oncancel 特性为 GlobalEventHandlers 混合 EventHandler 为处理 cancel events sent to a <dialog> 元素。

cancel event fires when the user indicates a wish to dismiss a <dialog> . This event handler prevents the event from bubbling, so any parent handlers are not notified of the event.

句法

target.oncancel = functionRef;

值

functionRef is a function name or a 函数表达式 . The function receives an 事件 object as its sole argument.

Only one oncancel handler can be assigned to an object at a time. You may prefer to use the EventTarget.addEventListener() method instead, since it's more flexible.
