Javascript: attaching OOP methods to events and the 'this' keyword -

-

I'm new to OOP Javascript and I'm having trouble with keywords in this .

What I am trying to achieve: I have many dom objects and not only want to pose a common event to them, but a global container (to increase runtime performance) Keep some data about

So what I do is basically this: 

  function class hasdodops something () {/ * This keeps node ID for processing in the INIT. Nodes = new array (); / * Process node data for faster access * / this.nodeData = new array (); This.sthAddNodes = function (/ * id * /) {/ * Add node ID for local variant (this.nodeData) * /} function init () {/ * collects data from all nodes which was added before And stores it in .nodeData * / / * Here, surprisingly, it references' window element * / addEvent (window, 'scroll', this.scroll); } Function Scroll () {/ * Does the user do stuff while scrolling the page * / / * 'This' also reference the window element here * /} addEvent (window, 'load', this, etc.); }

Later, in the document body, I could add it: 

  var Ctds = new classmatos (some);

Further, add the DOM elements as follows: 

  Ctds.addNodes (ID);

No more implementation code will be required.

Question: How to Access to JS and Scroll methods And not in the window element class instance .

This is not through the keyword , I know, but still I have not come anywhere.

PS

  • addEvent is an extremely basic task to engage events, it is just IE / Fx friendly and nothing is.
  • Code I writing is already functional, but in procedural form, I wanted to do it OOP.
  • As a short sub-question, I get some kind of effect, the guest / setter methods in JavaScript are discouraged. Is it okay if I use them?

    • One thing I know is neither Init And the scroll is a method on this example.

    So you do not need to add init and this.init to the load code only: 

      addEvent (Window, 'load', init); // no. "Required

    and similarly: 

      addEvent (window, 'scroll', scroll);

    If you decide to go to class (for example, this.scroll and this.init etc), you can save the This is a reference to and it is passed to an addEvent : 

      var = an anonymous function passed to this; This.init = function ( ) {AddEvent (window, 'scroll', function () {self.scroll ()}}} this. Scroll = function () {/ * ... *}} AddEvent (window, 'load', function N () {self.init ()});

    It is called A.

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...

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...
