chrome用F12看的html

<html xmlns="http://www.w3.org/1999/xhtml">

    </head>
    
    <body>
        Hello World by string
        <br>
        Hello World by Variables
        <meta http-equiv="content-type" content="text/html; charset=utf-8">
        <title>
        </title>
        <form method="post" action="./index.aspx" id="form1">
            <div class="aspNetHidden">
                <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="O9WYoaTC5iwbsFsB2mCEOnqz68K/nxGNnlZpDQrH7RPw/gHG3Z12Y/YwMo15r4sddiL2iIJAvMBQMvr5vJaHZ8znO/ZowoGE8Lt/xVcxZuE=">
            </div>
            <div class="aspNetHidden">
                <input type="hidden" name="__VIEWSTATEGENERATOR" id="__VIEWSTATEGENERATOR"
                value="90059987">
            </div>
            <div>
                <span id="message">
                </span>
            </div>
        </form>
    </body>

</html>

Q:為什麼head的東西跑到body內了？(如<title>、<meta>)

最佳解答

其實你仔細看Chrome的Sources頁籤

它原始長這樣

Hello World by string<br>Hello World by Variables

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>

</title></head>
<body>
    <form method="post" action="./WebForm1" id="form1">
<div class="aspNetHidden">
<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="97jk6dKQ23Tl/BEXuw8iffm9h6XiskHKWbsN8+zy95WX64LFH4cORkqYphXFjLfWA+Jh7SEOUQSQAu+DxKDYMRitDgJuCvxWyRe7mF58SzM=" />
</div>

<div class="aspNetHidden">

	<input type="hidden" name="__VIEWSTATEGENERATOR" id="__VIEWSTATEGENERATOR" value="C687F31A" />
</div>
        <div>
            <span id="message"></span>
        </div>
    </form>
</body>
</html>

由於你輸出Hello World by string字串讓整個HTML結構異常, Chrome會再整理成它可以理解的格式
