jquery - javascript dom insertion. Performance vs Leak? -

-

I'm wondering what is the right way to put complex elements

So far, ( With jQuery) I used to first build my own element and to finish it once. I thought it was the most efficient, because Dome Access performance is fantastic.

But with the original JS, I have read that to avoid memory leaks, each new dome node should be inserted into the dome immediately after its creation.

Our intranet says:

Note the DOM Entry Order DOM Entry Order: No root element attached to the original element is attached to the DOM itself Please.

var root = document.createElement ("DIV"); Var children = document.createElement ("DIV"); // It is wrong root.appendChild (child); Document.body.appendChild (Route); // This is the right document. Don.appendChild (Route); Root.appendChild (child);

I found this page online that basically explain the same thing (under the cross-page leak section):

This means that Performance and leakage-prevention?

Should the new DOM elements be created and manipulated in the form of a string before being inserted? How are the JS libraries solving this? What is a miracle solution in the document?

Your quote is inspired by the article written by almost one member about the IE team, special Sections related to "DOM Insertion Order Leak Model" are eligible for a two-digit note:

  1. This article was written in 2005 specifically to address leaks issues in IE6 Had IE 7 been not released;
  2. This is only concerned with IE; There is no suggestion that any other browser is suffering from the same problem. According to the ("top management" under memory management improvements), IE 7 contains improvements to prevent such leaks for lifetime, in the browser window, and in IE 8 Hope has improved in the hope of ending the need to worry about the matter.

    The question you need to ask is: How important is IE6 for you? At the end of the day, DOM insertion order should never be anything to worry, but if (for example) you are working on an intranet app that will be used on IE6 for some time, then you Keep in mind the points in the 2005 article, if you have a luxury to know that IE6 is hardly a blip on your app's radar, do not worry about it.

    Oh, and note that adding everything to parents will provide better performance before adding parents to the page: if a new baby is added to each child Rather than replacing and replying, the browser can refill and repeat again when everything can come in a systematic part.

I am getting an error with php in order to format mysql_query () in php to format this string What is the right way? SELECT SELECT SELECT (*) Agents @AgentCount; User_Agent_English, User_Angent_Oursal, US.___Gent_Aginal, COUNT (User_Agent_Percade) ACC, COUNT (*) / (AgentCount) Percentage by agents user_agent_preser order DEC limit limit 50; In PHP, how am i setting $ query $ query = "SELECT count (*) agents @ agentcount; SELECT user_agent_parsed, User_agent_original , COUNT (user_agent_parsed) ascount, COUNT (*) / (@AgentCount) as a percentage by user_agent_parced by URI date DESC limit 50 "; This exact query will work properly if I put it in MySQL directly through a command line session. Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne...

url rewriting - How to implement the returnurl like SO in PHP? -

-
This URL should work even after the rewrite. Is this possible? Otherwise, I can only hardcoded everything If you are trying to create a login system with redirection You need to use the HTTP_REFERER header to find out where the user came from so that you can send it back there. The best way to do this is to use something like this in your login form: // - Login php & Lt; Input type = "password" name = "password" /> & Lt; Input type = "hidden" name = "returnrelale" value = "& lt ;? php echo $ redirectURL ;? & gt;" / & Gt; & Lt; / Form & gt; Please note that some ISP, browser or proxy will delete the referrer header, so you can not rely on each user to work fully. If you use a statement, to check whether the header exists or not, you can send those users back to the homepage or whatever. Edit If you are looking to use $ _SERVER ['REQUEST_URI'], if you are running Apache It sho...

Which Python client library should I use for CouchdB? -

-
I am starting to experiment with CouchDB because it looks like we have the right solution to certain problems That all the work will be on a new project, which does not have any legacy dependency, which the client library will suggest you use, and why? If we overlap any of the OS. Freeband is available only in the collection of its ports, but asks to use the library's project website. None of those people are Ubuntu, which is only with ships, since those two OSAs are not common in libraries, I am probably installing something from source (and hopefully if I have time, then Ubuntu and FreeBSD People pack the package). For those interests, I want to use CouchDB as a convenient intermediate storage space for data passed between different services - think of a message bus system, but less formalities with. For example, we have daemons that download and pars the web page, then send an interesting bit to other daemons for further processing. Many of them are ill-defined until the...
