I 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.

What I am trying to do is loop through an array, and update / animate the CSS properties of the div.[code]I am able to loop through everything fine, but I cannot for the life of me get the css properties to update. Here is where I am at within the loop. I cannot figure out how to target the class.[code]
View 1 Replies View RelatedI have a bunch of dynamically created divs which I need to loop through and then display text inside which is obtained via AJAX.
<div class="appStatus" id="appStat_1>TEXT FROM PHP PAGE</div>
<div class="appStatus" id="appStat_2>TEXT FROM PHP PAGE</div>
<div class="appStatus" id="appStat_3>TEXT FROM PHP PAGE</div>
Basically, I want to loop through all divs where class = appStatus and on each iteration pull data from a PHP page (via AJAX) to display in the DIV. I need to send the value after the _ of the id (which I can obtain using substring) with the AJAX request in order to return the correct text.For some reason.I know that I need to do something with
$("div.appStatus").each(function() {
)};
Just got myself lost in everything I tried.
Trying to add a new property to a non-jQuery object from inside each loop doesn't appear to work:
var arguments=new Object();
arguments['ticket']=ticket;
arguments['email']=email;
arguments['module']=module;
arguments['epoch']=new Date().getTime();
var total=0;
$('select.category').each(function(){
var name=$(this).attr('id');
var option=$(this).find('option:selected').val();
total+=parseInt(option);
arguments[name]=option;
});
The 'total' variable works as expected. The the 'arguments' variable doesn't. Almost like
a variable scope issue or something. If I put some extra debug code to print out all the
property/value pairs, outside each loop I only see original four, and inside each loop only
the new one just set and none of the original four.?
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?

I guess I'm mainly looking to see if there is any magic involved with add and removing classes in this particular mess I have above.

How can I loop the animated object with javascript? it will be grateful if someone can give me some hint....
here is the code I managed to achieve so far,code...
lets say I have
Code:
alpha.numeric.1.array
alpha.numeric.2.array

how would i go about getting the data in the array? my current thinking is

for(index=0;index<=3;index++;)
{
alpha.numeric[index].arraykey;
}
I am trying to build a config object for a program using a loop. Here's what I've done so far (note: "bbtags" is an array built like this):

That is, every part in red is "name".

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.

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
