increment

问题 I'm creating an "animated letter incrementer" that takes any given word and increments each letter of that word starting from A. Example: Word = Dog D - Increments from A to D [A, B, C, D] O - Increments from A to O [A, B, C, D, E, F, G, H, I, J, K, L, M, N, O] G - Increments from A to G [A, B, C, D, E, F, G] The effect I'd like to achieve is similar to this jQuery animated number counter, except I'll be incrementing letters instead of counting numbers. Also, each letter of the word should

问题 How can I generate a sequence of numbers like 1 2 4 8 11 12 14 18 ... (plus 10 every 4 numbers) with the following additional requirements: using only one loop output should stop when a value in the sequence is greater than a specified input Examples $input = 24; 1 2 4 8 11 12 14 18 21 22 24 $input = 20; 1 2 4 8 11 12 14 18 Here's what I tried so far: <?php // sample user input $input = 20; $number = 1; $counter = 0; $array = array(); //conditions while ($counter < 4) { $counter++; array_push

问题 I have this nested dictionary : playlist = {u'user1': {u'Roads': 1.0, u'Pyramid Song': 1.0, u'Go It Alone': 1.0}} and I'm trying to increment its float values by 1.0 : user = playlist.keys()[0] counts = playlist[user].values() for c in counts: c += 1.0 I've come this far. now, how do I update the dictionary with the incremented value ? 回答1: To update float values in the nested dictionary with varying levels of nesting, you need to write a recursive function to walk through the data structure,

问题 I would like to calculate visibility mean every five minutes. I try to use for loop, but it is not successful. Can someone help to fix it?

问题 I was reading the re-introduction to JavaScript on the MDN website and came across this example in the Array section: for (var i = 0, item; item = a[i++];){ // Do something with item } Where "a[]" is an array being looped over. I am confused about the value that "item" will have in its first iteration. As i=0 and item is at first undefined, then when it is assigned the value of a[i++] wouldn't the iteration start from i=1, which would mean that the iteration would start from the second

问题 Hi I have a very simple PHP function which when runs always returns the value of 1. I need to increment the value of the variable $board to 1,2,3,4,5,6 and so on. Cannot catch the error here ? function poste() { $board++; echo $board; global $sourcedir; require_once($sourcedir . '/Subs-Post.php'); $msgoptions = array( 'id' => 0, 'body' => 'Welcome', 'subject' => 'Welcome To The Boards', ); $topicoptions = array( 'id' => 0, 'board' => $board, 'poll' => null, 'lock_mode' => 0, 'sticky_mode' =>

问题 This question already has answers here : cannot use + when try to add number (4 answers) Closed 4 years ago . var counter = 0; var userAdd = prompt("How many would you like to add?"); counter += userAdd; console.log(counter); New to javascript. I am trying to get the counter to increment up by the amount that the userAdd variable specifies. When I run this code all I get from the console.log() is, for example: If userAdd is '1' each time: 01 011 0111 ...etc. instead of: 1 2 3 Whats the

问题 I had questions about incremental and decremental operators.I couldn't understand why java gave these outputs. x = 5; y = 10; System.out.println(z = y *= x++); // output is 50 x = 2; y = 3; z = 4; System.out.println("Result = "+ z + y++ * x); // output is Result = 46 x = 5; System.out.println( x++*x); // output is 30 x = 5; System.out.println( x*x++); // output is 25 For example, in 2nd println function y is multiplicated without increasing 1 and in 3rd function x is multiplicated with x+1.

问题 I need to write a code with javascript which increase the given number and sum it with a random range numbers and finally displays it. This has to be saved, because the next day, this should increment current result, using the same "sum with random range of numbers". for instance: Given number: 135 Random range: 5 to 20 So: Current day=135+random range, then keep it for next 24 hours. Next day=Current day+random range, then keep it for next 24 hours.... but I don't know how to do it, would

问题 I have the following code which is supposed to increment a field value by 1 in a prepared PHP mysql statement: function db_OP_doVote($pdo, $postid, $votetype) { $prepStatement = $pdo->prepare( "UPDATE content_posts SET `:votetype` = `:votetype` + 1 WHERE `id` = :id" ); $prepStatement->execute(array(':votetype' => $votetype, ':id' => $postid)); echo "Success"; } This however, does nothing. No error is thrown back about incorrect SQL syntax and the script runs to completion, but my field does
