prefix

问题 I am attempting to render a composite ProductCatalog view in ASP.NET MVC. This requires that I render multiple Product views per page. Each product view is a separate form. I need the form fields to have a prefix based on the id, so that I don't have duplicate IDs in the rendered document. Is there a way to define a prefix to be applied to all the form fields that are generated by the Html Extensions, or do I need to build this out manually? 回答1: Yes, you can define a prefix for the controls

问题 I wanted to know what is the pythonic function for this : I want to remove everything before the wa path. p = path.split('/') counter = 0 while True: if p[counter] == 'wa': break counter += 1 path = '/'+'/'.join(p[counter:]) For instance, I want '/book/html/wa/foo/bar/' to become '/wa/foo/bar/' . 回答1: A better answer would be to use os.path.relpath: http://docs.python.org/2/library/os.path.html#os.path.relpath >>> import os >>> full_path = '/book/html/wa/foo/bar/' >>> print os.path.relpath

问题 I use Compass 1.0 and when I do @include display-flex; or any other flex related property I get only display: -webkit-flex; display: flex; -webkit-flex-flow: row wrap; flex-flow: row wrap; etc. No -moz or -o prefixes. Any idea why? 回答1: Opera has never used the -o- prefix for Flexbox. It was introduced under the Presto engine without prefixes. It wasn't until later that support for Flexbox properties (along with a few others) that the -webkit- prefix was also supported. The Flexbox module

问题 I'm trying to compose a SOAP request to ebay FindingAPI web service by using C# XmlDocument class in the following code: XmlDocument doc = new XmlDocument(); XmlElement root = (XmlElement)doc.AppendChild(doc.CreateElement("soap", "Envelope", "http://www.w3.org/2003/05/soap-envelope")); root.SetAttribute("xmlns", "http://www.ebay.com/marketplace/search/v1/services"); XmlElement header = (XmlElement)root.AppendChild(doc.CreateElement("soap", "Header", "http://www.w3.org/2003/05/soap-envelope"))

问题 I have big set of urls and I want to implement an autocompletion. I don't like the complexity of the naive approach as it is linear with the set size: for(String url: urls) if(url.startsWith(input) {doSomething();} Now I know that in a Hash Set, the function "contains()" works in "O(1)" but there is no "containsPrefix()". Is there a simple way without using a big library like Lucene or coding it myself? I would have no problem doing it but it seems overkill for such a simple problem so I want

问题 My app uses many libraries and I'm using java.util.logging for logging. I'd like to be able to set different logging levels for each library by doing something like: org.datanucleus.*.level = WARNING com.google.apphosting.*.level = WARNING com.myapp.*.level = FINE Is is possible? 回答1: You shouldn't use "*". A sample logging.properties could be such as: handlers=java.util.logging.ConsoleHandler .level=ALL java.util.logging.ConsoleHandler.level = ALL java.util.logging.ConsoleHandler.formatter

问题 What conventions are people here following for naming of instance variables and method arguments - particularly when method arguments are used to set ivars (instance variables)? In C++ I used to use the m_ prefix for ivars a lot. In C# I followed the convention of disambiguating purely by use of this. for ivars. I've since adopted the equivalent in C++ too ( this-> ). In Objective C I've tried a few things but none have really seemed satisfactory. Unless someone suggests something really nice

问题 I am trying to run another NodeJS version with nvm but getting this error: $ nvm use v4.2.4 nvm is not compatible with the npm config "prefix" option: currently set to "/Users/z/.npm-global" Run `npm config delete prefix` or `nvm use --delete-prefix v4.2.4` to unset it. I have my prefix set on purpose to avoid sudo npm (see https://docs.npmjs.com/getting-started/fixing-npm-permissions). Is there any way I can use nvm without losing my prefix for globally installed packages? 回答1: Delete and

问题 I am able to do this with IPv4 using code snippets from various online sources. I was wondering if there was a way to do it with IPv6. Basically I just need a form that I can enter an IPv6 address and prefix (ex: address/68) and it calculates the network address, first useable address, last useable address, and broadcast address. Then just prints to screen. Not looking to store it in a database or anything yet. How would I go about doing this? Thanks to everyone in advance! 回答1: First of all:
