方法

addEventListener

  • addEventListener(type, callback, options?): void

  • Appends an event listener for events whose type attribute value is type. The callback argument sets the callback that will be invoked when the event is dispatched.

    The options argument sets listener-specific options. For compatibility this can be a boolean, in which case the method behaves exactly as if the value was specified as options's capture.

    When set to true, options's capture prevents callback from being invoked when the event's eventPhase attribute value is BUBBLING_PHASE. When false (or not present), callback will not be invoked when event's eventPhase attribute value is CAPTURING_PHASE. Either way, callback will be invoked if event's eventPhase attribute value is AT_TARGET.

    When set to true, options's passive indicates that the callback will not cancel the event by invoking preventDefault(). This is used to enable performance optimizations described in § 2.8 Observing event listeners.

    When set to true, options's once indicates that the callback will only be invoked once after which the event listener will be removed.

    If an AbortSignal is passed for options's signal, then the event listener will be removed when signal is aborted.

    The event listener is appended to target's event listener list and is not appended if it has the same type, callback, and capture.

    参数

    返回 void

after

  • after(...nodes): void

  • Inserts nodes just after node, while replacing strings in nodes with equivalent Text nodes.

    Throws a "HierarchyRequestError" DOMException if the constraints of the node tree are violated.

    返回 void

appendChild

appendData

before

  • before(...nodes): void

  • Inserts nodes just before node, while replacing strings in nodes with equivalent Text nodes.

    Throws a "HierarchyRequestError" DOMException if the constraints of the node tree are violated.

    参数

    • 动态参数...nodes: (string | Node)[]

    返回 void

cloneNode

  • cloneNode(deep?): Node

  • Returns a copy of node. If deep is true, the copy also includes the node's descendants.

    参数

    • 可选deep: boolean

contains

  • contains(other): boolean

  • Returns true if other is an inclusive descendant of node, and false otherwise.

    参数

    返回 boolean

deleteData

dispatchEvent

  • dispatchEvent(event): boolean

  • Dispatches a synthetic event event to target and returns true if either event's cancelable attribute value is false or its preventDefault() method was not invoked, and false otherwise.
