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

Question

How can I disable Paste (Ctrl+V) option using jQuery in one of my input text fields?

Answer 1

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();
    });
});

Answer 2

You can catch key event :

function checkEventObj ( _event_ ){
    // --- IE explorer
    if ( window.event )
        return window.event;
    // --- Netscape and other explorers
    else
        return _event_;
}

document.keydown = function(_event) {
    var e = checkEventObject(_event);

    if( e.ctrlKey && (e.keyCode == 86) )
        window.clipboardData.clearData();
}

Not tested but, could help.

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

I tried this in my Angular project and it worked fine without jQuery.

<input type='text' ng-paste='preventPaste($event)'>

And in script part:

$scope.preventPaste = function(e){
   e.preventDefault();
   return false;
};

In non angular project, use 'onPaste' instead of 'ng-paste' and 'event' instesd of '$event'.

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;
});
