What is the difference between a HTMLCollection and a NodeList in DOM?

由 ╄→гoц情女王★ 提交于 2019-12-08 15:09:38
问题 I tried my Google-fu but I can't seem to find any good answer to that question. Please help. EDIT: Ok so I found this blog post. So they come from different DOM levels, but besides that it doesn't say much... 回答1: As you said, NodeList is defined in DOM-Level-3-Core and HTMLCollection in DOM-Level-2-HTML. Their interfaces are : interface HTMLCollection { readonly attribute unsigned long length; Node item(in unsigned long index); Node namedItem(in DOMString name); }; interface NodeList { Node

问题 This question already has answers here : Why does jQuery or a DOM method such as getElementById not find the element? (8 answers) Closed 5 years ago . I have a NodeList object that is created by var buttons = document.getElementsByName("signupButton"); console.log(buttons); prints [item: function] 0: button.btn.btn-warning.btn-lg 1: button.btn.btn-warning.btn-lg 2: button.btn.btn-warning.btn-lg length: 3 __proto__: NodeList But buttons.length is printing 0. What is going on here? 回答1: This is

Understanding javascript DOM core ideas: nodeList vs HTMLElement objects

由 不羁岁月 提交于 2019-12-04 16:13:41
I have been working towards understanding the DOM very thoroughly. At the moment i'm making my way trough traversing the DOM tree and i seem to be finding some inconsistencies. On a nodeList i can use an index to iterate trough the list On a HTMLElement i can't use an index See this fiddle for an example: http://jsfiddle.net/AmhVk/4/ So the question is, why is it that the nodeList has an indexable list like element[0], element 1 and the HTMLElement has not? Could someone explain this to me very thoroughly? Thx... <ul id="jow"> <li><a href="">Item</a></li> <li><a href="">Item</a></li> <li class

Is it possible to append an element to a JavaScript nodeList?

由 谁说我不能喝 提交于 2019-12-04 03:01:55
I'm generating content dynamically, so I'm often ending up with documentFragments which I'm querying using querySelectorAll or querySelector returning a nodeList of elements inside my documentFragment. From time to time I would like to add an item to a list, but I can't find anything online on whether this is even possible. I tried it like this: document.querySelectorAll(".translate").item(length+1) = document.createElement("div"); and this: document.querySelectorAll(".translate").shift(document.createElement("div")); But both don't work (as expected) Question: Is it possible to manually add

Convert NodeList to array

由 喜欢而已 提交于 2019-12-04 00:54:11
问题 I'm having a hard time converting a NodeList to an array in IE 8. The following works perfectly in Chrome, but in IE 8 toArray() is not recognized as valid: NodeList.prototype.toArray = function() { var a = []; for (var i = 0, len = this.length; i < len; i++) { a[i] = this[i]; } return a; } document.all.tags("div").toArray(); I tried adding a prototype function to an array just to check my sanity and it works correctly. That makes me think IE 8 doesn't actually return a NodeList ? Here's a

Filter or map nodelists in ES6

由 落爺英雄遲暮 提交于 2019-12-03 06:12:00
问题 What is the most efficient way to filter or map a nodelist in ES6? Based on my readings, I would use one of the following options: [...nodelist].filter or Array.from(nodelist).filter Which one would you recommend? And are there better ways, for example without involving arrays? 回答1: [...nodelist] will make an array of out of an object if the object is iterable. Array.from(nodelist) will make an array out of an object if the object is iterable or if the object is array-like (has .length and

Why do nodelists contain extra undefined items that are not reflected in its length property?

由 别说谁变了你拦得住时间么 提交于 2019-12-01 11:00:05
Background: I came across a very strange phenomenon while working with a node list. I wanted to use getElementsByClassName or something similar and then sort it. I decided one way would be to iterate through the nodelist and push each item to an array and sort the array. (This did work by the way but not as expected). I tried using the for (var i in nodeList) to iterate through, but it kept throwing an exception on the last few items, which were undefined. the weird part is I could instead use for (var i = 0; i < nodeList.length; i++) to iterate through. I just tested it again and on a
