In my project i have text field that only take numeric value.but when I copy an alphabets using ctl+c and paste using ctl+v it will allow the alphabets in the text field.So I disable the the copy and paste using the following code.

$('input').bind('copy paste', function(e) {
 e.preventDefault();
});

But I want to prevent only alphabets.That means I want copy paste numeric value not alphabets.

    Try this function. This may not be what you are looking for but you can do something out of this. I have done this earlier and posted on my blog.

    JS:

     $(function(){  
                $(".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;  
                     }  
                );  
                $(".numericOnly").bind("paste",function(e) {  
                     e.preventDefault();  
                });  
                $(".numericOnly").bind('mouseenter',function(e){  
                      var val = $(this).val();  
                      if (val!='0'){  
                           val=val.replace(/[^0-9]+/g, "")  
                           $(this).val(val);  
                      }  
                });  
           });

    HTML:

     <body>  
       <input type="text" id="textBox" class="numericOnly" />  
 </body>

    This will allow you to enter only numeric values only. You can’t even copy paste and drag drop.
