onbeforeunload - Strategies for preserving form data ( on tab/browser close ) -

-

I have a work management application that sometimes users close their browsers / tabs and the information they type They get away because they accidentally close a browser / tab, resulting in the text they enter (and can enter some half-hour text).

So I have to provide a solution, I have some ideas, but wanted to input the best to go together, or listen to me if you have a better solution.

Option 1:

  • window.optimize or possibly window.First to close event a confirmation ( ) Demonstrates the first test and whether there is a text in the logging area and it is not empty. If this is not empty, call window.confirm () and ask if the user wants to close the tab / window without saving the log.

My concern with option # 1 is that it can be intruder to the user.

Option 2:

  • At the same event, do not open any confirmation (), but rather save the text effectively. The task logging area in a cookie can then : Provide a button that attempts to restore any saved work information from a cookie on a single page, so that the button will help to parse cookies and get the information.

If the user is doing anything to remove it before submitting There is enough profit for them, so they should not infiltrate to ask if they want to do something that is apparently stupid.

In addition to this, SO has used a confirmation dialog when navigating, and here is the most (some) users

It is very easy.

This is the easiest to use, and probably will help users more.

If someone writes a long piece of text, then without turning the browser off, collecting it, they can be more pleased to solve the problem there, and instead of going out the next morning, they It did not ...

MySql variables and php -

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...
