I need to prevent the single and double quotes from being pasted in a text area in javascript

HTML

<textarea rows=10 cols=10 id=txtTest></texarea>

Preventing the single and double quotes on keydown

$('#txtTest').on('keydown', function(e){

    if(e.shiftKey && e.keyCode == 222 || e.keyCode == 222){

        e.stopPropagation();

    }

});

How to prevent the same when the text is pasted. (ctrl + v)

You'll need to trap more than the keydown event - Ctrl+V or right-click and paste can also insert characters (well and the older Shift+Insert). Depending on your usage, you may want to remove unwanted characters before submission. However, if you want it on the event, then trap all events and replace the text with the cleared text, depending on the event type.

$('#txtTest').val($('#txtTest').val().replace(/[']/g, ''));

That'll remove all the single and double quotes (though not smart quotes).
