counter

I have a new business, where I just hired someone to work for me, I am trying to make it easy for her to track her time, so I created a clock in button, that creates a record in a database, I have it pop up a small window, that she can click to clockout when she is done working. I want it to show her on that popup window a counter that will show how long she has been working, so I want to create a javascript or jQuery that will start at a certain time and count from there. She is on the East Coast, our company is in the Central Timezone, so 1 hour behind her. How can I get a javascript to

和闭包一样，练代码 struct Counter { count: u32, } impl Counter { fn new() -> Counter { Counter {count: 0 } } } impl Iterator for Counter { type Item = u32; fn next(&mut self) -> Option<Self::Item> { self.count += 1; if self.count < 6 { Some(self.count) } else { None } } } #[test] fn using_other_iterator_trait_methods() { let sum: u32 = Counter::new().zip(Counter::new().skip(1)) .map(|(a, b)| a * b) .filter(|x| x % 3 == 0) .sum(); assert_eq!(18, sum); } 来源： https://www.cnblogs.com/aguncn/p/11438455.html

I want to increment a field value safely using php and mysql. What type of table/field must I use? Is there a minimum version of MySQL I must use? What's the sql code for this, safe transaction for MySQL? By what type of "table" I assume you mean storage engine. Anything that supports mutations (i.e. not "archive" or "black hole") Any numeric field will do (tinyint, int, float, etc). That said, there's no special PHP code, just the SQL for incrementing the desired field: UPDATE table SET field = field + 1 WHERE [...] If you want a transaction, then pack the above query into a transaction. As

I used Counter on a list to compute this variable: final = Counter(event_container) print final gives: Counter({'fb_view_listing': 76, 'fb_homescreen': 63, 'rt_view_listing': 50, 'rt_home_start_app': 46, 'fb_view_wishlist': 39, 'fb_view_product': 37, 'fb_search': 29, 'rt_view_product': 23, 'fb_view_cart': 22, 'rt_search': 12, 'rt_view_cart': 12, 'add_to_cart': 2, 'create_campaign': 1, 'fb_connect': 1, 'sale': 1, 'guest_sale': 1, 'remove_from_cart': 1, 'rt_transaction_confirmation': 1, 'login': 1}) Now I want to convert final into a Pandas DataFrame , but when I'm doing: final_df = pd.DataFrame

I would like to include a flip counter on my site, similar to what Apple was using for their 1 billion app countdown . Can anyone get their JavaScript to work standalone? If anyone can provide working code, that would be great. Steve Harrison They're using a combination of CSS and JavaScript. The flip animation is powered by a CSS Sprite -like technique. First of all, they have a very tall image called filmstrip.png that contains every flip "state" for each number (0 to 9; have a look at a scaled-down detail and you'll see what I mean). Then, in the HTML, each digit is made up of three nested

Just thought I would share the answer to the problem I had. I was looking for a way to count all the likes and comments from each of the photos in my photo album on Facebook. My photo album had thousands of likes and comments spread out over hundreds of photos so there was no way it could be done by hand. I couldn't find an existing way to do it automatically so here is my solution. After lots of experimenting with the Facebook Graph API trying to figure out how to get the info from Facebook this is the final working URL: https://graph.facebook.com/albumID/photos?fields=id,likes.summary(true)

I am trying to figure out the fastest way to access data stored in a junction object. The example below is analagous to my problem, but with a different context, because the actual dataset I am dealing with is somewhat unintuitive in its relationships. We have 3 classes: User , Product , and Rating . User has a many-to-many relationship to Product with Rating as the junction/'through' class. The Rating object stores the answers to several questions which are integer ratings on a scale of 1-5 (Example questions: How is the quality of the Product , how is the value of the Product , how user
