Sorting list of elements in JQuery

梦想的初衷 提交于 2019-11-29 04:28:13
I have a list of elements that I get using JQuery. var $self = $(this); var $fields = $('.identifier-controls', $self); This list is the list of elements that need to be manipulated in some way when the control renders. Each element in the list of $fields contains a data attribute called "data-order". This attribute tells me what order I should arrange the elements with in the control (ah requirements). The order does not have to be in direct linear order (meaning that the first control can have an attribute value of 10 and the next one 15 and the next one 17 etc. They just need to appear in

Remove Specific Array Element, Equal to String - Swift

若如初见. 提交于 2019-11-28 19:30:04
问题 Is there no easy way to remove a specific element from an array, if it is equal to a given string? The workarounds are to find the index of the element of the array you wish to remove, and then removeAtIndex , or to create a new array where you append all elements that are not equal to the given string. But is there no quicker way? 回答1: You can use filter() to filter your array as follow var strings = ["Hello","Playground","World"] strings = strings.filter{$0 != "Hello"} print(strings) // "

Number of elements in a javascript object

妖精的绣舞 提交于 2019-11-28 16:02:16
Is there a way to get (from somewhere) the number of elements in a javascript object?? (i.e. constant-time complexity). I cant find a property or method that retrieve that information. So far I can only think of doing an iteration through the whole collection, but that's linear time. It's strange there is no direct access to the size of the object, dont you think. EDIT: I'm talking about the Object object (not objects in general): var obj = new Object ; Christoph Although JS implementations might keep track of such a value internally, there's no standard way to get it. In the past, Mozilla's

How to set DOM element as the first child?

☆樱花仙子☆ 提交于 2019-11-28 15:49:57
I have element E and I'm appending some elements to it. All of a sudden, I find out that the next element should be the first child of E. What's the trick, how to do it? Method unshift doesn't work because E is an object, not array. Long way would be to iterate trough E's children and to move'em key++, but I'm sure that there is a prettier way. var eElement; // some E DOM instance var newFirstElement; //element which should be first in E eElement.insertBefore(newFirstElement, eElement.firstChild); pery mimon 2017 version You can use targetElement.insertAdjacentElement('afterbegin',

I have a select box that gets cloned. I want to remove the user's previous selection from each cloned select box. Here is the method that does the clone() : function addselect(s){ $('#product_categories > .category_block:last').after( $('#product_categories > .category_block:last').clone() ); set_add_delete_links(); return false; } function set_add_delete_links(){ $('.remove_cat').show(); $('.add_cat').hide(); $('.add_cat:last').show(); $("#product_categories > .category_block:only-child > .remove_cat").hide(); } function removeselect(s){ $(s).parent().remove(); set_add_delete_links(); return

jQuery get the text of all elements in a page

浪尽此生 提交于 2019-11-28 08:53:58
问题 I want to get the text of all elements. I am using this code here: $('*').filter(function() { if(($(this).text().lenght>0)&&($(this).text().lenght<100)) { return true; } else { return false; } }).each(function() { console.log($(this).text()); }); I have try to show only short text because .text() sometime returns html code but it is not working at all. 回答1: It's much more simple: $('body').text() gives you the whole text on the page. If you need to iterate over all the text nodes, see here:

combined multiple classes into one css rule

心已入冬 提交于 2019-11-28 04:21:58
问题 I'm trying to do some buckets here and generally I would do 1 class element at a time. That seems silly since classes can share attributes. HTML <div id = "outerBuckets"> <div class = "bucket1"> <div class ="bucketIcon"> <p></p> </div> </div> <div class = "bucket2"> <div class ="bucketIcon"> <p></p> </div> </div> <div class = "bucket3"> <div class ="bucketIcon"> <p></p> </div> </div> <div class = "bucket4"> <div class ="bucketIcon"> <p></p> </div> </div> <div class = "bucket5"> <div class =

How to stop knockout.js bindings evaluating on child elements

橙三吉。 提交于 2019-11-27 14:39:09
问题 Using knockout, when you call ko.applyBinding(viewModel, "divId") it does a recursive binding down through the children of the element you bound to ("divId"). I would like to stop this evaluation at a child node. Is there a way to do this? the reason why... I would like to bind the entire page to a navigation view model, this will handle basic layout and ...smile... navigation. On the various pages I would like to bind certain regions to different view models that are not properties of the
