nested

问题 I have been struggling for a while with the following problem: I would like to get some data before the view shows, (resolve). But some of the data is dependend on the result of another promise. It goes like this: I get the job id (index) from the $stateParams and look up the data in my Service. Once it is completed, from this result (the job), I can look up the settings and floors (each from a different service), both return a promise. What I've came up so far jobinfo: function(Jobs, Floor,

问题 I am currently trying to write a regular expression in PHP that allows me to match a specific pattern containing itself indefinetely nested. I know that per default regular expressions are not capable of doing that, but PHP's Recursive Patterns (http://php.net/manual/de/regexp.reference.recursive.php) should make it possible. I have nested structures like this: <a=5> <a=3> Foo <b>Bar</b> </a> Baz </a> Now I want to match the content of the outmost tag. In order to correctly match up the first

问题 Say, I have the following list raw <- list(list(1:2, 2:3, 3:4), list(4:5, 5:6, 6:7), list(7:8, 8:9, 9:10)) I would like to find the mean of the corresponding entries of the out-most list. The expected output would be something like [[1]] [1] 4 5 [[2]] [1] 5 6 [[3]] [1] 6 7 This is because the mean of 1:2 , 4:5 , and 7:8 would be 4:5 . I have been experimenting with stuff like lapply(raw, function(x) lapply(x, mean)) , but apparently it doesn't return the desired output. 回答1: This is pretty

问题 I'm currently working on a program that requires a nested structure. Though, I am not sure I understand it. I'd like your help with this if anyone could. First week learning C++ so don't give me a hard time :P I'm supposed create a Person structure containing two string members, first and last. Create an Address structure containing four string members, street, city, state, and zipcode. And also create a nested structure, Employee, that consists of three members. A Person member named name,

问题 Consider a document in Elasticsearch like this: { "id": 1, "Comment": "Comment text", "Reply": [{ "id": 2, "Comment": "Nested comment text", }, { "id": 3, "Comment": "Another nested comment text", }] } I want to search for id == 2 without knowing whether it is in the firsts level of the document or in the second. Is this possible? Please also keep in mind that the nested level can be anything (unknown at development time). If this is possible, what's the query to return this document by

问题 I'm developing an application form. The components tree of it: Application Form Fieldset Field The Application component has configuration props for the Form component called formSettings so that it passes them so: <application-form v-bind="formSettings"/> Next, I need to synchronize FormData with the Fieldsets. It's important that in my case all values to sync have an object type! To achieve it, firstly, I've decided to make a deep clone of the fieldsets configuration prop to an inner

问题 I have the following code: def flat_list(array): d=[] for i in array: if not isinstance(i, list): d.append(i) else: flat_list(i) return d When I call flat_list([1, [2, 2, 2], 4]) , I expect it to return unpacked list ([1, 2, 2, 2, 4]). Instead it returns ([1, 4]). Although, if I try (print i) instead of (d.append(i)) , it returns unpacked i. I read an article about recursion, it says return needs to be after base condition. How do I use kindda ( return d.append(i) )? 回答1: you call your

问题 I am writing a videoplayer with tkinter/python , so basically I have a GUI that can play a video. Now, I would like to implement a stop button, meaning that I would have a mainloop() for the GUI, and another nested mainloop() to play/stop the video and return to the GUI startup window. Here, it is said: Event loops can be nested; it's ok to call mainloop from within an event handler. However, I do not understand how to implement this nesting. Can someone please provide me with a simple

问题 I want to create a structure which consists of quite some elements, the basic layout of it goes like that: <UniformGrid> <Border> // This one is 9x <UniformGrid> // This one is 9x, each as a child of the border <Border> // This one is again 9x, so at total 9x9 = 81 of these <TextBox> // Same as above, each one as a child of the Border ..... </TextBox> </Border> </UniformGrid> </UniformGrid> So, having that many number of controls, I was wondering what solution is more elegant and proper: 1:
