允許「輸入」鍵工作，但沒有給出破折線

Question

嗨，我需要實現這個破折線在這裏工作，因爲你可以輸入enter，但是在你再次輸入沒有給出破折線。

我使這個小提琴http://jsfiddle.net/FPN9w/

這裏是JS代碼。

$(function() { 
    //you have to escaped the - character in a character class 
    var cleanRx = /[^a-zA-Z0-9 áéíóúÁÉÍÓÚÜüñѨ´,.¿?%&$!¡ªº#"()\-_\/]/g; 

    $('#title').keyup(function (e) { 
     var which = e.which; 

     //avoid useless replacements when <- and -> keys are pressed 
     if (which === 39 || which === 37) return; 

     this.value = this.value.replace(cleanRx, ''); 

    }).trigger('keyup'); //perform replacement on initial content (remove if uneeded) 

    $('#description1').keyup(function (e) { 
     var which = e.which; 

     //avoid useless replacements when <- and -> keys are pressed 
     if (which === 39 || which === 37 || which === 13) return; 

     this.value = this.value.replace(cleanRx, ''); 

    }).trigger('keyup'); //perform replacement on initial content (remove if uneeded) 

});

添加該代碼JS

$('#description1').keydown(function(event){ 
    if(event.keyCode == 13) { 
     event.preventDefault(); 
     return false; 
    } 
}); 

這是你更新的jsfiddle http://jsfiddle.net/pratbhoir/FPN9w/3/
