Array#each takes an array and applies the given block over all items. It doesn’t affect the array or creates a new object. It is just a way of looping over items. Also it returns self. arr=[1,2,3,4] arr.each {|x| puts x*2} Prints 2,4,6,8 and returns [1,2,3,4] no matter what Array#collect is same as Array#map and it … Read more
Because when you use a return statement inside an each loop, a “non-false” value will act as a continue, whereas false will act as a break. You will need to return false from the each function. Something like this: function findXX(word) { var toReturn; $.each(someArray, function(i) { $(‘body’).append(‘-> ‘+i+'<br />’); if(someArray[i] == word) { toReturn … Read more
First of all, the @each function is not from Compass, but from Sass. To answer your question, this cannot be done with an each loop, but it is easy to convert this into a @for loop, which can do this: @for $i from 1 through length($refcolors) { $c: nth($refcolors, $i); // … do something fancy … Read more
Description: .each is an iterator that is used to iterate over only jQuery objects collection while jQuery.each ($.each) is a general function for iterating over JavaScript objects and arrays. Examples 1) Using $.each() function var myArray = [10,20,30]; $.each( myArray, function(index, value) { console.log(‘element at index ‘ + index + ‘ is ‘ + value); … Read more
I added this as a comment but now that I have read it correctly and answered my own question this would probably work: function positionCards() { var $cards = $(‘#gameboard .card’); var time = 500; $cards.each(function() { setTimeout( function(){ addPositioningClass($(this)); }, time) time += 500; }); }
For next examples assumed that you use C++11. Example with ranged-based for loops: for (auto &attack : m_attack) // access by reference to avoid copying { if (attack.m_num == input) { attack.makeDamage(); } } You should use const auto &attack depending on the behavior of makeDamage(). You can use std::for_each from standard library + lambdas: … Read more
In jQuery just use: $(‘#tblOne > tbody > tr’).each(function() {…code…}); Using the children selector (>) you will walk over all the children (and not all descendents), example with three rows: $(‘table > tbody > tr’).each(function(index, tr) { console.log(index); console.log(tr); }); Result: 0 <tr> 1 <tr> 2 <tr> In VanillaJS you can use document.querySelectorAll() and walk … Read more
For your first two example cases, you could use key() and current() to assign the values you need. $ar = $o->me; // reset isn’t necessary, since you just created the array $typ = key($ar); $val = current($ar); $out = array(‘me’ => array(), ‘mytype’ => 2, ‘_php_class’ => null); $expected = [key($out), current($out)]; In those cases, … Read more
users.each_with_index do |u, index| # some code if index == users.size – 1 # code for the last user end end
$(‘#list option’).each(function(index){ //do stuff console.log(index); }); logs the index 🙂 a more detailed example is below. function run_each() { var $results = $(“.results”); $results.empty(); $results.append(“==================== START 1st each ====================”); console.log(“==================== START 1st each ====================”); $(‘#my_select option’).each(function(index, value) { $results.append(“<br>”); // log the index $results.append(“index: ” + index); $results.append(“<br>”); console.log(“index: ” + index); // logs the … Read more
