允许数字并仅在内容可编辑的div按键上输入

Question

Hey guys i'm creating a content editable div and it should accept numbers and enter key only on every key press is it possible? Thanks

Update

if(event.keyCode >= 48 || event.keyCode <= 57){
   if ( event.keyCode == 13 ) {
   }
} else {
    return false;
}

On my code it's accepting numbers only but not the enter key.

Answer 1

Proper code is:

if ((event.keyCode >== 48 && event.keyCode <== 57) || event.keyCode === 13) {
  // do something with this information
} else {
  return false;
}

You are expecting key (between 48 AND 57) OR 13. Problem was that your first condition is between 48 and 57 and then you check for 13 inside that block, which would mean between 48 and 57 and exactly 13 which is impossible situation.

Answer 2

Just put this in any tag( ie. <span> )...

onKeypress="if(event.keyCode < 48 || event.keyCode > 57){return false;}"

and it will not accept any characters.
