/>");
document.write(format.test("MyStringContainingNoSpecialChars"));
The anchors (like ^ start of string/line, $ end od string/line and \b word boundaries) can restrict matches at specific places in a string. When using ^ the regex engine checks if the next subpattern appears right at the start of the string (or line if /m modifier is declared in the regex). Same case with $: the preceding subpattern should match right at the end of the string.
In your case, you want to check the existence of the special character from the set anywhere in the string. Even if it is only one, you want to return false. Thus, you should remove the anchors, and the quantifier *. The * quantifier would match even an empty string, thus we must remove it in order to actually check for the presence of at least 1 special character (actually, without any quantifiers we check for exactly one occurrence, same as if we were using {1} limiting quantifier).

Your regexp use ^ and $ so it tries to match the entire string. And if you want only a boolean as the result, use test instead of match.
var format = /[!##$%^&*()_+\-=\[\]{};':"\\|,.<>\/?]+/;
if(format.test(string)){
return true;
} else {
return false;
}
Wouldn't it be easier to negative-match alphanumerics instead?
return string.match(/^[^a-zA-Z0-9]+$/) ? true : false;
var specialChars = "<>#!#$%^&*()_+[]{}?:;|'\"\\,./~`-=";
var checkForSpecialChar = function(string){
for(i = 0; i < specialChars.length;i++){
if(string.indexOf(specialChars[i]) > -1){
return true
}
}
return false;
}
var str = "YourText";
if(checkForSpecialChar(str)){
alert("Not Valid");
} else {
alert("Valid");
}
Remove the characters ^ (start of string) and $ (end of string) from the regular expression.
var format = /[!##$%^&*()_+\-=\[\]{};':"\\|,.<>\/?]/;
var format = /[`!##$%^&*()_+\-=\[\]{};':"\\|,.<>\/?~]/;
// ^ ^
document.write(format.test("My #string-with(some%text)") + "<br/>");
document.write(format.test("My string with spaces") + "<br/>");
document.write(format.test("My StringContainingNoSpecialChars"));
Simple solution
let text = "12AB"
const specialChars = `/[!##$%^&*()_+\-=\[\]{};':"\\|,.<>\/?]+/;`
const isSpecialCharsPresent = specialChars.split('').some(char =>
text.includes(char)) // true if present and false if not
console.log(isSpecialCharsPresent) // false
let text = "12AB."
console.log(isSpecialCharsPresent) // true
Check if a string contains at least one password special character:
For reference: ASCII Table -- Printable Characters
Special character ranges in the ASCII table are:
Space to /
: to #
[ to `
{ to ~
Therefore, use this:
/[ -/:-#[-`{-~]/.test(string)
I just did this,
if(string.match(/\W/)){
return true; // Contains at least one special character or space
} else {
return false;
}
You can use this regex for specials chars : /\W/
I took an alternative approuch, without using REGEX, O(n) in performence:
function hasSpecialChars(str) {
const specialCharsSet = new Set("!##$%^&*()_");
for (let letter of str) {
if (specialCharsSet.has(letter)) {
return true;
}
}
return false;
}
You can try this:
regex = [\W_]
It will definitely help you.
We have this simple regular expression:
var regex = \a[bc]*\;
// matches 'ab', 'abb', 'accc'
but this regex also matches 'aa'.
In other words, because the pattern [bc] did not exist, it repeated the 'a'. But the intent was to catch the 'a' then any number of 'b' or 'c'.
How would you apply the * (repeat pattern) so it only acts on the previous character if it matched anything.
No. * is not applied to a in the regex. * is applied to only character class [bc].
You haven't matched the complete string. You have to use ^(starts with) and $(ends with) in your regex.
var regex = /^a[bc]*$/;
// ^ ^
OR use word boundary selector, if you want to match substring in a larger string.
var regex = /\ba[bc]*\b/;
// ^^ ^^
Demo:
var regex = /\ba[bc]*\b/;
document.write("regex.test('a'): " + regex.test('a')); // true
document.write("<br />regex.test('abc'): " + regex.test('abc')); // true
document.write("<br />regex.test('abcab'): " + regex.test('abcab')); // false
document.write("<br />regex.test('aa'): " + regex.test('aa')); // false
// Words in string
document.write("<br /><br />regex.test('this is a adbc'): " + regex.test('this is a adbc')); // true 'a'
document.write("<br />regex.test('this is adbc'): " + regex.test('this is adbc')); // false
