Difference Between Object.prototype And Function.prototype?

Nov 25, 2011

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

How Come Object.prototype Inherits From Function.prototype

Dec 14, 2009

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?

Ajax :: Return Xmlhttp.responseText From Function?

Jun 9, 2011

I've been racking my brain for a couple hours now and doing a lot of searching and I cannot seem to find an answer. I want to know if it is possible to return the xmlhttp.responseText value from an AJAX function to the function that originally called the AJAX function.

Code:
//Set handler for server response.
xmlhttp.onreadystatechange = function()
{

[Code]....

I want to return the my_response variable to the original caller. No matter what I try I have been unsuccessful. I even tried assigning it to the global window variable using window.my_response = xmlhttp.responseText but it ends up being undefined.

Every example I've seen of using AJAX pretty much does something inside of the if (xmlhttp.status == 200) part to update the web page. I really do not want to do that.

Can I return the value?

How Can I Stop AJAX PeriodicalUpdater

Sep 16, 2007

'statusDisplay',
'returnStatus.lasso', {
method: 'get',
parameters: 'fw_s=sid',
frequency: 2

IE And Array.prototype Function?

May 5, 2010

Array.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.[URL]..

Array.prototype.push = Function() {

May 7, 2007

I found this code on Internet:

<script type="text/javascript">

Array.prototype.push = function() {
var n = this.length >>> 0;
for (var i = 0; i < arguments.length; i++) {
this[n] = arguments[i];
n = n + 1 >>> 0;
}
this.length = n;
return n;
};

</script>

Question 1: How to call this function?
Question 2: When I delete >>> 0, what I lose? ( >>>0 &#305; sildi&#287;im zaman, ne kaybederim?)

Overwriting A Prototype Function And Keeping Scope?

Nov 3, 2010

Not sure if this is possible, but I have an external script that creates an object, and I want to overwrite some of its functionality, but keep the scope.

Here is a basic example:

Code:
<script>
Obj = function (userConfig) {
this._init(userConfig);

[Code]....

I want it to log two Objects, but instead I get two window elements. Is this because I am declaring the functions in the global scope, and not from within the object?

Anyway I can keep the scope of the object, whilst still overwriting the function?

JQuery :: Plugin - Function (Prototype) Test Unknown

Jan 8, 2010

I want to write a plugin, say 'myPlugin' which I can use like
Code:
$('#myID').myPlugin() ;
$('#myID').myPlugin.test() ;

The plugin I wrote looks like
Code:
(function($){
$.fn.myPlugin = function() {
// do something
} $.fn.myPlugin.test = function() {
var $this = $(this) ;
// do something ;
}})(jQuery) ;

This works and it doesn't work. It works because test() is called, but this is not the element with id '#myID' it is $.fn.myPlugin. To fix this I tried the following
Code:
(function($){
$.fn.myPlugin = function() {
// do something
} $.fn.myPlugin.prototype.test = function() {
var $this = $(this) ;
// do something ;
}})(jQuery) ;
but now the function 'test' is unknown.

JQuery :: Bind Variables To A Function Call (like In Prototype.js Function#bind)

Nov 4, 2010

is there a way in jQuery to bind variables to function calls similar as prototype.js does it? See [URL]

E.g. in the slideUp method of jQuery you can specify a callback that is called after the effect has finished. I would like to bind a variable to this call so that it is used inside of this callback as a closure.

Position Reporting Function: Flanagan, Yahoo!, Kruze, Prototype ... All Broken At Least A Little.

Oct 9, 2006

It seems like determining element position in a web page is a difficult
task. In the position reporting source code I've looked at there are
special fixes for at least some versions of Safari and Opera. I am
doing a lot of dragdrop experimentation and in some situations need a
position reporting function. The function doesn't need to report the
positions of exotic elements like images in button elements; however, I
would like a position reporting function that can at least handle
combinations of scrollable elements and tables....

Calling A Function With Prototype Property - Alert Message Returns In One Instance: 'someAnimal Is [Mammal "Mr. Biggles"]'

Jun 12, 2010

In the below code, the alert message returns in one instance: 'someAnimal is [Mammal "Mr. Biggles"]' I don't understand how this is possible. We pass as an argument 'Mr. Biggles' to the Mammal constructor. Then assign it to the object name property. But then it ends there. There is a function called toString which will return the alert. But the toString function is not being called like this: alert('someAnimal is '+someAnimal.toString()); If it was like how it is above, it would make sense to me but now it makes no sense to me because I don't see where that toString() is being called - I only see that it is prototyped to the Mammal object.

Code:
function Mammal(name){
this.name=name;
this.offspring=[];
}
Mammal.prototype.haveABaby=function(){
var newBaby=new Mammal("Baby "+this.name);
this.offspring.push(newBaby);
[Code]....

? In XMLHttpRequest.ResponseText

Feb 25, 2006

I'm fetching some HTML files with XMLHttpRequest and dumping the
ResponseText into block elements; works fine except that single and double
quotes are being displayed as question marks (inside of a black diamond in
FireFox)

What's going on ? What is the workaround ? I've tried this:

divElement.innerHTML = x.responseText.replace(/?/g, "'")

but it does nothing ... even if it did work it would not be distinguishing "

IE ResponseText Is Empty

Feb 24, 2011

I'm trying, to fill a table with data I receive from a Servlet. In Chrome everything works fine. But when I try the app on IE the responseText is allways empty. The following is my JS code (using prototype):

function updateToDeleteTable(){
var url = 'getDefHidConFechaInsercionMayor?plantacion_id='+$('plantacion_id').
options[$('plantacion_id').selectedIndex].value +
"&fechaDesde="+$("dateSelect").options[$("dateSelect").selectedIndex].value;

[Code].....

I know the servlet returns a correct text, because when I enter the request uri in a new IE tab it returns the appropiate html code.

Allso when I check the variable response in the IE JS debugger the resaponse of the servlet is 200 (OK). I realy can't think of anything I'm doing wrong, exept, that maybe there is a size limit for the responseText.

What's The Difference Between SomeFunc.blah = Function(){} And SomeFunc.prototype.blah = Function(){}?

Dec 21, 2006

My query is very straight forward (I think).

What's the difference between

someFunc.blah = function(){ ; }

and

someFunc.prototype.blah = function(){ ; }

?Does someFunc.blah call upon someFunc.prototype.blah?

Is there any difference?

Keeping Whitespace In ResponseText, Etc.

Aug 24, 2006

I'm trying to access the source of an HTML page with as few alterations
from the actual source (as in, that seen from the View Source option)
as I can. The method document.documentElement.innerHTML returns the
HTML source, but adds HEAD and other elements if they are absent from
the source, and takes out whitespace (i.e., line feeds, carriage
returns and tabs) within tags and between tags. The follow function:

function xhr() {

xhr = new XMLHttpRequest()
xhr.open("GET","test-page.html",true);
xhr.onreadystatechange = function() {
if (xhr.readyState==4) {
alert(xhr.responseText);
}
}
xhr.send(null)
}

doesn't add or alter any tags that are absent in the source, and does
not take out line feeds within tags; it does, however, still take out
all non-line-feed whitespace within tags and all whitespace in general
between tags.

It seems that preserving whitespace is all that I need, but I haven't
found a way to do that through my searches. So is there any way to get
the unaltered HTML source of a page without innerHTML or applets, like
a better version of the XMLHttpRequest object's responseText method?
