jQuery添加 <br> 单击后输入文本区域

Question

I'm trying to append a br tag after a user click enter in a textarea field.

This is what I'm trying to do:

if (e.keyCode == 13)
{
   $('.myTextarea').replace('\n', "<br />");       
}

Can anyone tell me what I'm doing wrong?

Answer 1

You should get value in the textarea. See the val document http://api.jquery.com/val/ .

Try this,

if (e.keyCode == 13)
{
    $('.myTextarea').val(function(i, v) {
        return v.replace('\n', '<br/>');
    }
}
