问题 How to create dynamic nested menu from json object? I started using Angular Material Design today for the first time and I'm trying to create nested menus using material design. The documentation is pretty straight forward for static stuff. But I need to create dynamic nested menu from json object and I can't find a simple solution to this anywhere. It just needs to be one level deep. json object(not set in stone): my_menu = { 'main1': ['sub1', 'sub2'], 'main2': ['sub1', 'sub2'], } which

问题 EDIT: I changed the example code after the first answer because I came up with a simple version that begs the same questions. I am currently learning Common Lisp's scoping properties. After I thought I had a solid understanding I decided to code up some examples that I could predict the outcome of, but apparently I was wrong. I have three question, each one relating to an example below: Example 1: (defmethod fun1 (x) (print x) (fun2)) (defmethod fun2 () (print x)) (fun1 5) Output: 5 *** -

问题 I am trying to loop through a table that has a column for "customers" and "dollar amount" . If my loop finds a customer called "greg" or "henry" I want to add his "dollar amount" to an array of an unknown size. Can someone please help me? 回答1: If by unknown size, you mean that number of elements is unknown, you could use a dynamic array. Dim aArray() As Single ' or whatever data type you wish to use ReDim aArray(1 To 1) As Single If strFirstName = "henry" Then aArray(UBound(aArray)) = 123.45

问题 My C program is crashing and I am too new to figure it out. It's very simple so far and I imagine the code is enough to figure out what is going wrong. I am simply trying to read a file line by line. I will double the memory of a structure once I am out of memory. If this is not enough information, I will give whatever else you need. Thank you very much for any help, as I have been stuck for hours now. /* John Maynard 1000916794 7/15/2013 HW-06 */ #include <stdio.h> #include <stdlib.h>

问题 We are creating a dynamic web application where only some parts of the web page will get loaded/unloaded/reloaded through JQuery AJAX. But we are concerned what will happen if user runs our application for a long time (some hours) without completely refreshing the web page. For example, we have a game with modules Map, Shop, Fight. The page also has some modules which are loaded at the beginning (like header with stats and a chat). But all the navigation and changes occur mostly in the center

问题 Ninite.com seems to be doing it currently. I'm wondering how. While it's possible for them to have every combination of app pre-generated, it seems unlikely/hacky. [EDIT] Is compiling a Windows executable using this method resource-intensive? Can it be done ~100k times a day without exorbitant cost? I'm asking because Ninite announced that they're going paid-only... can it be costing them that much? [EDIT2] The downloads aren't huge, it's just a small hundred KB web-based downloader+installer
