Question

I have to prevent Coldfusion\'s default list delimiter \',\' from being entered into a form input array. I am new to using javascript for validation purposes, and have never tri

Answer 1

I replaced the name[] .live() event.which = 126; to event.originalEvent.keyCode=126;

var regExComma = /,/;
$("[name='name[]']").live("keypress",function(event){
     if(regExComma.test(String.fromCharCode(event.which)){
       //this line works as expected. and will swap out the value on keypress.
       if(event.originalEvent.keyCode){
         event.originalEvent.keyCode=126;
       }else if(event.originalEvent.charCode){
         event.originalEvent.charCode=126;
       }
     }
});
