JavaScript - Array In Prototype Gives Wrong Results
The code below looks elementary, but it gives absurd results.
Can you tell how I should have written it? I am slowly beginning to understand why it fails. But I do not understand why the JavaScript tutorials I've studied never warned against this trap. Any ship needs a list of crew members. The total number of persons onboard must be known too, for the case the ship sinks. We place these two properties in a prototype, so that we won't have to repeat them for each kind of ship. A passenger list is needed only if the ship is a passenger ship, so we decide not to place the passenger list in a prototype. Code:
function Ship() {
this.crew = [];
this.persons = 0;
}
function PassengerShip(name) {
this.name = name;
this.passengers = [];
}
PassengerShip.prototype = new Ship;
Passengers and crew arrive one by one shortly before departure. The first thing they do onboard is to check in: Code: Ship.prototype.checkin = function(list, person) {
this[list].push(person);
++this.persons;
}
(Instead of the push function, we could as well have used a statement such as Code: this[list][ this[list].length ] = person; I have tried. Same wrong result.) Let us launch two passenger ships and check some persons in. Code: var msFloat = new PassengerShip("M/S Float");
msFloat.checkin("crew", "Captain");
msFloat.checkin("crew", "Cook");
msFloat.checkin("passengers", "Alice");
msFloat.checkin("passengers", "Bob");
var msFlawed = new PassengerShip("M/S Flawed");
msFlawed.checkin("crew", "Capt'n");
msFlawed.checkin("crew", "Sailor");
msFlawed.checkin("passengers", "Charlie");
The shipping company wants a report when everybody has checked in. But I'm not sure they will like it: Code: Ship.prototype.report = function() {
function makeList(ship, list) {
if (!ship[list]) return (ship.name + " has no list of " + list + ".\n");
if (!ship[list].length) return (ship.name + " has no " + list + ".\n");
return (list + ": " + ship[list].join(", ") + "\n");
}
alert("\nPre-Departure Report For '" + this.name + "'\n\n" +
makeList(this, "passengers") + makeList(this, "crew") +
"\nNumber of persons onboard: " + this.persons + "\n\n");
}
msFloat.report(); // OK: Alice, Bob as passengers; Captain, Cook as crew
msFlawed.report(); // WRONG CREW: Captain, Cook, Capt'n, Sailor
The number of persons (passengers + crew) is reported correctly for both ships, and so is the passenger list. But the "M/S Flawed" reports four crew members. Two of those never checked in on that ship. How can such a thing happen? What kind of blunder did I make? An "edit+execute" version of the code is available at bjarne.altervista.org/sailor.html together with a little testoutput, some considerations based on that testoutput, and a workaround (which is not the same as a solution - it looks ridiculous). It seems as if arrays placed in prototypes do not always work as expected. Can that be true? The testoutput suggests that JavaScript sometimes forgets to create a much-needed own property in the this object, and instead changes the prototype. But that sounds incredible, doesn't it? I am not too familiar with the deeper theory of JavaScript, and I hope to get a response. Here is the code concatenated and embedded: Code: <?xml version="1.0" encoding="utf-8"?>

I have spent much time struggling with this kind of error, which is reproducible in 5 different browsers. This is the first time I have been able to reproduce it in a form that can be presented to others. Is there a well-established programming practice that can prevent it? What do experienced JavaScript programmers do? Regards Bjarne Pagh Byrnak Similar TutorialsArray.prototype.each = function (fn) { this.map(fn) } This is my each function that works great in every other browser but IE. UGH! What am I doing wrong? the error points to the this in the function. Is it that IE doesn't like map? Has anyone seen this before? I thought my code was correct. Works perfect in FF, chrome and opera. the canvas text doesn't work in opera, but it does render the features so the each function is working. I'll post the code if needed, but it's huge. here's the script running. http://www.pdxbusiness.com/canvas/golf/ Hi, all~..According to ECMAScript, the root of the prototype chain is Object.Prototype. Each object has an internal property [[Prototype]] that could be another object or NULL.... However, it also says that every function has the Function prototype object: Function.Prototype, it confused me, because a function is an object, for a function object, what is its function prototype and object prototype..For example: Code: var x = function (n) {return n+1;};
what is the relationships of x, Object.Prototype and Function.Prototype
Thx a lot !!!!!!!!! I have this simple php array. The array will dynamically pull results from the db in the future. PHP Code: <?php $dataArray = array ( 'id1' => array ( 'icon' => '<img src="images/piicon.png">', 'app' => 'GGP', 'timestamp' => date('m/d/y'), 'location' => 'Bellevue', 'comments' => 'It works!', ), 'id2' => array ( 'icon' => '<img src="images/piicon.png">', 'app' => 'Meijer', 'timestamp' => date('m/d/y'), 'location' => 'San diego', 'comments' => 'It works!', ), 'id3' => array ( 'icon' => '<img src="images/piicon.png">', 'app' => 'Point Inside', 'timestamp' => date('m/d/y'), 'location' => 'Boston', 'comments' => 'I guess its working? Maybe not exactly what we want yet though?!', ) ); echo json_encode($dataArray); ?> Currently if I have 100 results in my array, 100 results will be added to the table, 75 = 75 rows etc. What I am trying to plan out is a logical way to display one result from the array at a time. I am not looking for a chunk of jquery as an answer, better yet would be a plan/idea a programmer would you use to solve this. PHP Code: $(document).ready(function() { setInterval(function() { // get data $.ajax({ url: '/ajax/data.php', type: "GET", cache: false, error: function(data) { $("div#error").html('error: '+data); }, success: function(data) { var jsonObj = jQuery.parseJSON(data); jQuery.each(jsonObj, function(index, value) { var newRow = $("<tr><td>"+value.icon+"</td><td>"+value.app+"</td><td>"+value.timestamp+"</td><td>"+value.location+"</td><td>"+value.comments+"</td></tr>"); $("#mainTable tbody").prepend(newRow); }); } }); }, 5000); }); thanks All, I have the following code: console.log("My num is: " + num); console.log("My lat is: " + lat); console.log("My lat length is: " + lat.length); console.log("My long is: " + long); When I get the output, I get the following: My num is: {"1":1,"2":2} My lat is: {"1":"40.59479899","2":"41.4599860"} My lat length is: 36 My long is: {"1":"-75.5549650","2":"-87.596430"} I'm confused on why the length is saying 36 when it's obviously two and the other output shows that??? Right now I am trying to grab all the links on a html page a store them in an array so that they can be accessed by a loop that makes sure that each one works. Right now I am not getting very far with it. If someone could help me I would be greatly appreciative.
I'm trying to display a random message by making an array through values in an XML file and then displaying the info on the page. i want to have it so that a new message is generated each time the button is clicked with no repeats. here is what i have Code: function initial()

var xmlDoc;
// First option for internet explorer 5 and 6, second option for firefox, internet explorer 7+
window.ActiveXObject ? xmlDoc = new ActiveXObject("Microsoft.XMLDOM") : xmlDoc = document.implementation.createDocument("","",null);
xmlDoc.async = false;
xmlDoc.load("quotes.xml");
// take the quote and author information from the xml file
var pQuotes = xmlDoc.getElementsByTagName('quote');
var pAuthors = xmlDoc.getElementsByTagName('author');
// create arrays
var aQuotes = new Array();
var aAuthors = new Array();
// put the quotes into the array
for (i=0; i<pQuotes.length; i++)
{
aQuotes.push(pQuotes[i].childNodes[0].nodeValue);
alert(pQuotes);
}
// put the authors into the array
for (i=0; i<pAuthors.length; i++)
{
aAuthors.push(nAuthors[i].childNodes[0].nodeValue);
}
// Loop through arrays and print their quotes and authors
for (var s in aQuote) {
alert(aQuotes[s]);
alert(aAuthors[s]);
}
}
var Q = aQuotes.length;
var quoteText = document.getElementById('aQuotes');
var authorText = document.getElementById('aAuthors');
var randomquote = Math.floor(Q * Math.random());
function quoter() {
var randomquote2 = randomquote;
while (randomquote == randomquote2)
{
randomquote = Math.floor(Q * Math.random());
}
document.getElementById('quoteText').innerHTML = aQuotes[randomquote];
document.getElementById('authorText').innerHTML = " - " +aAuthors[randomquote];
quote.innerhtml = aQuotes[randomquote];
author.innerhtml = aAuthor[randomquote];
}

I have this php query result he $id = $facebook->api(array('method' => 'fql.query', 'query' => "SELECT uid FROM user WHERE uid IN( SELECT uid FROM page_fan WHERE page_id='411133928921438' AND uid IN ( SELECT uid2 FROM friend WHERE uid1 = me() ))")); And i need to save it as an array like: var user_ids = [x,y,z] etc etc... I have used the json_encode but it isn't working... here is my code.. Code: var user_ids = <?php echo json_encode($id); ?>; How can i retrieve the query results, the id's in an array like i mentioned above? Please help me... Hello, another noob question for you: I have a function that requires the ability to count the number of entries in an array. I'm using the following to call my function inside an input tag: Code: onblur="javascript:check(this.name, this.value, 1, 10);" which for example is calling check('field1', 'foobar', 1, 10) Here is the javascript: Code: function check(name, value, min, max){
var errors=new Array();
if(value.length < min || value.length > max){ //checking against min/max length of value
errors[name] = "Text field must not be blank.";
errors["blabla"] = "array value 2"; //added for testing purposes
alert(name+" : "+value); //returns "field1 : foobar"
}
alert(errors.length); // returns "0"
}
And when errors.length is alerted, it outputs 0. I can only figure that there is an issue when using custom named keys in an array, since this works when I use only integers, however, I have the need to use a custom key index as shown. Any ideas? im currently using a prototype add on for one of my sites and id like to convert it to mootools... problem is, i dont know the first thing about prototype! i stumbled upon this before i learned any javascript and ive gotten to know mootools and like using it... heres the code, let me know if anyone can help!

It's code to make the scrollbars autoscroll down. Full article and extra info he http://radio.javaranch.com/pascarell...837038219.html I sort of understand it but I'm not clear on what prototypes are. hi, I'm trying to inherit with prototype but I'm not able to do so. The problem is that I have a few functions which use some common variables and common functions and I want to inherit a Resource object with all these parameters. I also whant this inheritance to be done when I load the function, so no extra functions are loaded unless I need them. Here's the code Code: function Resource(){
this.url='';
this.object=new Object();
this.id='';
this.categories=new Array();
}
function Users(){
Users.prototype=new Resource();
this.url='user/';
this.name='';
this.email='';
};
function test(){
var users = new Users();
alert(users.id);
};
When I run the test function for the first time I get an undefined. a second time works fine. I I get the prototype definition outside the User() function it also works fine, but I want the inherited function to be loaded when I need it. Any ideas? As always, thank you for your help. hi, i'm currently stumped by the following code. what's the point of using x.constructor.prototype? (highlighted in red) why not directly use x.prototype.classname to check whether 'classname' property is in this class? thx in advance Code: function getType(x) {
// If x is null, return "null"
if (x == null) return "null";
// Next try the typeof operator
var t = typeof x;
// If the result is not vague, return it
if (t != "object") return t;
// Otherwise, x is an object. Use the default toString( ) method to
// get the class value of the object.
var c = Object.prototype.toString.apply(x); // Returns "[object class]"
c = c.substring(8, c.length-1); // Strip off "[object" and "]"
// If the class is not a vague one, return it.
if (c != "Object") return c;
// If we get here, c is "Object". Check to see if
// the value x is really just a generic object.
if (x.constructor == Object) return c; // Okay the type really is "Object"
// For user-defined classes, look for a string-valued property named
// classname, that is inherited from the object's prototype
if ("classname" in x.constructor.prototype && // inherits classname
typeof x.constructor.prototype.classname == "string") // its a string
return x.constructor.prototype.classname;
// If we really can't figure it out, say so.
return "<unknown type>";
}
G'day, How would I go about copying all the prototype functions AND the constructor from one object into another object, and then call them? Code: function myOriginal() {
alert('Hello');
}
myOriginal.prototype.example = function() {
alert('In example '+this.test);
}
function myNewThing() {
// Copy myOriginal into this object here
this.oldconstructor(); // Should now display "Hello"
this.test = 'from myNewThing';
this.example(); // Should now display "In example myNewThing"
}
I know I can use this.example.call(this), but that's not an acceptable solution. I want to deploy this style over dozens, potentially hundreds of objects. Thanks muchly, Your friend from server-side... Hi there I am trying to retrieve xml data using the prototype Ajax.Request. I think I am getting the xml though I am unsure as to how to retrieve the text from the nodes here is the function I am using to try and populate a text field Code: function makeMarkerXml() {

can anyone help? Hi, I'm trying to use a javascript tabstrip script called aptabs, which uses prototype.js. However, prototype.js won't load properly, because the following error occurs in prototype.js: destination is undefined on the following line (3042): destination[property] = value.methodize(); The function this line is in is: Code: function copy(methods, destination, onlyIfAbsent) {
onlyIfAbsent = onlyIfAbsent || false;
for (var property in methods) {
var value = methods[property];
if (!Object.isFunction(value)) continue;
if (!onlyIfAbsent || !(property in destination))
destination[property] = value.methodize();
}
}
I've tried using versions 1.6.0 all the way up to 1.6.1, but I still get the same error. Can someone suggest what this error could be caused by and possible fixes? Debbie Hi I am using a program called aptabs which uses the Protoype framework. The problem is that when I create a new tab and refresh the page, the newly created tab disappears. How can I resolve this ? NOTE: The zip file for aptabs is attached. Thanks Hey All - I asked this a few days ago.. what I came up with works just fine, but I feel it doesn't take advantage of "classes". If you think I could make this better by turning it into a class or using some other notation, that would be great. Keep in mind, ALL this does is rewrite a pagination.... for a search return in a lightbox. I have this function called in the return function... Code:
var srcpagParams = $H();
function buildPagi(param, currdsplyNum){
var temDsply = new Template('<strong>[#{total_display}<span id="count">#{prevImg} #{links} #{nextImg}</span>'),
crnt_link = srcpagParams.set('crnt_link', param), // the page we want to see
dsplyNum = srcpagParams.get('paginateNum'), // what is the number of returns per page
ttl_lnks = Math.ceil( srcpagParams.get('numFound') / srcpagParams.get('paginateNum')), // total pages
data_template = new Hash();
data_template.set('total_display',srcpagParams.get('numFound'));
bldImg = function() {
var prvB = '<a href="#content" id="pagiPrev" onclick="firesrc(this)">Prev<img src="blank.gif" /></a>';
var nxtB = '<a href="#content" id="pagiNext" onclick="firesrc(this)">Next<img src="blank.gif" /></a>';
data_template.set('prvImg',(crnt_link > 1) ? prvB : "");
data_template.set('nxtImg',(crnt_link < ttl_lnks) ? nxtB : "");
}
bldLk = function(){
var holder = "";
if(ttl_lnks > 1){
var linkStr = new Template(' <a href="#content" onclick="firesrc(#{pos});"> Go to page #{pos}</a> ');
$R(1,ttl_lnks).each(function(n) {
var posit = {pos : n}
holder += (crnt_link == n) ? " " + n + " " : linkStr.evaluate(posit);
});
data_template.set('links',linkholder);
}
}
bldRng = function(){
var currPaneRg = (dsplyNum * crnt_link) - (dsplyNum - currdsplyNum);
data_template.set('range',((crnt_link - 1) * (dsplyNum) + 1 ) + " - " + currPaneRg);
$('pages').update(temDsply.evaluate(data_template)).show();
}
firesrc = function(cl){
var pagiPane = (typeof cl === "number") ? cl : (cl.id == "pagiNext") ? crnt_link + 1 : crnt_link - 1;
var start = crnt_link * srcpagParams.get('paginateNum');
Alertsrc( $F('query') ,(pagiPane)) // pass the query to the json to return the current search request
}
bldImg();
buildLnk();
bldRng();
};
Since some of the data declared at the top changes depending on the return, I didn't know if I could "initialize" it in a class.
But could I turn this into a class and if so - what I just use:
var buildPagi = create.Class({
initialize: object.extend({
})
})
Call the function when we are passed some data: Code: buildPagi(somevalue, somevalue2) ** NOTE: I use the libraries prototype and jquery.. so use Create.Class and new Template are within the libraries... etc.. so, is there a more eloquent, or robust way to write what I did above? Hello all I have been trying in vain for many days to resolve a conflict between javascript libraries. I have read far and wide and still have failed to fix this problem, most likely because my programming skills are just about copy and pasting. My homepage uses jquery horizontal css menubar + a combined mootool and prototype accordian type sliding information box in the middle of the webpage. I find that the highlighter of the css menubar does not work when prototype.js is also loaded on the same page. I have read somewhere that $ should be replaced however I have tried every possible option and none works. I have jquery loading first as it is on my template, with this <script type='text/javascript' src='../Web/Templates/jquery-1.3.2.js'></script> <script type='text/javascript' src='js/example.js'></script> And my mootool and prototype loades further below like this <script type="text/javascript" src="scripts/intro/prototype.lite.js"></script> <script type="text/javascript" src="scripts/intro/moo.fx.js"></script> <script type="text/javascript" src="scripts/intro/moo.fx.pack.js"></script> <script type="text/javascript"> function init(){ var stretchers = document.getElementsByClassName('box'); var toggles = document.getElementsByClassName('tab'); var myAccordion = new fx.Accordion( toggles, stretchers, {opacity: false, height: true, duration: 600} ); //hash functions var found = false; toggles.each(function(h3, i){ var div = Element.find(h3, 'nextSibling'); if (window.location.href.indexOf(h3.title) > 0) { myAccordion.showThisHideOpen(div); found = true; } }); if (!found) myAccordion.showThisHideOpen(stretchers[0]); } </script> Could someone please offer me further assistance and enlighten me what other information you require to assist me further. I have attached the example.js inside example.zip file if someone could kindly edit it for myself. Looking forward to your assistance. Sincerely, Lex Hello, I'm trying to write my class with member properties and functions like below. What I want to learn is that is there any problem to use prototype object in the class that we want to use with it? I asked because I generally see that prototype object definition and member functions and properties created outside of the class unlike my class that I wrote like below. Is there any problem writing my class like below? Thanks. Code: function Point()
{
Point.prototype.x = this._x;
Point.prototype.y = this._y;
function _setX(x)
{
this.x = x;
}
Point.prototype.setX = _setX;
function _setY(y)
{
this.y = y;
}
Point.prototype.setY = _setY;
function _show()
{
alert(this.x + this.y);
}
Point.prototype.Show = _show;
}
function callMyClass()
{
var p = new Point();
p.setX(3);
p.setY(5);
p.Show();
}
