  • jQuery internals: Organization of the jQuery Object

    - by sonofdelphi
    I was going through the source code of jQuery. I'm having trouble understanding the wrapping strategy for the jQuery object. (function( window, undefined ) { // Define a local copy of jQuery var jQuery = function( selector, context ) { // The jQuery object is actually just the init constructor 'enhanced' return new jQuery.fn.init( selector, context ); }, .... .... .... // Expose jQuery to the global object window.jQuery = window.$ = jQuery; })(window); Specifically, what I'm not able to understand stems from the first line. What is the outermost unnamed container function? Why is it required? Why is the container function anonymous? What is the need for the outermost '(' parantheses ?

  • How to navigate to another html page?

    - by newbie
    In my application there's a usual login page sending username and password to the server script, where it needs to be authenticated, and in case of an authentic user, the server should redirect to a page student.html. This is my code var ports = 3000; var portt = 3001; var express = require('express'); var student = require('express')(); var teacher = require('express')(); var server_s = require('http').createServer(student); var server_t = require('http').createServer(teacher); var ios = require('socket.io').listen(server_s); var iot = require('socket.io').listen(server_t); var path = require('path'); server_s.listen(ports); server_t.listen(portt); student.use(express.static(path.join(__dirname, 'public'))); student.get('/', function(req,res){ res.sendfile(__dirname + '/login.html'); }); teacher.use(express.static(path.join(__dirname, 'public'))); teacher.get('/', function(req,res){ res.sendfile(__dirname + '/mytry.html'); }); ios.sockets.on('connection', function(socket){ var username, password; socket.on('check',function(data){ username = data[0]; password = data[1]; //************* Database connection and query ************* var mysql = require('mysql'); var connection = mysql.createConnection({ host : 'localhost', user : 'user', password: '*******', database: 'my_db' }); connection.connect(); var qstring = 'SELECT s_id FROM login_student WHERE username='+username+'AND password='+password; connection.query(qstring, function(err, rows, fields) { if (err) { console.log('ERROR: ' + err); socket.emit('login_failure','DB error'); return; } console.log('The solution is: ', rows[0].solution); if (rows>0) //***** Here i want redirection to another page ****** else socket.emit('login_failure','Invalid Username or password'); }); connection.end(); }); }); iot.sockets.on('connection', function(socket){ ; }); }); Can anyone suggest what should I do?

  • Horizontally-centering an absolute position to match a relative position

    - by Chris Vandevelde
    I'm trying to make a div box, containing various elements, fixed at the top of the page once the page has been scrolled so that the box would normally be out of view, but scroll normally until that point (like the behaviour at http://perldoc.perl.org/perl.html). The conditionally-fixed part is pretty simple to implement (set the position to "fixed" once the user has scrolled past a certain point, and "static" once it's scrolled back up), but I'm having trouble with the positioning and dimensions; it screws up if I'm not specifying an absolute position (if I'm using % or "auto", rather than px, em, cm, etc.) or it, confusingly, left-aligns if the box is less than the width of the page. I can understand why, more or less, I'm just trying to fix it. My strategy right now is to have an invisible DIV hold the place of the box and use Prototype's clonePosition() function to hold its position, but it doesn't seem to work for some reason. Neither does copying the margin from one element to the other. Any ideas? Bonus points and eternal gratitude if you can come up with an idea that will adjust itself with the browser window (like auto margins) without setting an onresize event.

  • word game ???? help please

    - by lolo
    Implement the “Word Decoder” game. This game will present the player with a series of scrambled words (up to 20 words) and challenge him/her to attempt to unscramble them. Each time a new word is displayed, and a text input is provided for the user to write the unscrambled word. Once the player thinks the word has been properly decoded, he clicks on the “Check answer” button. If the player’s answer is correct, his score is increased by one. If his answer is not correct, he is notified and he is then given a different word. For example: The word “tac” is displayed. The user inputs “cat”. The answer is correct, and the user’s score is 1. The word “niol” is then displayed. The user inputs “oinl”. The answer is not correct, the user is alerted, and the score stays the same. The game then displays the next word and so on. After the last word, the final score is given to the player. can you help me please???

  • window.onbeforeunload ajax request problem with Chrome

    - by lang2
    Hello, I have a web page that handles remote control of a machine through Ajax. When user navigate away from the page, I'd like to automatically disconnect from the machine. So here is the code: window.onbeforeunload = function () { bas_disconnect_only(); } The disconnection function simply send a HTTP GET request to a PHP server side script, which does the actual work of disconnecting: function bas_disconnect_only() { var xhr = bas_send_request("req=10", function() { } ); } This works fine in FireFox. But with Chrome, the ajax request is not sent at all. There is a unacceptable workaround: adding alert to the callback function: function bas_disconnect_only() { var xhr = bas_send_request("req=10", function() { alert("You're been automatically disconnected."); } ); } After adding the alert call, the request would be sent successfully. But as you can see, it's not really a work around at all. Could somebody tell me if this is achievable with Chrome? What I'm doing looks completely legit to me. Thanks,

    - by Shashi
    I am developing Phonegap application and currently i am using InAppBrowser to display external pages. On some of the external pages I place a close button and i want to close the InAppBrowser itself. because InAppBrowser displays these pages that is why the reference of it is not accessed on itself to close it and Please do not suggest me to use ChildBrowser Plugin. window.close(); //Not Worked for me or iabRef.close(); //Also not Worked for me because iabRef is not accessible on InAppBrowser. It is created on Parent Window Some of the Android device and iOS device display a Done Button to close it. As well as the iPad also display the Done button. but in Case of Android tablet there is not any kind of button to close it. UPDATE :- Here is my full code :- var iabRef = null; function iabLoadStart(event) { } function iabLoadStop(event) { } function iabClose(event) { iabRef.removeEventListener('loadstart', iabLoadStart); iabRef.removeEventListener('loadstop', iabLoadStop); iabRef.removeEventListener('exit', iabClose); } function startInAppB() { var myURL=encodeURI('http://www.domain.com/some_path/mypage.html'); iabRef = window.open(myURL,'_blank', 'location=yes'); iabRef.addEventListener('loadstart', iabLoadStart); iabRef.addEventListener('loadstop', iabLoadStop); iabRef.addEventListener('exit', iabClose); }

  • How to make a jquery datePicker button image unclickable

    - by Farzana
    I have a jquery UI datePicker in my page. I have a text box on which the date is displayed. The code is: $("#cal").datepicker({ minDate: new Date(), defaultDate: new Date(), buttonImage: '/images/calendar.gif', constrainInput: false, closeText: 'Close', showButtonPanel: true, showButtonText: 'Choose a date', buttonImageOnly : true, showOn : 'button' }); $("#till").datepicker('setDate', today); I want to disable this on some conditions. I use the following code to disable: $("#cal").datePicker('disable'); It blacks out the text box but the image is still clickable. The problem is in IE, the date picker pop up comes up but does not close when the image button associated with the date picker is clicked. I also tried to bind a onclick function with the image to make it non-clickable. But that does not work as well. How can make the date picker image button non-clickable when the date picker is disabled. Any help would be appreciated. Thanks, Farzana

  • JSDoc3: How to document a AMD module that returns a function

    - by Jens Simon
    I'm trying to find a way to document AMD modules using JSDoc3. /** * Module description. * * @module path/to/module */ define(['jquery', 'underscore'], function (jQuery, _) { /** * @param {string} foo Foo-Description * @param {object} bar Bar-Description */ return function (foo, bar) { // insert code here }; }); Sadly none of the patterns listed on http://usejsdoc.org/howto-commonjs-modules.html work for me. How can I generate a proper documentation that lists the parameters and return value of the function exported by the module?

  • String.fromCharCode & CharacterSets

    - by jAndy
    Hi Folks, I recently tried to mirror some input within input(text) fields. Using String.fromCharCode(event.which) for instance, translates all 'standard' characters correctly. Well it translates them all to uppercase, but that you can easily catch by looking up the shift key aswell. My Problem is, it can't translate characters like dots, commas, questionmarks etc. First guess was that I have to define a character encoding set, but that does not seem to help. Maybe it'm completly off? Kind Regards --Andy

  • Simple iframe editor and oninput event.

    - by teehoo
    I'm writing a simple editor in an iframe, but having trouble registering the "oninput" event to detect when the user modifies the text field such as pasting in data etc. var txtArea = document.getElementById('txtArea'); txtArea.contentWindow.document.designMode="on"; txtArea.contentWindow.document.open(); txtArea.contentWindow.document.write("body{font-size:13px;}"+data.document+""); txtArea.contentWindow.document.close(); $([txtArea.contentWindow.document]).bind("click", updateCaretPosMouse); //fires $([txtArea.contentWindow.document]).bind("keyup", updateCaretPosKeyboard); //fires $([txtArea.contentWindow.document]).bind("input", textChanged); //doesn't fire If I create a plain old textarea element, and add the "input" event to this, then it works. Do 'input" events not work with iframes WYSIWYG editors?

  • Tag-like autocompletion and caret/cursor movement in contenteditable elements.

    - by jimeh
    I'm working on a jQuery plugin that will allow you to do @username style tags, like Facebook does in their status update input box. My problem is, that even after hours of researching and experimenting, it seems REALLY hard to simply move the caret. I've managed to inject the <a> tag with someone's name, but placing the caret after it seems like rocket science, specially if it's supposed work in all browsers. And I haven't even looked into replacing the typed @username text with the tag yet, rather than just injecting it as I'm doing right now... lol There's a ton of questions about working with contenteditable here on Stack Overflow, and I think I've read all of them, but they don't really cover properly what I need. So any more information anyone can provide would be great :)

    I have a JSON object like the following var p = { "p1": "value1", "p2": "value2", "p3": "value3" }; Now I want to loop through all p elements (p1,p2,p3...) and get their key and values. How can I do that? I can modify the Json object if necessary . My ultimate goal is to loop through some key value pairs. And if possible I want to avoid using eval.
