javascript - jQuery Key Events with a Search Box -

-

I am working on an automatic advice plugin with jQuery, and I would like to add a keypress event so that the user down arrow Able and up In addition, if they enter, it will add value to the input.

This looks like my HTML: 

   & Lt; Label = "search" & gt; & Lt; / Labels & gt; & Lt; Div id = "myInputResults" class = "results" style = "display: block;" & Gt; & Lt; Ul & gt; & Lt; Li & gt; & Lt; A & gt; Div class = "recommended class" & gt; Suggestion # 1 & lt; / Div & gt; & Lt; / A & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A & gt; Div class = "suggest class" & gt; Suggestion # 2 & lt; / Div & gt; & Lt; / A & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A & gt; Div class = "suggest class" & gt; Suggestion # 3 & lt; / Div & gt; & Lt; / A & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A & gt; Div class = "recommended class" & gt; Suggestion # 4 & lt; / Div & gt; & Lt; / A & gt; & Lt; / Li & gt; & Lt; / Ul & gt; & Lt; / Div & gt;

So far, I have something like this: 

  $ ("# myInput"). Key (function (e) {var code = (e.keycode? E.keycode: e.which); if (code == 40) {// if user "key down" // I "first & lieutenant;

By this point, I am not sure whether to use Users can scroll, down, and press 'Enter' to select an item for proper reason.

Any suggestions and support on this will be greatly appreciated! Thank you. / P>

< V class = "post-text" itemprop = "text">

Adding on Psytronic's code, it should also cover the "Enter" keycode ... 

  $ (function ( ) {$ ("# MyInput") .keyp (function (e) {var code = (e.keyCode? E. Kikode: E.H.H.); if (code == 40) {if ($ (" Li.hovered "). Length == 0) {$ (" # myInputResults li "). Eq (0) .addClass (" hovered ");} and {$ (" ("(" ") "removeClass" ("hovered" Next (). AddClass ("hovered");}} if (code == 13) {if ($ ("li.hovered") .length & gt;) {$ ("# myInput"). Val ($ ("Li.hovered"). Eq (0) .find ("div.suggClass"). Eq (0) .text ()); }}}}}}};

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...
