Hi, I am testing this code to allow a textbox to enter only numbers with Jquery. When I try it in Chrome it works perfect, but the problem arises when I try it from Firefox since it disables the delete key, I can not erase what I write. A help please.
Jquery code that I am using:
$(function(){
$('#input').keypress(function(e){
if(e.charCode < 48 || e.charCode > 57){
return false;
}
});
});
There are pages that block the entry of characters, copy or paste strings, etc. In my opinion, this is a terrible user interface design and it is much better to validate the entry of information and display a message if it is not correct. There are also plugins to obtain only numeric fields. But hey, this works:
$(function(){
$('#input').keypress(function(e){
console.log(e.charCode);
if ((e.charCode >= 48 && e.charCode <= 57) || (e.charCode == 0)) {
return true;
} else {
return false;
}
});
});
