Interface ThrottleOptions

If debounceMode is true (at begin), the callback is executed at the beginning of the delay period. If debounceMode is false (at end), the callback is executed at the end of the delay period.

如果 debounceMode 为 true（前缘模式），回调函数在延迟期开始时执行。 如果 debounceMode 为 false（后缘模式），回调函数在延迟期结束时执行。

Optional, defaults to false. If noLeading is false, the first throttled-function call will execute callback immediately. If noLeading is true, the first the callback execution will be skipped. It should be noted that callback will never executed if both noLeading = true and noTrailing = true.

可选，默认为false。如果noLeading为false，第一次节流函数调用将立即执行回调。 如果noLeading为true，第一次回调执行将被跳过。 需要注意的是，如果noLeading = true且noTrailing = true，回调将永远不会被执行。

Optional, defaults to false. If noTrailing is true, callback will only execute every delay milliseconds while the throttled-function is being called. If noTrailing is false or unspecified, callback will be executed one final time after the last throttled-function call. (After the throttled-function has not been called for delay milliseconds, the internal counter is reset)

可选，默认为false。如果noTrailing为true，回调函数仅在节流函数被调用时每delay毫秒执行一次。 如果noTrailing为false或未指定，回调函数将在最后一次节流函数调用后额外执行一次。 （当节流函数在delay毫秒内未被调用时，内部计数器将被重置）
