How to disable Paste (Ctrl+V) with jQuery?

Solution 1:

This now works for IE FF Chrome properly... I have not tested for other browsers though

$(document).ready(function(){
   $('#txtInput').on("cut copy paste",function(e) {
      e.preventDefault();
   });
});

Edit: As pointed out by webeno, .bind() is deprecated hence it is recommended to use .on() instead.

Solution 2:

Edit: It's almost 6 years later, looking at this now I wouldn't recommend this solution. The accepted answer is definitely much better. Go with that!

This seems to work.

You can listen to keyboard events with jQuery and prevent the event from completing if its the key combo you are looking for. Note, check 118 and 86 (V and v)

Working example here: http://jsfiddle.net/dannylane/9pRsx/4/

$(document).ready(function(){
    $(document).keydown(function(event) {
        if (event.ctrlKey==true && (event.which == '118' || event.which == '86')) {
            alert('thou. shalt. not. PASTE!');
            event.preventDefault();
         }
    });
});

Update: keypress doesn't fire in IE, use keydown instead.

Solution 3:

As of JQuery 1.7 you might want to use the on method instead

$(function(){
    $(document).on("cut copy paste","#txtInput",function(e) {
        e.preventDefault();
    });
});

Solution 4:

jQuery('input.disablePaste').keydown(function(event) {
    var forbiddenKeys = new Array('c', 'x', 'v');
    var keyCode = (event.keyCode) ? event.keyCode : event.which;
    var isCtrl;
    isCtrl = event.ctrlKey
    if (isCtrl) {
        for (i = 0; i < forbiddenKeys.length; i++) {
            if (forbiddenKeys[i] == String.fromCharCode(keyCode).toLowerCase()) {
                 return false;
            }
        }
    }
    return true;
});
