I have a text input that I want to execute a function when enter is pressed. I used if condition to determine if enter is pressed but this causes the user not to be able to type in the input box. What can I put in the else condition to allow them to type normally? 

[JsFiddle](https://jsfiddle.net/sbnLupc4/)

```
function addItem(e) {   
    e.preventDefault();                         // Prevent form being submitted
    var text = $('input:text').val();           // Get value of text input
    var itemArr = text.split(',');                                                              
    var lngth = itemArr.length                  

    for(i = 0; i < lngth; i++)                  
    {
        $list.append('<li>' + itemArr[i] + '</li>');    // Add item to end of the list
        updateCount();                                  // Update the count
    } // End loop

    $('#addItems').val('');                         // Empty the text input
    return false;
}

$('#addItems').keypress(function(e) {
    if(e.which == 13) {
        addItem();
    }
    return false;
});

```
