问题 Is an Element an instance of a Node in HTML? I presume Attributes are also Nodes and that "the Elements" is the set of Nodes that can be defined using the angle-bracket syntax? 回答1: Yes it is a Node , according to the MDN documentation for HTMLElement : Inherits properties from its parents Node , and its own parent, EventTarget , and implements those of ParentNode , ChildNode , NonDocumentTypeChildNode , and Animatable . If that's a bit hard to find in text, MDN also provides an "Inheritance

问题 Please, I am searching for a solution to not display the root node and connecting lines to it. I have already tried to append multiple append("svg:svg") and populate those with root.children[...] nodes, but I don't like that because it looks inefficient to me. <!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html;charset=utf-8"/> <link type="text/css" rel="stylesheet" href="style.css"/> <script type="text/javascript" src="d3/d3.js"></script> <script type="text

Is nodeIndex a valid DOM element property in IE?

由 亡梦爱人 提交于 2019-12-11 10:38:58
问题 I came across some javascript at work today that used jQuery to fetch two elements. It then used elem.nodeIndex to determine the position in the elements parent for each element. Nothing is setting this property anywhere and I do now see a reference to it in the msdn, mdc, or anywhere else. I stepped through this javascript in FireFox with FireBug and tested the code in chrome and opera. I am sure nothing was trying to set this property. However, I can't find any information on this nodeIndex

NetworkX: add edges to graph from node attributes

由 纵然是瞬间 提交于 2019-12-11 10:27:14
问题 My nodes have a list of attibutes that is seperated by commas, i wanted networkx to compare them and if they match, create an edge between the nodes. That is as for as i got, but it's not working, any ideas on how to improve my approach? for node in G.nodes(): while len(G.node[n]['attr']) = (G.node[n+1]['attr']): # compare attributes? valid_target_found = False while not valid_target_found: target = random.randint(0,N-1) # pick a random node if (not target in G.node[n]['attr']) and len(G.node

What are “marker for NULL pointers” in binary tree?

由 廉价感情. 提交于 2019-12-11 10:05:29
问题 I was going through this and this post about binary search tree implementation. I saw that a binary search tree is represented as (for example) : 1 5 7 10 40 50 I was trying to learn about the serialization or de-serialization of the same here. The blog post is making me crazy with those -1 s which they're calling markers for NULL pointers . And they're representing the tree as: 20 8 4 -1 -1 12 10 -1 -1 14 -1 -1 -1 Confusion What are those -1 s? My final goal is to store and read a binary

Spring Data Neo4j 4.0.0: Can't Create Relationship Between Nodes with the Same Label

由 主宰稳场 提交于 2019-12-11 08:32:31
问题 I'm using Spring Data Neo4j 4.0.0 with Neo4j 2.2.1 and I'm trying to create a relationship between two nodes with the exact same labels. So, I have a NodeEntity class and I have a variable inside with the same Type as the class itself, and annotate it as Relationship. But, when I save the object to the database using the save() method of the repository object, the relationship can't be created. Thank you in advance and your suggestion would be really appreciated! EDIT Here is the node entity
