Disable Copy and Paste of text in Textbox using Jquery
The following example shows when client want to restrict the users from copy/paste in textbox.
I have a textbox 'loanamount'. Copy/paste can do in two ways i.e. Ctrl+V (or) with mouse right click. Now I want restrict the users from copy/paste in this textbox. For this copy below code into your page.
[javascript]
<script type="text/javascript">
$(function () {
// on Key Press event restrict to enter characters
$(".numericOnly").bind('keypress', function (e) {
if (e.keyCode == '9' || e.keyCode == '16') {
return;
}
var code;
if (e.keyCode) code = e.keyCode;
else if (e.which) code = e.which;
if (e.which == 46)
return false;
if (code == 8 || code == 46)
return true;
if (code < 48 || code > 57)
return false;
}
);
// this event will fire on (Ctrl+v) and it will disable
$(".numericOnly").bind("paste", function (e) {
e.preventDefault();
});
// this event will fire, when your trying to paste with mouse right click and it will disable
$(".numericOnly").bind('mouseenter', function (e) {
var val = $(this).val();
if (val != '0') {
val = val.replace(/[^0-9]+/g, "")
$(this).val(val);
}
});
});
</script>
