  • calling a method from an event handler

    - by Ayoub
    I have this code i am working on but every time i call init method I keep getting an error this.addElement is not a function is it because i can't call methods from event handlers ? function editor () { this.init = function () { $("#area").bind('click' , this.click_event ); } this.addElement = function () { console.log("adding element"); } this.click_event = function(event) { this.addElement(); console.log("click event in x : "+event.data); } }

  • node.js callback getting unexpected value for variable

    - by defrex
    I have a for loop, and inside it a variable is assigned with var. Also inside the loop a method is called which requires a callback. Inside the callback function I'm using the variable from the loop. I would expect that it's value, inside the callback function, would be the same as it was outside the callback during that iteration of the loop. However, it always seems to be the value from the last iteration of the loop. Am I misunderstanding scope in JavaScript, or is there something else wrong? The program in question here is a node.js app that will monitor a working directory for changes and restart the server when it finds one. I'll include all of the code for the curious, but the important bit is the parse_file_list function. var posix = require('posix'); var sys = require('sys'); var server; var child_js_file = process.ARGV[2]; var current_dir = __filename.split('/'); current_dir = current_dir.slice(0, current_dir.length-1).join('/'); var start_server = function(){ server = process.createChildProcess('node', [child_js_file]); server.addListener("output", function(data){sys.puts(data);}); }; var restart_server = function(){ sys.puts('change discovered, restarting server'); server.close(); start_server(); }; var parse_file_list = function(dir, files){ for (var i=0;i<files.length;i++){ var file = dir+'/'+files[i]; sys.puts('file assigned: '+file); posix.stat(file).addCallback(function(stats){ sys.puts('stats returned: '+file); if (stats.isDirectory()) posix.readdir(file).addCallback(function(files){ parse_file_list(file, files); }); else if (stats.isFile()) process.watchFile(file, restart_server); }); } }; posix.readdir(current_dir).addCallback(function(files){ parse_file_list(current_dir, files); }); start_server(); The output from this is: file assigned: /home/defrex/code/node/ejs.js file assigned: /home/defrex/code/node/templates file assigned: /home/defrex/code/node/web file assigned: /home/defrex/code/node/server.js file assigned: /home/defrex/code/node/settings.js file assigned: /home/defrex/code/node/apps file assigned: /home/defrex/code/node/dev_server.js file assigned: /home/defrex/code/node/main_urls.js stats returned: /home/defrex/code/node/main_urls.js stats returned: /home/defrex/code/node/main_urls.js stats returned: /home/defrex/code/node/main_urls.js stats returned: /home/defrex/code/node/main_urls.js stats returned: /home/defrex/code/node/main_urls.js stats returned: /home/defrex/code/node/main_urls.js stats returned: /home/defrex/code/node/main_urls.js stats returned: /home/defrex/code/node/main_urls.js For those from the future: node.devserver.js

    - by quantum62
    i wanna insert specification of members that enter in textboxs of form in the database .i do this operation with jquery ajax when i call webmetod with static value the operation do successfully.for example this code is ok. $.ajax({ type: "POST", url:"MethodInvokeWithJQuery.aspx/executeinsert", data: '{ "username": "user1", "name":"john","family":"michael","password":"123456","email": "[email protected]", "tel": "123456", "codemeli": "123" }', contentType: "application/json; charset=utf-8", dataType: "json", async: true, cache: false, success: function (msg) { $('#myDiv2').text(msg.d); }, error: function (x, e) { alert("The call to the server side failed. " + x.responseText); } } ); but when i wanna use of values that enter in textboxes dynamically error occur.whats problem?i try this two code <script type="text/javascript"> $(document).ready( function () { $("#Button1").click( function () { var username, family, name, email, tel, codemeli, password; username = $('#<%=TextBox1.ClientID%>').val(); name = $('#<%=TextBox2.ClientID%>').val(); family = $('#<%=TextBox3.ClientID%>').val(); password = $('#<%=TextBox4.ClientID%>').val(); email = $('#<%=TextBox5.ClientID%>').val(); tel = $('#<%=TextBox6.ClientID%>').val(); codemeli = $('#<%=TextBox7.ClientID%>').val(); $.ajax( { type: "POST", url: "WebApplication20.aspx/executeinsert", data: "{'username':'username','name':name, 'family':family,'password':password, 'email':email,'tel':tel, 'codemeli':codemeli}", contentType: "application/json;charset=utf-8", dataType: "json", async: true, cache: false, success: function(msg) { alert(msg); }, error: function (x, e) { alert("The call to the server side failed.

  • ajaxSubmit options success & error functions aren't fired

    - by Thommy Tomka
    jQuery 1.7.2 jQuery Validate 1.1.0 jQuery Form 3.18 Wordpress 3.4.2 I am trying to code a contact/ mail form in above environment/ with above jQuery libs. Now I am having a problem with the jQuery Form JS: I have taken the original code from the developers page for ajaxSubmit and only altered the target option to an ID which exists in my HTML source and replaced $ with jQuery in function showRequest. The problem is, that the function namend after success: does not fire. I tried the same with error: and again nothing fired. Only complete: did and the function I placed there alerted the responseText from the receiving script. Does anyone has an idea whats going wrong? Thanks in advance! Thomas jQuery(document).ready(function() { var options = { target: '#mail-status', // target element(s) to be updated with server response beforeSubmit: showRequest, // pre-submit callback success: showResponse, // post-submit callback // other available options: //url: url // override for form's 'action' attribute //type: type // 'get' or 'post', override for form's 'method' attribute //dataType: null // 'xml', 'script', or 'json' (expected server response type) //clearForm: true // clear all form fields after successful submit //resetForm: true // reset the form after successful submit // $.ajax options can be used here too, for example: //timeout: 3000 }; jQuery("#mailform").validate( { submitHandler: function(form) { jQuery(form).ajaxSubmit(options); }, errorPlacement: function(error, element) { }, rules: { author: { minlength: 2, required: true }, email: { required: true, email: true }, comment: { minlength: 2, required: true } }, highlight: function(element) { jQuery(element).addClass("e"); jQuery(element.form).find("label[for=" + element.id + "]").addClass("e"); }, unhighlight: function(element) { jQuery(element).removeClass("e"); jQuery(element.form).find("label[for=" + element.id + "]").removeClass("e"); } }); }); // pre-submit callback function showRequest(formData, jqForm, options) { // formData is an array; here we use $.param to convert it to a string to display it // but the form plugin does this for you automatically when it submits the data var queryString = jQuery.param(formData); // jqForm is a jQuery object encapsulating the form element. To access the // DOM element for the form do this: // var formElement = jqForm[0]; alert('About to submit: \n\n' + queryString); // here we could return false to prevent the form from being submitted; // returning anything other than false will allow the form submit to continue return true; } // post-submit callback function showResponse(responseText, statusText, xhr, $form) { // for normal html responses, the first argument to the success callback // is the XMLHttpRequest object's responseText property // if the ajaxSubmit method was passed an Options Object with the dataType // property set to 'xml' then the first argument to the success callback // is the XMLHttpRequest object's responseXML property // if the ajaxSubmit method was passed an Options Object with the dataType // property set to 'json' then the first argument to the success callback // is the json data object returned by the server alert('status: ' + statusText + '\n\nresponseText: \n' + responseText + '\n\nThe output div should have already been updated with the responseText.'); }

  • Does this incorporate JavaScript closures?

    - by alex
    In trying to learn JavaScript closures, I've confused myself a bit. From what I've gathered over the web, a closure is... Declaring a function within another function, and that inner function has access to its parent function's variables, even after that parent function has returned. Here is a small sample of script from a recent project. It allows text in a div to be scrolled up and down by buttons. var pageScroll = (function() { var $page, $next, $prev, canScroll = true, textHeight, scrollHeight; var init = function() { $page = $('#secondary-page'); // reset text $page.scrollTop(0); textHeight = $page.outerHeight(); scrollHeight = $page.attr('scrollHeight'); if (textHeight === scrollHeight) { // not enough text to scroll return false; }; $page.after('<div id="page-controls"><button id="page-prev">prev</button><button id="page-next">next</button></div>'); $next = $('#page-next'); $prev = $('#page-prev'); $prev.hide(); $next.click(scrollDown); $prev.click(scrollUp); }; var scrollDown = function() { if ( ! canScroll) return; canScroll = false; var scrollTop = $page.scrollTop(); $prev.fadeIn(500); if (scrollTop == textHeight) { // can we scroll any lower? $next.fadeOut(500); } $page.animate({ scrollTop: '+=' + textHeight + 'px'}, 500, function() { canScroll = true; }); }; var scrollUp = function() { $next.fadeIn(500); $prev.fadeOut(500); $page.animate({ scrollTop: 0}, 500); }; $(document).ready(init); }()); Does this example use closures? I know it has functions within functions, but is there a case where the outer variables being preserved is being used? Am I using them without knowing it? Thanks Update Would this make a closure if I placed this beneath the $(document).ready(init); statement? return { scrollDown: scrollDown }; Could it then be, if I wanted to make the text scroll down from anywhere else in JavaScript, I could do pageScroll.scrollDown(); I'm going to have a play around on http://www.jsbin.com and report back

    I'm just programming a little function that toggles a content by fading it in and out. this.advancedSearch = function(fieldset, triggerBtn){ fieldset.hide() triggerBtn.click(function(){ fieldset.toggle(function(){ $(this).stop(false, true).fadeIn(300) }, function(){ $(this).stop(false, true).fadeIn(300) }) }) } if just I use toggle() it works, but when i insert the two functions nothing happens and no error is thrown. Is there something i have done wrong?

  • Javascript scope problem with object and setTimeout

    - by Shabbyrobe
    I'm trying to make a jQuery plugin that executes a method on a timer. I'd like it to work on multiple elements on a page independently. I've reached a point where the timer executes for each element, but the method called in the setTimeout seems to only know about the last instance of the plugin. I know I'm doing something fundamentally stupid here, but I'm danged if I know what. I know stuff like this has been asked 8 million times on here before, but I've not managed to find an answer that relates to my specific problem. Here's a script that demonstrates the structure of what I'm doing. <html> <head> <script type="text/javascript" src="assets/jquery.min.js"></script> <script type="text/javascript"> var crap = 0; (function($) { jQuery.fn.pants = function(options) { var trousers = { id: null, current: 0, waitTimeMs: 1000, begin: function() { var d = new Date(); this.id = crap++; console.log(this.id); // do a bunch of stuff window.setTimeout(function(self) {return function() {self.next();}}(this), this.waitTimeMs); }, next: function() { this.current ++; console.log(this.id); window.setTimeout(function(self) {return function() {self.next();}}(this), this.waitTimeMs); }, }; options = options || {}; $.extend(trousers, options); this.each(function(index, element) { trousers.begin(); }); return this; }; } )(jQuery); jQuery(document).ready(function() { jQuery("div.wahey").pants(); }); </script> </head> <body> <div class="wahey"></div> <div class="wahey"></div> </body> </html> The output I get is this: 0 1 1 1 1 1 The output I expect to get is this: 0 1 0 1 0 1

  • What is a good generic sibling control Javascript communication strategy?

    - by James
    I'm building a webpage that is composed of several controls, and trying to come up with an effective somewhat generic client side sibling control communication model. One of the controls is the menu control. Whenever an item is clicked in here I wanted to expose a custom client side event that other controls can subscribe to, so that I can achieve a loosely coupled sibling control communication model. To that end I've created a simple Javascript event collection class (code below) that acts as like a hub for control event registration and event subscription. This code certainly gets the job done, but my question is is there a better more elegant way to do this in terms of best practices or tools, or is this just a fools errand? /// Event collection object - acts as the hub for control communication. function ClientEventCollection() { this.ClientEvents = {}; this.RegisterEvent = _RegisterEvent; this.AttachToEvent = _AttachToEvent; this.FireEvent = _FireEvent; function _RegisterEvent(eventKey) { if (!this.ClientEvents[eventKey]) this.ClientEvents[eventKey] = []; } function _AttachToEvent(eventKey, handlerFunc) { if (this.ClientEvents[eventKey]) this.ClientEvents[eventKey][this.ClientEvents[eventKey].length] = handlerFunc; } function _FireEvent(eventKey, triggerId, contextData ) { if (this.ClientEvents[eventKey]) { for (var i = 0; i < this.ClientEvents[eventKey].length; i++) { var fn = this.ClientEvents[eventKey][i]; if (fn) fn(triggerId, contextData); } } } } // load new collection instance. var myClientEvents = new bsdClientEventCollection(); // register events specific to the control that owns it, this will be emitted by each respective control. myClientEvents.RegisterEvent("menu-item-clicked"); Here is the part where this code above is consumed by source and subscriber controls. // menu control $(document).ready(function() { $(".menu > a").click( function(event) { //event.preventDefault(); myClientEvents.FireEvent("menu-item-clicked", $(this).attr("id"), null); }); }); <div style="float: left;" class="menu"> <a id="1" href="#">Menu Item1</a><br /> <a id="2" href="#">Menu Item2</a><br /> <a id="3" href="#">Menu Item3</a><br /> <a id="4" href="#">Menu Item4</a><br /> </div> // event subscriber control $(document).ready(function() { myClientEvents.AttachToEvent("menu-item-clicked", menuItemChanged); myClientEvents.AttachToEvent("menu-item-clicked", menuItemChanged2); myClientEvents.AttachToEvent("menu-item-clicked", menuItemChanged3); }); function menuItemChanged(id, contextData) { alert('menuItemChanged ' + id); } function menuItemChanged2(id, contextData) { alert('menuItemChanged2 ' + id); } function menuItemChanged3(id, contextData) { alert('menuItemChanged3 ' + id); }

  • How to write my own global lock / unlock functions for PostgreSQL

    - by rafalmag
    I have postgresql (in perlu) function getTravelTime(integer, timestamp), which tries to select data for specified ID and timestamp. If there are no data or if data is old, it downloads them from external server (downloading time ~300ms). Multiple process use this database and this function. There is an error when two process do not find data and download them and try to do an insert to travel_time table (id and timestamp pair have to be unique). I thought about locks. Locking whole table would block all processes and allow only one to proceed. I need to lock only on id and timestamp. pg_advisory_lock seems to lock only in "current session". But my processes uses their own sessions. I tried to write my own lock/unlock functions. Am I doing it right? I use active waiting, how can I omit this? Maybe there is a way to use pg_advisory_lock() as global lock? My code: CREATE TABLE travel_time_locks ( id_key integer NOT NULL, time_key timestamp without time zone NOT NULL, UNIQUE (id_key, time_key) ); ------------ -- Function: mylock(integer, timestamp) DROP FUNCTION IF EXISTS mylock(integer, timestamp) CASCADE; -- Usage: SELECT mylock(1, '2010-03-28T19:45'); -- function tries to do a global lock similar to pg_advisory_lock(key, key) CREATE OR REPLACE FUNCTION mylock(id_input integer, time_input timestamp) RETURNS void AS $BODY$ DECLARE rows int; BEGIN LOOP BEGIN -- active waiting here !!!! :( INSERT INTO travel_time_locks (id_key, time_key) VALUES (id_input, time_input); EXCEPTION WHEN unique_violation THEN CONTINUE; END; EXIT; END LOOP; END; $BODY$ LANGUAGE 'plpgsql' VOLATILE COST 1; ------------ -- Function: myunlock(integer, timestamp) DROP FUNCTION IF EXISTS myunlock(integer, timestamp) CASCADE; -- Usage: SELECT myunlock(1, '2010-03-28T19:45'); -- function tries to do a global unlock similar to pg_advisory_unlock(key, key) CREATE OR REPLACE FUNCTION myunlock(id_input integer, time_input timestamp) RETURNS integer AS $BODY$ DECLARE BEGIN DELETE FROM ONLY travel_time_locks WHERE id_key=id_input AND time_key=time_input; RETURN 1; END; $BODY$ LANGUAGE 'plpgsql' VOLATILE COST 1;

  • Can I Call a Child Page From a Master Page?

    - by MemphisDeveloper
    My problem is this I have a base page that creates content dynamically. There are buttons on my Master Page that fire events that my base page needs to know about. But the OnLoad function on my base page fires before my Button_Command function on my master page. So I either need to figure out a way to load my base page after the Button_Command function has had the chance to set a variable or I must call a function in my base page from the Button_Command function.

  • ActionScript 2: Event doesn't fire?

    So I have a soundHandler class that's supposed to play sounds and then point back to a function on the timeline when the sound has completed playing.

Have been wasting hours to figure it out already. Any help will be deeply appreciated.

Here is my attempt at converting to MySQLi. <? $database_host = "127.0.0.1"; $database_user = "user"; $database_pass = "pass"; $database_name = "name"; $db = new database($database_host, $database_user, $database_pass, $database_name); class database { var $link, $result; function database($host, $user, $pass, $db) { $this->link = mysqli_connect($host, $user, $pass, $db) or $this->error(); mysqli_select_db($db, $this->link) or $this->error(); } function query($query) { $this->result = mysqli_query($query, $this->link) or $this->error(); $this->_query_count++; return $this->result; } function countRows($result = "") { if ( empty( $result ) ) $result = $this->result; return mysqli_num_rows($result); } function fetch($result = "") { if ( empty( $result ) ) $result = $this->result; return mysqli_fetch_array($result); } function fetch_num($result = "") { if ( empty( $result ) ) $result = $this->result; return mysqli_fetch_array($result, mysqli_NUM); } function fetch_assoc($result = "") { if ( empty( $result ) ) $result = $this->result; return mysqli_fetch_array($result, mysqli_ASSOC); } function escape($str) { return mysqli_real_escape_string($str); } function error() { if ( $_GET["debug"] == 1 ){ die(mysqi_error()); } else { echo "Error in db code"; } } } function sanitize($data) { //apply stripslashes if magic_quotes_gpc is enabled if(get_magic_quotes_gpc()) $data = stripslashes($data); // a mysqli connection is required before using this function $data = trim(mysqli_real_escape_string($data)); return $data; } However it chucks all sorts of errors: Warning: mysql_query(): Access denied for user 'www-data'@'localhost' (using password: NO) in /home/count/Workspace/lib/classes/user.php on line 7 Warning: mysql_query(): A link to the server could not be established in /home/count/Workspace/lib/classes/user.php on line 7 Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given in /home/count/Workspace/lib/classes/user.php on line 8 Warning: mysqli_fetch_array() expects parameter 1 to be mysqli_result, object given in /home/count/Workspace/lib/classes/database.php on line 31

  • Is there a way to catch an attempt to access a non existant property or method?

    - by Tor Valamo
    For instance this code: function stuff() { this.onlyMethod = function () { return something; } } // some error is thrown stuff().nonExistant(); Is there a way to do something like PHP's __call as a fallback from inside the object? function stuff() { this.onlyMethod = function () { return something; } this.__call__ = function (name, params) { alert(name + " can't be called."); } } // would then raise the alert "nonExistant can't be called". stuff().nonExistant();
