问题 I want to show the Visits for the current day on a homepage. That page is tracked with Piwik.

A few days ago I wrote a new plugin for Piwik which displays total

问题 I'm trying to create a Data class whose objects each hold a unique ID. I want the 1st object's ID to be 1, the 2nd to be 2, etc. I must use a static int , but all the objects have the same ID, not 1, 2, 3... This is the Data class: class Data { private: static int ID; public: Data(){ ID++; } }; How can I do it so the first one ID would be 1, the second would be 2, etc..? 回答1: This: class Data { private: static int ID; const int currentID; public: Data() : currentID(ID++){ } }; Besides a

问题 This question already has an answer here : Create a “counter” on matlab from 0:limit-1. The length of counter is not determined in the program (1 answer) Closed 6 years ago . Q- Create a "counter" from 0:limit-1 (for example if you choose 3 it will display 0,1,2). The length of counter is not determined in the program and it should be determined when it is being run and the inputs can differ from each other 回答1: not really sure what you mean...but for i = 0:limit-1 disp(i) end will display 0

问题 I'm new to this type of programming (management figures programming is programming... ugh), apologies in advance if my question seems convoluted or basic. I'm creating a Windows Form App in Visual Studio 2015. I have it communicating and sharing with our SQL Server perfectly for every function but one. I'd like to place a "live" counter on the form, that updates a value every 3(or something) seconds. The counter's job would be to keep track of inventory being shipped out of our warehouse

问题 I'm trying to make a dropdown menu using nested <ul> , every <li> displaying a number generated with CSS Counters. Sub-menus are hidden with display:none when not hovered. My problem is that counters are not incremented when an element has display set to none . Do you know a CSS property to prevent this? If I replace display: none by visibility: hidden , it's working but I'm not sure if it's nice to use this for my menu, are there any traps? 回答1: You can mimick the display: none (hidden)

问题 I've been trying to find a function which increments a counter using words. I know its possible using numbers with suffixes (i.e. 1st, 2nd, 3rd and so on). Here is a snippet of the code i've got: function addOrdinalNumberSuffix($num) { if (!in_array(($num % 100),array(11,12,13))){ switch ($num % 10) { // Handle 1st, 2nd, 3rd case 1: return $num.'st'; case 2: return $num.'nd'; case 3: return $num.'rd'; } } return $num.'th'; } Code Source But is there a way to replicate this with words (i.e

问题 Looking for a script that I can ideally enter a starting number and a start date, which then continues to increment based on a rate I set e.g. 1 per second . The script would ideally calculate what number it should be on based on the difference between the current time and start time. It's meant to look like it's showing a live count. Ideally, something like the counter on http://sendgrid.com/ Has anyone got a link or plugin or solution they can share? If the numbers can be replaced with

问题 Below is the copy of my code. Basically, I need to create a program that calculates pay based on "paycodes" eg the worker's position. I've created my switch statement and everything works except for the very beginning when I'm entering the first paycode. I enter the first paycode, it goes to the next line, leaving it blank. I put in another number, and it runs that number and the previous number the way it is supposed to. Then, after that everything works fine. I'm sure it's a simple solution

问题 I need to make a simple countdown timer from 5 to zero, with the buttons to START and STOP the counter. The only thing that I don't know is that why won't my counter stop. The code is presented below: function clock() { var myTimer = setInterval(myClock, 1000); var c = 5; function myClock() { document.getElementById("demo").innerHTML = --c; if (c == 0) { clearInterval(myTimer); alert("Reached zero"); } } } <p id="demo">5</p> <button onclick="clock()">Start counter</button> <button onclick=
