JQuery :: Image Gallery Sequential FadeIn Function
May 9, 2011I'm trying to create an image gallery using a ul with an id of #gallerylist,where the images are contained in the li items. I would like the images to .fadeIn() sequentially, i.e. looping through the li items one by one. I've had a go with the .each() method, but the images all appear together, which isn't what I'd like.
Here's my basic code so far..
$(function () {
//select first image from the gallerylist ul
$('#gallerylist li:first img')
// once the image has loaded...
.load(function () {
// set the image hidden by default
$(this).hide();
// select the li container for the image
$(this).parent()
// remove the loading class .removeClass()
// then insert the image
.append(this);
// fade the image in $(this).fadeIn('slow');
})});
How To Know Execution Time Of Any Function

JQuery :: Deferring Execution Within A Function?
Aug 8, 2011I currently have a situation where I have images that load when a user scrolls to the bottom of a page. I also have part of the same function call .remove() on the top 2 images if the number of currently loaded images exceeds 10. The trouble that I am having lies in the .remove() is causing the scrollbar to move down, calling the image-loading part of the function again (essentially a chain reaction of image loads and elements being removed if a user scrolls down while images are being loaded).
I was wondering if I can use setTimeout or a similar function to prevent .remove() from executing until images have been completely loaded?
$("#message").html(calcScroll);
if (calcScroll == 0 && curPageIndex + 1 < totalCount) {
$("#message").html("loading new images");
window.setTimeout(function () {

Execution Of Function Bar - Returns Undefined
Dec 12, 2011Suppose we have following javascript codes: Case 1.
var foo = function (){
var x = "hello";
var bar = function () {
alert(x);
} return bar;
} var bar_ref= foo();
document.write(bar_ref()); // it pops up "hello" and print-outs "undefined".
If we modified above code slightly, shown as follow: Case 2.
var foo = function (){
var x = "hello";
var bar = function () {
alert(x);
} return bar();
} var bar_ref= foo();
document.write(bar_ref()); // it only pops up "hello".
As you can see, Case 2 modified the return value from "return bar" to "return bar()," which won't cause the "undefined" output. To me, it looks like when the JS interpreter executes the line "bar_ref();" it triggers the execution of function "foo", besides both "return bar" and "return bar()" do the same job which is to execute function body of "bar".
The only difference is that after the execution of function bar, its function body does not exist anymore, so when the interpreter executes the line "return bar;" it follows the function identifier "bar" and ends up with "undefined". This is why the Case 1 gives us "undefined", but I am not quite clear about why the Case 2 can trace down to the function body of "bar". Do you have any ideas about such difference outputs?
How To Avoid The Execution Of A Function At The Time Of Defining.
Mar 18, 2007How to avoid the execution of a function at the time of defining.
Here i am giving the details.
I am creating the following div container through DOM.
<div id="content">
<a href="#" onclick="displayDiv('content')" Click</a>
</div>
The Code is:
var category_list = document.getElementById('category_list');
var dom_div = document.createElement('div');
dom_div.id = 'content'
var dom_link = document.createElement('a');
dom_link.href ='#'
dom_link.onclick = displayDiv();
val = document.createTextNode('Click');
dom_link.appendChild(val);
dom_div.appendChild(dom_link);
category_list.appendChild(dom_div);
The displayDiv Funcion
function displayDiv()
{
dv = document.getElementById('content'); //Here is the error.
}
The Problem is when the following script:
dom_link.onclick = displayDiv('content');
is executed it is calling the function displayDiv(name)
Here we have the code
document.getElementById('content');
which throws the error.
The reason is the div container is not yet created.
What I need is the function should be called only on the click event. It should not be called while I define it to the Click Event. (ie it should not be called at the time of defining)
How to achieve this.
How To Make Sure A Function Completes Before Continuing Execution.

Slide And Stack Sequential Content?
Oct 4, 2011I'm look to create a kind on instruction manual where the user can slide through pages. Rather than using an image slider, which scroll's through the images (or content), I want to stack the pages on top of each other.1. Click NEXT and Page 1 slides into view.2. Click NEXT again, and Page 2 slides out on top of Page 13. Click PREV and page 2 slides back, out of viewI started a fiddle here, showing the slide of page 1. But I'll need a way to count the pages, and for the NEXT and PREV links to know which pages to slide.

Function To Call A Function In All Child Frames
Oct 16, 2006I have a document that can contain any number of iframes which have
further copies of the same document (and so on). In practice, we
shouldn't ever have frames within frames, but I'd like to make the
implementation a general case.
Various of the functions in the parent document need to call themselves
in the child documents with the same parameters as they've just been
passed.
Now, I can stick a loop in each function that goes throught the
window.frames array and calls the function for each frame, but for I'd

It's at this point that my brain explodes. If I limit it to a single

Call The ValidEmail() Function In The SubmitIt() Function?
Apr 22, 2009I'm in the middle of a JavaScript class, and I've run into a problem with one assignment. ^^; I've been given a pre-written script and HTML code to work with, and am required to modify it. Here's one thing I have to do, via my instructor:
Add an "email" field to this form. This field should also validate as a valid email address. (Hint: after adding the form field to the form itself, your next step will be to expand the function named submitIt() by adding a second if statement to confirm the contents of the email field. You will want to paste into the header and use the validEmail() function which you will find in Script 7.15, highlighted in red on pages 192-3 of your textbook.)
I know how to write the code to validate an email address, but I can't figure out how to call the validEmail() function in the submitIt() function. The code I have now just blanks out all the fields when I hit "submit." Here's the part of the script with the email validation:
window.onload = loadDoc;
function loadDoc() {
resetForm(document.forms[0]);

This is a very basic version of what I am trying to do. I have a dynamic list which is set in a table. When clicked, a function is run to set up a new list.. The reason I explain that, is that I need to keep it dynamic.Now for the problem:When I run this page, I have the button made right away, then when clicked it creates the new button. The new button should also run the function to create the new button again, but when I click it, I only receive "error on page".
Call Function Only If Another Function Does Not Return Error?
Feb 14, 2011I'm trying to "progressively enhance" one of my surveys using javascript. Basically, I have rating scales that make use of radio buttons as each point on the scale. Each radio button occupies its own cell in a table. I wrote some functions that will highlight cells on mouseover in a color corresponding to its position on the scale (e.g. the lowest point is red, the midpoint is yellow, the highest point is green). When a radio button is clicked, the background of the button's cell and preceding cells in the same row will be colored accordingly. The functions are working well in FireFox and Chrome (I just have to add a few lines using the addEvent function to make it compatible with IE).
The effect looks a lot nicer when I add a function that makes the visibility of the radio buttons hidden.
However, I want to make sure that there is a fallback option in case the functions that color the cells don't work for whatever reason. I would not want the radio buttons hidden in this case.
Is there a method whereby I can call the "hideRadiobuttons" function only if the other functions are successfully executed?
Call The Returned Value Of A Function Without Calling The Function?
May 13, 2011I am creating a little word guess game, with a random function which picks the word from an array of 10 words. The second function checks if the users' letter choice is part of the secret word. Currently, each time the checkGuess() function is called, the word is changed, probably because I am calling the wordPicker() function from within. The wordPicker randomly chooses the word, then returns that word. All I want to do is pull that word into the checkGuess function, without calling the wordPicker function as it currently does. Here is the code:
Create secret word array
var wordList = new Array("stealth", "telephone", "internet", "nickel", "marine", "instantiate", "method", "function", "television", "monitor")

Difference Between A Function Pointer And A Function Call?
Mar 11, 2011I'm working through the sitepoint ajax book and had a problem with a particular chunk of code. I eventually tracked down the error and it was being caused because I had:
window.onload = Monitor.init();
instead of:
window.onload = Monitor.init;
Now, one of the sticky threads mentioned that the first is a function call and the second is a function pointer. My questions are:What's the difference between a function call and a function pointer? Why did it cause problems in this particular case? What are the general implications/issues with using one over the other?
Function.call And Function.apply
Aug 25, 2006Is this correct? The following three lines are equivalent, for
example, [1] can be replaced with [2] or [3] anywhere in a script
without changing the return value and without changing any side effect.
[1] var r = o.f(a,b);
[2] var r = o.f.call(o,a,b);
[3] var r = o.f.apply(o,[a,b]);
( o is an object and o.f is a function. )
The following three lines are equivalent:
[1'] var r = g(a,b);
[2'] var r = g.call(this,a,b);
[3'] var r = g.apply(this,[a,b]);
( g is a function, for example,
var g = function(a,b){return [this,a,b];}. )
