Атрибуты
Элемент поддерживает глобальные атрибуты .
for-
ID labelable-элемента, который находится в том же документе, что и элемент label. Первый такой элемент в документе, ID которого совпадает со значением атрибута
for, становится labeled-контролом для данногоlabel.A label element can have both aforattribute and a contained control element, as long as theforattribute points to the contained control element. formHTML5- The form element with which the label is associated (its form owner). If specified, the value of the attribute is the ID of a
<form>element in the same document. This lets you place label elements anywhere within a document, not just as descendants of their form elements.
This content attribute was removed from the HTML specification on April 28, 2016. However, scripts still have access to a read-onlyHTMLLabelElement.formattribute; it returns the form of which the label's associated control is a member, ornullif the label is not associated with a control or the control isn't part of a form.
Usage notes
- A
<label>can be associated with a control either by placing the control element inside the<label>element, or by using theforattribute. Such a control is called the labeled control of the label element. One input can be associated with multiple labels. - Labels are not themselves directly associated with forms. They are only indirectly associated with forms through the controls with which they're associated.
Examples
Simple label example
<label>Click me <input type="text"></label>
Using the "for" attribute
<label for="username">Click me</label> <input type="text" id="username">

[1] Starting with Gecko 8.0 (Firefox 8.0 / Thunderbird 8.0 / SeaMonkey 2.5), a bubbling click event triggers at most one <label>, and the synthetic click event cannot trigger additional <label>s. In Gecko, a click event will still bubble up past a <label>, while in WebKit or Internet Explorer the click event will stop at the <label>. The behavior prior to Gecko 8.0 (triggering multiple <label>s) caused Firefox to stop responding (see баг 646157).
[2] The HTML specification was updated in April 2016 to deprecate the form attribute. It's still available from script, but its definition has changed: it now returns the associated control's form, or null if there is no associated control (that is, if HTMLLabelElement.control is null). See HTMLLabelElement.form.
This change is implemented in Firefox 49.
