I have a menu that is made from a ul element (with li children).
Here is an example:
<
ul id="menu" >
<
li><a href="#divEntire2">Home Page</a></li>
[Code].....
However, if I do something like $(this).css('background-color','maroon'), the text and a section of bar under it does turn maroon. This happens even I just click on the bar.
Below is the IDL definition of the HTMLOptionElement.
interface HTMLOptionElement : HTMLElement {
readonly attribute HTMLFormElement form;
attribute boolean defaultSelected;
readonly attribute DOMString text;
attribute long index;
attribute boolean disabled;
attribute DOMString label;
readonly attribute boolean selected;
attribute DOMString value;
};
You will notice that the 'text' and 'selected' properties are marked as
read-only. This adds an interesting dilemma: how do you go about
programatically modifying these properties, especially considering the
need to assign to 'text' when creating a new object? Would you add a text
node, as you find in HTML, to represent the text displayed? If that is the
correct approach, it still leaves 'selected' inaccessible[1].
Something that I did notice is that the ECMAScript bindingsdon't mark any
properties as read-only, and assigning to 'text' is possible, certainly in
Opera. Is that because there is no concept of read-only, so the browser
can choose to ignore assignments, or some other reason?
I've been working on a function to convert nodeList and object properties to an array. The first question is with regards IE and checking whether the object provided is an HTML collection. The best I have come up with so far, is to test if it's an object, has an 'item' which is a function and has length. The second question is with regards slice.call and a while loop copy. I guess I need to do some profile/timing tests, but I'm wondering if the function merits a slice.call? or should I simplify?
Code JavaScript:
// Some weirdness in IE regarding nodesList and typeof 'item' returning 'Object'
// even though when alerted it returns 'function (){...}'.
// Therefore having to use regExp.test() to check whether it's a function instead.
// Note: _isNodeList isn't full proof. An object with the properties

I'm working on a DHTML Client side app (runs on the local system) which needs to query a list of files in a particular directory. I know how to read files in from the local files system. And i found what i think is the relevent code from the Mozilla Development Center, however...i'm uncertain how to put the code together. One of my goals is to write a File-Manager in DHTML which can be used on the local file system :) Moz Dev page: [URL] here's the code snipped for reading in a list of files:
// file is the given directory (nsIFile)
var entries = file.directoryEntries;
var array = [];

how to add extra properties to html elements as I was storing data in html attributes. After looking at some others code including Raphael and this addEvent code. [URL] They seem to treat objects just like an array. obj[property] = value; This would have been extremely helpful to know previously as I have needed to be able to include variables in property names - but have resorted to making the whole thing a string and calling exec() on it.

Is there a way in Javascript or Jquery to return an array of all objects underneath a certain point, ie. the mouse position.

I am trying to get the url and name from a series of links inside a div. I can change from name to ID if necessary, but can't be 100% sure they would be unique within the page. My test is like so

For example, I have the following piece of code:
I have found I cannot access the selectedIndex property unless I preceed by get(0). Am I missing a simpler way of getting at not jQ properties from a jQ object?
I have a billion elements that all share the same class. I have another billion elements that all share another class. This cannot be changed. My objective is to use one element to trigger onclick a change in the others elements' css properties, that is each element is paired with another, producing a billion unique pairs. From hours of deciphering the cryptic documentation examples ive come up with the following, which doesnt work. Assume that im using "name=item#" in the element's tag to identify each pair.
One fundamental issue with this is that it will change the opacity of both elements in the pair were both elements to share a name,or it will only affect the element being clicked on if not, but i only want it to change the opacity of the element that isnt being clicked. Another issue is that there are instances where i may need to set a setTimeout on a css property, and ive not found any documentation on integrating javascript and jquery together within a function.So how do i get this function to accept input from one element and affect the css properties of the other? And what would a setTimeout look like if it were placed around the opacity property?
I'm not sure this is the right group to post to, I've just found this group.I notice the old alt.dhtml group has been murdered, overwhelmed by spam. On my page: [URL] I am trying to get an element's style.top, style.marginTop, and backgroundColor. I can successfully do getElementById( ) on the element, but I can't get any settings from the element. If you bring up the page, all of this stuff is supposed to display in a header-like line just under the small banner. I can see that the doc's scrollTop has been retrieved OK (it wiggles if you move the vertical scroll bar) but all the other stuff is MIA. What am I doing wrong that I can't get this element's style properties? In the source, the function 'scroll(),' which is trying to read these
properties, is at line 52.
ie. the equivalent of typing them in a style sheet, but doing it dynamically?

View 6 Replies View Relatedi'm looking for the best way to use global properties that defined at class level insid event handler functions.
for example :
function MyClass() {
this.v1 = "hello";
this.v2 = {name: 'joe', age:'30'};
this.link1 = $("<a/>", {id: "link1"});

actually, in link1Handler 'this' returns to link1 not to main class. so how to get class properties or functions inside the private functions of the same class?
I want to be able to pass the width of a window to CSS properties. Specifically I would like the width and left-padding of a DIV to be the exact pixel width of the browser window. Ideally, if the user resizes the window, the CSS would update. What is the simplest way to do this?
View 4 Replies View RelatedI'm kind of new to learning javascript so please consider the following code:
orderUser = {
products: [ 'Beer', 'Soda', 'Wine' ],
users: [],
regUser:function(){
varnew_user_id = 12;//normally this wouldn't be a static number ofcourse
orderUser.users[orderUser.users.length] = new_user_id;
}}
There's an object that has some properties and a method. The method registers an user id to the users property. What I'd like to do next is keep track of what users have ordered. Is this possible with (multidimensional?) properties? Something like
userProducts[ 12 ] = [ 1, 0 ] //Soda, Beer
doesn't work. Would there be no other way than arrays?
This object was passed to my click event handler. Why are so many properties missing? The click event came from an <a> in a <li>, propagated down to the <ul> on which the handler was set.
If I click on the <ul>, the event object looks "normal".

I have an object on the document element that allows for other components to register with it, i have a custom event something along$(document).bind("register",function(thechild)..So in the child object when they are created i call$(document).trigger("register",this);And indeed i get the DOM object. However i'm looking for the plug in object, i want to be able to call methods on the passed childobject and access it's Config.Does that make sense? How can i write a plug in that is applied to various objects that also registers itself with an 'overseer' object on the document element in such a way that i can allow that overseer object to call methods on any registered child objects?

where can i find an example of how jQuery selects objects when using an id selector? i'm asking because i've been using a cross browser snippet to select objects and i was wondering if it's the right move to move from the snippet to jQuery. the snippet checks to see for availabe methods and depending on the one that works, it knows which browser the user is using and selects the object using that method. i also know jQuery is cross browser, so it's kinda implied, just wanna make sure.
View 1 Replies View RelatedBasically i have a good experience and knowledge with prototype.js library and also at the same time i am willing to get deeper into jquery.
I very much use oops concept now a days in almost every problem i solve using javascript, and was doing with prototype's feature to create classes and objects. Since i am now looking to get deeper into jquery, i was looking to find similar feature in jquery as well. I suppose jquery must be having a feature to create classes and do inheritance programming, but i couldn't find the way. My question to the forum is, Is there any option/feature in jquery which helps us to create classes and objects of our own probably with the support of inheritance?
