javascript - Why is localStorage not used to store static resources? -

-

This question logically follows this question:

It is clear that the popular site HTML5 application caching is not used to save static resources because it was designed.

Just & lt; Html & gt; Check for the attribute in the tag, it is not there.

Seeing it further, HTML5 local storage is not being used.

I saw in the case of a test

  • www Google.com
  • www.twitter.com
  • www.facebook .com

    Just go to console and type 

      localStorage.   
     And the console should pop up a list of keys.  
     None of these sites can save their static data to disk?  
     Why this?  
     It seems that resources like a waste of resources have not been hit for the network.  
     If you click on the reload to expand, the page will download the remaining resources again. You can also see the terms used in the URL path with Google. However for this question I use the conceptual meaning of the word.  
      
     
     
     
     It is clear that site HTML5 application caching is used to save popular static resources. Are not because it was designed.   
     The UIA misunderstood which app was designed for caching. The first paragraph of the application cache space is here:  
     
     Despite being able to continue interacting with web applications and documents, even when their network connection is unavailable ??? For example, because they are traveling outside of your ISP coverage area ???? The authors can provide a manifest that lists the files needed for the web application to work offline and that causes the user's browser to maintain a copy of files for offline use.  
         
     Therefore, app caching was designed to allow web app writers to work their apps when a network connection is not available.  
     I can not see whether Google, Twitter or Facebook can work without a useful network connection. All those users rely on having a large amount of data on their servers (in the case of Twitter and Facebookâ € ™ s, other users' data). They are naturally useless without a network connection.  
     Similarly,  is not local storage  which may be designed to process page resources (I think you are suggesting that this site is local I can store CSS, Javascript and image files in the format if I am misunderstood.)  
     
     Specify two related mechanisms, HTTP session cookies to store structured data on the client Comes similar to ...  
     The first scenario is designed for the user where the user is taking a transaction, but can take out of the same deal with different windows at the same time ... < / P> 
     The second storage system, which is spread to many windows, is designed to remain beyond the current season. Specifically, web applications want to store user's megabytes of data, such as the entire user-writer document or the user's mailbox, due to customer reasons for performance reasons ...  
      < / Blockquote> 
     To use  localhourage  for CSS, JavaScript and image files, you need to have every Javascript in that page to check for  localStorage  is needed by the page, then (in some way) to see if there was a new version of the server to check it for grabbing, then the resource was added to the domain of that page (and if it was new it was local Stored in esoys).  
     By default there are a lot of code for repeating the caching that web browsers already have. And when your Javascript is checking  local storage  and server, the page stops rendering. While the browser download is only in CSS and image files, the page can turn on rendering, while doing so.

excel vba - How to delete Solver(SOLVER.XLAM) code -

After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'

I have a UITextView and I change a word like the code at the end of UITextView.text: - (void) Replace TexttechWitWord: (NSString *) word {NSString * currentTextViewText = self.textView.text; CurrentTextViewText = [currentTextViewText stringByReplacingCharactersInRange: NSMakeRange ([self.textView.text length] - [word length], [word length]) withString: word; Self.textView.text = currentTextViewText; } Replacement work is fine, but it runs very slowly and very slowly when the textView now lengthens Is there any better way? I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job.
