Understanding javascript DOM core ideas: nodeList vs HTMLElement objects

由 余生长醉 提交于 2019-12-21 22:16:36
问题 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], element1 and the HTMLElement has not? Could someone explain this to me

“Array.prototype.slice: 'this' is not a JavaScript object” error in IE8

由 故事扮演 提交于 2019-12-19 05:56:16
问题 It is my understanding that IE8 has access to the Array.prototype.slice method. Yet when I try to call it to turn a NodeList into an array, it gives me the error Array.prototype.slice: 'this' is not a JavaScript object . You can check it out here, or look at my code here: HTML <div id="test">Test</div> JavaScript var divs = document.getElementsByTagName('div'); divs = Array.prototype.slice.call(divs); console.log(divs); What's going on here? 回答1: Update: A NodeList can be treated as an array

Create node list from a single node in JavaScript

由 旧城冷巷雨未停 提交于 2019-12-18 19:40:23
问题 This is one of those it seems so simple, but I cannot come up with a good way to go about it. I have a node, maybe nodelist = document.getElementById("mydiv"); - I need to normalize this to a node list. And not an array either: an actual, bona-fide nodeList object. Not nodelist = [document.getElementById("mydiv")]; No libraries, please. 回答1: Reviving this because I recently remembered something about JavaScript . This depends on how the NodeList is being checked, but.. var singleNode =

How can I convert an Array of nodes to a static NodeList?

由 ≯℡__Kan透↙ 提交于 2019-12-17 17:56:21
问题 NOTE: Before this question is assumed a duplicate, there is a section at the bottom of this question that addresses why a few similar questions do not provide the answer I am looking for. We all know that it is easy to convert a NodeList to an Array and there are many ways to do it: [].slice.call(someNodeList) // or Array.from(someNodeList) // etc... What I am after is the reverse; how can I convert an array of nodes into a static NodeList? Why do I want to do this? Without getting too deep

What does [].forEach.call() do in JavaScript?

由 时光毁灭记忆、已成空白 提交于 2019-12-16 21:02:08
问题 I was looking at some snippets of code, and I found multiple elements calling a function over a node list with a forEach applied to an empty array. For example I have something like: [].forEach.call( document.querySelectorAll('a'), function(el) { // whatever with the current node }); but I can't understand how it works. Can anyone explain me the behaviour of the empty array in front of the forEach and how the call works? 回答1: [] is an array. This array isn't used at all. It's being put on the

Can a javascript attribute value be determined by a manual url parameter?

问题 I am trying to display data from an external .jsp file, which is set up something like this: <tag> <innertag1 id="1"> <innertag1 id="2"> </tag> <tag> <innertag2 id="3"> <innertag2 id="4"> </tag> To display only information from only one particular "innertag" tag, I'm currently using: NodeList labs = XMLInfo.getElementsByTagName("innertag1"); I'd like to be able to isolate any particular tag with ease. Theoretically, I could create many individual pages and simply change the values to

Extract column from CSV file to use as nodelist in NetworkX

由 僤鯓⒐⒋嵵緔 提交于 2019-12-11 06:03:43
问题 I have a CSV file with 2 columns: user and locations. I want to create two lists: one with only users and the other with only locations so that I can use the draw_network_nodes(nodelist=...) function in networkx to draw users and locations separately as nodes with different shapes and colors (all users will be blue boxes and all locations will be red circles). Also, there is a header in my CSV file, so I do not want the header names to be part of either lists. 回答1: Since you provided no input
