方法

add

• add(element, before?): void

• Adds an element to the areas, controlRange, or options collection.

  参数

  • element: HTMLOptGroupElement | HTMLOptionElement

    Variant of type Number that specifies the index position in the collection where the element is placed. If no value is given, the method places the element at the end of the collection.
  • 可选before: null | number | HTMLElement

    Variant of type Object that specifies an element to insert before, or null to append the object to the collection.

  返回 void

addEventListener

• addEventListener<K>(type, listener, 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.

  返回 void
• addEventListener(type, listener, options?): void

  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.
