$("#username").keyup(function () {


if (this.value.match(/d/g)){


this.value = this.value.replace(/d+/g,'');


}

else {

}

});

Why would you want to limit input? Ok, reworded, why would you want to limit input as it is happening? What stops a person from pasting whatever they want to your field? — GetSet, May 03 '20 at 21:09
I want to limit the username to special characters and numbers. Space character, English character and Thai character will be released. — frankosa, May 03 '20 at 21:14
Wouldn't it be easier to validate after the fact? That is when the field changes event `onchange` then you can check for validity? — GetSet, May 03 '20 at 21:15
Whatever the name is, my point is what purpose is served by preventing the user from typing whatever they want? You can validate after — GetSet, May 03 '20 at 21:18
Use `.replace(/[^\sA-Za-z\u0E00-\u0E7F]+/g, '')`. See https://regex101.com/r/W4Dg3b/1 — Wiktor Stribiżew, May 03 '20 at 21:31

Use input event, so you can also filter pasted text.

$("#username").on("input", function(e) {
  $(this).val(function(i, v) {
    return v.replace(/[^a-z\u0E00-\u0E7F ]/gi, "");
  });
});

<input type="text" id="username">
