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

问题

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

回答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.

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.

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();
    });
});

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;
});

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'.

回答6:

The following code will disable cut, copy and paste from full page.

$(document).ready(function () {
   $('body').bind('cut copy paste', function (e) {
      e.preventDefault();
   });
});

回答7:

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

  <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
    <input type="text" id="txtInput" />

回答8:

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

On textbox live event cut, copy, paste event is prevented and it works well.

回答10:

I have tested the issue on chrome browser and it is working for me.Below is a solution for preventing the paste code in your textbox and also prevent the right click.

   $(".element-container").find('input[type="text"]').live("contextmenu paste", function (e) {

    e.preventDefault();
});

回答11:

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

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" />
