I have a text area which doesn't have max length. In that text area i am restricting the symbols and junk characters on keypress by checking with charcode>160 and able to restrict the junk symbols and characters. But when i trying to stop copy pasting the junk values, it does n't happen. Below I have copied the code which i tried for keypress and copy paste.

$("input[type=text], textarea").bind("keypress paste", function(event) {
        if (event.charCode>160 || !event.charCode) {
            alert("Not allowed characters/symbols");
            event.preventDefault();
        }
})

and some junk characters -- !íßÓÜØúƤ etc.

You may be better to create a regex which includes the allowed characters and removing those that aren't listed. – Rory McCrossan Jan 29 '16 at 09:33

there's no event.charCode when I paste 10 characters – Gavriel Jan 29 '16 at 09:35

Additional to Rory's comment, use `oninput` instead of `keypress` and `paste`. It takes care of a dropped text too. – Teemu Jan 29 '16 at 09:48
Rory and Teemu, do you have any working example? – GMan Jan 29 '16 at 10:09
[A fiddle](https://jsfiddle.net/9129kwx2/). You can construct the regexp to contain any characters you need. – Teemu Jan 29 '16 at 12:14
