在Firefox中的文件输入标签 [英] Label for File input in firefox
问题描述
当我添加一个表单输入的标签时,我通常可以点击标签,它会将我引用到相应的输入(见下文)。
When I add a label the a form input, I can normally click the label and it will refer me to the appropriate input (see below).
<label for="input">Label</label><input type="text" id="input"/>
但是,当我试图用文件输入完成同样的操作时,标签上的点击被忽略。这是一个错误?一个功能?还有什么办法可以完成这个吗?
However, when I try to accomplish the same with a file input, the click on the label gets ignored. Is this a bug? A "feature"? And is there any way to still accomplish this?

推荐答案
更确切地说,这可能是FF中的一个错误(而不是其他的一个额外的特性),因为这个行为通常应该包含在HTML 4规范中:
当LABEL元素获得焦点时,它将焦点传递给其关联的控件。举例来说,请参阅以下关于访问键的部分。
More precisely, this is probably a bug in FF (rather than an extra feature in the others), because this behavior should usually be included according to the HTML 4 spec: When a LABEL element receives focus, it passes the focus on to its associated control. See the section below on access keys for examples.
当前的HTML规范更细微,但是确实表明它什么也不做(这是iOS中的预期行为) 。
The current HTML spec is more nuanced, but does indicate the possibility that it do nothing (this is the expected behavior in iOS).
