  • Backbone.js - Getting JSON back from url

    - by Brian
    While trying to learn Backbone.js, I've been trying to grab the content of a JSON file using the following code: (function($){ var MyModel = Backbone.Model.extend(); var MyCollection = Backbone.Collection.extend({ model : MyModel, url: '/backbone/data.json', parse: function(response) { console.log(response); return response; } }); var stuff = new MyCollection; console.log(stuff.fetch()); console.log(stuff.toJSON()); })(jQuery) 'stuff.fetch()' returns the entire object (with the data I'm after in responseText), 'stuff.toJSON' returns nothing ([]), but the console in the parse method is returning exactly what I want (the json object of my data). I feel like I'm missing something obvious here, but I just can't seem to figure it out why I can't get the right data out. Could someone point me in the right direction or show me what I'm doing wrong here? Am I using a model for the wrong thing?

  • jQuery AJAX PHP JSON problem

    - by Curro
    Hi Gurus I'm facing the problem of receiving an empty array when I do an AJAX request in the following way: This is the code I'm executing in JavaScript: <script type="text/javascript" src="lib/jquery.js"></script> <script type="text/javascript" src="lib/jquery.json.js"></script> <script type="text/javascript"> $(document).ready(function(){ /* Preparar JSON para el request */ var mJSON = new Object; mJSON.id_consulta = new Array; for (var i=0; i<3; i++){ mJSON.id_consulta[i] = new Object; mJSON.id_consulta[i].id = i; } var sJSON = $.toJSON(mJSON); $.ajax({ type: "POST", url: "getUbicaciones.php", data: sJSON, dataType: "json", contentType: "application/json; charset=utf-8", success: function(respuesta){ alert(respuesta); }, error: function (request,error){ alert("Error: " + request.statusText + ". " + error); } }); }); </script> And this is the code under PHP: <?php /* Decodificar JSON */ $m_decoded = $_POST; print_r($m_decoded); exit; ?> And all I get from this, using Chrome's Developer Tools is an empty array: Array ( ) Any clues on what am I doing wrong? The string sJSON is being encoded correctly, this is what I get when I do an "alert" on that one: {"id_consulta":[{"id":1},{"id":2},{"id":3}]} Thank you everyone in advance!

  • DELETE causing a redirect loop?

    - by robocode
    I have an express app with a postgres backend where a user can add/delete recipes, and each time they do so they get an updated list of recipes. Adding a recipe is fine, but when I delete one it seems to get stuck in a redirect loop. In app.js I have router.get('/delete/:d', delRec.deleteRecipe); which calls the following code exports.deleteRecipe = function(req, res){ pg.connect(conString, function(err, client) { client.query('DELETE FROM recipes WHERE recipe_name = ', [req.params.d], function(err, result) { if(err) { return console.error('error running query', err); } else if (result) { pg.end(); console.log('deleting'); } }); }); res.redirect('recipes'); }; If I try delete a recipe, console.log('deleting') produces deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting The recipes route is below (sorry that it's so convoluted) router.get('/recipes', function(req, res) { pg.connect(conString, function(err, client) { if(err) { return console.error('could not connect to postgres', err); } client.query('SELECT * FROM recipes', function(err, result) { if(err) { return console.error('error running query', err); } recipes = result.rows; for(var d in recipes) { if (recipes.hasOwnProperty(d)) { recipeList[d] = recipes[d].recipe_name; } } res.render('recipes', {recipes: recipes, recipeList: recipeList}); }); }); });

  • Does Anyone Know Of A Solid Web Example Using ASP.NET MVC1 or MVC2, NHibernate, Fluent NHibernate &

    - by Sara
    I am looking for solid non-console examples of how to use ASP.NET MVC1 or MVC2, NHibernate, Fluent NHibernate & Castle. I looked at Sharp Architecture and its just too much to digest for my newbie mind. I need a clean, clear, concise Step A, Step B, Step C tutorial or a solid example that is a web application and not a console application. I have searched and searched and searched and I have found incomplete examples (examples with just enough information to make me say where does that code go), console applications and no good web application examples. Does anyone know of a COMPLETE web example? If I see another console example, I'm going to scream....

  • How does System.TraceListener prepend message with process name?

    - by btlog
    I have been looking at using System.Diagnostics.Trace for doing logging is a very basic app. Generally it does all I need it to do. The downside is that if I call Trace.TraceInformation("Some info"); The output is "SomeApp.Exe Information: 0: Some info". Initally this entertained me but no longer. I would like to just output "Some info" to console. So I thought writing a cusom TraceListener, rather than using the inbuilt ConsoleTraceListener, would solve the problem. I can see a specific format that I want all the text after the second colon. Here is my attempt to see if this would work. class LogTraceListener : TraceListener { public override void Write(string message) { int firstColon = message.IndexOf(":"); int secondColon = message.IndexOf(":", firstColon + 1); Console.Write(message); } public override void WriteLine(string message) { int firstColon = message.IndexOf(":"); int secondColon = message.IndexOf(":", firstColon + 1); Console.WriteLine(message); } } If I output the value of firstColon it is always -1. If I put a break point the message is always just "Some info". Where does all the other information come from? So I had a look at the call stack at the point just before Console.WriteLine was called. The method that called my WriteLine method is: System.dll!System.Diagnostics.TraceListener.TraceEvent(System.Diagnostics.TraceEventCache eventCache, string source, System.Diagnostics.TraceEventType eventType, int id, string message) + 0x33 bytes When I use Reflector to look at this message it all seems pretty straight forward. I can't see any code that changes the value of the string after I have sent it to Console.WriteLine. The only method that could posibly change the underlying string value is a call to UnsafeNativeMethods.EventWriteString which has a parameter that is a pointer to the message. Does anyone understand what is going on here and whether I can change the output to be just my message with out the additional fluff. It seems like evil magic that I can pass a string "Some info" to Console.WriteLine (or any other method for that matter) and the string that output is different.

  • Help with shopping cart in javascript

  • Google Chrome is doing things wrong again

    - by Stefan Liebenberg
    Chrome is wrongly reporting width and height values for images during, or just after, load time. Jquery is used in this code example: <img id='image01' alt='picture that is 145x134' src='/images/picture.jpg' /> <script> var img = $( 'img#image01' ) img.width() // would return 145 in Firefox and 0 in Chrome. img.height() // would return 134 in Firefox and 0 in Chrome. </script> If you put the script in a onload function, the result is the same. but if you run the code a few seconds after the page has loaded, chrome returns the correct result. <script> function example () { var img = $( 'img#image01' ); img.width() // returns 145 in both Firefox and Chrome. img.height() // returns 134 in both Firefox and Chrome. } window.setTimeout( example, 1000 ) </script> Also if you specify the width and height values in the img tag, the script seems to work as expected in both Firefox and Chrome. <img id='image01' src='/images/picture.jpg' width=145 height=134 /> But as you cannot always control the html input, this is not an ideal workaround. Can jQuery be patched with a better workaround for this problem? or will I need to specify the width and height for every image in my code?

  • Why does JavaScript's getElementsByClassName provide an object that is NOT an array?

    - by Paragon
    I'm trying to get a list in JavaScript (not using jQuery) of all the elements on the page with a specific class name. I therefore employ the getElementsByClassName() function as follows: var expand_buttons = document.getElementsByClassName('expand'); console.log(expand_buttons, expand_buttons.length, expand_buttons[0]); Note that I have three anchor elements on my page with the class 'expand'. This console.log() outputs [] 0 undefined Next, for kicks, I threw expand_buttons into its own array as follows: var newArray = new Array(expand_buttons); console.log(newArray, newArray.length); This suddenly outputs [NodeList[3]] 1 and I can click through the nodelist and see the attributes of the three 'expand' anchor elements on the page. It's also worth noting that I was able to get my code working in a w3schools test page. It may also be of note that my use of document.getElementsByName actually does output (to the console) an array of elements, but when I ask for its length, it tells me 0. Similarly, if I try to access an array element using array_name[0] as normal, it outputs 'undefined', despite there clearly being an element inside of an array when I print the object to the console. Does anybody have any idea why this might be? I just want to loop through DOM elements, and I'm avoiding jQuery at the moment because I'm trying to practice coding with vanilla JavaScript. Thanks, ParagonRG

The problem is that if it checks the first line and it fails the if statement, if goes through to the else statement and stops. I am trying to find a way where it will stop after the it finds the correct line but not until. If someone types in a value that isn't in the file, then it should show an error.

  • Adding property:value pairs from GooglemapsAPI to an existing json/javascript object

    - by Rockinelle
    I am trying to create a script that finds the closest store/location to a customer using googlemapsAPI. So I've got a json object which is a collection of store objects. Using Jquery's .each to iterate through that object, I am grabbing the driving time from the customer to each store. If it finds the directions, It copies the duration of the drive which is an object with the time in seconds and a human readable value. That appears to work, however when I try to sort through all of those store objects with the drivetime added, I cannot read the object copied from google. If I console.log the whole object, 'closest_store', It shows the values I'm looking for. When I try to read the values directly via closest_store.driveTime, Firebug is outputting undefined in the console. What am I missing here? $.getJSON('<?php echo Url::base() ?>oldservices/get_locations', {}, function(data){ $.each(data, function(index, value) { var end = data[index].address; var request = { origin: start, destination: end, travelMode: google.maps.DirectionsTravelMode.DRIVING }; directionsService.route(request, function(response, status) { //console.log(response); if (status == google.maps.DirectionsStatus.OK) { value.driveTime = response.trips[0].routes[0].duration.value; //console.log(response.trips[0].routes[0].duration.value); }; }); }); var closest_store; $.each(data, function(index, current_store) { if (index == 0) { closest_store = current_store; } else if (current_store.driveTime.value < closest_store.driveTime.value) { closest_store = value }; console.log(current_store.driveTime); } ) });

  • C# Freq. Table with Random Values

    - by Sef
    Hello, I am trying to write a frequency program that will represent a bar diagram (in console code). The problem is i have no idea how exactly to caculate this frequency or how do i exactly then give the bars different heights according to there frequency (trough calculation). The frequency height is capped at 21. (meaning the bars go from 1 to 21, so the max bar height would be for example 21 stars(* as display sign for the bar itself). A calculation i have so far (although not sure if correct) for frequency: This array takes the random values generated: for (int j = 0; j < T.Length; j++) { T[j] = (MaxHeight* T[j]) / Ber.GreatestElement(T); Console.Write("{0,7}", T[j]); } This results in values between 0 and 21 -- Based on the values my bars should give a certain height compared to all the other frequency values. (for example 8000 could have 21 in height where 39 could have 1). To represent this diagram i used 2 for loops to display height and width (keep in mind i only wish to use Using System; to keep it to the "basics"). for (int height= 1; height<= 21; height++) { for (int width= 0; width<= 10; width++) { if(...??) { Console.Write("{0,7}", bar); // string bar= ("*"); } else { Console.Write("{0,7}", empty); } } Console.WriteLine(); } So so far i have a entire field filled with * and the random values generated along with their frequency value (although i have no idea if the freq value is properly calculated). I assume i need a if (.....) in the second for but i cannot seem to get further then this. Thanks in advance!

  • How to Regex.IsMatch at a specified offset in .NET?

    - by romkyns
    Suppose I want to match "abc" within the string s only if it occurs exactly at index n. int n = 2; Console.WriteLine(new Regex("abc").IsMatch("01abc", n)); // true Console.WriteLine(new Regex("abc").IsMatch("0123abc", n)); // true (but want false) Console.WriteLine(new Regex("^abc").IsMatch("01abc", n)); // false (but want true) Seems that the only way to achieve this without using Substring on the input is something like this: var match = new Regex("abc").Match("0123abc", n); Console.WriteLine(match.Success && match.Index == n); This isn't too bad, except that when there is no match at the starting offset then the entire input will be scanned unnecessarily, which is probably slower for most regexes than actually creating a substring prior to the match. (I didn't time it though). Am I missing an obvious overload or setting that would restrict a match to the supplied offset only?

  • Problem accessing private variables in jQuery like chainable design pattern

    - by novogeek
    Hi folks, I'm trying to create my custom toolbox which imitates jQuery's design pattern. Basically, the idea is somewhat derived from this post: http://stackoverflow.com/questions/2061501/jquery-plugin-design-pattern-common-practice-for-dealing-with-private-function (Check the answer given by "David"). So here is my toolbox function: (function(window){ var mySpace=function(){ return new PrivateSpace(); } var PrivateSpace=function(){ var testCache={}; }; PrivateSpace.prototype={ init:function(){ console.log('init this:', this); return this; }, ajax:function(){ console.log('make ajax calls here'); return this; }, cache:function(key,selector){ console.log('cache selectors here'); testCache[key]=selector; console.log('cached selector: ',testCache); return this; } } window.hmis=window.m$=mySpace(); })(window) Now, if I execute this function like: console.log(m$.cache('firstname','#FirstNameTextbox')); I get an error 'testCache' is not defined. I'm not able to access the variable "testCache" inside my cache function of the prototype. How should I access it? Basically, what I want to do is, I want to cache all my jQuery selectors into an object and use this object in the future.

  • Font for tabs looks a little too big

    - by cf_PhillipSenn
    I'm using the default for jQueryUI, but it looks like the font is a little big. I know that one solution would be "WELL! JUST MAKE IT SMALLER!", but I'm just wondering if I've messed something up or I don't have a value set correctly before I charge in and start changing things. <!DOCTYPE HTML> <html> <head> <script src="http://www.google.com/jsapi"></script> <script type="text/javascript"> google.load("jquery", "1"); </script> <link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1/themes/smoothness/jquery-ui.css" type="text/css" media="all" /> <script type="text/javascript"> google.load("jqueryui", "1"); function OnLoadCallbackUI(){ $('#tabs').tabs(); } google.setOnLoadCallback(OnLoadCallbackUI); </script> </head> <body> <div id="tabs"> <ul> <li><a href="#tabs-1">tab1</a></li> <li><a href="#tabs-2">tab2</a></li> </ul> <div id="tabs-1"> tabs-1 </div> <div id="tabs-2"> tabs-2 </div> </div> </body> </html>

  • C# object (2 numbers) performing 2 calculations

    - by Chris
    I have a couple questions about creating a object (2 values) and how to "call" it. Initializing the object with: Tweetal t1, t2, t3, t4, t5, t6; t1 = new Tweetal(); //a: 0 , b = 0 t2 = new Tweetal(-2); //a: -2, b = -2 t3 = new Tweetal(5, 17); //a: 5, b = 17 t4 = new Tweetal(t3); //a:5, b = 17 Console.Write("t1 = " + t1); Console.Write("\tt2 = " + t2); Console.Write("\tt3 = " + t3); Console.Write("\tt4 = " + t4); Console.WriteLine("\n"); t1 = t1.Som(t2); t4 = t2.Som(t2); //...... Now the 2 things i want to do with this object are taking the SUM and the SUMNumber: Sum: t4 = t2.sum(t3); (this would result in t4: a:3 (-2+5), b: 15(-2+17) SumNumber: t1 = t3.sum(8) (this would result in t1: a:13 , b:25) Next is my code for the object (in a separate class), but how exactly do i perform the simple sum calculation when i call up for example t2 etc... public class Tweetal: Object { private int a; private int b; public Tweetal() { //??? //Sum(...,...) } public Tweetal(int a) { //??? //Sum(...,...) } public Tweetal(int a, int b) { //??? } public Tweetal(Tweetal //....) // to call upton the object if i request t1, t2, t3,... insteed of a direct number value) { // ???? } public void Sum(int aValue, int bValue) { //a = ??? //b = ??? //Sum(...,...) } public void SumNumber(int aValue, int bValue) { } public override string ToString() { return string.Format("({0}, {1})", a, b); }/*ToString*/ }
