hx-disinherit
htmx 的默认行为是自动“继承”许多属性:也就是说,诸如 hx-target 之类的属性可以放在父元素上,并且所有子元素都将继承该目标。
hx-disinherit
属性允许您控制这种自动属性继承。一个示例场景是允许您在页面的 body
元素上放置一个 hx-boost
,但覆盖页面特定部分的行为以允许更具体的行为。
htmx 按以下方式评估属性继承
hx-disinherit
时hx-disinherit="*"
此元素的所有属性继承将被禁用hx-disinherit="hx-select hx-get hx-target"
仅禁用一个或多个指定属性的继承<div hx-boost="true" hx-select="#content" hx-target="#content" hx-disinherit="*">
<a href="/page1">Go To Page 1</a> <!-- boosted with the attribute settings above -->
<a href="/page2" hx-boost="unset">Go To Page 1</a> <!-- not boosted -->
<button hx-get="/test" hx-target="this"></button> <!-- hx-select is not inherited -->
</div>
<div hx-boost="true" hx-select="#content" hx-target="#content" hx-disinherit="hx-target">
<!-- hx-select is automatically set to parent's value; hx-target is not inherited -->
<button hx-get="/test"></button>
</div>
<div hx-select="#content">
<div hx-boost="true" hx-target="#content" hx-disinherit="hx-select">
<!-- hx-target is automatically inherited from parent's value -->
<!-- hx-select is not inherited, because the direct parent does
disables inheritance, despite not specifying hx-select itself -->
<button hx-get="/test"></button>
</div>
</div>
