> jQuery Child Selector without a parent allowed?

由 落爺英雄遲暮 提交于 2019-12-11 07:25:45
问题 Quick question, is a jQuery child selector without a parent ever valid? If so, how would you use it? Example of the jQuery child selector: $('ul > li') Example of jQuery child selector without parent: $('> li') The second example above doesn't work. However I can't remember if I saw it in the past before or I've seen something advance like: $('ul').not('>li') Doesn't really work either (but doesn't pop up an error message, so it's just ignored?) So my question is would you EVER use a child

C++ - How to call creator class/object

由 ぃ、小莉子 提交于 2019-12-11 06:25:41
问题 I need to call properties and functions of an object from a different class. The idea is passing 'this' as a parameter to the other class constructor. E.g.: instance = ClassName(this); And then do: ParentClass parentInstance; ClassName::ClassName(MainApp _instance){ parentInstance = _instance; } However, my compiler says that ParentClass does not name a type. Ideas? Also, should I use a pointer to save memory? How? Thanks in advance. UPDATE: Ok, sorry for the delay. Here it goes the actual

Is it possible to navigate to the parent node of a matched node during XSLT processing?

由 拈花ヽ惹草 提交于 2019-12-11 06:13:58
问题 I'm working with an OpenXML document, processing the main document part with some XSLT. I've selected a set of nodes via <xsl:template match="w:sdt"> </xsl:template> In most cases, I simply need to replace that matched node with something else, and that works fine. BUT, in some cases, I need to replace not the w:sdt node that matched, but the closest w:p ancestor node (ie the first paragraph node that contains the sdt node). The trick is that the condition used to decide one or the other is

XPath: Recursive Ancestor Search

问题 With my current node selected I wish to find an element <name> [./name] and return the text content. If an element <name> does not exist in the currently selected node I wish to check the parent element [./parent::name] and so on recursively up to the root, returning the value of the nearest parent where the element exists. Can it be done with XPath? 回答1: (Edit: I misinterpreted the question the first time) I propose to use ancestor-or-self::name[1] This finds all name elements, starting with

问题 Say I have a Father class to be inherited by Children classes, later I want to add more stuff into the Father class without modifying the original Father class, please teach me how could I do it. Let me clarify my question. Any valuables and methods in Father will automatically accessible to all the Children classes, right?
