I tried load method super as smartupdater orPeriodicalUpdater (Prototype). Now the problem is that I have to build a cycle (loop) and each time I have to change the time (that I take from database) so how method (function) can I use to load external code (example load()) modifying continuosly the timeout?

One thing I haven't figured out about javascript is the treatment of
__proto__.
Inheritence, whether prototypes or class-based, is just a shorthand
form of delegation (leaving aside dynamic dispatch).
In Java a derived class serves as a wrapper for its superclass. The
derived class can easily access members of its super class using the
nice "super" keyword. Why, in javascript, is this functionality buried
in the unofficial "__proto__" property? It seems that it must have
been the intent of the language designer that explicitly accessing the
prototype chain is a bad thing for some reason, although I can't see
any reason.
By googling, you can find a lot of weird hacks to add "super"-like
functionality to javascript, although many of them look misguided to
me. It certainly seems that this is a commonly confusing part of the
language.
If __proto__ were an official part of the language, implementing a
decorator or proxy pattern would be nicely simplified compared to
class-based inheritence. The "before-and-after" style of AOP (which is
just another style of shorthand for delegation) would be possible
without any crazy tricks.
So, anyone care to set me straight? Why isn't __proto__ or something
like it a well defined part of javascript? Shouldn't it be?
The code is supposed to generate this: PS: This is generated by a PHP Function that the Ajax Load Method Calls.
[Code]...
I've been noticing a lot of problems when loading these stuff, Sometimes I have to remake the HTML Tags because its not showing anything. Is there any option? I want it to load EXACTLY how it is, I don't know if this is some kind of protection for bad code, but if it is I would like to disable. But also, this code is really clean. no problem, I don't know.
Is it faster/more beneficial to have two snippets of code be generated by php at 2 different urls and then have a load function for each url? Or have the two snippets on one page, surrounded by id's and then load them that way?

View 1 Replies View RelatedI'm loading content with the .load() method. How do i only allow oneclick to the link. I don't want future clicks to keep loading the samecontent.
$(document).ready(function(){
$("#FAQ").click(function(){
$('<div id="faqcontent" />').load("content.htm #faqs" , function(){
[code]....
in this example: $(el).load('/data_url', function() { alert('loaded') } );
will the alert be called after the html fragment has been loaded into el and all its elements are available to access or is the callback just after the ajax call has finished ?
I'm trying to use the ajax load() method to load a file from a parent directory, e.g.
$("#divTests").load("../tests.htm");
But that doesn't work. I can load a simple html file from the same directory as my html file or a descendant directory, but not an ancestor directory. Nor can I load from an external server.
I'm doing my testing on my PC and I'm not running a server (apache or otherwise). Just using it as a simple client. Is that possibly the problem? Or is there something else I'm missing? If that is the problem, is there a workaround?
I use $().load() to place an HTML snippet from the server into a dialog box which i then need to position relative to the size of the element which has just had the HTML loaded into it. When the main HTML page DOM is ready, I hide() the dialog box, and then use fadeIn() to show with various click() events. I have managed to position the dialog box in the centre of the screen given that there is no content loaded.
However, it seems that when I load the new content into the dialog box the new dimensions aren't taken into account untill the next time load() is called.
Is there a way to get the new dimensions of the element before the dialog is shown in order to position it centre screen?
Here is my code:
function showDialogBox(sender) {
var width = $(document).width();
var height = $(document).height();

Got the following code, which loads some html into a div, then set's the focus to a textbox:
This works fine with 1.4.2, but with 1.4.3 I get an error in jquery-1.4.3.js using Firebug: handler is undefined Line 1797
This happens on line 2 of the code
To me it looks as if the wrong .load method is being called, from the jQuery docs:[url]
Note: The event handling suite also has a method named .load(). Which one is fired depends on the set of arguments passed.
I think the event .load method is being called because line 1797 in jquery-1.4.3.js
if ( handler.handler ) {and comments around it talk about binding events to objects etc.
Can anyone confirm this is the case, or something else is causing the error with 1.4.3
I have a single webpage that contains information on all 50 U.S. states. There are 50 links at the top to jump down to the state you want, and at the bottom of the information for each state a Back to Top link.
I'm making the Back to Top link into something more complex, and it will require three or four lines of code.
So that I don't have to repeat the code 50 times, and create a burden when I need to edit it, I want to place it in a .js file and call it x. Then below the information for each state I'll simply have:
Does calling code from a .js file 50 times slow down the page load? Which method would load faster?
Here is the code, here is loading 11 times the same page, "artsaved.php" when fading out ".userbutton,.menulabel"
$("#articulosg").click(function(e){
Here in other page, doing almost the same is working correctly loading ONE time "spaint.php"
$("#pictures").click(function(e){
Don't know why is working and why is not working at all...
I'm having a problem where the serialize method isn't serializing form elements that are added to the DOM after the page load. Specifically, when the user clicks on a button some elements are displayed in a dialog that are generated from my server and returned via AJAX. I'm converting from Prototype and didn't run into this problem.
View 5 Replies View RelatedI was wondering whether someone could shed some light on the following.
Using inheritance in Java one can override a function f() (or is it
overload?) in the child and then do:
public f() {
super.f();
...
}
in the child to first execute the parent stuff to be followed by the
additional child stuff.
Is there a way to accomplish this in JS as well and if so how?
I've already figured out the normal inheritance bit and complete
function overriding. I'm just looking for the above case.
I have a few String prototypes such as String.prototype.EscapeReg = function () { return this.replace(/[-[]{}()*+?.,\^$|#s]/g, "\$&"); }; // Escapes characters for use with a regular expressionI also have my own class/ library which is used like this var adg = new AndyG_ns.ADG_Utils(); adg.StartClock('AndyClock','dd mmm yy hh:nn'); // etc.What I would like to do is to only add the prototype to my library (not to the global namespace). The end result I'm looking for is to use code such as:
var adg = new AndyG_ns.ADG_Utils();
var myString = new adg.AString();
var parsed = myString.EscapeReg();
In addition, I want to be able to also use/create my special string sub-class within my library. I suppose I'm saying that I would like to extend or super-class the native String object.
I have 2 page. one of them,is gallery.html and another one, is index.html.i want to load the content of the gallery page into <div id="content-gallery"></div> in index.html.I use the fallowing code :
$( 'a#gallery' ).click( function()
{
$( '#content-gallery' ).load( 'gallery.html' );
});
but it works only in IE8,FF, and safari. It doesn't work in chrome and opera (latest version).In opera and chrome, when i click on <a id="gallery">show gallery</a> it show only a bank page.i use jQuery Library v1.3.2.
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:
var x = function (n) {return n+1;};
what is the relationships of x, Object.Prototype and Function.Prototype
I am trying to get to the bottom of javascript object, prototypes etc. I have a fairly good grasp of it, but I get confused the closer I get to the base object.prototype. FIrst of all, I was under the impression that all objects descend directly from Object. But some objects (like Array) seem to inherit properties and methods from the function.prototype. So does this mean that the chain is like this:
object -- function -- array Second, I noticed (on the mozilla javascript reference site that object.prototype inherits properties and methods from function.prototype and vice versa!? How can this be? I must be missing something important about understanding the chain?
Code:
function BaseController(el) {
var that = this;
this.defaultAction = function() {

What is the proper method here so that el will be defined in the super "class".? I know I saw something on stack overflow a couple of days ago but can not seem to find it again.
admin: Something is up with the code tags, why the system is double posting the code. Does HIGHLIGHT=JS not exists anymore? – That seemed not be working.
I have two methods and I would like to call somename1 method from within somename2 method. I have tried several ways to do so however I keep getting "TypeError" or "RefernceError" I have tried several ways to reference but I am still unable. What am I doing wrong. I would think this would be easy to do.
View 1 Replies View RelatedI'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.
Why 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?

QUESTION ONE: When is use of the jQuery prototype object appropriate, and when is it not?
BACKGROUND:I am still trying very hard to identify the error that is prohibiting me from incorporating a jQuery plug-in into my site in a manner similar to the way that the author of the plug-in has incorporated it into his.Although I have sought consultation with the author, he appears uninterested in working with me.My still fledgling knowledge of jQuery tells me that the author of the plug-in and my implementation of his plug-in are constructed differently.Whereas I use jQuery's prototype property to reference my method and then assign my method anonymously to my HTML document as follows: $().myJQMethod().The author of the plug-in does something very different.I have extracted from the author's plug-in and my implementation of it. Links to the source pages have been included.
CONSTRUCT A (The jQ_Impromptu Plug-In):
(function($) {
$.prompt = function(message, options) {
})(jQuery);[code]...
QUESTION TWO: Although I am able to implement the author's method, it is not performing as it should. When the alert box appears with focus the hosting HTML page is suppose to show through with dimmed opacity.My implementation does not achieve this effect. Firebug has alerted to me to the following breakpoint, but I am poorly unable to interpret it.
I read the documentation on the noconflicts() to mean that Prototype should be loaded first and then:
<script
This all worked great in all browsers except in IE8 which had no clue what jQuery() meant. IE8 says jQuery is undefined.
So I reversed the order of loading, jQuery first then Prototype, and now everybody is happy. Did I just read the documentation wrong or is there something else here I should be worried about?
