I am using the module pattern and private/public methods. I'm having a problem where the private method is using setTimeout() to call itself recursively, but I can't get the syntax right. Code:

I'm trying to do something, but I don't know if it's possible.
Basically, I want to have a public static class method that could
access a private object's method. I would like to be able to do :
Class.method(InstanceOfClass);
The method would then access a private function from Class by doing
something like
function method(param) {
param.privateMethodOfClass();
}
I've done a lot research and experimentations but just can't come up
with a solution... I don't even know if what I'm trying to do is
possible.
I would like to know if there is a simple way to show all elements of that variable?
var collectionElements = {
teste: {
var1: 'teste[]',
[Code].....
With this function my firebug Console outputs only the last object(3th node) with its child object.
Is there a Jquery method I could use to quickly parse a JSONP object, looking for an embedded object called "error" ?? If I were to do the following:
jQuery.each(query.data.error, function(i,error){ //....}
And there wasNO .error in the returned JSON, what should I expect to happen? Basically, I want to know if "error" is in the JSON and process accordingly.
I am working on creating a JSON feed that is later being used with Arshaw's fullCalendar, which I am integrating into Expression Engine CMS. Currently I am doing the following, and all works well.
<?php $ms_title_array = array(); ?>
<?php $ms_start_date = array(); ?>
<?php $ms_due_date = array(); ?>
[code]....
What I am curious about is I am trying to create another array set that is pulling new information from a different source. Is it possible to use the json_encode(); method to encode two separate variables?If not, is there a way I can create the event variable and store both the information you see in the while loop with information that I would store into a new while loop? I'm a little stumped
I tried to pass the external JSON object on validate method. But It's not working.

View 2 Replies View RelatedMy web application does user authentication through X.509 digital
certificates in combination with user name and password.
When the user applies for a digital certificate from my certification
authority (CA), I have a VBScript code that generates a public/private
key pair with the RSA algorithm, as well as the certificate signing
request (CSR) in PKCS#10 format. I assume that the key pair should be
maintained by the browser (my application support Internet Explorer
only at this moment). Am I right?
Now, when the user tries to log into his account, I would like to have
my web application receive a digitally signed token from the client.
The token can be the client's username signed with his/her private
key.
Since this signing process will happen on the client side, it can only
be handled by client side script, for example, JavaScript.
But, how do we get access to the private key with JavaScript?

Each of my records has a name, dob and id of each parent.... How can I get X generations from this.. I thought something like this might work.. GetParents For each parent GetParents And so on... But I have no idea how to put this into code...

already in a folder function 1 for each file in folder add file to webpage next folder function2 function2 for each folder within folder call function 1
I know the code isn't all that clear, but that's the best way I can describe it.
What do you think about emulating private variables for a class this
way?
function Something() {
var private;
Something.prototype.getPrivate = function() { return private; }
Something.prototype.setPrivate = function(newPrivate) { private =
newPrivate; }
}
var some = new Something("My private");
alert(some.getPrivate());
alert(some.setPrivate("Nyah nyah"));
alert(some.getPrivate());
That way the accessor methods instances are shared among instances of
Something. What do you think?
I'm trying to create an extensible class with private members.
Suppose I have the following:
Code:
Obviously, only "y" should be available to instantiations:
Code:
But how can I now extend this class and still access the private properties inside the extension?
Code:
How do I access x there? The someOtherFunction extension is part of the prototype, so it should be in the same scope as someFunction, no?
I want to be able to set a property on a private object by giving the not notation path to the value. The difficulty is that this object is within closure so I can't access it directly to set the value the normal way (eg. dot.notation.path = 'new value'). This seems weird but I can't think of the obvious way.
Example:
// setter function
function set(path, change){
var privateObject = {
a: 'a',
[Code]....
i have something like this:
Code:
var o = {
f1:function(a) {

I am having trouble with a recursive function I created to list out the indexes and values of various nested objects.
var macros={
CTRL: {
ALT: {
ENTER: "<br />",
P: "<p>.</p>",
A: "<a href="">.</a>",
_1: "<h1>.</h1>",
_2: "<h2>.</h2>",
_3: "<h3>.</h3>",
_4: "<h4>.</h4>",
_5: "<h5>.</h5>",
_6: "<h6>.</h6>"
}}};
I want to print out the whole 'bread crumb trail' to each object, ie CTRL ALT 6: <h6>.</h6>, but at the moment my function prints out CTRL ALT twice for 'ENTER' and then never again. The function:
function printObj(obj) {
for(i in obj) {
var n=i.replace("_", "");
document.write(n);
if(typeof obj[i]=="string") {
document.write(":");
document.write(" "+obj[i].replace(/</g, "<").replace(/>/g, ">"));
} else {
document.write(n);
}
if(typeof obj[i]=="object") printObj(obj[i]);
document.write("
");
}}
printObj(macros);
The current output:
CTRLCTRLALTALTENTER: <br /> P: <p>.</p> A: <a href="">.</a> 1: <h1>.</h1> 2: <h2>.</h2> 3: <h3>.</h3> 4: <h4>.</h4> 5: <h5>.</h5> 6: <h6>.</h6>
I have this script. It's supposed to give the Fibonacci numbers but the recursion won't work. It just prints out 1 number that the user entered and that's it. In IE6 it prints 1 number but in Firefox it prints the same number an infinite number of times. Whats going on? Here is the script:
<html>
<head>
<script language = "javascript">
function fib(form)
{
var fibVar = Number(document.myform.inputbox.value);
document.write(fibVar);
if(fibVar == 0 || fibVar == 1)
return fibVar;
else return fib(fibVar - 1) + fib(fibVar - 2);
}
</script>
</head>
<body>
<form name="myform" action="" method="get">
<input type="text" name="inputbox"><br>
<input type="button" name="button1" value="Calculate"
</form>
</body>
</html>
I've got a plugin which is structured as follows:
(function($) {
$.fn.MyFunction = function(o) {
// Here we have some parameters
return this.each(function() {
[Code].....
So what I'm looking for is how to reference MyExternalFunction from my html script. I've tried simply using MyExternalFunction(index) but I get function undefined.
This question applies to javascript generally as opposed to jQuery specifically. I want to be able to structure my scripts into classes, then create them using the "new" keyword, but here is the important bit: How do I make a js function private (or public for that matter)?
View 4 Replies View RelatedI have some confusion about the scripts below:
1) is getRule a local variable or global variable, as it has no var keyword, yet it is an inner function of Validation? So without var, I think global, but being an inner function, I think local. So I'm not sure which.
2) In this line of code: var rule = $.Validation.getRule(types[type]), getRule returns rules, which is just a local variable in Validation. I always see that you return functions, but how does returning a local variable that's just an object literal and not a function be able to return true or false? Now the value of rules is an object literal, and this object returns true or false. So we are basically allowed to use return keyword with local variables that are object literals and not functions?
3) In this line, is foo(age) being called, or is it just being assigned to bar OR is it being called and THEN assigned to bar: var bar = foo(age);
4) Now for the most confusing: age is obviously an object reference as opposed to a literal in the example. Does that make a difference in regards to closures?
Note that I read a number of books, including JavaScript Programmer Reference and Object Oriented JavaScript and jQuery cookbook, which compare primitives vs reference types and how primitive types store directly in memory whereas reference tpyes reference memory, so if one reference changes, they all change where primitive remains ingrained. But when assigning a function as a reference like this, how does that affect the object "age" when passed into bar?
Code:
(function($) {
/*Validation Singleton*/
var Validation = function() {
var rules = {
email : {
check: function(value) {
if(value)
return testPattern(value,".+@.+..+");
return true;
}, .....
$.Validation = new Validation();
})(jQuery);
Code:
function foo(x) {
var tmp = 3;
return function (y) {
alert(x + y + tmp);
x.memb = x.memb ? x.memb + 1 : 1;
alert(x.memb);
}}
var age = new Number(2);
var bar = foo(age); // bar is now a closure referencing age.
bar(10);
Firebug returns an error and I like to ask you how I could improve my code.

I have a JSON structure in API.When I call the API in my code it returns as the same JSON .I have to print this JSON result as table with pagination in Javascript. The table should be dynamic with previous and next buttons and the table should populate the results according to the JSON and each page should have 20 entries and then the remaining entries should go on the next page and I should be able to go back and forth in the table using previous and next respectively.tell me the exact code of how to start with getting JSON from the API and then write the JSON data in the form of dynamic table with pagination.
View 1 Replies View RelatedI am trying to create a private chat from hacking some opensource chat room.I am trying to use some basic AJAX (noobie) to insert a field into a mysql db.It is doing what I want it to do mysql wise but it also changes the url.
my site runs like this. There is a page called private.php with all the php in. private.php has a switch statement to call other pages (the default is home.php).so if a user say clicks contact the link would be private.php?mode=contact.and then in the private page the switch statement would
case "contact":
require("contact.php");
break;
so the user has searched another user and wants to chat.the url at the moment is private.php?mode=full_profile&id=101 in the full_profile.php page I have the ajax in the head and a submit form to call the ajax function.
here is the ajax code
<script language="javascript" type="text/javascript">
<!--
//Browser Support Code
function ajaxFunction(){
[code]....
now the mysql query runs fine. the problem I have is that when I click the submit the url changes to private.php?x=18&y=28 . (the x and y vales are different everytime I click the submit).can anyone tell me where the x and y values are coming from and also why the ajax function is changing the url as the whole point of using ajax is to avoid that.
I'm using the standard module pattern and the problem is once you set a private variable, trying to test that object independently becomes a nightmare as the next test is polluted by the actions of the previous.So, the options are to have some reset method (which is horrible), setters on everything (defeats the point) or delete object and re-load script (hideous).
View 2 Replies View RelatedWhy is the callwhy is the slice method only a method of an Array instance? The reason why I ask is because if you want to use it for the arguments property of function object, or a string, or an object, or a number instance, you are forced to use Array .prototype slice.call(). And by doing that, you can pass in any type of object instance (Array, Number, String, Object) into it. So why not just default it as a method of all object instances built into the language?In other words, instead of doing this:
function Core(){
var obj = {a : 'a', b : 'b'};
var num = 1;[code]....
//right now none of the above would work but it's more convenient than using the call alternative.
}
Core('dom','event','ajax');
Why did the designers of the javascript scripting language make this decision?
I am using jQuery form plugin to submit my form. It has a file element and when where I am submitting it I am getting "too much recursion" in Firefox. It looks fine in IE 8. It works fine if I submit the form without selecting any file.
I am calling ajaxForm() methid this way.
jQuery("#myForm").ajaxForm();
