在我根本无法弄清楚的关于迷路开始标签的错误中 [英] Getting error about a stray start tag that I simply can't figure out

问题描述

底部有一个

我有此代码:

<select name="archive-dropdown" onchange="document.location.href=this.options[this.selectedIndex].value;">
    <option value="">Select Month</option> 
    <option value='http://www.example.com?m=201512'>
    <span style="text-decoration: underline; color: blue;">
        December 2015 &nbsp;(4)
    </span>
    </option>
</select>

当我用Firebug检查HTML时，没有span标签.如果我通过Firefox查看页面源，则span开始标记和结束标记以红色显示，表明有问题.

When I inspect the HTML with Firebug, the span tag is not there. If I look at the page source, via Firefox, the span start tag and end tag are displayed in red indicating that something is wrong.

将光标悬停在红色代码上方，会给我:流浪开始标签"span"

Hovering the cursor over the red code gives me: Stray start tag "span"

如果我通过验证程序运行页面，则不会发现错误.

If I run the page through a validator, no errors are found.

也许选项标签中不允许使用span标签?

Perhaps a span tag is not allowed in a option tag???

但是，为什么验证器不标记它呢?

But then, why doesn't the validator not flag it???

编辑* * * * 关于验证器的信息，我再次看了一眼，发现我正在使用CSS验证器.

EDIT * * * * NIX THE BIT ABOUT THE VALIDATOR, I just looked again and found I was using the CSS validator.

我通过标记验证程序运行页面并得到:

I ran the page through the markup vaidator and got:

错误:杂散起始标签跨度.

Error: Stray start tag span.

从273行的第80列开始；到第273行第134列

From line 273, column 80; to line 273, column 134

m = 201512'>< span style ="text-decoration:下划线；颜色: 蓝色；> Decem

m=201512'><span style="text-decoration: underline; color: blue;"> Decem

有什么想法吗?

推荐答案

MDN选项:

允许的内容带有最终转义字符(例如é)的文本.

Permitted content Text with eventually escaped characters (like é).

不允许跨度，只能是文本.如果要设置文本样式，则需要查看不是标准元素的JavaScript/CSS解决方案.

No spans are permitted, it is text only. If you want to style the text, you need to look at a JavaScript/CSS solution that is not a standard element.
