JavaFx实现按钮防抖功能

//注意Button是javafx包的
fun Button.isFastClick(): Boolean {
    val lastClickTime = userData as Long?
    val currentTime = System.currentTimeMillis()

    userData = currentTime
    //这里我设置为1s内多次点击无效，可以根据需要调整
    if (lastClickTime != null && currentTime - lastClickTime <= 1000) {
        return true
    }
    return false
}

button{
    action {
        //不是快速点击才进入点击逻辑
        if (!isFastClick()) {
            println("hello")
        }
    }
}

fun Button.isFastClick(time:Long): Boolean {
    val lastClickTime = userData as Long?
    val currentTime = System.currentTimeMillis()

    userData = currentTime
    if (lastClickTime != null && currentTime - lastClickTime <= time) {
        return true
    }
    return false
}


fun Button.setActionHank(time:Long = 1000,op: () -> Unit) {
    action {
        if (!isFastClick(time)) {
            op()
        }
    }
}

button("测试") {
    //这里不用action了
    setActionHank{
        println("111")
    }
}

class ButtonUtils {
    public static boolean isFastClick(Button button) {
        Object userData = button.getUserData();

        long currentTime = System.currentTimeMillis();
        button.setUserData(currentTime);
        if (userData instanceof Long) {
            Long lastClickTime = (Long) userData;
            return currentTime - lastClickTime <= 1000;
        }
        return false;
    }
}
