Regex remove all special characters except numbers?

Question

I would like to remove all special characters (except for numbers) from a string. I have been able to get this far

var name = name.replace(/[^a-zA-Z ]/, \"\");
<         


        

Answer 1

to remove symbol use tag [ ]

step:1

[]

step 2:place what symbol u want to remove eg:@ like [@]

[@]

step 3:

var name = name.replace(/[@]/g, "");

thats it

var name="ggggggg@fffff"
var result = name.replace(/[@]/g, "");
console .log(result)

Extra Tips

To remove space (give one space into square bracket like []=>[ ])

[@ ]

It Remove Everything (using except)

[^place u dont want to remove]

eg:i remove everyting except alphabet (small and caps)

[^a-zA-Z ]

var name="ggggg33333@#$%^&**I(((**gg@fffff"
var result = name.replace(/[^a-zA-Z]/g, "");
console .log(result)

Answer 2

This should work as well

text = 'the car? was big and* red!'

newtext = re.sub( '[^a-z0-9]', ' ', text)

print(newtext)

the car was big and red

Answer 3

If you don't mind including the underscore as an allowed character, you could try simply:

result = subject.replace(/\W+/g, "");

If the underscore must be excluded also, then

result = subject.replace(/[^A-Z0-9]+/ig, "");

(Note the case insensitive flag)

Answer 4

To remove the special characters, try

var name = name.replace(/[!@#$%^&*]/g, "");

Answer 5

Use the global flag:

var name = name.replace(/[^a-zA-Z ]/g, "");
                                    ^

If you don't want to remove numbers, add it to the class:

var name = name.replace(/[^a-zA-Z0-9 ]/g, "");
