Disable linebreaks in HTML textarea

问题

with CSS or any other way, is it possible to disallow newlines in a HTML textarea? So basically I want nothing to happen when the user presses "enter".

回答1:

Using jQuery, you could do it like this:

$(document).ready(function() {
  $("#t_area").keypress(function(event) {
    if(event.which == '13') {
      return false;
    }
  });
});

<textarea id="t_area"></textarea>

I would also strip out any newlines using PHP or ASP or whatever server-side scripting language you have access to as well to be completely thorough.

回答2:

its posible with wrap="soft,hard, or off
