replace number and symbol with jquery/javascript

Does anyone know how can I replace the number and symbol (excluding dash and single quote)?

Example: if I have a string "ABDHN'S-J34H@#$"; How can I replace the number and symbol to empty and return me value "ABDHN'S-JH" ?

I have the following code to replay all the char and symbol to empty and only return me number

$(".test").keyup(function (e) {
    orgValue = $(".test").val();
    if (e.which != 37 && e.which != 39 && e.which != 8 && e.which != 46) {
        newValue = orgValue.replace(/[^\d.]/g, "");
        $(".test").val(newValue);
    }
});

You could replace symbols by skipping them through keycode value on the keyboard.

Link for keycode values for reglar keyboard: http://www.w3.org/2002/09/tests/keys.html

     $("#your control").bind("keydown keyup", doItPlease);

function doItPlease(e)
 {
// First 2 Ifs are for numbers for num pad and alpha pad numbers
 if (e.which < 106 && e.which > 95)
 {
    return false; // replace your values or return false
 } 
 else if (e.which < 58 && e.which > 47) 
{
    // replace your values or return false
} else {
    var mycharacters = [8, 9, 33, 34, 35 // get your coders from above link];
    for (var i = 0; i < mycharacters.length; i++) {
        if (e.which == mycharacters[i]) {
             // replace your characters or just
             // return false; will cancel the key down and wont even allow it
        }
      e.preventDefault();

}

You can use this regex:

string.replace(/^[a-zA-Z'-]+$/, '')

The caret ^ inside a character class [] will negate the match. This regex will convert all characters other than a-z, A-Z, single quote and hyphen to empty

You should allow only letters, dash and single quotes, like this:

newValue = orgValue.replace(/[^a-zA-Z'-]/g, "");

Anything else will be replaced by "".
