Question

我有一个UIWebView，我正在使用原生键盘创建自定义文本编辑器。

我正在尝试检测本机键盘上何时按下返回按钮。我尝试了以下代码：How to detect keyboard enter key?以及customize return key但未能成功。我如何获得回报？

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>

<link rel="stylesheet" type="text/css" href="quill.snow.css">
<link rel="stylesheet" type="text/css" href="quill.bubble.css">
<link rel="stylesheet" type="text/css" href="quill.core.css">
<link rel="stylesheet" type="text/css" href="style.css">
<meta charset="utf-8">
</head>
<body onKeyPress="return returnKeyPressed(event)" style="padding-top:0px;margin-top:0px;">
<div id="wrap">
<div id="editor-container" style="padding:0px;margin-top:0px;font-family:'GothamPro-Light';font-size: 15px;"></div>
</div>
<script type="text/javascript" src="quill.core.js"></script>
<script type="text/javascript" src="quill.min.js"></script>
<script type="text/javascript" src="quill.js"></script>
<script type="text/javascript" src="jquery.min.js"></script>
<script type="text/javascript" src="ios_note_editor.js"></script>
</body>
</html>

的.m

//Not being called
-(BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType{
    NSLog(@"webView shouldStartLoadWithRequest");
}

body onKeyPress更改为onKeyDown时会解决问题。一个字头疼的小时
