Cant Copy or paste using ctrl+c ctrl+v

[anish.too.cool]

i have a form in which in one textbox i am restricting user to enter chars only numbers. using the below javascript

Code: Select all

 $('#practiceNPI').bind('keypress', function (e) {
        
        
        var k = e.which;
        var ok = k >= 48 && k <= 57 || k == 01//select
            || k == 0
            || k == 8                                 
        ;  

        if (!ok) {
            e.preventDefault();
      
       }
    });

By doing this every thing works well but the only ISSUE is with mozilla where i cant use keybord shortcut to copy paste or select
for ex:- try to copy paste in this field by ctrl+v or ctrl+c http://jsfiddle.net/lesson8/HkEuf/1/

Plz help.. want to use that function...Thx in Adv..

I think you should find out which key codes are ctrl-c/ctrl-v and let them pass.
01 seems to be ctrl-A so ctrl-c is 03 and ctrl-v is 22 (or 23).

Keyboard event object properties and behaviour lack standardisation, with the Level 3 Event specification still only a working draft. No surprise you'vel come across browser dependent differences in keyboard event handling. For the record, the "which" property of a keyboard event does not currently appear in the Level 3 working draft, the nearest property being event.code which is supposed to be of type string and giving the Unicode value of a key pressed.

But for the purposes of this case, e.which is giving the value of the key pressed without consideration of modifier keys (alt or ctrl) pressed. I got your JSFiddle case to work (I think as expected) in Firefox by adding a line to let control keys through:

Code: Select all

$(document).ready(function () {
  //called when key is pressed in textbox
  $("#quantity").keypress(function (e) {
    // let the browser process control keys 
     if(e.ctrlKey)
          return true;
     //if the letter is not digit then display error and don't type anything
     if (e.which != 8 && e.which != 0 && (e.which < 48 || e.which > 57)) {
        //display error message
        $("#errmsg").html("Digits Only").show().fadeOut("slow");
               return false;
    }
   });
});
