dynamic

问题 (Duplicate?) I've tried several Stackoverflow postings related to this, but I cannot get a javaScript example to work. I'd like to avoid having to use jQuery , for the time being. I want to create the information shown by radio buttons dynamically , using javascript . In this example, I would want to write a function that displays some other values for these radio buttons 'Answer 1' and 'Answer 2'. For example, I don't actually want 'Answer 1'. Goal is for the user to click on one of the

问题 I have been tasked with modifying a page so that it accepts an uploaded file and parses the contents of that file to display it in a particular format. I have code that parses the file - but currently it reads a static file on the server and reads it as a string. Instead I want the contents of the file to populate the string after upload. What's the best way to accomplish this using PHP/JS. I would prefer not to use PHP at all if possible, but it's fine if I have to. Other options are also

问题 How can I use this: https://developers.google.com/chart/interactive/docs/roles if I populate the graph dynamically?

问题 We're developing a SaaS accounting product that uses the Loopback REST framework and allows authenticated end users to create new tables in their own database instance (MySQL or PostgreSQL). QUESTION : How can we create a new root level Looback REST endpoint in code (on the fly) to access the new table? For example if the user adds a new table named 'cars' we need to expose a new root level REST endpoint in code called '/api/cars' that uses the persisted model to provide full CRUD capability

问题 I have found many articles on dynamic pivots, selecting the data first and then running a 2nd query to do the pivot, however I have a large query that I require a dynamic pivot and am not sure how to get it working. The servers on each host can change this is why I need it to be dynamic. There is probably a very simple fix but I'm not great with SQL Server. This is the code I have so far: DECLARE @StartTime Date DECLARE @EndTime Date SET @StartTime = '2014-08-19 23:00:00' SET @EndTime = '2014

问题 I am trying to understand how decorator pattern works and how much I can "stretch" it to me needs. Following this example, I have extended classes XYZ. There exist derived classes "KLM" (from XYZ) Specifically, even though I have a decorator pattern, the derived decorator classes "KLM" have some functionality that does not show up in any of their base classes "XYZ", "D", "I" or "A". So while normally I would instantiate an object as I * inKLM = new L( new M( new K( new A ))); This would not
