You need to capture the return value from setInterval( … ) into a variable as that is the reference to the timer: var interval; var count = 0; function onloadFunctions() { countUp(); interval = setInterval(countUp, 200); } /* … code … */ function countUp() { document.getElementById(“here”).innerHTML = count; count++; if(count === 10) { clearInterval(interval); countUp(); … Read more
The ‘\n’ character in the format string of scanf(“%d\n”, &paycode) matches any number of whitespace characters (space, tab, newline etc. – characters for which the isspace function declared in ctype.h yields true) in the input given. Therefore, the scanf call will read and discard any number of whitespace characters till it encounters a non-whitespace character … Read more
The simplest method would be cookie checking. A better way would be to create an SQL database and assign the IP address as the primary key. Then whenever a user visits, you would insert that IP into the database. Create a function included on all pages that checks for $_SESSION[‘logged’] which you can assign whatever … Read more
Initialize the Counter once, let the keys be artists, and augment a key (artist) each time through the loop: c = Counter() for d in entries: arts = d[‘artist’] c[arts] += 1 print(c.most_common(10)) When arts is a string, then c = Counter(arts) counts the characters in arts: In [522]: collections.Counter(‘Led Zepplin’) Out[522]: Counter({‘e’: 2, ‘p’: … Read more
First, you are not increasing the counter. Changing COUNTER=$((COUNTER)) into COUNTER=$((COUNTER + 1)) or COUNTER=$[COUNTER + 1] will increase it. Second, it’s trickier to back-propagate subshell variables to the callee as you surmise. Variables in a subshell are not available outside the subshell. These are variables local to the child process. One way to solve … Read more
This would be simpler: return Interlocked.Increment(ref COUNTER); MSDN Interlocked.Increment
Your claim is absolutely false depends on the input. If you have a diverse set of keys, and hits the except block often, the performance is not good. If the try block is dominant the try/except idiom can be performant on smaller lists. Here is a benchmark showing several ways to do the same thing: … Read more
The .inViewport() plugin triggers a callback on every scroll event. It’s by design. (Helps to keep the source of a plugin in code! 😉 ) On the “plugin page” you can see how to use it: $(“selector”).inViewport(function(px) { console.log( px ); // `px` represents the amount of visible height if(px){ // do this if element … Read more
Counters are a kind of multiset. From the Counter() documentation: Several mathematical operations are provided for combining Counter objects to produce multisets (counters that have counts greater than zero). Addition and subtraction combine counters by adding or subtracting the counts of corresponding elements. Intersection and union return the minimum and maximum of corresponding counts. Each … Read more
Use var instead of int for your clicks variable generation and onClick instead of click as your function name: var clicks = 0; function onClick() { clicks += 1; document.getElementById(“clicks”).innerHTML = clicks; }; <button type=”button” onClick=”onClick()”>Click me</button> <p>Clicks: <a id=”clicks”>0</a></p> In JavaScript variables are declared with the var keyword. There are no tags like int, … Read more
