JQuery :: Detect Element Class Change?
Jan 31, 2011I have some legacy code that creates an image carousel and outputs AFTER the document head has been output - the CSS for this was being aded to a style block within the <body> which although worked is not compliant. I am trying to use jquery to set the css, but one part if failing. This is the original css :
#div_tab_one a:hover { .... }
#dic_tab_one .selected a {...}
How can I inject this css ? the selected class is set by some YUI code and rotates through the carousel setting/unsetting the "selected" class.
Detect Broweser+version And Place This As A Body Class In JS?
Oct 28, 2011I've obtained some server side PHP code which places the browser and version (taken from the USER AGENT string response header) in a class of my body HTML element i.e. <body class="ie ie7"> I'm using this as a CSS hook for cross browser styling.
Im running the site on Wordpress with a caching plugin which spits out a HTML version of the page. The problem is, is that the cache doesnt refresh on a per new user basis so if the first user comes in using Chrome this will get added to static file <body class="chrome"> and obviosly wont refresh if the next user is on say IE as it is now cached as a flat HTML.
I'm wondering is there a better way to do this client side and manipulate the DOM after the page has loaded? If so, anyone got any code that can do this?code...
JQuery :: Use Of This Keyword With And Without String
Aug 29, 2011I was reading thegetting started with jquery. And got confused with use of this in these 2 code segments.
$(document).ready(function() {
$("#orderedlist").find("li").each(function(i) {
$(this).append( " BAM! " + i );
});
});
$(document).ready(function() {
// use this to reset several forms at once
$("#reset").click(function() {
$("form").each(function() {
this.reset();
});
});
When do we need $(this) and this? And what is the difference between them?

JQuery :: .click() Event Handler And The 'this' Keyword?
Nov 13, 2011My plan is to create a JavaScript class, with some functions and variables, and one of the functions is called when a user clicks on a certain element. However, I need to find out the ID of the element that was clicked (in the example, that of the <p>) for further processing. It looks basically like the following:
[Code]...
The result was very crazy, because console.log(this) gave me the node as result, and console.log($(this)) did the same only as jQuery node, but trying to find out the attribute via jQuery gave undefined as result. I haven't checked if this.id would work (should probably), but I'd prefer to keep the whole script in jQuery, if possible. I suspect it may be an overusage of the 'this' keyword, but if so, what's the proper way to do it?

View 1 Replies View RelatedSettimeout And This Keyword
Apr 3, 2007I am modifying the suckerfish dropdown code to use settimeout to have
a slight pause before the menus disappear to make it more user
friendly. I have hit a snag with the following statement:
li.
{
timerID=setTimeout('this.getElementsByTagName("UL")
[0].style.display = "none"', timecount);
}
If I put take the statement
this.getElementsByTagName("UL")[0].style.display = "none";
out of the settimeout function, it works. (w/o the pause, obviously).
With the settimeout function, I get "this.getElementByTagName is not a
function" error.
I have tried putting this.getElementsByTagName("UL")[0] is a variable
and then using that in the settimeout function, but then each li will
only open the very last menu in the list. (ie all the menu items open
the last sub menu) Code:

Grab The 'this' Keyword Position
Sep 8, 2006Is there a way to find which element in an object array the keyword 'this'
is acting upon?
For example:
function doMe(){
var aTags = document.getElementById("list").getElementsByTagName("a");
for (var i=0; i<aTags.length; i++) {
aTags[i].onclick=function() {
this.className = "myClass";
}
}
}
Inside of this function is there a way to determine where in the array this
'this' is and return the integer?
var theID = this.somethingOrOtherThatWouldGiveMeTheNumber;
var elementID = document.getElementById("myDiv"+theID);

Keyword In Callback Within Object.
Apr 27, 2007I'm creating a list with buttons that show and hide some of the list elements to create the effect of scrolling. I've built an scrollList object so I can apply this to any list. When you create the object and pass it the id of the <ul> and how many items of the list you want to be displayed. It will add the scroll down and scroll up links and add an Event.observe to them (I'm using the Prototype library).
This code creates the object
var main_news_articles;
main_news_articles = new scrollList('main_news_articles', 5);
main_news_articles.init();
The problem I am having is with the callback functions of the onclick event of the links (scrollUp and scrollDown). The this keyword within these functions is refering to the link and not the object.
To try and solve this I've made the title attribute of the link the same as the variable name of the scrollList object. I can reference the scrollList object like so Code:
Detect URL & Detect Something On Page & Show Content Accordingly?
Feb 14, 2009Can Javascript be used to detect a certain url and then "not" write some html according to that url and also detect something on the page and "then" display some html?.
Example: I'm working on a volusion site that uses asp. There's basically only one page that's changed dynamically. I would like to display some html when and only if the cart has any items in it. But also not to show up on the check-out pages.
The page dynamically displays "Your cart has 1 item in it..." when the visitors puts something in their cart.
So could javascript detect when this is displayed then write some html and then also detect if the url is showing the cart and then not show the html?
Retrieving Keyword In Alert Box To Welcome Visitor
Aug 13, 2010I am looking to insert a keyword in to a javascript alert box when someone visits my website, so say they came from codingforums, it would say "Welcome, CodingForums.com Visitor". My keyword will be passed from the ad platform I am working with and shows up correctly in the tracking, so I'd imagine it's just a case of having the snippet of code for it to show in the alert, correct? If there is no keyword, I would just like it to say "Welcome Visitor" or something.

Changing Properties Added With The Prototype Keyword
May 2, 2007I have some script like this:
// simplified to remove all the try/catches & stuff
function newXHR() {
request = new XMLHttpRequest();
XMLHttpRequest.prototype.requested = null;
return request;
}
then later:
function doRequest(url, callback) {
var req = newXHR();
req.requested = url;
// et cetera....
}
This works fine in Firefox, however the line 'req.requested = url' causes an error in IE7, (I haven't tested IE6 yet). The error is 'Object doesn't support this property or method'
So, this leads me to believe that either a) XMLHttpRequest.requested is not writable, or, b) XMLHttpRequest.requested was never created in the first place. I think it's the first option because I'm not getting an error in the newXHR() function.
I've been searching for some documentation on this but I can't seem to find anywhere if properties created with the prototype keyword are writeable in IE. Does anyone know what the problem is?
Handle Objects And The 'this' Keyword When Using Event Listeners?
Feb 24, 2009So I know all about the caviats of the 'this' keyword when calling object functions from event listeners:
Code:
var foo = {bar: true, zoo: function() { return this.bar; }};
foo.zoo();
> true
a = foo.zoo;
a();
>
And I know that I can get around this by using an anonymous function so that 'this' is preserved in it's original context:
[Code]...
But then someone pointed out this article on memory leaks when using anonymous functions to call object methods because the anonymous function gets access to ALL variables in the enclosing environment and my not be properly disposed of by the garbage collector [URL] So that lead me to think about using a "3rd-person" approach to referencing object properties from within object methods.

JQuery :: Assigning A Click To A Class Selector - Once Clicked The Class Is Removed - Does This Work
May 5, 2011I have a huge blob of code but the main part I am focusing on is this
$('.billboard_click').click(function () {
//this remove class
$(".billboard_click").removeClass("billboard_click");
});
1. Execute a click event when the div with the class 'billboard_click' is clicked
2. Once clicked, remove the class from that very div to avoid another click from happening
3. Execute a series of events such as animations, etc
4. add the class back to the clicker div
The code does not seem to work as expected but I am wondering if I am having issues elsewhere at this point and wonder if this actually is known to work

Return Keyword Applied On Object Returns Reference Or Value?
Aug 24, 2010I am confused about what the return keyword is actually returning when returning an object, a primitive, or a function. My confusion is compounded by the fact that I'm not sure if a function is an object or not. According to the book JavaScript Programmer Reference it is: "All functions in JavaScript are first class objects , meaning they can be passed around like any other object reference. In fact, regardless of how they are created, functions are instances of a global object named (aptly) Function."
However, someone else states that a function is not an object. An object is a set of primitives and references. A function is executable code. Functions become objects through the use of the new operator. Yet, in the book I mentioned, it says you don't need the new keyword to execute the function as an object, as it already inherits from the object Function when the function keyword is used:
function functionName([argname1 [, ...[, argnameN]]])
{
statements;
}
So there's one source of contradiction. Now the bigger issue is what is going on when the return keyword is used. Notice the Validation() function returns an object as its last expression. This technique is common, where you return an object which contains functions in form of object notation. I believe this is done so that we create a closure so that when the intepreter exits the Validation() method, since we created a closure by returning an object, which contains the inner functions addRule and getRule, the local variables of Validation() are not destroyed, given that we can reference them through the two inner functions that make use of the local variables of the outer function. So when we use the return keyword on an object literal, and then exit the function, when we call one of the inner functions as we do later:
