问题 I'm having an issue here, and after 2 hours of Googling Stackoverflow answers and testing different ideas I can't figure it out. Hopefully it's a no-brainer for someone out there. EDIT: Fixed! See solutions below. Here is my code: // Establish Table and vars mysql_query("CREATE TABLE IF NOT EXISTS pages(page varchar(255), content varchar(255))"); $page = 'Hello'; $content = 'This is the content.'; // Ive tried this: mysql_query("INSERT INTO pages SET page='$page' ON DUPLICATE KEY UPDATE

问题 This one is baking my noodle big time! I have some arrays inside an array that looks like this var lidHours = {"192611":[ ["07:00","21:30"], ["07:00","21:30"], ["07:00","21:30"], ["09:00","21:30"], ["09:00","00:00"], ["08:00","08:00"], ["",""] ] } And an array of the week days var weekDays = new Array("Mon", "Tue", "Wed", "Thur", "Fri", "Sat", "Sun"); So each array represents a day of the week. I'm outputting onto the page like this: Monday: 7:00 - 21:00 and so on... But you can see that the

问题 With my very limited knowledge of both jQuery and JS i made a small script (with the help of Nicola Peluchetti) that duplicates a tablerow when a button is clicked. This works like a charm, however, i would like to add a datepicker to it. This also works well, but just once and not on the copied fields or visa versa. It's probably because the datepicker "thinks" there is just one field. I found several sources to solve the problem, but again, with my newbie knowledge, it's just to hard. I am

问题 I have a HashMap in Java: HashMap<String, Integer> meh = new HashMap<String, Integer>();` meh.put("one", 1); meh.put("one", 1); meh.put("one", 1); meh.put("two", 1); meh.put("two", 2); meh.put("three", 3); What I need is to remove duplicating entries ("one", 1) [when both key and value duplicate]. I searched and found only 'how to remove duplicating keys/values'. Can anyone help? 回答1: There is no need to do that, HashMap takes care of that automatically. What happens when you execute that

问题 I'm posting data to a service that requires that I submit duplicate query string keys (ugly and not specified in any standards). I'm using WebClient object to build the request. I'd like to keep using it since it is used frequently elsewhere in the project. When I do this foreach(var f in formats) client.QueryString.Add("formats", f); I get a list &formats=format_1,format_2,format_3 which the service does not support. Is there a better alternative than this old-school ugliness: var

问题 My SQL query returns results with 4 columns "A", "B", "C", "D". Suppose the results are: A B C D 1 1 1 1 1 1 1 2 2 2 2 1 Is it possible to get the count of duplicate rows with columns "A", "B", "C" in each row. e.g. the expected result is: A B C D cnt 1 1 1 1 2 1 1 1 2 2 2 2 2 1 1 I tried using count(*) over. But it returns me the total number of rows returned by the query. Another information is that in example I have mentioned only 3 columns based on which I need to check the count. But my
