javascript - Jquery help me analyze what happened: mouseover/mouseout ok but not hover/unhover -

-

I am working on some code where I trigger the code on hover / unhover . Then I decided to trigger the same code on Focus / Blur . Generally with hover / unhuror , I can always type as no commas format. But this time when I was trying to add Focus / Blur then I had to use the bind and with the second part was to use this.bind Such as: 

  $ .fn.gogogo = function (msg) {$ (this) .bind ("focus hover", function () {$ ("# screen") .html (msg) ) .show ();}); $ (This) .bind ("blur unhover", function () {$ ("# screen") .html (""). Hide ();}); }

The problem was that whatever I did, I did not take hover / nonover / . I had to return to mouseover / mouseout Code hover / unhover vs mouseover / mouseout 

  $ In addition to Fn.gogogo = function (code), the code is the same {$ (This) .bind ("mouseover focus", function () {$ ("# screen") .html (msg) .show ();}); $ (This) .bind ("mouseout blurred", function () {$ ("# screen") .html (""). Hide ();}); }

I thought that the hover / unvover only mouseover / mountout was uniquely. How behaviors differ: Hover / NonHower breaks my code, while mouseover / mouseout is okay?

Thank you.

hover .

Hover method is a feature method that combines event handlers into mousecenter and mouseover events.

If you open the source of jQuery, you will see that the hover method is defined as such: 

  hover: function (fnOver, FnOut) {Return to this Musicor (Funovers). Mouseleave (fnOut); },

You should bind the mousecenter and mouseleave instead of the event.

Edit : The difference between mousecenter and mouseover is that the mousecenter (And mouseleave ) is not bubble. This means that if you bring the mouse to any element, you will get a mouseover event (which is probably not what it is You want), while you only see Mousecenter event if the mouse has entered the element itself, for example, see

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...

php - Laravel - Overriding a resource route into a different route filter group -

-
Does Laravel's routing work as expected? What I think, if I want to override a route, then I just have to give the expected route before each other. I have something like this: root :: group (array ('first' = & gt; 'defaultLoads' =); function () {root :: post 'Newsletter', 'newsletter controller @ store'); root: group (array ('(newsletter', 'newsletter controller');}}); That if I post this route, only http://domain.com/newsletter should run only the default loads route filter. However, when I call php Runs artisan routes , I get this: | | POST newsletter | newsletter.store | newslettercontroller@ store | default loads | login | | though it reads the route correctly (PHP artisan loads which The correct path is to the right place) but the file of the resource path even if it is not in the filter group, the path is affected. Then my question: How does it work Laravel? If so, do I post this -> Newsle...
