The below method returns any key from A-Z and 0-9 and when I pressed shift key + 4 its returns the same code 52.

function keyUpEvent(e)//onkeyup event
{
    var chr = String.fromCharCode(e.keyCode);//converts the keycode into a character
    alert(chr);//alerts the character
}

But I need to show the $ or % when the respective key with bination of shift key is pressed.

• jquery
• keypress
• onkeyup

i'd go with something like this:

$(function () {
    $(document).on('keyup keydown keypress', function (event) {
        if (event.keyCode == 52 && event.shiftKey) {
            alert('foo');
        }
    });
});

Key codes relate only to keys. $ is a character, achieved through two keys, Shift and 4. There is no key code explicitly for $ when using onkeydown

Edit: It was pointed out by Edward that onkeypress uses key binations, and does have keycode's for binations. Learn something new every day :)

Here's some code, edited from the onkeydown example provided by the MDN, to detect keypress keycodes.

Here's the fiddle updated to be Firefox-friendly, using help from this S.O. post. The JQuery solution works too, if you swing that way.

$ is equal to 36.

Here is same S.O thread

You cannot check for two key events at once. You can try e.shiftKey which tells you whether the shift key was being pressed when the event occurred. Try to check:

if(e.keyCode === 53 && e.shiftKey){}

also if you have a text field, than you can attach event on key enter and check for '%'.

In KeyDown event of TextBox, use:

if (e.Shift && e.KeyCode == Keys.4) {
  //Your code here
}
