Javascript regex - 删除除分号以外的所有特殊字符

Question

In javascript, how do I remove all special characters from the string except the semi-colon?

sample string: ABC/D Abc;Qwerty

should return: ABCDAbc;Qwerty

Answer 1

You can use a regex that removes anything that isn't an alpha character or a semicolon like this /[^A-Za-z;]/g .

 const str = "ABC/D Abc;Qwerty"; const result = str.replace(/[^A-Za-z;]/g, ""); console.log(result);

Answer 2

var str = "ABC/D A.b.c.;Qwerty";
var result = str.replace(/[^A-Za-z;]/g, "");​​ // 21ABCDAbc;Qwerty
