Either use return, as the closure basically is a method that is called with each element as parameter like def myObj = [“Hello”, “World!”, “How”, “Are”, “You”] myList.each{ myObj-> if(myObj==null){ return } println(“My Object is ” + myObj) } Or switch your pattern to def myObj = [“Hello”, “World!”, “How”, “Are”, “You”] myList.each{ myObj-> if(myObj!=null){ … Read more
$.each() works for objects and arrays both: var data = { “programs”: [ { “name”:”zonealarm”, “price”:”500″ }, { “name”:”kaspersky”, “price”:”200″ } ] }; $.each(data.programs, function (i) { $.each(data.programs[i], function (key, val) { alert(key + val); }); }); …and since you will get the current array element as second argument: $.each(data.programs, function (i, currProgram) { $.each(currProgram, … Read more
var total = $(‘ul li’).length; $(‘ul li’).each(function(index) { if (index === total – 1) { // this is the last one } });
There are a lot of answers here. And it’s old, but this is for anyone coming here via google. In jQuery each function return false; is like break. just return; is like continue These will emulate the behavior of break and continue.
Thymeleaf th:each allows you to declare an iteration status variable <span th:each=”task,iter : ${foo.tasks}”> Then in the loop you can refer to iter.index and iter.size. See Tutorial: Using Thymeleaf – 6.2 Keeping iteration status.
Your thisdoesn’t refer to the element in the step callback, instead you want to keep a reference to it at the beginning of your function (wrapped in $thisin my example): $(‘.Count’).each(function () { var $this = $(this); jQuery({ Counter: 0 }).animate({ Counter: $this.text() }, { duration: 1000, easing: ‘swing’, step: function () { $this.text(Math.ceil(this.Counter)); } … Read more
One solution you could use is to assign a more generalized class to any div you want the click event handler bound to. For example: HTML: <body> <div id=”dog” class=”selected” data-selected=”false”>dog</div> <div id=”cat” class=”selected” data-selected=”true”>cat</div> <div id=”mouse” class=”selected” data-selected=”false”>mouse</div> <div class=”dog”><img/></div> <div class=”cat”><img/></div> <div class=”mouse”><img/></div> </body> JS: $( “.selected” ).each(function(index) { $(this).on(“click”, function(){ // For … Read more
Use parentheses not brackets: (1..10).each{println it} [1..10] is a list of length 1 containing a single range.
each passes into your function index and element. Check index against the length of the set and you’re good to go: var set = $(‘.requiredText’); var length = set.length; set.each(function(index, element) { thisVal = $(this).val(); if(parseInt(thisVal) !== 0) { console.log(‘Valid Field: ‘ + thisVal); if (index === (length – 1)) { console.log(‘Last field, submit form … Read more
Try this, replacing .myClassName with the actual name of the class (but keep the period at the beginning). $(‘.myClassName’).each(function() { alert( this.id ); }); So if the class is “test”, you’d do $(‘.test’).each(func…. This is the specific form of .each() that iterates over a jQuery object. The form you were using iterates over any type … Read more
