Is there anyway to have a CSS class returned as an object? This would be rather useful to feed, for example, to the .animate() function. There is no way to animate directly to a CSS class as destination, is there?
View 5 RepliesI have an each loop that goes through all the elements in a certain class. What I need to do is get the ID of the current element in the each loop, but I can't seem to figure out how to. var currentID =$(this).attr ("id"); was my first assumption, but it's not working. [code]The css is just for debugging, not the goal, so alternate ways for me to do that won't help.

View 6 Replies View RelatedI have a javascript object which dynamically generates a table adding, deleting and moving rows as the user clicks on buttons or links. Problem is when I generate a table row and add the javascript method call to my class, I have to put the object instance name variable of the class in order for it to be called from the onclick=function(). This is seriously limiting, but I'm stuck for a way round it. Heres a edited of the code so you get the idea....
Instantiating the object :-
var dtl = new DynamicTableList("table1", $
{myObject.allFieldsAsJavaScriptArray}, true, true, true);
My javascript class DynamicTableList, note the dtl javascript object
instance variable being referred to in the addRow function. How can I
avoid this???
function DynamicTableList(thisObjName, tableName, options, showDelete,
showUp, showDown)
{
this.processRow = function(r, row, up, down)
{
...
};
this.processRows = function()
{
...
};
this.getVisibility = function(visible)
{
...
};
this.delRow = function(button)
{
...
};
this.addRow = function(selection)
{
...
if (showDelete)
{
var cell2 = document.createElement('TD');
var inp2 = document.createElement('IMG');
/
************************************************** ***********************************************/
inp2.onclick=function(){dtl.delRow(this);} // Have to specify
dtc!!!!!!!!
/
************************************************** ***********************************************/
inp2.title='Delete'
inp2.alt='Delete'
inp2.src='images/delete.gif'
cell2.appendChild(inp2);
row.appendChild(cell2);
}
...
tbody.appendChild(row);
this.processRows();
};
this.moveRow = function(node, vector)
{
};
}
Obviously the code dtl.delRow(this); is being dynamically generated, but how do I replace the dtl instance name with something that'll work whatever the user of this class calls the instance of it!
I've been writing a slideshow script that I've had working perfectly on my mac in Chrome and Safari, however I went to look at it in IE8 and lo and behold it falls over. It says 'object doesn't support this property or method' in relation to the new SlideShow line in the main() function.
View 3 Replies View RelatedThe problems with the setTimeout and setInterval functions provided in Javascript are twofold. First, you can't call a local object method without losing your scope, and second, you can't pass objects to the function, since the function call is implemented as a string.
The Timer class solves these difficulties by employing a static array to store the parent object and function arguments until the function is called.
This class is provided as-is and pro bono, so go ahead and muck with it if you see things that could be done better.
Thanks to WA for giving me the idea for this (albeit indirectly)!

I have created a class array (or variable that contains an array) and am trying to add an element to the array when a new Element object is created. Thus, the line of code to add a new element to the array is within the Element object's constructor function. However, the browser just gives me an error "object expected on line 9", the line of code trying to add an element to the array.
Are arrays not functional within objects? Or, is it that the array is made as a class variable?
Code:
function Element() {
// INSTANCE VARIABLES
this.name = "newElement" + Element.total_elements_created; // GIVE UNIQUE NAME
// INITIALIZATIONS
Element.element_count ++; // INCREASE TOTAL NUMBER OF ELEMENTS EXISTING

Is there any way to call a method of a 'class' in without creating an instance of this class?
View 2 Replies View RelatedWhat I have been doing so far to make a "class"/Reusable object is this:
PHP Code:
function Dog(){
this.name name;
this.bark = function(){
[code]...
However, recently I have been reading a book on Javascript and it said that the problem with this way of doing it, is that the bark() function will be loaded into memory for each Dog object created this way, while the body of that function is the same for each object.
- A Person class with a name property and a jump() method.
- An animal class with a isMammal property and move() method.
- A Dog class with a numberOfLegs property and a bark() method which is a subclass of Animal (thus inherits the isMammal property and move() method.
- Each of those classes in its own file.
This book I've been reading is actually pretty good, but at some points it's explanation is not rich enough.It explains that functions are objects and that objects in javascript are just key-value pairs. It says that each function has a prototype property which points to a blank Object(), but you can make it point to something else? or maybe I misunderstood it. I still don't understand how it really works.
Has anyone noticed this behavior before? This really threw me off... I would have expected prototyped arrays to be private to each class instance rather than shared between all class instances.

View 1 Replies View RelatedI 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).

var myString = new adg.AString();

I 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

I'm trying to figure out which selector is faster (assuming that the class 'foo' only appears on input tags)...
$('.foo');
or
$('input.foo');
From what I've seen online, it seems that people recommend $('input.foo'), but in some limited testing it appears that $('.foo') is much faster in both FF and Chrome. In IE, both methods seem to produce similar results. Here is a fiddle with a simple example...
[URL]
Have browsers started implementing native ways to find all elements with a given class name? Would that explain why $('.foo') seems to be faster?
<input type="text" class="class1">
<input type="text" class="class3">
<input type="text" class="class2">
<input type="text" class="class2 class1">
<input type="text" class="class1 class3">
<input type="text" class="class1">
Given the above, how would I select those that HAVE class1, but NOT class2, don't care about class3
So what I want are the items on lines 1,5 & 6 How could the below be modified to achieve what I want, or do I need something completely different?
[URL] The above webpage lists the selector .class.class without an example. I can't find this usage in jQuery document either. I made the following example, but it doesn't work. Could anybody let me know who to use the .class.class selector?

I am attempting to make a menu that has a background image that changeswhen you rollover or click a menuitem. I've got the hover effect working fine with CSS, but am trying to implement the click event via jquery with the following:
CSS:
div.SustainResourcesMenuTabs
{ background-image: url('/images/departments/commdev/sustainability/menu_tab.jpg');
}[code]....
My process is to reset the entire menu to the inactive state, then switch on the active state for the item that was clicked. Eventually, the item that was clicked will display its corresponding body section as well. I've tried using the CSS pseudo-class "active", but since the entire div is the link, that is unavailable. I've also tried multiple variations of addClass/removeClass, toggleClass, and setAttribute/removeAttributebut nothing hasworked so far.
I have a script that fades links on load and im trying to get this to work on everything but the menu link that has the "active" class
Code:
<div id="menu">
<ul><li id="Home"><a title="Home" href="/" style="opacity: 0.6;">Home</a></li>
<li class="active" id="projects"><a title="projects" href="/projects/" style="opacity: 0.6;">projects</a></li>
<li class="last" id="Contact"><a title="Contact" href="/contact" style="opacity: 0.6;">Contact</a></li>
</ul>
</div>

I'm using jquery to make it easy for AJAX calls.
So I create a class: function cMap(mapID){//vars and stuff}
I go and prototype a function: cMap.prototype.loadMap = function(){ //jquery AJAX call }
Now in the jquery $.ajax({...}); call, I use an anonymous function on the "success:" call: success: function(data){ this.member = data; }
My problem is that inside this anonymous function call I'm trying to call a class member of my cMap class to store the data in from the AJAX call, but it's out of scope. So the JS console in FF/Chrome throws errors about bad value/doesn't exist.
How can I access this class member from inside an anonymous function? Or at least what's a good way to go about doing all this?
