If you have worked on projects involved dynamic UI having client side input validations, then you can recall that it is very common practice among QA/testers that they try to copy lots of garbage text to create invalid scenarios and log them as a bug. I will not comment on validity of these kind of issues. Here in this post, I will give you a solution which you can use to solve this problem if it happens to you.
Please note that this will work always. No matter you generate these events with keyboard or mouse.

Detect CUT COPY or PASTE events
To detect these events you need to bind following events in given manner for any input area.
$(document).ready(function() {
$("#textA").bind({
copy : function(){
$('#message').text('copy behaviour detected!');
},
paste : function(){
$('#message').text('paste behaviour detected!');
},
cut : function(){
$('#message').text('cut behaviour detected!');
}
});
});
Try yourself
<html>
<head>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.10.2.min.js"></script>
<style type="text/css">
span{
color:green;
font-weight:bold;
}
</style>
</head>
<body>
<h1>Detect Cut, Copy and Paste with jQuery</h1>
<form action="#">
<label>Text Box : </label>
<input id="textA" type="text" size="50" value="Copy, paste or cut any text here" />
</form>
<span id="message"></span>
<script type="text/javascript">
$(document).ready(function() {
$("#textA").bind({
copy : function(){
$('#message').text('copy behaviour detected!');
},
paste : function(){
$('#message').text('paste behaviour detected!');
},
cut : function(){
$('#message').text('cut behaviour detected!');
}
});
});
</script>
</body>
</html>

Hi Guptha,
These two tabs having the common buttons that button names are “save” and “cancel”.My Question is these two buttons are not needed in the second tab (UserTab).So i want hide those buttons in the second tab.But when i try to hide those buttons in the second tab it is not showing in the first tab.So could you please tell me how to hide those buttons in jquery ?
Always use unique ids for all elements in HTML page. Give the ids to button as tab_1_save, tab_1_cancel, tab_2_save and tab_2_cancel. Now hive whatever you want to hide. Nothing will effect accidentally.
$(“#tab_1_save”).hide();

Thanks in Advance
Really can’t help with this limited information.
please share a post to restrict copy paste using javascript
Why you would like to restrict copy + cut?? Pasting can be made mandatory in some cases where you want user to type whole input text so that he knows what he is typing. e.g. email validations.
window.onload = function() {
var myInput = document.getElementById('myInput');
myInput.onpaste = function(e) {
//Do something here
e.preventDefault();
//return false;
}
}
Please tell ,what will happen if user disables javascript is disabled by user.
Thank you.
Then you can’t do anything.
Thanks for the reply……
