在 UIWebview 中检测 return 按钮 (iOS)

Question

我有一个 UIWebView，我正在使用本机键盘创建自定义文本编辑器。

我正在尝试检测何时按下本机键盘上的 return 按钮。我尝试过以下代码：How to detect keyboard enter key? as well as customize return key 但未能成功。如何捕获 return?

html:

<!DOCTYPE html>
<html>
<head>
<title>iOS Note Editor</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no">

<script>
    function returnKeyPressed(event){
        if(window.event.keyCode == 13) document.location = "returnkeypressed:";
            return true;
        }
    }
</script> 

<style type="text/css">
    html, body {height: 100%;}
    body {
        margin: 0;
    }
#wrap {
    height: 100%;
    width: 100%;
    overflow-y: scroll;
    -webkit-overflow-scrolling: touch;
}

</style>
