jQuery remove special characters from string and more

replace(/[^a-z0-9\s]/gi, '') will filter the string down to just alphanumeric values and replace(/[_\s]/g, '-') will replace underscores and spaces with hyphens:

str.replace(/[^a-z0-9\s]/gi, '').replace(/[_\s]/g, '-')

Source for Regex: RegEx for Javascript to allow only alphanumeric

Here is a demo: http://jsfiddle.net/vNfrk/

Assuming by "special" you mean non-word characters, then that is pretty easy.

str = str.replace(/[_\W]+/g, "-")

str.toLowerCase().replace(/[\*\^\'\!]/g, '').split(' ').join('-')

Remove numbers, underscore, white-spaces and special characters from the string sentence.

str.replace(/[0-9`~!@#$%^&*()_|+\-=?;:'",.<>\{\}\[\]\\\/]/gi,'');

Demo

this will remove all the special character

 str.replace(/[_\W]+/g, "");

this is really helpful and solve my issue. Please run the below code and ensure it works

var str="hello world !#to&you%*()";
console.log(str.replace(/[_\W]+/g, ""));
