Question

我有contenteditable div，我想按Enter键，在文本中添加new line字符。

我这样做：

$("#editable").on("keydown", function(e) {
    if (e.keyCode === 13) {
        document.execCommand('insertHTML', false, '\n');
    }
});

这样做有效，但这也会在文本中添加<br>标记（并在chrome <div>标记中添加）

我需要阻止在输入时添加此标签。

我知道两种方式：

1）使用preventDefault()方法，但是使用此方法，用户需要按两次Enter键进行换行。这很糟糕。

2）使用replace()方法从全文中删除此标记，但在这种情况下，所有这些标记（如果用户在文本中特别输入）也将被删除，因此这也是不好的方法。

如何解决这个问题？
