javascript - Keep text selection when focus changes -

-

I have a generic textbox, and there is a lightbox with a text input.

I select the user in the text box, even if the user is focused on the text input of the lightbox.

  • Select the text in the normal text box
  • Toggle lightbox
  • Turn focus on Lightbox input

    • Step 3 However, the text of the user is discarded. How can this be prevented? For example see the Google Docs link entry lightbox.

    Update

    OK, so Google uses an iframe for Docs blank page segment, Anything that they are handling (like the excuse of hateful HTML): 

      // test.html & lt; Html & gt; & Lt; Body & gt; & Lt; H1 onclic = 'lightbox ();' & Gt; This is the main part & lt; / H1> & Lt; Iframe src = 'frame.html' & gt; & Lt; / Iframe & gt; & Lt; Div id = 'lightbox' style = 'display: none; Status: fixed; Top: 0; Left: 0; Height: 100%; Width: 100%; Opacity: 0.8; Background color: black; '& Gt; & Lt; Input type = 'text' name = 'url' / & gt; & Lt; / Div & gt; & Lt; Script type = 'text / javascript' & gt; Function lightbox () {document.getElementById ('lightbox'). Style.display = 'block'; } & Lt; / Script & gt; & Lt; / Body & gt; & Lt; / Html & gt; // frame.html & lt; P & gt; This is my iframe & lt; / P & gt;

    The focus in the input in the lightbox is if the text selection in the iframe is free so if some text is selected 'This is my iframe' then the lightbox is toggled and The cursor placed in the input, the iframe's text selection remains intact without any javascript.

    I'm trying to suggest Nicolai

    From: You have to preserve the selection and restore it to focus. Must do: 

      $ ("dialog"). Focus (function () {// save selection}}. Blur (function () {// set text selection});

    Selecting Selection (From): 

      $ Fn.selectRange = function (start, end) {return.Each (function () {if (This.SetSelectionRange) {this.focus (); this.setSelectionRange (start, end);} and if (this.createTextRange) { Var range = this.createTextRange (); range.collapse (true); range.moveEnd ('character', end); category.movest ('character', start); category.select ();}}); }; $ ('# ELEM') selectRange (3,5).

    Getting the Selection:

    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...
