nested

问题 I'd like to created an xml document with nested elements from an object with nested objects but the xml file comes out too flat. How can I get this to iterate the objects within objects to create elements within elements. public object traverse(object pc, string xpath, XmlDocument xmldoc) { IEnumerable enumerable = pc as IEnumerable; if (enumerable != null) { foreach (object element in enumerable) { RecurseObject ro = new RecurseObject(); ro.traverse(elementArray, xpath, xmldoc); } } else {

问题 I have a page of data that can be viewed as a list or as markers on a map. It also has filtering in the sidebar. I currently have this structured as separate map and list pages but I want to merge them so that the filters remain when switching views. I have tried using ui-router but due to my markup I cannot keep the filtering within a parent state, as per my question here: How do I show multiple views in an abstract state template? My current markup is like this: <div class="main-container"

问题 I'm working with a nested state object that I have been updating with onChange functions, like so: const [someState, setSomeState] = useState({ customer: [ { name: "Bob", address: "1234 Main Street", email: "bob@mail.com", phone: [ { mobile: "555-5555", home: "555-5555" } ] } ] }); const updateSomeStatePhone = e => { e.persist(); setSomeState(prevState => { prevState.customer[0].phone[0].mobile = e.target.value; return { ...prevState }; }); }; <p>Update Mobile Number<p> <select value=

问题 I have tried to get my head around building a recursive function to handle formatting of a unknown depth multi-dimensional array to HTML and nested Divs. I thought that it should be a piece of cake, but no. Here's what I have come up with this far: function formatHtml($array) { $var = '<div>'; foreach ($array as $k => $v) { if (is_array($v['children']) && !empty($v['children'])) { formatHtml($v['children']); } else { $var .= $v['cid']; } } $var.= '</div>'; return $var; } And here's my array:

问题 got some code what is getting unexpected results: If i replace the nested class with the Myclass, then there is no problem. What do I miss? It doesn't matter if I bind text (to an other control) or bind the image. xaml code: <Window x:Class="WpfApplication1.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525"> <Window.Resources> <DataTemplate x:Key="DataTemplate_Level">

问题 I am new to XSL and in the process of picking this up from scratch to solve a problem. I have a source XML file that contains the following structure:- <root> <Header> </Header> <DetailRecord> <CustomerNumber>1</CustomerNumber> <DetailSubRecord> <Address>London</Address> </DetailSubRecord> <DetailSubRecord> <Address>Hull</Address> </DetailSubRecord> </DetailRecord> <DetailRecord> <CustomerNumber>2</CustomerNumber> <DetailSubRecord> <Address>Birmingham</Address> </DetailSubRecord>

问题 I'm new to Excel IF statements and am having trouble with what I believe is called a nested IF function . I've looked at other IF questions on here and they're too complicated for my novice brain to understand. I have a column that has numbers in it. There are about a dozen different numbers. The numbers represent a specific team. For example, 100 is team red, 101 is team yellow, 102 is team green, etc. I need to create an IF statement that will tell me what each of the teams are based on the

问题 I have a unordered list like: <ul> <li>Element one <ul> <li><a>Element two</a> <ul> <li><a>Element three</a></li> </ul> </li> </ul> </li> </ul> Now if I try to select the <a> -element of "Element two". I would do it like the following: ul ul li:first-child > a This will select also the following nested <a> element. See this fiddle: http://jsfiddle.net/38ksdpw3/ How can this be solved? 回答1: You probably need to add an identifier to the first <ul> element and then walk through the children tree
