Using regular expressions in JavaScript. Regular expressions are used with the RegExp methods test() and exec() and with the String methods match() , replace() , search() , and split() . Executes a search for a match in a string. It returns an array of information or null on a mismatch.
To match a character having special meaning in regex, you need to use a escape sequence prefix with a backslash ( \ ). E.g., \. matches "." ; regex \+ matches "+" ; and regex \( matches "(" . You also need to use regex \\ to match "\" (back-slash).
In the context of regular expressions, a character class is a set of characters enclosed within square brackets. It specifies the characters that will successfully match a single character from a given input string.
Regular expressions are patterns that provide a powerful way to search and replace in text. In JavaScript, they are available via the RegExp object, as well as being integrated in methods of strings.
Try this:
/[A-Za-z\u00C0-\u00D6\u00D8-\u00f6\u00f8-\u00ff]+/g
Below java script function will work fine, you can add number as well.
function myFunction() {
var str = "xq234";
var allowChars = "^[a-zA-ZÀ-ÿ]+$";
var res = str.match(allowChars);
if(!str.match(allowChars)){
res="true";
}
else {
res="false";
}
document.getElementById("demo").innerHTML = res;`enter code here`
